DEEP PURPLE · CONVERSION OF DILUTED MIXED URBAN BIO-WASTES INTO SUSTAINABLE MATERIALS AND PRODUCTS IN FLEXIBLE PURPLE PHOTOBIOREFINERIES

DEEP PURPLE creates a holistic consortium to transform diluted urban bio-wastes, including mixed waste streams, organicfraction of municipal solid waste (OFMSW), wastewater (WW) and sewage sludge (SS), into feedstock for bio-industry toobtain sustainable bio-products. This revolutionary concept will be implemented in a novel Single-Site Multi-Platform Concept (Biomass, Cellulose and Biogas) to replace current polluting destructive practices with new value added concepts.The beneficial use of bio-waste is obtained by an innovative combination of optimized recovery technologies and novel solutions: the Purple Phototrophic Bacteria (PPB) PhotoBiorefinery. The use of PPB -the most versatile metabolismreported- ensures the adaption to fluctuating and diluted waste streams to support a stable and profitable production chain. Thefirst PPB PhotoBiorefinery in the EU (the biggest worldwide) will be validated in different environmental, economic, logisticand social scenarios.The concept will be implemented by end-users from four municipalities, namely Madrid (ES), Toledo (ES), and the Moravia-Silesia Region(CZ) to transform bio-wastes (OFMSW: 422 t/y, mixed waste: 438,000 m3/y) into high-added value bioproducts:fine chemicals (bio-cosmetics), fertilizers, bio-packaging and self-repairing construction materials. The marketuptake of DEEP PURPLE is facilitated by optimal logistics of bio-wastes conversion (reduction of landfilled OFMSW: 60%, WWTP, solids recovery: 71%), and bio-products quality to favor their commercialization (440 t/y). The integration of valuechains is boosted by relevant stakeholder’s participation and innovative business models, minimizing waste and maximizingbenefits (85 M€ benefits, GHG emissions savings: 11,300 tCO2eq/y in 2025). Key communities (social engagementstrategies) will participate in the new value creation, calibrating the returns of the project like social innovation promotion and creation of new opportunities along the urban value cycle.
