| Zusammenfassung: | Copyright © 2024 The Authors. Published by Elsevier Ltd.. All rights reserved. Bio-based products are a fast-growing market due to increasing consumer consciousness for sustainability. Although this is per se a positive trend, it leads to a higher demand for organic feedstocks which normally comes from primary agricultural sources and can lead to undesired deforestation or other land use changes to farmland. At the same time, Europe is facing another challenge related with the treatment of organic wastes. In this context, the project CAFIPLA developed an integrated process to convert heterogeneous organic materials to building blocks for the bio-based economy. This study performs a life cycle sustainability assessment (life cycle assessment, life cycle costing and social life cycle assessment) of the production of short chain carboxylic acids (SCCA) employing municipal bio-wastes as a feedstock. In addition to a hot-spot identification to detect the main sources of impact, a comparison of the novel technology with the current benchmark is carried out applying a cradle-to-gate approach and using 1 kg of SCCA as a functional unit. Results show the great performance of CAFIPLA in all the environmental categories analysed. Furthermore, the profitability of the plant is also verified, reaching a payback period below 6 years as long as the product is sold above 0.49 €/kg. Finally, the potential social risk associated to the supply chain is also improved with CAFIPLA technology |
