Proposals under this topic should:

• Demonstrate cost-effective, robust, sustainable, large-scale production processes for obtaining bio-based drop-in (including smart drop-in) platform chemicals at end TRL: 8. Both upstream and downstream process aspects are in scope. Bio-based drop-in platform chemicals should be analogues of fossil-based chemicals that are not substances of very high concern (SVHCs).
• Target resource efficiency, minimisation of the E-factor (process waste), as well as process safety aspects. The cascading valorisation of secondary biomass and residual streams is also in scope.

Demonstrate the further conversion and integration of produced chemical(s) into market-relevant final product(s) (reaching an end TRL 6 or higher). In addition to the specific requirements applicable for the type of action, as described in section 2.2.3.1 Specific requirements of the CBE JU Annual Work Programme 2025, proposals under this topic should:

• As part of the Multi-Actor Approach (MAA), ensure adequate involvement of key actors most relevant for achieving the objectives of the project from across the sustainable circular bio-based system, including B2B end-users and feedstock providers.
• Include a task to apply the safe-and-sustainable-by-design (SSbD) framework, developed by the European Commission for the assessment of the platform chemicals’ production process as well as the chosen final products derived from the drop-in platform chemicals. Under this context, projects are expected to also contribute with and develop recommendations that can advance further the application of the SSbD framework.
• Address compliance with regulatory frameworks, considering the targeted platform chemical(s) and related impurities’ type and concentration.
