Automating relative and absolute environmental sustainability assessments of bio-based products

[Display omitted] •An automatized sustainability assessment for bio-based products is presented.•The protocol integrates relative and absolute sustainability assessments for agile calculations.•GWP of 1 kg succinic acid corresponds to 5.46 kg CO2 eq and 3.82 kg CO2 eq for poly-lactic acid.•Transgression of planetary boundaries (ASR > 1) is observed in both succinic acid and poly-lactic acid production. Awareness of long-term environmental challenges has motivated society toward a more sustainable future. Biotechnology is expected to contribute to the transition towards sustainability. Automation can play an important role in this transition, enabling faster decision-making at early stages. Therefore, an automated relative and absolute environmental sustainability assessment is presented to boost innovation in biotechnology. The automated calculation methodology uses computer-aided tools (dedicated software and Python codes) for the fast quantification of the environmental sustainability performance of bio-based products including scenario and uncertainty analysis. Two case studies (i) succinic acid (SA) and (ii) poly-lactic acid (PLA) are evaluated to test the capabilities of the automated assessment. The results show a carbon footprint and land use of 5.46 kg CO2 eq and 1.26 m2a crop eq for SA and 3.82 kg CO2 eq and 0.74 m2a crop eq for PLA. Transgression of planetary boundaries was found in both SA and PLA production.
