Economic Potentials of Using Black Soldier Flies in Transforming Solid Bio-Waste Into Animal Feeds to Mitigate Greenhouse Gases Emission in Tanzania

Abstract

Tanzania's waste generation increases with national population growth and urbanization. Coupled with linear waste management approaches practiced in Tanzania, the waste aggravates greenhouse gases (GHGs) emissions and defeats Sustainable Development Goal 13 intending to minimize GHGs emissions through waste close loop management options. This paper advocates for the use of Black Soldier Flies (BSF) farming to mitigate the emissions and convert bio-waste into resourceful animal feeds. The review shows that bio-waste accounts for two-thirds of the national municipal solid wastes generated. The BSF farming is envisaged to reduce bio-waste by 50% and transform the GHGs into harmless compounds to get rid of their health-related concerns. It is recommended that further investigation for economic feasibility of BSF farming is conducted to inform potential investors about the viability of BSF investments in Tanzania.
