Black Soldier Fly (BSF) is an insect with noticeable nutritional content. The adult fly does not constitute a vector of diseases & is tolerable with a broad spectrum of environmental conditions. BSF larvae can thrive on different waste streams, including urban organic wastes & agricultural waste or underutilized crops. They reduce mass of waste efficiently, leaving behind a nutrient rich residue while they self-forming into protein-rich larvae. The resultant BSF larvae could harness as an alternate nutritious agriculture or aquaculture feed for farm animals such as swine, poultry & fish. The residue can be used in agribusiness for making natural fertilizers. This book gives an extensive overview of the BSF & BSF-based technology. It covers the different components, (1)life cycle of BSF (2)medium-scale BSF farming facilities and parameters (3)nutrient recapture through waste treatment & product harvesting (4)various aspects of the emerging BSF technology. For each of these key components, the book describes the recommended operating conditions & possible designs for local farmers. It also reviews the economic, environmental, legal & social aspects of the BSF-based treatment method.
