An integrated, modular biorefinery for the treatment of food waste in urban areas
Innovative and decentralized biorefineries are needed in urban areas to contribute to local resource efficiency. In this case study a biorefinery (waste-to-resource-unit, W2RU) is introduced for bioconversion of food waste using heterotrophic microalgae to protein-rich biomass, and for simultaneous...
