Organic Wastes - Biogas - Cooking fuel Conversion
Explain your idea in details:
Nigeria is among the countries with the highest Municipal Solid Wastes (MSW) generation in Sub-Saharan Africa, due to her population of over 150million, of which over 54% of the overall MSW composition are organic wastes such as kitchen food wastes, vegetables, garden wastes, animal dungs, poultry litters, etc. Presently, these organic wastes are discarded on unauthorized dumpsites and absurd locations in the neighbourhood or perhaps ended up on landfill.Consequently, this often leads to environmental pollution and loss of potentially recoverable valuable resources. Her citizens are often prone to chronic health problems from the contamination of waterways by pathogens and nutrients from human & animal wastes, high incidence of upper respiratory diseases. Also health problem from carbon black emission is a major concern and is most prevalent in the rural areas as a result of burning of solid wastes. The adverse effect of this indecent MSW disposal is part of the reasons why Nigeria records one of the lowest average life expectancy in the world, which is 47.5years. Our proposal to solving these frightening challenges is to produce and install Biodigester device in various households. This appliance will convert household organic wastes such as food scraps, kitchen wastes/leftovers, vegetables, garden wastes etc. to biogas which is used as cooking fuel. Each household is empowered to recycle their organic wastes to valuable resources – clean cooking fuel at an affordable cost. This initiative would encourage each household to safeguard their wastes with the knowledge that these wastes can be converted to valuable resources. Consequently there will be significant reduction of littered organic wastes and ultimately ensures availability of clean and affordable cooking energy in the future.Biogas can adequately substitutes the conventional domestic energy sources, reducing reliance on fossil fuel and firewood burning for cooking in most rural areas in developing countries
Expected impact of your idea on sustainable development
Our project is aimed at promoting and developing sustainable waste management in Nigeria. According to National Bureau of Statistics, Accenture Analysis, our target market is over 29million households which include the Rural Poor, Rural Survivor, Urban Poor, Urban Survivor and Urban Low Income Professional. The production and installation of Biodigester device would empower the citizens to convert their household organic wastes (used products) to cooking gas (valuable resources) at an affordable cost. The appliance can convert household organic wastes into enough cooking gas for at least two hours on a daily basis. This project would also accomplish the following benefits: (a) Improved indoor air quality: According to a research, over 22 million households in Nigeria depend on firewood/sawdust for cooking, which leads to about 90,000 deaths annually as a result of Indoor Air Pollution (IAP).Combustion of solid biomass causes respiratory infections in children, adverse pregnancy outcomes, chronic lung diseases and heart diseases, and cancer. (b) Provides an alternative to unsustainable deforestation: One cause of deforestation is the use of wood fuel for cooking and lighting. Introduction of Biodigester device and the use of biogas for cooking reduce wood fuel use and therefore reduce deforestation, which is a major economic loss to the nation. (c) Provides treatment of human and/or animal waste: Prevents nutrient runoff into water basins which drain to ocean environments, creating environmental problems. Prevents possible diarrhea disease downstream. (d) Protect women: Most women typically spend more time on indoors cooking, and therefore, have a disproportionate exposure to indoor air pollution from combustion of solid biomass fuels. They are more likely to develop chronic health problems related to exposure to particulate matter.
Plans for implementation and sustainability
The proposed Biodigester device is an outdoor appliance which will be suited in a place that is exposed to weather. The appliance functions well in warm and hot climates where the average day/night temperature is more than 15°C as we have in Nigeria. Our plan is to install the appliance at no cost to the Rural Poor, Rural Survivor and Urban Poor but a Pay-As-You-Use Model would be adopted such that the residents would pay a token before they can use the cooking gas while the Urban Survivor and Urban Low Income Professional would be encouraged to go for an outright purchase. The installation of this Compact Biodigester device would promote a cleaner, greener, friendlier and healthier environment. As such we seek for financial sponsorship for the actualization of this vision of ‘’GREENER NIGERIA’’ where no organic waste exist and where no person is harmed by chronic health diseases from wastes; a nation where her citizens have access to sustainable and affordable clean cooking gas.
I’m a Thirty Four- year old Business Development Professional with a Graduate Degree (B.Sc.) in Geology and a Postgraduate Degree in Applied Geophysics (Exploration option). During my year of studies, I developed keen interest in energy production especially renewable energy. Due to my passion for renewable energy, I researched on all the renewable energy resources, and I restricted my focus to Biomass - majorly wastes. Thus, had a certification in “Municipal Solid Wastes Management (MSW) in Developing Countries’’ by Sandec / Eawag. Also I'm a member of both Energy Recovery Working Group and Young Professional Group (YPG) of the International Solid Wastes Association (ISWA). All my interests and plans are channeled towards revamping the state of the environment, promoting and developing sustainable waste and energy management in Nigeria.
