Biomass transforms the organic content of sewage and municipal waste into raw materials for biofuels, plastics, cellulose and new base materials in the chemical and cosmetic industry. Within the framework of the Deep Purple project, a photo-biorefinery is already under construction at the Estiviel WWTP (Toledo) and the construction of another in Linares is planned for 2021.
