Don’t waste time Get a verified expert to help you with Essay

All over the universe, speedy industrial growth of metropolitan metropoliss have ever resulted in a growing in inhabitants and apart from within the basic addition of the size of municipal solid waste generated. The direction of municipal stable waste, if non dealt with decently, will take to assorted jobs now and in the hereafter. Developed states within the universe have, to an enormous extent succeeded in managing their waste utilizing assorted rules and strategies. From suited aggregation methods to technologically superior disposal methods, they’ve made sure that municipal solid waste has been efficaciously controlled in their metropoliss.

Unfortunately, the same can non be stated about different creating states of the universe. Developing states corresponding to Nigeria are still combating with municipal strong waste path. As a direct consequence of the oil roar, Port Harcourt metropolis, the capital of Rivers State, Nigeria ( which is the instance survey of this research work ) has experienced a significant rural- urban migration. The population has about tripled over the old ages.

This has, in bend, led to a monolithic addition in the sheer quantity of stable waste generated throughout the metropolis..

Approximately 168,201 metric tons of strong waste are produced in the metropolis of Port Harcourt every twelvemonth and waste disposal has non been efficaciously dealt with. Residents resort to indiscriminate discarding of their waste at every given chance The commonest companies of waste disposal in the metropolis by the populace are mainly by dumping the garbage by the route, firing the rubbish within the unfastened air of their compounds, littering it brazenly on street corners and apart from dumping them in rivers and watercourses and drainage techniques.

These strategies of waste disposal contribute tremendously to the debasement of the surroundings in so some ways. However, actually small is done to recycle and recycle the solid waste generated. Research exhibits that a immense per centum of the general public do non recycle and recycle their wastes which indicates that the awareness diploma of the populace about reuse and recycling of waste in Port Harcourt metropolis is actually low and presents a batch of likelihood for betterment.

This survey therefore investigates the grounds why correct waste disposal methods are neglected by occupants of Port Harcourt. It in addition to seeks to detect why the tactic of Reuse and Recycle of waste is non acquiring the consciousness and Government support it greatly deserves. Recommendations were made about schemes that may let the authorities and stakeholders involved to progress on fashionable strategies of waste Reuse and Recycling as a nucleus side of municipal stable waste course in the metropolis. Through the usage of informations collated via questionnaires, it was gathered that a bulk of respondents agree that reuse and recycling of waste can positively impression the environment, create gross and besides employment possibilities. It reconnoitres the nexus between reuse and recycling of strong waste as a method to make gross and to lastly accomplish sustainable growth in the hereafter.

Chapter ONE



Harmonizing to Shah ( 2000 ) , strong waste is outlined as any stuff that is unwanted or thrown off. The general neighborhood positions waste as one thing worthless that should be destroyed or thrown off. As such, proper disposal of waste has constituted immense disposal jobs. Peoples normally dump their family solid waste on the route aspect, unapproved garbage dumps and unlawful landfills. This has brought about untold environmental air pollution each bit good as major reverses in social growth ( Mbata 2010 ) . Waste normally is a menace to the setting, because of its adverse environmental impacts that end result from littering, dumping of wastes illicitly, and nursery fuel emanations ( Hosetti 2006 ) . Waste contaminates ground H2O and may do critical wellness jeopardies if non dealt with and managed decently.

In growing states like Nigeria and so Africa in general, industrial growth has enhanced the jobs of speedy urbanisation. In Nigeria today, solid waste path is probably one of the principal jobs faced by the province and local authorities governments in Nigeria. Solid waste course in Nigeria is fundamentally pigeon-holed by uneffective aggregation and disposal strategies ( Ogwueleka 2009 ) . As such, Ogu ( 2000 ) observed that solid waste course continues to remain a formidable problem to most underdeveloped states.

The patterned advance of civilisation in developing states corresponding to Nigeria has tremendously enhanced waste coevals ; doing it even more complex to manage ( Jayarama, 2011 ) . Owing to the turning population of Nigeria, the volume of waste produced is apart from rising in metropolitan metropoliss like Port Harcourt, particularly as it is an oil convey forthing country and the geographic expedition of oil has led to an addition in movement of individuals from rural to urban international locations ( Odiba, 2009 ) . This fast enlargement of cardinal metropoliss in Nigeria, like Port Harcourt, has led to the decrepitude of the setting largely by home waste ( Onyinlola, 2005 ) . Harmonizing to UNEP ( 2009 ) population rising and industrialisation has resulted in speedy addition in the sorts and quantity of strong waste generated on this. Research reveals that resettlement of the folks from rural to city international locations does non merely enhance the gross of the state, however in addition to increases the whole volume of municipal strong waste generated in such countries. ( Adedokun, 2009 ) .

Municipal solid waste disposal strategies are an aspect that raises severe concern in a 3rd universe state similar to Nigeria. The common strategies of stable waste disposal in some states notably Nigeria is by landfill, unfastened dumping on the streets, and by firing the waste in backyards or in an unfastened infinite. Unfortunately, roughly sixty five % of household wastes are dumped directly into rivers or watercourses in Nigeria ( Rakshit 2009 ) . The utilization of rubbish dumps and landfills as waste disposal techniques is one more frequent company of waste disposal in Port Harcourt, Nigeria. This leads to really unfavorable environmental impacts such because the emanation of methane fuel which contributes basically to planetary heating and besides reduces the sum of land available for growth ( Olowomeye 2010 ) . Dumping of waste in landfills besides leads to anchor H2O taint of the full environing countries. Okosun ( 2011 ) in addition to noticed that uncontrolled dumping of wastes by waysides consequences in assorted wellness jeopardies and reduces the aesthetic high quality of the setting. Through research exhibits that the roles related to waste disposal can be traced again to the fourteenth century when the littering of nutrient waste and different strong wastes in the city led to the eruption of diseases that caused the decease of half of the Europeans at the clip ( Bortoleto 2011 ) .

Over the old ages, analysis has regularly shown that the chief ground for solid waste jobs in city countries of developing states is because of high population rising charges and the prevailing poorness ( Affun 2009 ) . The financial and societal growing of a state or metropolis ever penalties in elevated manufacturing and fabrication actions. This, in bend, leads to actions which are synonymous with human being similar to production, fabrication, waste coevals and disposal. As a direct consequence of the procedures of fabrication and disposal of consumables, there is a essential addition of the rate of air pollution. This depletes priceless natural assets and besides releases toxic vitality which pollutes the setting, doing sustainable improvement impossible to perform.

Sustainability as a word has ever been used in our mundane slang. Harmonizing to Hideroni ( 2006 ) it’s outlined able of pure environmental safety, population rising and economic unfold between developed and creating states. Sustainable improvement entails an environmentally comprehensive, value effectual and socially suited course of solid waste ( Roberts, 2003 ) . Sustainable growth is a theory that has to be integrated into the mundane lives of the general public if we want to accomplish a better high quality of life for our unborn youngsters ( Dernbach, 2002 ) . In the recordings of the International Council for Local Initiatives ( ICLI ) , sustainable development is such that provides environmental, societal and financial comfortss to all residents of the society with out interrupting the capableness of the natural constructed societal systems upon which the bringing of these providers rely upon. The chief function of sustainable growth is to renew the severely broken environment and guarantee that coevalss unborn do non confront the inauspicious results of our disregard on the setting. Therefore, strong waste direction with sustainable development in head encourages states to deliver forth less waste, re-use most consumables, recycle and search their extreme best to retrieve and recycle all the waste produced, thereby guaranting that the hereafter coevals are non affected by the impacts of the current coevals ( Mbata 2010 ) . Sustainable growth is a assemble that must be taken into attending for effectual waste course. With respects to this, states all round the universe including Nigeria, are endeavoring to accomplishing sustainability ( Hasheela, 2009 ) . Therefore, all essential stairss and safeguards ought to be taken to accomplish this end


Having a inhabitants of over 165million people and an one-year growing fee of 5.6 % , Nigeria is taken into account the most important state in Africa. Growth price of city countries in Nigeria has increased from 25 % in 1975 to forty six % in 1995 ( George,2010 ) Estimates by the World Bank point out that by the twelvemonth 2005, more than sixty five % of Nigerians would hold migrated to urban countries corresponding to Lagos, Port Harcourt, Delta, Calabar and Abuja ( Alkali, 2005 ) . The cause for this resettlement is basically because of oil geographic expedition activities of oil firms in these nations. As a consequence of this, the wastes generated from these countries have been on the addition and its disposal and effectual direction is a immense problem to the authorities and municipalities concerned. It can be observed that the most important job related to stable waste direction comes roughly because of the huge tonss of rubbish dumped illicitly by the route sides and market topographic points ( Odiba 2003 ) . As horrid because it sounds, it’s still frequent practise in Nigeria to dump waste illicitly with out considered the influence of such patterns on our environment. Waste path jobs in Nigerian metropoliss harmonizing to ( Ogwueleka 2009 ) are typically related to deficiency of concern and engagement from the general populace. He farther said that a lot of the waste insurance policies are made without seting the populace, who’re the chief waste mills, into thought.

The mode, in which waste is controlled in Port Harcourt, Nigeria ( the survey nation ) is a large menace to the surroundings and might do wellness jeopardies ( Hasheela2009 ) . A overplus of wellness jeopardies similar to malaria fever, typhoid febrility, diarrhea, cholera and even skin illnesses have been shown to be the consequences of hapless waste course in any surroundings ( Guobadia 2011 ) . It is gratuitous to state that uneffective waste course is a big hazard to the end of sustainable improvement and if no positive progresss are made within the nation of pull offing waste, there shall be ruinous, long term environmental impacts on the people now and coevalss unborn.



The chief function of this enterprise is to research and detect the assorted ways how the Reuse and Recycling of Municipal Solid Wastes can take to sustainable development and gross coevals.

To arrange, via comprehensive analysis and statistical evaluation that waste Reuse and recycling essentially the most suited methodology of Municipal Solid Waste Management in a underdeveloped state corresponding to Nigeria and can lastly take to Sustainable development.


To measure the various already bing techniques/methods of Municipal Solid waste aggregation and disposal in Port Harcourt metropolis and Nigeria as a whole.

To find, based mostly on an Environmental Risk Assessment, the most important waste associated hazard presently in the occasion analyze nation ( Port Harcourt )

To measure the present degree of consciousness proven by the populace and the present makes an attempt of the authorities in making more consciousness and supplying environmental instruction to members of the populace on efficient, environmental friendly methods of waste disposal such as Reuse and recycling.

To analysis the obstacles that prevents the reusing and recycling of the main constituents of Municipal solid waste corresponding to paper waste, fictile waste.

To cover with Solid waste reuse and recycling as of import sides of nationwide financial system and environmental as a agency of sustainable development and gross coevals.

Literature Review

2.1 Definition of Waste

Waste is a direct effect of human being and exercise. It may be mentioned to be wholly ineluctable. Different definitions of waste abound. It is, however, of import to province that the time period ‘waste ‘ is really subjective. This is as a result of, what one individual might even see as waste could be seen as an object of excessive worth by one other individual. ( Ajomo, 2010 ) . A really rigorous authorized definition of waste to follow with the jurisprudence is hence essential ; as such steadfast definitions of waste have legal, fiscal and societal deductions for the authorities, local governments, concerns, and the general populace ( Williams 2005 ) . In common idiom, waste could be outlined as any merchandise or stuff that is undesirable. Wright ( 1990 ) describes waste as something that has misplaced its public-service company worth in the sight of the unique proprietor and everybody else normally. However, the European Council framework Directive ( waste Framework Directive 75/442/EEC 1975 ) presents a legal definition of waste. It defines waste as

“ aˆ¦aˆ¦any stuff where the holder has an objective to fling the stuff as now not portion of the conventional commercial rhythm of the concatenation of public-service corporation ”

This is the universally recognized definition of waste. Different states may maintain considerably completely different divergences of this definition based mostly on their Torahs, civilization and prevailing times, fortunes and patterns. Harmonizing to the Federal Environmental Protection Agency ( FEPA ) , beneath the protections of Provision Decree 42 of 1988, waste is said to be “ substances or objects which are disposed of, or are intended to be disposed of, or are required to be disposed of by the commissariats of the jurisprudence of the Federal Republic of Nigeria ( Omobolaji, 2010 )

2.2 Categorization of waste

There are various kinds of wastes that could be found throughout us. Different states define/classify waste harmonizing to the province during which the waste is shaped i.e. solid, gas or liquid or the style the waste is generated. Based on this, waste could be classified Industrial waste, household wastes, medical waste, constructing waste, business wastes, radioactive wastes, and so forth. However, generally footings, all most of these wastes can be classed into two chief sorts, viz. Controlled and Uncontrolled wastes:

Controlled Waste

Controlled wastes, harmonizing to the commissariats of the Control of Pollution Act! 974 ( COPA ) are mentioned to be chiefly Household waste commercial/ industrial wastes. It is a UK term covering waste subject to a accountability of attention beneath the Environmental Protection Act of 1990.

Industrial Wastes: these are wastes that are generated as a direct consequence of business patterns. They include waste thermoplastics, waste wooden movie editings and fixingss and so forth. However, they do non embrace fictile medical waste, waste metal movie editings and waste paper ( Environmental Law Library 2010 ) .

Commercial Wastes: They are the numerous waste stuffs gotten from trade and concern edifices and activities.

Family Wastes: Are those waste merchandises generated from actions inside a residential home. Examples of this kind of wastes are backyard waste, paper and composition board, glass, nutrient leftovers, wooden etc.

Non-Controlled waste

Non controlled wastes are categorised as those waste merchandises which may be non underneath the direct management and authorized energy of the suitable local authorization. These sorts of wastes embrace wastes which are as a direct consequence of excavation and quarrying actions, and agricultural wastes and in addition to, radioactive wastes ( Wright, 2003 )

Agricultural Wastes: These wastes are mainly the categories that arise from agricultural activities similar to farm animal litter. They besides embody waste pesticides asbestos roofing stuff and besides waste oil coming from equipment, chemical compounds with risky belongingss and so forth.

Radioactive Wastes: these discuss with blow that comprise radioactive stuffs. They normally originate from atomic power workss, or industries that emit radioactive substances or compounds during the class of their operations ( Barnstein,2009 )

2.three Municipal Solid Waste Management

Municipal stable waste ( MSWs ) refers to all the stable waste generated inside a given municipality. They are chiefly natural and inorganic in nature and are produced in residential locations, office composite, stores, infirmaries and so forth. Although everybody in the society has the responsibility to get rid of garbage in a pleasant mode, municipal stable waste is generally the obligation of the native authorities governments ( Okogbue, 2001 ) . Municipal solid waste is these wastes collected by metropol5ises independent of the chief beginning of waste ( Bernstein, 2009 ) . Such wastes embrace household wastes ; waste produced by concern edifices and little neighborhood outlets. They do non, however, embrace waste from industrial patterns or agricultural strong waste ( Filemon, 2008 )

In the words of Robert Klein ( 2002 ) municipal solid waste refers back to the gathering, transportation, intervention, recycling, and disposal of stable waste in urban international locations. The end of municipal stable waste course are targeted at advancing the standard of the city environment, convey forth employment and income, and protecting environmental wellness ( Ogwueleka, 2009 ) . Harmonizing to Kit Strangen ( 2002 ) , municipal strong waste might include some, if non the entire undermentioned factors:

Street garbage/litter or sweepings.

Household waste ( normally generated from recycling and composting waste deposited by home occupants at waste disposal websites ) .

Hazardous waste ( in little measures gotten from households )

Garden/green waste and

Bulky strong waste besides generated from families.

Municipal Solid Waste path could be mentioned to embrace all the activities that has to make with managing all the waste generated within a municipality, from the purpose of beginning, to the concluding level of disposal. In the words of McGraw ( 1993 ) , “ municipal strong waste course is the subject attender with the management of the coevals, storage, aggregation, transportation, processing and management of disposal of stable waste in a mode that is in agreement with the most effective guidelines of public wellness, economic sciences, expertise, preservation, aesthetics and different environmental considerations and that’s besides antiphonal to public attitudes ” Bloomberg ( 1989 ) described solid waste direction as “ the subject that trades with the management of coevals, storage, aggregation, transportation, processing, and disposal of stable wastes in a mode that is in understanding with the best guidelines of public wellness, economic sciences, saving, aesthetics and other environmental concerns and that is in addition to antiphonal to public outlooks and mentalities ” . The United Nations ( 1997 ) defines strong waste direction as the total procedure of management and supervising of stable wastes from its point of coevals to its finish level of disposal.

2.4 Principles of Waste Management

Solid waste direction has been mentioned to mention to all activities associating to the control, mixture, resettlement, intervention and dealing with of strong waste in understanding with the most effective values of public life and different environmental issues ( Shan, 2000 ) . Therefore, operative rules of waste direction includes of waste bar, decrease, recycling, intervention and disposal within the environment ( Shan, 2000 ) . Failure to efficaciously pull off waste in the surroundings results in fast debasement and it poses long run jobs to everyone.

Research has proven that, so as to successfully pull off waste and understate the detrimental results it has on the environment, some schemes must be adopted and applied:

Waste Recovery ( waste recycling, re-use and intervention )

Prevention of waste coevals

Environmentally friendly Waste disposal.

Figure 2.4: Waste Management Hierarchy ( Source: Liennmann, 2009 )

These schemes are aimed toward cut downing the overall sum of waste produced by promoting proper path of waste. It apart from aims at retrieving each bit a lot value as potential from all of the waste generated. As proven on determine 2.four, waste bar should ideally be the primary attack to blow path before other choices are thought-about ( Klein, 2000 ) . Effective execution of this waste direction hierarchy will take to a decrease within the volume of the concluding waste disposed ( Hasheela 2009 ) . Magali and Bodart ( 2010 ) instructed that for sustainable growth to be achieved, waste direction activities must be devoted towards waste lower, which is on the high of the hierarchy, using the really feasibly finest environmental picks. Therefore the chief purpose of the waste path hierarchy is the decrease of waste at beginning. Waste recovery and reuse should be the secondary purpose as they contain other procedures similar to recycling, composting, and recovery of vitality.

However, latest surveies have proven that the waste path hierarchy scheme is non essentially the most effectual. This is as a outcome of it’s non based on any scientific could non specifically take one of the best system for a metropolis or state to follow. For illustration, the waste direction scheme can non compare composting and incineration ; or recycling and landfilling in footings of their environmental impacts and value ( Letcher, 2004 ) . This goes to demo that the waste hierarchy ought to be followed flexibly as a usher as an alternative than stiffly so as to accomplish a steady environmental, economic and societal resolution ( Raven, 2011 )

Aside from the above mentioned restraint, implementing this scheme in a underdeveloped state similar to Nigeria will be onerous. This is due to the prevailing norms of unlawful garbage disposal all throughout the state. It will therefore entail equal environmental awareness/education for the populace. More so, rigorous environmental Torahs and ordinances ought to be carried out by all concerned.

2.4.1 Prevention of Waste

Waste bar stays the best signifier of waste direction as a outcome of it’s the most effectual manner of cut downing the sum of waste that’s generated. It is apart from essentially the most environmental friendly means has it has perfectly no consequence on the environment. It reduces air pollution, saves electricity and saves way more vitality than all other companies of waste bar ( Vallero, 2004 ) .

Finkbeiner ( 2003 ) acknowledged that the figure one priority in waste direction ought to be waste bar as it’s the greatest manner to halt the accretion of waste and a decrease of lack of sources. This process ought to be began firstly of manufacturing.

The primary assault of waste bar and decrease is for the makers to redesign and box their merchandises with the lowest toxicity and least volume of stuff. Industrialist and families can besides reduce down their waste by selective buying and recycle of some merchandises and stuffs ( Angell, 1995 ) . It may be stated that waste decrease relies upon mainly on the shoppers and the picks they make. As such manufacturing and fabrication corporations ought to observe cleaner tendencies within the production process. They should apart from seek to encouragement the buyer ‘s decide to back up less uneconomical merchandises and providers ( CEC 2001 ) . This can be achieved via the usage of clean engineering. Their capability to take sustainable merchandises that have the least unfavorable consequence on the setting is the necessary thing to sustainable waste direction ( Spoolman, 2008 ) .

2.4.2 Recovery of Waste/Energy

Recovery is a waste path method whereby the biological, bodily or chemical kernel of a waste merchandise is altered so as to cut down the consequence of such waste on the environment ( Cheremisinoff, 2003 ) Energy can be recovered through assorted agencies ; illustration chemical, thermic, bodily and biological procedures. Some waste path schemes for restoration of power include:

Composting: This is an environmental pleasant manner of diminishing the volume of waste produced and apart from deliver forthing fertiliser ( Bertoldi, 2006 ) . Because of the low negative impression it has on the setting, the European Union has rated this technique of waste disposal actually excessive ( DEFRA, 2006 ) . It is a microbic based aerophilic method that trades with the additions of resource efficiency and creates utile merchandises from waste stuff that could hold in any other case been discarded ( USEPA 2011 ) . The process of composting is peculiarly favoured for utilization in the tropical and sizzling clime states. This is because of the high price of biodegradation in these parts as a consequence of the clime. Harmonizing to Tyler and Scott ( 1999 ) about 70 % of the waste watercourses in growing states are compostable. The basic process of composting is such that the natural ratios of municipal stable wastes is isolated from the inorganic parts and so laid naked to composting, this can be accomplished in a mechanised method using machines and instruments to manage the wastes and modulate the composting circumstances. Composting can besides be semi mechanized in which instance the composting procedure is allowed to happen in fact and less equipment is used. Composting besides removes the organic affair within the waste watercourse thereby bettering the recycling and incineration procedures. Nevertheless, a figure of nursery gases similar to methane, C dioxide and so forth. are launched into the ambiance throughout this procedure, among other things, hence it is apparent that composting has its unfavorable environmental impacts.


Incineration is another methodology of reduce downing municipal solid waste. It basically entails the burning of waste stuffs with the utilization of an incinerator under temperatures of over one thousand Degree Celsius ( Environmental Protection Department, 2005 ) . During the incineration process, strong waste is sorted out on the footing of their combustibleness. Thereafter, the combustible stuffs among the waste are thrown into the incinerator and burnt. Incineration of waste is a extraordinarily effectual methodology of cut downing waste as surveies have shown that it reduces the sum of waste dumped in landfills by up to eighty % volume and weight ( Roberts, 1978 ) . However, this technique is type of capital intensifier and in addition to requires high care price and proficient expertness. This is why it is merely popular among developed states and states corresponding to Nigeria do non readily pattern it ( World Bank, 2002 ) .

Anaerobic soaking up:

Anaerobic digestion is a biochemical process that takes topographic level when there is an build-up of wet natural affair, in the deficiency of dissolved O. Through the motion of anaerobiotic micro-organisms, natural affair is transformed to H2O, methane and new cells. These are so collected and used as gaseous gasoline while the filth settlings are used as dust conditioner. Anaerobic absorbing apart from aids procedures of landfilling by extinguishing gluey organic waste stuffs that are responsible for gaseous and liquid radiations. It is often carried out in shut armored combat vehicles that enable for the aggregation of massive elements of biogas produced ( Keller, 2007 )

Surveies indicate that this process of waste course reduces the complete quantity and weight of waste generated by over 25 % ( Jason, 2009 ) . It is cardinal to make renewable power from biodegradable waste, as a substitute than lending to local weather alteration by way of the release of methane fuel that occurs during landfilling and incineration ( Marek, 2007 ) Harmonizing to EA ( 2001 ) , methane fuel is 20mtimes more potent than CO2 as a nursery fuel. The residue gathered from anaerobiotic soaking up is out there in each liquid and stable signifier. This residue is known as digestate and is used to condition the filth and in addition to as a fertiliser. This byproduct is used widely on farms in states like Germany, Sweden, and Austria. ( Hardtle,2007 ) propounds that roughly zero.forty six % of electrical energy needed within the UK may be generated by way of the anaerobiotic digestion of nutrient waste. Unfortunately, using anaerobiotic soaking up in developing states like Nigeria is actually restricted as a outcome of miss of expertness, engineering and the related substructure.

Landfilling: For landfilling, the solid waste is dumped and spread over the land and is left for its transmutation to humus. This is attained by the biodegradation of the waste affair. Landfilling is the concluding measure within the disposal of waste that can non be treated or recycled, along with other residues from waste that can non be collected, separated or handled in another method ( Nemerow,2007 ) There are three forms of landfill carried out in Africa at present, viz. unfastened or shit landfill, semi managed or operated landfill and healthful landfill. Open /dump landfill is the most rough signifier of landfilling and that is the 1 still being practiced in most underdeveloped states including Nigeria. A healthful landfill is a solid waste path methodology that’s aimed and operated in a mode that protects the environment and public wellness. ( Nemerow, 2007 )

There are some components needed for the structure of a healthful landfill site. These elements include:

Planing and casing the waste spread web site, with waste and dust positioned in tight beds.

Measuring the technology, geological and hydrological traits of the site and besides the environmental impact analysis, tipping program and website Restoration program.

The utilization of line drives to suppress the infiltration of leachate into the dirt to let for full or restricted hydrogeological isolation to take topographic point

The disadvantages of the landfilling process are apart from worthy of reference. Leaching of unsafe substances and foods are more doubtless to occur, if landfilling is non practiced with correct environmental safety ( Bilitewski and Hardtle, 2004 ) . Contamination of groundwater can besides occur in nations round landfill websites and it is a hapless waste course assault. Landfilling should at best, be thought of a impermanent solution to the waste job as it tends to go a large environmental pollutant as clip goes by ( Rosenfeld, 2008 ) . This is so because as quickly as the lifetime of the barrier comes to an terminal, landfill leachates leak out and pollute the land H2O all around that country ( Lee, 2004 ) . In order to prevent such happenings, appropriate statute legislation should implemented and even enforced to guarantee that correct landfill and design are carried out ( Mannan and Jones 1997 ) . The European Union has laid down rigorous calls for for landfills so as to debar and minimize down the negative influences on the surroundings, specifically on surface and land H2O, dust, air, and human wellness ( Jasiski, 2010 )

Figure 2.4.2 Landfill site in Port Harcourt ( starting: Obijiofor, 2009 )

Aside from the above talked about 1s, other waste path rules have been established as possible schemes for work outing Municipal Solid Waste Management points. Rushkin ( 2009 ) provides some of them as:

Making Awareness: This involves the usage of mass media, consciousness runs and every different businesses of sensitising the populace on the effects of foolhardy waste disposal and the environmental benefits of fine waste course.

User Pays Principle: This rule requires that the customers of the sources bear the fiscal value of those who present waste path companies for their endeavor. This discourages uneconomical consumerism.

Polluter Pays Principle: This entails the producers of waste to pay straight for the hurt attributable to their waste. This rule was foremost propounded in 1972 on the behest of the OECD council on Steering Principles refering International Economic Aspects of Environmental Policies. Harmonizing to Trevor ( 2010 ) the rule that is used for assigning costs of pollution arrest and management to guarantee the rational usage of environmental sources is the alleged Polluter-pays-principle

Product Stewardship Principle: It requires the makers or importers of waste to take responsibility of the environmental impacts of their merchandises.

2.5 Waste Composition in Port Harcourt

The challenges of stable waste path in metropoliss of developing states like Nigeria are rather completely different from these in developed western states. Besides, the composing of waste generated is besides dissimilar from state to state depending on the rate of development of that peculiar state, civilization and fee of growth. Depending on the societal category and enterprise of the dwellers of a peculiar country, the kind of waste they produce tremendously varies. Solid waste coevals of 3rd universe states is 0.6 to zero.8kg/person/day, compared to 1.0 to 1.6 kg/person/day in industrialised states ( Zerbock 2003 ) . Ogwueleka ( 2009 ) acknowledge that developing states like Nigeria have dissimilar solid waste course jobs from first universe states. These differences can straightforward be noticed in in nations of density/volume, constellation, and economic model, sum of waste generated, entree to waste for aggregation, consciousness of proper waste disposal methods and attitude of the citizens. ) . A survey by Ajao and Anurigwo ( 2001 ) estimated that 168,201 metric tons of strong waste were produced per twelvemonth in Port Harcourt which is the first country of survey on this. It is, nonetheless, of import to observe that family waste make up for over 60 % of municipal solid waste, in the United Kingdom with kitchen waste being the biggest ( DEFRA 2006 ) . Past analysis and surveies point out that this can be said to be the identical for the metropolis of Port Harcourt. Harmonizing to Mba ( 2004 ) , waste composing in Port Harcourt is basically made up of:

Garbage: This constitutes close to to 70 % of all waste generated in Port Harcourt municipality. Its starting is chiefly the households and concern places of work within the metropolis and it’s chiefly biodegradable. Other waste merchandises generated therein embrace paper, carton/cardboard, plastics, fabric film editings, bottles, ceramics, Sn tins and so forth.

Waste derived from little graduated desk activities such as avenue sweeping, demolition/rubble waste, ashes and so on. It in addition to includes points corresponding to derelict vehicles, carts and bikes littering the streets. However these represent a small per centum of the waste generated. These factors represent a serious waste disposal job within the municipality.

2.6 Municipal Solid Waste Management in Port Harcourt

Nigeria as a state is blessed with ample homo and pure assets. However the advancement and improvement of this nice state has been hindered by hapless municipal solid waste direction strategies ( Adedoyin, 2006 ) . Although Port Harcourt ranks as some of the urbanised metropoliss in Nigeria, it is besides one of the dirtiest ( Alabor, 2007 ) . Driving or walking through the metropolis, the terrible image of cluttered waste is glowering. These waste merchandises are merely dumped on main primary roads and roads representing an eyesore. The crying dumping of solid waste in Port Harcourt and its attendant impact on the environment presently is non apt for healthy life ( Eloho,2006 ) .

The job of municipal stable waste in Port Harcourt may be traced again to over a decennary ago when waste course was the unique duty of the local authorities ( Mba, 2004 ) . An accretion of rubbish builds up in a affair of hours and generally obstructs site visitors. The occupants of Port Harcourt were non adequately serviced by the Local Government Authorities in the facet of waste aggregation and disposal. There have been no public waste bins, no designated shit sites and so on. so the public recklessly dumps their household waste on the route. Improper waste disposal strategies corresponding to unfastened combustion, dumping rubbish along the route or in unfastened Fieldss, within the watercourse or rivers and in landfills were the order of the twenty-four hours ( Olowomeye,2001 ) . This led to immense environmental pollution. To this twenty-four hours, a immense garbage job nonetheless exists in Port Harcourt. Municipal stable waste generated in the metropolis is usually dumped randomly. These illicitly dumped wastes constitute a job for human wellness and the debasement of the setting ( William, 2005 ) . Previous surveies show that the chief composing of municipal solid waste in Port Harcourt is chiefly fictile, paper, natural nutrient waste, metal, cloth, aluminum and glass ( Igoni et al, 2007 ) . These waste stuffs form nearly all of the rubbish which would possibly be discarded randomly in the metropolis.

The authorities offers rubbish bins at designated musca volitanss on the route and streets yet folks merely disregard these and dump their wastes randomly, most times where of all time that proves most convenient for them ( Adedokun, 1992 ) . This waste contaminates ground H2O, serves as a genteelness land for rats, flies and other plagues, and finally leads to the spread of ailments. Besides, indiscriminate waste disposal in the metropolis results in the decrease of available land and the sturdy emanation of methane gasoline contribute to planetary heating and exhaustion of the Earth ‘s pure assets ( Williams, 2005 ) .

The obvious grounds behind the actions of the individuals of Port Harcourt embody: High diploma of illiteracy, deficiency of consciousness about proper disposal strategies and reluctance to collaborate on the difficulty of waste disposal ( Nabegu, 2010 ) . The authorities apart from arrange bureaus and ministries responsible for municipal waste path within the province. These bureaus obtain fiscal and proficient assist from the province environmental price range to efficaciously transport out their responsibilities ( Okot-Uma,2000 )

Harmonizing to Obijiofor, 2009 the Government bureaus formally in charge of stable waste course in Port Harcourt are:

The State Ministry of Environment and Water Resources

Local Government councils and wards ( Environmental Department ) .

Rivers State Environmental Authority ( RSESA ) : This bureau is the chief administration in charge of municipal solid waste aggregation, transportation and disposal. They are in addition to responsible for the enrollment and licensing of personal garbage aggregators in the metropolis, maintaining landfill sites and implementing all laid down ordinances refering garbage aggregation, disposal and sanitation all across the metropolis ( Ekosse,2000 )

The Federal Government of Nigeria created the Decree 58 and established the Federal Environmental Protection bureau. Their authorization was to handle the aggregation and disposal of garbage in Nigerian metropoliss, procure the setting for wellness and wellbeing and due to this fact advance sustainable improvement in the state ( Ogu, 2000 ) . The Federal Government apart from initiated the Environmental Sanitation exercising that is carried out one time a month throughout the state. The objective of such an exercising was mainly to instill a way of environmental consciousness into the heads of the public ( Obefe, 1993 ) . All of these steps, nevertheless, have non helped to perform the chief functions for which they have been instituted. This is due to the lack of those established bureaus to dispatch their responsibilities efficaciously. The province bureaus in control of municipal waste direction, most instances, do non maintain enough authorities support and support to be every bit environment friendly as the personal waste course companies within the disposal of waste ( Christain, 2011 ) . This consequence in exorbitant charges charged by the non-public firms for remotion of waste and as such merely excessive earnings earners can afford their services. The the rest of the common public in that nation that undergo disregard from the province environmental bureau now resorts to dumping their garbage within the unfastened, rivers, brooks, empty secret plans of land and even in drains. This causes deluging most occasions and the waste dumped in drains could also be carried off by run-off H2O into bigger organic buildings of H2O like seas or lakes and fouling them, due to this fact, impacting the ecosystem ( Ankidawa, 2007 )

It is of import to watch that ignorance performs a significant portion within the actions of these perpetrators of indiscriminate waste disposal ( Adeh, 2010 ) . A profound deficiency of cognition about waste direction methods can be noticed among the dwellers of some elements of Port Harcourt. They are merely non cognizant of the environmental and wellness dangers of dangerous waste disposal. This is especially among the many middle/low class neighborhood whose residents can non afford the providers of private waste course corporations. They are so left on the clemency of province run Environmental Protection Agency which is severely funded and badly motivated as it does non have the authorities attending it good deserves ( Igwe, 2000 ) . Solid waste generated in these countries are normally burned exterior within the unfastened by the occupants or dumped by the waysides in huge tonss as there is not a formal waste collection/disposal system put in topographic level by the authorities ( Iheanacho, 2009 )

The informal/local recycling sector in Port Harcourt metropolis in addition to enjoys really small support from the Government and even the personal sector, but they’ve been capable of accomplish some success in recycling municipal solid waste. The basic disposal methods are via the scavengers. These are mainly males between the ages of 14 to 35 with no formal instruction or preparation and as such do non maintain any opportunity of white collar employment ( Ogbonna, 2002 ) . They rummage by way of the waste pile, decide up reclaimable and reclaimable waste and sell them to makers who recycle the waste into correct items. This is a signifier of employment for most individuals that do non hold any businesses of assist ( Obijiofor et al 2009 ) . The reclaimable stuffs like plastics, glass, steel and materials in this tremendous pile of garbage so pull the attending of these local scavengers. They sort out rubbish at the shit sites and so taken to be reused and or recycled. There are one other group involved within the aggregation and transit of rubbish from these countries. They are the local cart thrusters. They acquire and transport these reclaimable stuffs from the houses and nations generated and promote it to the industries as natural stuff that can be utilized for recycling. The cart thrusters, nonetheless, cost a disposal fee from the homes that generate this waste. They make about $ 25 per twenty-four hours ( Ayobolu, 2005 ) .The waste stuffs collected are typically washed and dried out earlier than they’re sold to say no traders both at disposal websites or at debris shops ( Onibokun, 1999 ) ) . In different larger metropoliss, like Lagos, this is a really moneymaking concern due to the copiousness of garbage mopess all throughout the metropolis. The aggregation and transit of the reclaimable waste is really labour intensifier and it is projected that this histories for sixty five % to 70 % of the complete value waste path in the state ( Oluwande, 2008 ) . The main scavenging and recycling done in Nigeria is casual and they’re derived from assorted waste. The reclaimable content of stable waste all throughout the metropolis is said to be roughly 58 % and it is comprised of natural affair which makes it debatable to incinerate. For illustration, glass is processed and recycled locally to offer cullet which can be used for the manufacturing of other issues such as disks, tumblers etc. whereas entire glass bottles are exhaustively washed and cleaned, the reused for re-storing domestically made drinks, medical specialties etc ( Imman et al,2008 ) .

The activities of those scavengers have in addition to, in a way, hindered improvement and gross coevals through the recycling of waste as they find yourself dumping the waste randomly excessively. Irrespective of all that, the identical solid waste job nonetheless persists. This is made more so because even after the scavengers have recovered the reclaimable waste stuffs they need, they find yourself disposing the residuary waste randomly. However if decently managed, the immense sums of waste could be remodeled into commercial, industrial, and household goods thereby bring forthing gross for the authorities and employment for individuals in that sector. ( Ekwezor, 2010 ) .



Previous environmental incidents which have occurred highlighted the demand for the passage, growth and alteration of environmental safety laws/legislation on waste disposal all over the universe ( Odibo, 2009 ) . The leaking of PCBs into rice Fieldss in Osaka, Japan in 1968 ; the methane gasoline detonation in the USA in 1969 and the nitrile dumping episode in Coventry, Warwickshire, UK in 1972 are a few of the incidents that have raised planetary concern on the demand to hold standing Torahs and ordinances steering the problems of waste course amongst all states of the universe ( Mckenzie, 2008 ) . This prompted the UK waste direction bureau to take essential actions to modulate municipal solid waste disposal so as to prevent future occurring ( Williams, 2005 ) . Before these incidents, actually small concern was proven in the direction of establishing ordinances for solid waste disposal strategies such as landfills and as such, it had a annihilating consequence on the setting ( Sarsby, 2000 ) .

However, at a peculiar clip, a gradual flow of directives from the European Union was issued with the purpose of training and organizing waste direction schemes and policies throughout Europe ( DOE, 2005 ) . The declaration of waste regulations/legislation was to efficaciously pull off waste and environmental assets available. Surveies indicated that a batch of states including the UK established ordinances which made it obligatory that non-hazardous waste websites be transformed into healthful landfills so as to halt the flight of leachate from the landfill websites into the environing evidences or H2O natural constructions ( Bagchi, 2004 ) . Furthermore, incidents of waste disposal just like the nitrile dumping in Coventry and the detonation in the US caused so much public name.

In 1972 the United Kingdom joined the EU group and later implemented the Control of Pollution Act of 1974. This was the first legislative act that structured the disposal of waste to land and the discharge of wastewater to sewer and H2O classs ( Hawkins and Shaw, 2010 ) . After being a signer to the EC, the first legislative act modulating the disposal of waste to land and the discharge of wastewaters into waterways and sewerages was adopted by the UK. ( Hawkins and Shaw, 2000 ) . That act is recognized as The Control of Pollution Act 1974 ( COPA 1974 ) . The ultimate goal is to guard and better the value of the setting ( Odibo, 2009 ) The ECAs a direct consequence of the Control of Pollution Act of 1974, the European 75/442 Waste Framework Directive was created. As amended by the 91/156 Directive, it states that ‘Disposal includes the aggregation, classification, passenger automotive, intervention and stowage of waste pending tipping above land or incineration ‘ . To efficaciously implement the 75/442 Directive, the UK established some other statute legislation in subsequent old ages and it led to the debut of the Environmental Protection Act of 1990 ( EPA 1990 ) . This Environmental Protection Act of 1990 contained a scope of subjects for the protection of the setting and Part II of the EPA Act changed and reinforced the waste disposal Framework in COPA 1974. The Waste Framework Directive besides makes it compulsory for all animal trainers of waste ; including those involved in storing, transit, intervention, and disposal to maintain a waste path licence. This license should be issued out by the Environmental Agency totally, unless they’re excluded by the next authorization. The Environmental bureau hence has the responsibility of publishing out licenses, supervising for conformity amongst license holders. The inventive exercise of the Environmental Protection Act of1990 was introduced approximately by the debut of recent statute legislation for the effectual execution of the waste Framework Directive by the UK. This Act included a choice of topics for the safety of the surroundings and portion 2 of the Act supplanted and efficaciously bolstered the waste disposal mannequin in COPA 1974 ( Odibo, 2009 )

In add-on, the United Kingdom adopted statute legislation throughout the European Union that regulates waste path. This peculiar legislative act is the statute regulation on waste intervention operations. To expeditiously implement the ordinances on waste intervention operations, the EC divided its operations into three Directives viz. :

The Integrated Pollution Prevention and Control Directive 1996 ( 96/61/EC ) : This policy was developed within the UK so as to advance development by selling environmentally friendly economic activities. The Directing purposes at efficaciously forestalling waste through ‘clean ‘ and improved engineering. It was further developed into the assemble of a ‘waste direction hierarchy ‘ which structures the full procedure of waste path from bar, reuse and recycling to optimization of the concluding disposal technique ( DoE, 1995 )

The Landfill Directive ( 1999/31/EC ) : The Landfill Directive got here into being throughout the European Union on the sixteenth of July, 1999 with the aim of complementing controls on landfill websites all across the EU. Its chief aim is to chop down pollution like methane gas emitted in landfill sites and apart from emphasizes on common criterions for the design, operation and the after consideration of landfill websites. This statute regulation was tailor-made to higher the final criterion of landfilling throughout Europe. The dictates of the Landfill Directive are executed via the Landfill Regulations 2002 for England and Wales ( Bagchi, 2004 ) . It encompasses all the inside informations concerning the designing, kind of waste most suited to a peculiar landfill, operation and post-operative attention of all the landfills in EU member provinces ( Williams, 2002 ) .

The Directive on the Incineration of Waste 2000 ( 2000/76/EC ) : This statute regulation regulates and proctors conformity for correct incineration of procedures of waste all through the European Union. The purposes and aims of waste incineration directive are to restrict or forestall, every bit far as operable, the unfavorable impacts of waste on our surroundings. Contamination of groundwater, dust and even the air by emanations given off during waste incineration, are some of its chief factors of focus. The Directive apart from involves the scene and care of rigorous operational conditions and proficient calls for for incinerating workss throughout the EC to have the ability to to the full shield the setting and the individuals populating in it. ( DEFRA, 2009 )

To guarantee that the Directives are efficiently carried out in the UK, the strategic planning and readying was accomplished by the Environmental bureaus Local authoritiess, native planning authorization and all local industries ( Williams, 2005 ) . The Local and Federal Government, Environmental Agency, Local planning governments and the overall populace have besides been merged into take parting in all these waste path guidelines talked about above ( Odibo 2009 ) . The UK aimed to journey up the waste path hierarchy process. In add-on, the waste direction strategy within the UK involved and encouraged public engagement. An illustration of this was the planning permission for an industrial mixed warmth and power web site in South East London following public agitation and engagement ( ISWA 2000 ) .

To additional implement these Directives and Acts, the undermentioned guidelines have been based mostly on it ( Dubois, Gonzalez and Knadel 2004 ) :

Principle of propinquity: This rule requires that waste be handled each bit close to as possible to its level of coevals, manufacturing or aggregation.

Best Operable Environmental Option: This is a methodical option or appraisal of all available waste intervention or path options so as to place the best 1 that will vouch maximal environmental, financial, and societal advantages ( DOE, 2005 )

Waste Management Hierarchy: This entails the bar, recovery re-use and recycling of pure stuffs from strong waste.

Polluter Pays Principle: This stipulates that defilers are financially responsible for their waste and as such, waste disposal installations have to be paid for by the defilers themselves and non from the revenue enhancement remunerator ‘s financess.

Principle of Self Sufficiency: This requires that every member province of the pact is mainly liable for its ain generated waste and ought to be held accountable for it always.

Principle of Best Available Technology ( BAT ) : This rule requires that waste disposal installations be outfitted with one of the best available engineering designed with the setting in head.

In add-on to those, the Waste Framework besides makes it obligatory for all people who transport, shop, dainty and dispose all waste stuffs to keep a waste path licence that should be issued by the Environmental Agency. All these go to demo that since the Eighties, the European Union have endeavoured to realize sustainable development via encompassing all signifiers of societal, economic and environmental dimensions of sustainability ( Kit and Strange 2002 ) .



Nigeria is probably the most populated state on the African continent. It occupies about 14 % of the land mass in Africa, and has a population of over 166 million folks. It is between Latitudes 4`N and 14`n of the Equator ; with Cameroon surrounding on the East, Niger democracy and Benin Republic flanking on the West and North severally ( Federal Ministry of Environment, 2001 ) . Nigeria has a whole length of about 850km of Atlantic Ocean boundary and a whole floor country of about 923,773 square kilometers ( Adeyinka, Bankole and Solomon, 2003 ) . Port Harcourt, which is the capital of Rivers State, is situated in the southern portion of Nigeria. It is a giant port town with an estimated inhabitants of 1,382,592 ( NPC, 2006 ) . Port Harcourt lies along the bonny river, 41miles ( 66km ) upstream from the Gulf of Guinea. It has a average one-year rainfall of 2280mm and an imply one-year lower restrict and maximal temperatures of 24.three grade centigrade and 35.1 grade centigrade severally. The conditions is identical as the rest of the state, tropical and its driest months commence from December to March with dust type that consists mainly of silt clay assorted with sand ( Ayotamuno et al, 2006 ) .

Port Harcourt, the capital of Rivers province, is the Centre of Nigeria ‘s oil business and is extremely industrialised. Owing to the discover of oil within the 50 ‘s in the Niger Delta half, the country has continued to bask all some great advantages of urbanisation boulder clay day of the month. It is in addition to the largest base of transnational oil operations in the state. The oil roar led to a fast influx of migrators in hunt of occupation chances, thereby giving rise to over population ( See map of Port Harcourt under ) . However, inhabitants growing via rural to city migration was non limited to Port Harcourt completely as most metropoliss in addition to witnessed an inflow of people from the agricultural countries, hence an addition in the sum of municipal strong waste generated ( Odubela, 1998 ) . The lifting quantity of waste produced over the old ages has led to projections and value determinations by environmental bureaus in a command to have the ability to expeditiously map out schemes to tug off municipal strong waste.

In 1987, a giant measure of poisonous waste was dumped in slightly town referred to as Koko in Bendel province. This sparked off widespread illness, infections and decease within the nation, distributing panic throughout the state. Consequently, the Nigerian Government propagated the Harmful Waste Decree which provided the authorized mannequin for the operational management of the coevals and disposal of all kinds waste in within Nigeria. After this in 1988, the regulative organic structure, the Federal Environmental protection bureau ( FEPA ) was established. It was bestowed with the responsibility of guarding and creating the Nigerian surroundings ( Echefu and Akpofure, 2010 ) . The legal mannequin for environmental policies in Nigeria originates from the Nigerian Constitution. It stands as the inspiration on which all of the Environmental Protection Acts are based mostly upon. The fundamental regulation of the Federal Republic of Nigeria 1999 in Section 20 provinces that “ the State shall always protect and better the surroundings and safeguard the H2O, air and land, wood and wildlife of Nigeria ” ( International Centre for Nigerian Law 2009 ) . Based on that, the authorized constitution for environmental safety in Nigeria comprises of the followers ( Atsegbua, 2004 ) :

National Policy on Environment, Act forty two of 1988: This act deems 9it a condemnable offense to import or merchandise in poisonous waste in Nigeria. It was promulgated with the purpose of undertaking sustainable development ( Adeh, 1991 )

Harmful Waste Act of 1988.

National Environmental Regulations and Pollution Abatement 1991: this was enacted to cut down and supervise the coevals of business waste in Nigeria.

The National Guidelines and Standards for Environmental Pollution Control in Nigeria ( Regulation S.1.15 ) : This is apart from for the overseeing of solid and risky waste.

Environmental Impact Assessment Act of 1992: This is to safeguard the setting and do certain that private and public sector firms or individuals do non ship on or empower activities or undertakings with out anterior deliberation of the impression of those actions to the surroundings.

2.8.1 Institutional Framework

The Federal Government, by the commissariats of the fundamental law, created the Federal Environmental Protection Agency Act of 1988 ( FEPA Act ) . This Act led to the structure of the Federal Environmental Protection Agency in 1992. This organic construction was given the obligation of commanding the environment and apart from growing policies and processs that may help maintain the environment ( Akpotaire and Folarin, 2011 ) . It operates a cardinal administrative system with central places of work situated on the Federal Capital Territory, Abuja and Zonal workplaces located in Lagos, Port Harcourt, Benin-city, Kaduna and Kano. Each zone workplace is charged with flip toing all of the environmental jobs of the provinces within their zones. Harmonizing to subdivision 4 of Decree fifty eight, the Federal Environmental Agency was instituted to move out the followers:

Liaise with the Federal and State ministries, native authorities councils and research bureaus on overlaying with affairs associating to environmental safety.

Prepare and present programs for the event of recent methods and patterns of environmental course.

Advice the Government and sensitise the public new environmental issues and policies every time the demand arises.

The Environmental Guidelines and Standards for the Petroleum Industry in Nigeria ( EGASPIN ) 2002: This was issued by the Department of Petroleum Resources ( DPR ) , harmonizing to ( Aluko and Oyebode, 2006 ) , with the responsibility of transporting out regular wellness and environmental value determinations and reapp
