Leave a comment

Nigeria, the most populous country in Africa with population exceeding 182 million people, is grappling with waste management issues. The country generates around 43.2 million tonnes of waste annually. By 2025 with a population of 233.5 million, Nigeria will be generating an estimated 72.46 million tonnes of waste annually at a projected rate of 0.85 kg of waste/capita/day. This means that Nigeria annual waste generation will almost equal its crude oil production which currently stands at approximately 89.63 million tonnes per year.

Also, at an estimated annual waste generation figure of 72.46 million tonnes, Nigeria will be generating about one-fourth of the total waste that will be produced in the whole of Africa. This is scary and if proper attention is not paid to this enormous challenge, Nigeria might become the “Waste Capital of Africa”.

Waste is a Resource for Nigeria

Nonetheless, this challenge can be turned into a blessing because waste is a resource in disguise. If its potential is properly tapped, waste management can create employment, enable power generation, create a waste-based economy and contribute to economic diversification which Nigeria. There is no doubt that this is achievable because we have examples of countries already utilizing their waste judiciously.

Some good examples of sustainable waste management systems that can be implemented in Nigeria includes

  1. Shanghai (China) which turn 50% of the generated waste into power generation electrifying 100,000 homes;
  2. Incheon (South Korea) where its Sudokwon landfill receives about 20,000 tons of waste daily which is converted into electric power, has a water recycling and desalination facility, and has created more than 200 jobs;
  3. Los Angeles (USA) which produces electric power enough for 70,000 homes in its Puente Hills landfill;
  4. Germany whose sophisticated waste processing systems through recycling, composting, and energy generation has already saved the country 20% of the cost of metals and 3% of the cost of energy imports;
  5. Austria, though a small country, is doing big things in waste management especially through recycling;
  6. Sweden, whose recycling is so revolutionary that the country had to import waste; and
  7. Flanders, Belgium which possesses the best waste diversion rate in Europe with 75% of their waste being reused, recycled or composted. An interesting fact is that per capita waste generation rate in Flanders is more than twice that of Nigeria at 1.5 kg/day.

Waste Management Outlook for Nigeria

Below are some of the major things the government need to do to judiciously utilize the free and abundant resource available in the form of trash in Nigeria:

Firstly, attention needs to be paid to building the human resource potential of the country to build the required capacity in conceptualizing fit-for-purpose innovative solution to be deployed in tackling and solving the waste challenge.

While knowledge exchange/transfer through international public private partnership is a possible way in providing waste management solution, it is not sustainable for the country especially because there is already an unemployment problem in Nigeria. Hence, funding the training of interested and passionate individuals and entrepreneurs in waste management is a better way of tackling the waste crisis in Nigeria.

The Federal Government through the Petroleum Trust Development Fund (PTDF) and National Information Technology Development Agency (NITDA) of the Ministry of Communication currently sponsor students to study oil and gas as well as information technology related subjects in foreign countries in the hope of boosting manpower in both sectors of the economy. The same approach should be used in the waste management sector and this can be handled through the Federal Ministry of Environment.

Interestingly, waste generation is almost at par with crude oil production in Nigeria. Therefore, equal attention should be paid to waste-to-wealth sector. Needless to say, this is important as there is no university in Nigeria currently offering waste management as a stand-alone course either at undergraduate or postgraduate level.

The Rationale for National Waste Strategy

Secondly, there is an urgent need for a strong National Waste Management Strategy to checkmate the different types of waste that enters the country’s waste stream as well as the quantity of waste being produced. To develop an effective national waste strategy, a study should be carried out to understand the country’s current stream of waste, generation pattern, and existing management approach. This should be championed by the Federal Ministry of Environment in conjunction with State and Local Government waste management authorities.

Once this is done, each State of the Federation will now integrate their own individual State Waste Management Plan into that of the Federal Government to achieve a holistic waste management development in Nigeria. By so doing, the government would also contribute to climate change mitigation because the methane produced when waste degrades is 25 times more potent than carbon dioxide (a major greenhouse gas known to many and contributor to global warming).

The Need for Financial Incentives

Finally, the government needs to support existing waste management initiatives either through tax-holiday on major equipment that need to be imported for their work and/or on their operation for a certain period of time. Also, if workable, the government can float a grant for innovative ideas and provide liberal subsidies in waste management to jumpstart the growth of the sector.

Lastly, the Government of Nigeria can raise a delegation of experts, entrepreneurs, industry professionals, academia, and youngsters to visit countries with sound waste management strategy for knowledge sharing, capacity-building, technology transfer and first-hand experience.

A Glance at Biggest Dumpsites in Nigeria

  By | | , ,
17 Comments

Waste dumping is the predominant method for solid waste disposal in developing countries worldwide, and Nigeria is no exception. Nigeria is home to six of the biggest dumpsites in Africa, according to Waste Atlas 2014 report on World’s 50 Biggest Dumpsites published by D-Waste. These dumpsites are located in three most important cities in Nigeria namely, Lagos, Port Harcourt and Ibadan.

Let us have a quick look at the major landfills in Nigeria:

Olusosun

Olusosun is the largest dumpsite not only in Lagos but in Nigeria and receives about 2.1 million tonnes of waste annually comprising mostly of municipal solid waste, construction waste, and electronic waste (e-waste). The dumpsite covers an area of about 43 hectares and it is 18 meters deep.

The dumpsite has been in existence since 1992 and has housed about 24.5 million tonnes of waste since then. A population of about 5 million people lives around 10km radius from the site and numerous health problems like skin irritation, dysentery, water-related diseases, nausea etc. have been reported by residents living around 3km radius from the site.

Solous 2

It is located in Lagos and occupies around 8 hectares of land along Lasu-Iba road. The dumpsite receives about 820,000 tonnes of waste annually and has since its existence in 2006 accepted around 5.8 million tonnes of MSW.

Solous is just 200 meters away from the nearest dwellings and almost 4 million people live within 10km radius from the site. Due to the vulnerable sand formation of the area, leachate produced at the dumpsite flows into groundwater causing its contamination.

Epe

Epe dumpsite also in Lagos occupies about 80 hectares of land. The dumpsite was opened in 2010 and has an annual input of 12,000 tonnes of MSW. Epe is the dumpsite which the Lagos State government is planning to upgrade to an engineered landfill and set to replace Olusosun dumpsite after its closure.

Since its existence, it has received about 47,000 tonnes of waste and it is just 500 meters away from the nearest settlement. The dumpsite is also just 2km away from Osogbo River and 7km away from Lekki Lagoon.

Awotan (Apete)

The dumpsite is located in Ibadan and has been in existence since 1998 receiving 36,000 tonnes of MSW annually. It covers an area of 14 hectares and already has in place almost 525,000 tonnes of waste.

The dumpsite is close to Eleyele Lake (2.5km away) and IITA Forest Reserve (4.5km away). The nearest settlement to the dumpsite is just 200 meters away and groundwater contamination has been reported by nearby residents.

Lapite

Lapite dumpsite is also located in Ibadan occupies an area of 20 hectares receiving around 9,000 tonnes of MSW yearly. Since its existence in 1998, it has housed almost 137,000 tonnes of MSW. It is 9km away from IITA Forest Reserve and surrounded by vegetations on both sides of the road since the dumpsite is directly opposite a major road.

Olusosun is the largest dumpsite in Nigeria

The nearest settlement is about 2km away but due to the heavy metals present in the leachate produced in the waste dump, its leakage poses a great threat to groundwater and biodiversity in the area.

Eneka

It is located in Port Harcourt, the commercial hub of South-South, Nigeria along Igwuruta/Eneka road and 9km from Okpoka River and Otamiri River. It receives around 45,600 tonnes of MSW annually and already has about 12 million tonnes of waste in place.

The site lies in an area of 5 hectares and it is flooded almost all year round as rainfall in the area exceeds 2,500mm per annum. Due to this and the resultant flow of the flood which would have mixed with dumpsite leachate; groundwater, surface water, and soil contamination affect the 1.2 million people living around 10km radius from the site as the nearest building is just 200 meters away.

Financing of Solid Waste Management Projects

Financing of solid waste management projects can be pretty overwhelming for the city government, especially if the government see it as a critical part of the service they should render to the citizen and if the citizen also hold it as a basis for measuring the performance of the government and using it as one of the conditions for re-election.

The increasing cost of waste disposal is a cause of major concern in developing nations

Solid waste management entails different aspects. Generally speaking, waste management consists of pre-collection, collection, transportation, storage, treatment, and disposal. The modern hierarchy of waste management includes prevention, minimization, reuse, recycling, energy recovery, and disposal.

All these aspects require proper funding in rendering a good waste management service to the society. As citizens, we hardly give any thought to the different aspects and what it takes to ensure it is carried out efficiently and effectively.

Financing Options for Solid Waste Management

There are four different options for financing of solid waste management projects. The option chosen will be dependent on various factors. The chief factor will be “what is the end goal of providing waste management service to citizen” and this is to be determined by the city government. Therefore, we say finance option is directly related to waste management goal of a city or State.

Public Financing

This primarily involves funding of waste management service entirely by the government through budgetary allocation. The government determines how it will generate the cash for service and this can be through taxation or redistribution of funds generated from other sources like sales of city natural resources or combination of various sources of funds.

In developing countries, this is generally inefficient due to the corruption within the government and lack of proper waste management capabilities in most instances. The government might decide to charge a service fee or not.

Private Financing

This involves infusing funds from the private sector into waste management service and also overseeing day-to-day running of the service. However, the hired company will charge a service fee which will be determined by calculating the amount of invested funds, operating cost, and profit envisaged. This will be spread over a period of time.

This financing option can deliver optimal result in providing waste management service but the private sector needs to be checked in order not to set a high fee that will end up scaring citizens which might lead to citizen abhorring the service.

Public-Private Partnership (PPP)

This is a special type of arrangement which brings together the government and private sector in providing funds and management capabilities for the delivery of waste management service.

All things being equal, this arrangement is best because the government will be able to regulate and have a say in how the service should be delivered especially as it relates to the setting of service fees which might be difficult in the solely private financing option. The PPP can equally be extended to be a Joint Venture (usually termed as Institutional PPP).

Recycling trash adds value to the community’s economy and allows those in need of money to find new work. If you need money quickly, banks, credit unions, and reputable lenders like PaydayChampion are common options.

Donors and Grants

This funding mechanism is dependent on the interest of the donor organization. While it is a good way to develop a city’s waste management infrastructure, attracting and utilizing grants is solely reliant on what the donor considers as important. Hence, it might be difficult for a city government to dictate how the funds should be distributed among the various aspect of waste management.

Waste management projects based on public-private partnership (PPP) model has more chances of success in developing countries

However, this type of financing can be combined with a PPP arrangement to cater for a specific waste management aspect that is in tandem with the interest of the donor and can be part of the city government contribution to the PPP.

Conclusion

In conclusion, waste management financing is quite dynamic just like many other services and infrastructure provided by a city government and the best option for financing the provision of waste management service can only be made after appropriate due diligence and consultation with relevant stakeholders has been made and observed.

Waste Disposal Methods: Perspectives for Africa

  By | | , ,

Waste disposal methods vary from city to city, state to state and region to region. It equally depends on the kind and type of waste generated. In determining the disposal method that a city or nation should adopt, some factors like type, kind, quantity, frequency, and forms of waste need to be considered.

For the purpose of this article, we will look at the three common waste disposal methods in Africa and the kind of waste they accept.

Open Dumping/Burning

This is the crudest means of disposing of waste and it is mostly practiced in rural areas, semi-urban settlements, and undeveloped urban areas. For open dumping or open burning, every type and form of waste (including household waste, hazardous wastes, tires, batteries, chemicals) is dumped in an open area within a community or outside different homes in a community and same being set on fire after a number of days or when the waste generator or community feels it should be burnt.

There is no gainsaying that the negative health and environmental impact of such practice are huge only if the propagators know better.

Controlled Dumping

This is apparent in most States in Nigeria, if not all and some cities in Africa like Mozambique, Ghana, Kenya, Cameroon, to mention but a few. It is a method of disposing of all kinds of waste in a designated area of land by waste collectors and it is usually controlled by the State or City Government.

Controlled dumps are commonly found in urban areas and because they are managed by the government, some dumps do have certain features of a landfill like tenure of usage, basic record keeping, waste covering, etc. Many cities in Nigeria confuse the practice of controlled dumping as landfilling but this not so because a landfill involves engineering design, planning, and operation.

Sanitary Landfill

A sanitary landfill is arguably the most desired waste management option in reducing or eliminating public health hazards and environmental pollution. The landfill is the final disposal site for all forms and types of waste after the recyclable materials must have been separated for other usages and other biodegradables have been extracted from the waste for use as compost, heat, or energy; or after incineration. These extractions can be done at household level or Material Recovery Facilities (MRFs) operated by the government or private individuals.

As desirable as a landfill is, so many factors need to be put into consideration in its siting and operation plus it requires a huge investment in construction and operation. Some of these factors include but not limited to distance from the residential area, proximity to water bodies, water-table level of the area the landfill is to be sited, earth material availability, and access road.
