The objective of the project is the development of a cost-optimized value chain for bio-based olefins and complex nutrient media based on insect biomass for technical applications. Starting from a low-cost nutrient substrate from residual material streams, high-quality insect proteins and fats are to be obtained which can be supplied to a large number of utilisation pathways. Relevant waste streams are e.g. brewery residues, by-products of biofuel production, sugar production and food industry and nitrogen-rich fermentation residues from biogas plants. As beneficial insects, black soldier flies (Hermetia Illucens) are used in the process to convert organic feedstocks into valuable insect biomass.
