The project CIRCULAR-FUEL is an integrated 4-year program focused on knowledge transfer and networking among seven partners. These include one Spanish university, the University of Sevilla (UoS); two Spanish companies, GREENE ENTERPRISE S.L (GreenE). and Vortico; one Italian university, the Polytechnic University of Milan (PoliMi); one German university, the University of Hohenheim (UHOH); one UK university, the Queen’s University Belfast (QUB); and one UK company, GreenX Technology Ltd (GreenX). The project will directly address biomass utilization challenges by researching and developing innovative approaches for sorting and recycling biowaste into value-added chemicals and materials through several pathways. This effort will subsequently expand to encompass a wider range of biomass species by incorporating process simulation and machine learning.
