Circular Bioeconomy metrics and Life Cycle Assessment. Answers from literature review.

Resource scarcity and the problem of waste management are two of the key issues in contemporary society that encourages the reflection on the benefits of transitioning to a Circular Economy (CE) model. Bioeconomy, the socio-economic system that encompasses and interconnects economic activities that use renewable bio-resources of the soil and sea (also called bio-based resources) to produce food, materials and energy, represents a fundamental variation of the CE. In the analyzed context, where it is necessary moving towards CE and reducing the environmental impacts, a systematic literature review was conducted using different keywords combinations. Results show that Material Circularity Indicator (MCI) and Life Cycle Assessment (LCA) could be two reliable metrics by which measure Circular Bioeconomy and environmental impacts, respectively.
