Selection of case studies
In deriving policy recommendations for the transition to a circular bioeconomy, SUSTRACK focuses on four highly carbon-intensive sectors (chemicals, textiles, plastics, and construction). To get a clearer grasp of the challenges and good practices facing these sectors, 10(+1) case studies (2 or 3 per sector) have been defined and analysed in further detail. Each case study represents an existing bio-based value chain and is compared against its fossil-based counterpart. The figure below shows an overview of the selected case studies, with links to factsheets providing more information.
For each case study, the analysis follows the same structure. It starts with a general description of the value chain of interest, followed by a stakeholder mapping. In addition, the bio-based system is analysed from three dimensions (market, policy, and sustainability).
Value chain
To provide a comprehensive overview of the life cycle of each case, a value chain diagram was created detailing every critical step. The value chain covers the steps from the sourcing of the feedstock, through its processing, manufacturing and consumption to reach its end-of-life treatment. The figure below provides an example, referring to the interlinked stages of the Lyocell value chain, which is part of the man-made cellulosic fibre case.
Stakeholder mapping and analysis
A stakeholder analysis was performed for each case study. The relevant stakeholders were identified and mapped, distinguishing between actors directly involved in the value chain of interest, and those part of the enabling environment (government, academia, industry and civil society). Next, the influence of each stakeholder on upscaling the bio-based value chain was determined and represented in a power-interest matrix. This analysis will help to understand whom the key players in the industry are and how the transition from fossil-based to bio-based can be facilitated by their action.
Value chain analysis
The value chains of interest were analysed from three perspectives, or dimensions: policy, sustainability and market. For each case study, a policy mapping was conducted, relevant sustainability indicators were described alongside research gaps, and an overview of the current and expected future market was detailed. On top of a (grey) literature review, this analysis was supported by the DESIGN Conference “Pathway to DESIGN the Circular Bio-Based Transition” series of four sector-specific workshops, which allowed different key players to provide their input. This work resulted in the identification of major challenges and possible actions that can be taken to facilitate the transition toward a circular bioeconomy. The results of the workshops were presented on the closing conference and can be found in this link. Currently, follow-up interviews with key stakeholders are carried out to deepen the analysis.
Main takeaways
Although the analysis of the mentioned case studies is still in progress, some interesting findings have already emerged. The transition to a circular, bio-based economy has no golden bullet. Rather, this complex transition requires a multiplicity of actions on different fronts, exploiting synergies within and between sectors. Far-going collaboration between key actors is fundamental to accomplish the sustainability targets of the European Commission.
Next steps in SUSTRACK
As SUSTRACK proceeds, the case study-generated insights feed into other project activities. Notably, the case studies are used to design, test, and validate different methodologies and tools (e.g., the Bioeconomy Assessment and Monitoring Framework and the customised Green Economy Model). Also, the findings will be utilized to support the collection and prioritization of policy recommendations.
