Waste Management Outlook for Nigeria

  By | | , ,
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.

Olusosun is the largest dumpsite 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.

Solid Waste Management in South Asia: Key Lessons

  By | | ,
6 Comments

Solid waste management is already a significant concern for municipal governments across South Asia. It constitutes one of their largest costs and the problem is growing year on year as urban populations swell. As with all waste management experiences, we have learned lessons and can see scope for improvement.

swm-south-asia

Collection and Transportation

There are two factors which have a significant impact on the costs and viability of a waste management system as it relates to collection and transportation: first, the distance travelled between collection and disposal point; and second, the extent to which ‘wet’ kitchen waste can be kept separate from dry waste much of which can be recycled. Separating waste in this way reduces the costs of manual sorting later on, and increases the prices for recyclable materials.

In many larger towns distances become too great for door-to-door collectors to dispose waste directly at the dump site. Arrangements are made to dispose of waste at secondary storage points (large skips) provided by the municipality. However, where these are not regularly emptied, the waste is likely to be spread beyond the bins, creating a further environmental hazard.

Ideally, and if suitable land can be found, a number of smaller waste disposal sites located around a town would eliminate this problem. With significant public awareness efforts on our part, and continual daily reminders to home-owners, we were able to raise the rate of household separation to about 60%, but once these reminders became less frequent, the rate dropped rapidly back to around 25%. The problem is compounded in larger cities by the unavailability of separated secondary storage bins, so everything is mixed up again at this point anyway, despite the best efforts of householders.

If rates are to be sustained, it requires continual and on-going promotion in the long term. The cost of this has to be weighed against the financial benefit of cleaner separated waste and reduced sorting costs. Our experience in Sri Lanka shows how important a role the Local Authority can play in continuing to promote good solid waste management practices at the household level.

Home Composting

Our experience with home composting shows that complete coverage, with every household using the system, is very unlikely to be achieved. Where we have promoted it heavily and in co-operation with the Local Authority we have found the sustained use of about 65% of the bins. Even this level of coverage, however, can have an important impact on waste volumes needing to be collected and disposed of. At the same time it can provide important, organic inputs to home gardening, providing a more varied and nutritious diet for poor householders.

Waste to Compost and Waste to Energy

The variety of technologies we have demonstrated have different advantages and disadvantages. For some, maintenance is more complicated and there can be issues of clogging. For the dry-fermentation chambers, there is a need for a regular supply of fresh waste that has not already decomposed. For other systems requiring water, quite large amounts may be needed. All of these technical challenges can be overcome with good operation and maintenance practices, but need to be factored in when choosing the appropriate technology for a given location.

The major challenge for compost production has been to secure regular sales. The market for compost is seasonal, and this creates an irregular cash flow that needs to be factored in to the business model. In Bangladesh, a significant barrier has been the need for the product to be officially licensed. The requirements for product quality are exacting in order to ensure farmers are buying a product they can trust.

However, the need for on-site testing facilities may be too prescriptive, creating a barrier for smaller-scale operations of this sort. Possibly a second tier of license could be created for compost from waste which would allow sales more easily but with lower levels of guarantees for farmers.

Safe Food Production and Consumption

Community people highly welcomed the concept of safe food using organic waste generated compost. In Sri Lanka, women been practicing vertical gardening which meeting the daily consumption needs became source of extra income for the family.

Female organic fertilizer entrepreneurs in Bangladesh are growing seasonal vegetables and fruits with compost and harvesting more quality products. They sell these products with higher price in local and regional markets as this is still a niche market in the country. The safe food producers require financial and regulatory support from the government and relevant agencies on certification and quality control to raise and sustain market demand.

Conclusion

Solid waste management is an area that has not received the attention it deserves from policy-makers in South Asia nations. There are signs this may change, with its inclusion in the SDGs and in many INDCs which are the basis of the Paris Climate Agreement. If we are to meet the challenge, we will need new approaches to partnerships, and the adoption of different kinds of systems and technologies. This will require greater awareness and capacity building at the Local Authority level. If national climate or SDG targets are to be met, they will need to be localised through municipalities. Greater knowledge sharing at national and regional levels through municipal associations, regional bodies such as SAARC and regional local authority associations such as Citynet, will be an important part of this.

Practical Action’s key messages for regional and national policy makers, based on our experience in the region in the last 5 years, are about the need for:

  • creating new partnerships for waste collection with NGOs and the informal sector,
  • considering more decentralised approaches to processing and treatment, and
  • recognising the exciting potential for viable technologies for generating more value from waste

Entrepreneurship in Solid Waste Management

Entrepreneurship in solid waste management can be instrumental in environment protection, decentralization, economic restructuring and job creation. Entrepreneurial opportunities in solid waste planning are available in the areas of waste collection, handling, sorting, storage, transport, transformation and energy recovery.

Entrepreneurship begins with the generation of an idea and culminates in realization of the project objectives. Historically, the improvement of waste management services by the public sector has been hampered by lack of funds in both developed and developing nations.

Basic safety equipment is essential to minimize health risks to informal recycling sector.

Entrepreneurs can not only invest money in solid waste management sector, but also infuse new ideas, technologies and skills which can transform waste from being a liability into an asset. The efficiency of solid waste management increases with the involvement of entrepreneurs. Infact, it has been observed that involvement of entrepreneurs in solid waste management planning can reduce the service cost by half in Latin American cities with higher employment generation and vehicles productivity.

Entrepreneurial ventures in solid waste management can range from a one-man project to a mega-scale project involving thousands of skilled and unskilled workers. It has been observed that solid waste management is a labour-intensive process with tremendous potential to generate new jobs, depending on the type of project and the level of creativity. The major areas of entrepreneurial involvement include waste collection, transportation, reuse and recycling, upcycling and power generation.

Basic safety equipment is essential to minimize health risks to informal recycling sector.

According to the World Bank, municipalities in developing countries typically spend 20 to 50 per cent of their annual budget on solid waste management, but only 40 to 70 per cent of solid waste is collected and less than 50 per cent of the population has access to municipal waste collection services. Solid waste planning is an integral component of urban development as it contributes to public health, resource conservation and environment protection. Scientific disposal of domestic waste can prevent environmental degradation and harmful public health impacts while recycling can help in conservation of precious natural resources.

Entrepreneurial activities in solid waste collection can not only increase waste collection efficiency but also improve waste management services for the marginalized sections of the society. An excellent example is the case of Nigeria-based Wecyclers which is aiming to building a low-cost waste collection infrastructure in Lagos by offering cheap and convenient domestic waste recycling services using a fleet of cargo bikes.

Peeping into the Future of Waste

Waste management is an important tool for curbing climate change and for keeping our environment clean and healthy. Methane generated from biodegradable wastes is a powerful greenhouse gas, and when it’s not captured and used as a fuel it contributes to rapid warming of the atmosphere. Estimates suggest that biodegradable waste in dump sites and uncapped landfill sites are contributing far more methane to the atmosphere than previously thought. What’s more, urban food waste is predicted to increase by 44% from 2005 to 2025, and with no proper management in place, will significantly add to global greenhouse gas emissions.

Worryingly, 38 of the world’s 50 largest dumps are close to the sea, contributing to marine and coastal pollution. The accumulation of plastics in the marine food chain is causing global concern. While we don’t yet know how to clean the oceans, stemming the flow of waste into marine environments would be a step in the right direction.

Wasted health

40% of the world’s waste ends up in open dumps. These aren’t even what you’d call “landfill”. They don’t have any impervious lining to prevent noxious leachate from entering the surrounding environment, nor are they capped to prevent the spread of disease. In fact, in India, the Philippines and Indonesia, the health risk from open dumping of waste is greater than the risk of malaria[i].

3.5 billion people in the world lack access to proper waste management. That figure is expected to grow to 5 billion by 2050. Respiratory diseases, gastrointestinal diseases and occupational health risks add to the misery experienced by the 50,000+ people living from open dumps.

Waste is any material that is no longer wanted for its original purpose. The owner doesn’t have a need for it, and so discards it. Even valuable items can and do end up as waste purely because someone has thrown them away. The recent (and rather brilliant) BBC programme Hugh’s War on Waste shone the spotlight on attitudes towards disposable fashion. A look through the bins of a typical street uncovered a startling amount of clothing that had been thrown away, despite it still being in perfectly good condition. This highlights a simple fact: there is plenty of value in waste.

  • Estimates suggest there are 40 million people globally who are making their living from waste – half of these are working informally.
  • During the last recession in the UK, the waste management sector was one of the only industries to keep growing, resulting in it being termed the “Green Star of the Economy”.
  • Showing people how to turn a waste stream into something valuable isn’t rocket science. There are lots of examples of informal, community-based, grassroots recycling and upcycling projects that generate wealth for the poorest in society.
  • Internet is allowing simple waste processing techniques to be replicated all over the world, and helping make that information accessible is one of the most fulfilling aspects of my career.

Business skills

“Give a man a fish and he can eat for a day. Show a man how to fish and he can eat for the rest of his life.” Teaching people how to make valuable products from waste is important. But just as important, is passing on the business skills to be able to identify a market, factor in costs, check out the competition, market their products and run a successful business.

Development work in the waste arena needs to address both sides of the coin, and in doing so will enable people to start up their own businesses, in their own communities, and generate wealth organically. That’s far more valuable than delivering aid in a ready-made package (which incidentally rarely works – there’s a great TED Talk on this topic by Ernesto Sirolli, called “Want to help someone? Shut up and listen”).

Why closing dumps isn’t a silver bullet

The proliferation of megacities, particularly in developing countries, is causing a health crisis. Decent waste management is an indicator of good governance – that is, if a council or government can collect taxes and provide a waste management service, then it most likely isn’t (very) corrupt. However, in many places where corruption or other forms of bad or weak governance prevail, top-down solutions are notoriously difficult to implement.

Often, when the world’s attention turns to an open dump, the government responds by closing it and the journalists go home. This is what happened with Smokey Mountain dumpsite in the Philippines (and many others around the world). All that happens is another open dump emerges nearby, and the scavengers move to the new site.

The problem is that if there is no alternative solution in place, people will discard of their waste in the only ways available – dumping it or burning it; and the poor will follow the waste.

Replacing an open dump with a government-controlled waste management system isn’t a silver bullet either. The losers, again, are the hundreds, and sometimes thousands of men, women and children who live from scavenging from the dump. It may seem horrific to many of us, but the truth is that if you take that opportunity to earn a paltry living away from the poorest in society, they will starve. Solutions need to be inclusive.

Power to the people

To close dump sites, you need to have a workable alternative solution in place. You need to have regular waste collection taking place, and you need somewhere to take it. Building materials recovery facilities alongside existing open dumps is one idea. Informal waste pickers who are currently working in dangerous conditions on the dumpsite can gain employment (or better still, form a cooperative) sorting recyclable materials and reducing the amount of real “waste” that needs to be disposed of.

For example, Wecyclers in Lagos, Nigeria employs people to cycle around collecting recyclable materials from households. In return for their source-separated waste, the householder receives a small reward.

In Bangalore, IGotGarbage has harnessed the power of phone apps to enable people who were previously waste pickers to be called directly to a house to collect the waste materials. Solutions like this work because they continue to provide livelihoods for people, while taking waste off the streets.

The need for appropriate technology

There will always be something left though: the stuff that really has little value other than the energy embodied in it. In industrialised countries, energy-from-waste incinerators have become popular. Seen as a clean alternative to landfill, these facilities burn the waste, release the energy, and convert it into heat, electricity and ash. Some of that ash (from the air pollution control system) still needs to be disposed of in specially-prepared hazardous waste landfill sites. The remainder, being fairly benign, can be used to make concrete building blocks.

However, incinerators are fairly technology-heavy, rendering them unsuitable for many developing country contexts.

A problem that we’ve witnessed is that waste management companies from industrialised nations try to wholesale their technology in developing countries. The technology is usually unaffordable, and even if the capital can be raised to procure a facility, as soon as something breaks down the whole solution can fall apart.

There is a need for information about simple waste processing technologies to become more open-sourced. Smart future-thinking businesses could capitalise on selling blueprints rather than entire prefabricated facilities. Most of the time it’s far cheaper to fabricate something locally, and also means that when something breaks it can be fixed.

The continuing need for landfill

The fact is that in most cases, a standard, lined landfill site with landfill gas capture is still the most appropriate answer for non-recyclable waste. Add to that a well-organised, low-cost waste collection service with source separation of recyclable materials and biodegradable waste, and you have a relatively affordable solution that is better for the climate, better for health, better for the local economy, and contributes to a more sustainable future.

Landfill may seem very unfashionable to those of us who work in the recycling sector, but nevertheless it will remain a necessity both in developed and developing countries for the foreseeable future.

Joining forces and stepping stones

The success of the Sustainable Development Goals and potential Climate Change Agreement depend on developed and developing countries working together. Miguel Arias Cañete, the EU climate commissioner, said the Climate Coalition alliance showed that developed and developing countries could work together with a common interest. “These negotiations are not about them and us. They are about all of us, developed and developing countries, finding common ground and solutions together. We urge other countries to join us. Together we can do it.”

Necessity is the mother of invention, and we are facing a waste crisis of unprecedented proportion. The potential for waste management in reducing GHG emissions has never been more pertinent. Waste and development practitioners, academics and entrepreneurs around the world are working together more and more to help bring about the change we want to see, which will benefit the billions of people suffering from poor waste management, and the rest of us who share a warming planet – and share the burden of climate change and poverty.

By sharing knowledge through platforms such as beWasteWise and ISWA, and through initiatives like WasteAid, WASTE and Wiego, we can start making a dent in this very large problem.

No silver bullets, but lots of small stepping stones in the right direction.

Green SMEs: Catalyst for Green Economy

  By | | , ,
11 Comments

With ‘green’ being the buzzword across all industries, greening of the business sector and development of green skills has assumed greater importance all over the world. SMEs, startups and ecopreneurs are playing a vital role in the transition to a low-carbon economy by developing new green business models for different industrial sectors. Infact, young and small firms are emerging as main drivers of radical eco-innovation in the industrial and services sectors.

Green SMEs

What are Green SMEs

Green SMEs adopt green processes and/or those producing green goods using green production inputs. A judicious exploitation of techno-commercial opportunities and redevelopment of business models, often neglected by established companies, have been the major hallmarks of green SMEs.

For example, SMEs operating in eco-design, green architecture, renewable energy, energy efficiency and sustainability are spearheading the transition to green economy across a wide range of industries. The path to green economy is achieved by making use of production, technology and management practices of green SMEs. Impact investment platforms allows individuals to invest in environmentally sustainable companies.

Categories of Green Industries

Environmental Protection Resource Management
Protection of ambient air Water management
Protection of climate Management of forest resources
Wastewater management Management of flora and fauna
Waste management Energy management
Noise and vibration abatement Management of minerals
Protection of biodiversity and landscape Eco-construction
Protection against radiation Natural resource management activities
Protection of soil, groundwater and surface water Eco-tourism
Environmental Monitoring and Instrumentation Organic agriculture
Research and Development Research and Development

Key Drivers

The key motivations for a green entrepreneur are to exploit the market opportunity and to promote environmental sustainability. A green business help in the implementation of innovative solutions, competes with established markets and creates new market niches. Green entrepreneurs are a role model for one and all as they combine environmental performance with market targets and profit outcomes, thus contributing to the expansion of green markets.

Some of the popular areas in which small green businesses have been historically successful are renewable energy production (solar, wind and biomass), smart metering, building retrofitting, hybrid cars and waste recycling.

As far as established green industries (such as waste management and wastewater treatment) are concerned, large companies tend to dominate, however SMEs and start-ups can make a mark if they can introduce innovative processes and systems. Eco-friendly transformation of existing practices is another attractive pathway for SMEs to participate in the green economy.

The Way Forward

Policy interventions for supporting green SMEs, especially in developing nations, are urgently required to overcome major barriers, including knowledge-sharing, raising environmental awareness, enhancing financial support, supporting skill development and skill formation, improving market access and implementing green taxation.

In recent decades, entrepreneurship in developing world has been increasing at a rapid pace which should be channeled towards addressing water, energy, environment and waste management challenges, thereby converting environmental constraints into business opportunities.
