The MixMatters project aims to optimize the value derived from mixed biological waste. It will introduce a groundbreaking, integrated, and adaptable solution for efficiently harnessing the potential of mixed bio-waste. This solution comprises a modular separation unit and a dedicated valorisation hub tailored to the specific waste type. The project will conduct three demonstrations, with two of them taking place in Valencia and one in the Almería region of Spain. By implementing our innovative approach to separate and valorise 48 tons of mixed biological waste, our primary objective is to mitigate 21 tons of annual CO2 emissions during the demonstration phase. This sustainable initiative showcases our commitment to reducing environmental impact while maximizing the potential of bio-waste.
