This report details the methodology employed in order to identify, select and map exemplary bio-based value chains for further analysis within the STAR-ProBio project. In order to determine their strengths, weaknesses, costs and benefits, a long-list of bio-based value chains was subjected to a systematic review of their promise with regards to a two-tiered set of criteria. Tier 1 covered analysis of feedstock variability, multi-regional supply chain, a variety of end-of-life options, gaps in sustainability schemes, EU preference feedstock, multi-sector application and potential for growth, and Tier 2 examined their relevance to target feedstock and technology preferences of EU-based bio-economy initiatives and other relevant sustainability schemes. The final resulting 4 bio-based values chains were mapped fully at each supply chain stage for visualisation of system dynamics, interconnections, chain actors, employed conversion routes, and existing/potential end-of-life options. These maps are made available in the report.
