This group aims to critically assess the policy landscape surrounding bio-based materials and circularity, identify key challenges and inconsistencies, and develop evidence-based recommendations to ensure policies support, rather than hinder, sustainable innovation.

Key questions

  • What guidelines, standards or regulations are needed to assess and compare LCA of bio-based and recycled materials with fossil-based materials?
  • Does current LCA practice allow assessment of circular economy goals, and if not what guidelines and methodology developments are needed?

Working Group 2: Outputs Report: Bio-based and Upcoming Materials

This report presents a glossary of key terms alongside four case studies that examine the challenges associated with applying LCA in biobased and emerging systems. The glossary clarifies terminology commonly used in biobased and circular contexts, while the case studies (biofuels, circular materials, construction, and novel biomaterials) illustrate methodological issues including the treatment and storage of biogenic carbon, the modelling of circularity, and approaches to allocation and avoided impacts.
