UpWaste concentrates on the development of a flexible, modular and mobile system for the conversion of agricultural residues into heterotrophic microalgal (Galdieria sulphuraria) and insect (Hermetia illucens) biomass. The system converts residues, which are diverse and difficult to characterize, in high-quality biomass with defined composition serving as substrate in the formation of various products from food to chemicals by relevant industries. Focus is further on detection and avoidance of biological and chemical contaminations for assuring safeness of produced biomass and even allowing an application as food and feed. Socio-economic analysis of supply chains will be performed to assess social acceptance, economic feasibility and environmental impact. The project tackles the interconnected challenges of agriculture as well as sustainable intensification of the agricultural sector, efficient use of resources and lower GHG emissions.
