New ECODESIGN publication on the LCA of the EU project SUSTAINEXT
We are pleased to announce the publication of the paper “SUSTAINEXT: Validating a Zero-Waste, Dynamic, Multivalorization Route Biorefinery for Plant Extracts.”
The study presents the Life Cycle Assessment (LCA) of botanical extract production, from feedstock sourcing to the final polyphenol-rich extracts, within the framework of the EU project SUSTAINEXT. The LCA results shows that:
- The concentration of a given extract (for which more or less processing is needed), and the Feedstock Suitability Index (FSI) influence the environmental impacts.
- This LCA considers a cradle-to-gate system, and three allocation approaches of environmental impacts to the main product and co-products were modelled for the multi-output extraction processes. The polyphenol content-based and the economic-based allocation are the most suitable approaches for the valorization route investigated.
- Data for crops and feedstock sourcing and their pre-treatments (e.g., fertilizer use, water, pesticides, energy, transport, packaging, wastes, etc.) continues to be collected, as the crops continue to develop, and first-hand data becomes available from project partners. The LCA model will be refined accordingly.
