| Abstract | To stay within the planetary boundaries circularizing economy by utilizing residues is key. Bioprocesses can leverage abundant, but recalcitrant biogenic residues, giving access to various value-added products. Accelerating circularization requires assessing the feasibility of heterogeneous biogenic residues for different, yet specific bioprocesses. Exemplifying the national level in Germany, we categorized biogenic residues compiled in the DE Biomass Monitor regarding biochemical composition and feedstock potential in a resource matrix, detailing their fractions and the quality of available data. Three biotechnological processes, making use of lignin, non-fibrous carbohydrates, and oil, respectively, served as model processes to assess the biogenic production potential. By developing material flows based on state-of-the-art conversion routes, we found that residue-based production via all three biotechnology examples can meet national demands of specific polymer precursors, medium chain carboxylates, and platform chemicals respectively, when mobilizing only 20-30% of possible raw materials. The accruing side streams underline the importance of cluster approaches early in bioprocess development. Specific challenges to fully exploiting the potential of biogenic residues were identified, including legal and acceptance issues, the need for intelligent biomass decomposition in networked production, and residue availability and management. This study provides a framework for integrating biogenic residues with biotechnological production, using the resource matrix and an initial material-to-product estimation to advance a circular economy. |
