The use of black soldier flies in urban insect farming for sustainable waste management has gained attention as an innovative solution. The private sector has been encouraged to invest in this approach, recognizing its potential to effectively process organic waste and minimize its environmental impact.
The private sector’s involvement and investment in urban insect farming can accelerate the adoption of sustainable waste management practices, contribute to a circular economy, and address the growing challenge of organic waste. By harnessing the natural abilities of insects, particularly black soldier flies, the private sector can play a crucial role in promoting environmentally friendly solutions and driving positive change in waste management systems.
Black soldier flies, scientifically known as Hermetia illucens, have a remarkable ability to consume organic waste rapidly. During their larval stage, they efficiently convert various organic materials into protein-rich biomass. This biomass, commonly referred to as “frass,” holds significant value for applications such as animal feed, biofuel production, and organic fertilizers.
Dr. Ayub Macharia, the Director of Environmental Education Awareness at the Ministry of Environment and Forestry, emphasized the importance of private sector involvement during The World Circular Economy Forum 2023 Kenya Studio hosted by the African Circular Economy Network (ACEN) in Nairobi. He encouraged the private sector to explore the lucrative investment opportunity presented by farming insects, particularly using black soldier flies, as it allows for the effective utilization of readily available organic waste. Macharia also highlighted the benefits of organic fertilizer, which contains nutrients that are beneficial for soil health and not harmful to the environment.
While researchers have presented their findings on the use of black soldier flies for organic waste mitigation, it appears that the uptake of urban insect farming using this approach has been limited. However, the potential for reducing waste volumes, diverting organic waste from landfills, and creating value-added products through this method has been widely recognized.
The statements made by Dr. Ayub Macharia, Lara Maritano, and Festus Ngeno highlight the importance of adopting sustainable waste management practices and the potential benefits of using black soldier flies in urban insect farming. Kenya, in particular, faces significant waste management challenges, with an estimated 22,000 tons of waste generated per day.
The linear waste management approach, which involves mixing all waste and sending it to dumpsites, contributes to environmental issues such as greenhouse gas emissions and the release of methane as products decompose. To address these challenges, alternative solutions are needed.
The use of black soldier flies presents a promising opportunity for sustainable waste management. Nairobi alone generates over 2,000 tons of organic waste daily, which, if harnessed using black soldier flies, could create employment opportunities and produce valuable resources. The conversion of organic waste into protein for animal feed and the production of organic fair-trade products are among the potential benefits.
The African Circular Economy Network (ACEN) plays a crucial role in promoting circular economy principles and organizing events like the World Circular Economy Forum (WCEF) Studios. The WCEF2023 Kenya Studio aimed to make the forum’s knowledge and materials accessible to more African communities and showcased sustainable products from local entrepreneurs.
Zablon Wekesa, the ACEN Country Representative for Kenya, emphasized the importance of supporting the East African community with knowledge and financial resources to accelerate waste reduction and management efforts.
Overall, the messages conveyed by these individuals underscore the urgency of adopting sustainable waste management practices and the potential of insect farming, particularly using black soldier flies, as a viable solution to mitigate the environmental impact of organic waste.
