The VALUEWASTE project has opened a pilot plant in Cañada Hermosa, Murcia (Spain) to demonstrate sustainable technologies for the valorisation of urban biowaste. The facility processes the brown bin organic fraction through sorting, anaerobic digestion and digestate separation into solid and liquid fractions. From the liquid digestate, the plant recovers nutrients such as struvite and ammonium sulphate, which are used to produce high-value fertilisers. The solid fraction is transformed into protein-rich biomass through black soldier fly larvae cultivation. The pilot plant is part of an integrated circular-economy approach that converts municipal biowaste into valuable products, fertilisers, proteins and energy, while reducing waste and supporting sustainable urban resource management.
