Nairobi: With land becoming scarce in urban areas, people are turning to biodigesters to save space and clean up waste.
According to Kenya News Agency, Edward Kirugo, the founder of Bio Tank Biodigester System, explains that biodigesters are tanks that digest organic matter and help manage waste effectively. These systems convert organic waste such as food leftovers and animal or human manure into renewable energy and fertilizer, thereby reducing greenhouse gas emissions.
Kirugo highlights the environmental and practical benefits of biodigesters, noting that they provide free cooking gas and replace polluting fuels like coal and wood. His company has completed over 3,000 installations in seven years, offering a compact solution that can be easily integrated into existing plumbing systems. In Kenya, where urban migration has increased waste generation, these systems present a sustainable alternative to traditional waste management practices.
Kirugo emphasizes that the waste management industry in Kenya faces challenges, including reliance on the informal sector for recycling and lack of government support. However, biodigesters offer a compact and onsite solution, addressing land scarcity issues. Kirugo also notes the potential impact of biodigesters on reducing carbon emissions and improving air quality, with the technology capable of saving significant amounts of water and reducing reliance on firewood.
The adoption of biodigesters is still low in Kenya, with only 22,000 systems in place, despite the continent’s potential for 32 million. Cost and lack of awareness are barriers to widespread adoption. Nevertheless, biodigesters present a significant opportunity for reducing methane and black carbon emissions while providing cleaner fuel for households.
The World Health Organization reports that air pollution causes approximately 19,000 deaths annually in Kenya. The biodigester technology not only addresses waste management but also contributes to food and nutrition security, potentially boosting incomes for households. Dr. Nelson Maara, Nakuru County Executive Committee Member, emphasizes the importance of ensuring biodigester technologies are functional and meet the energy needs of Kenyans.
Kenya’s National Determined Contribution aims to cut emissions by 32% by 2030, with biodigesters playing a role in achieving this target. The Kenya Biogas Programme reports that each biodigester can prevent deforestation and reduce carbon dioxide emissions significantly. Local climate actions, including the adoption of biodigesters, are critical in advancing Kenya’s commitments to global sustainability goals.
