BIO4COAT

Biobased building blocks from biorefinery for safe diamond-like and biopolyurethane coating solutions under extreme and demanding conditions of use and end-of-life

Expected results:

BIO4COAT aims to validate at TRL 5 the use of three biobased building blocks (1,4-bioBDO, lcDCA, and biomethane) from Novamont’s biorefinery for producing safe and sustainable biobased coating solutions. Two value chains are planned:

  • A supply of first-of-their-kind polyester-polyols from 1,4-bioBDO and lcDCA for conversion into polyurethanes, to be used to create 1K PUD and 2K PUR in 7 prototypes.
  • A second supply chain to purify biomethane in creating DLC coatings via CVD for high-temperature plastic processing tools.

The performance will be tested in terms of surface protection, printability, and controlled release under demanding conditions, with added recyclability, compostability, and no bioaccumulation, across eight sectors: plastics, hygiene, textiles, agriculture, horticulture, furniture, energy, and construction.

BIO4COAT will implement a comprehensive SSbD methodology, guiding the development of biobased coatings with reduced (-20%) GHG emissions, allowing multiple EoL scenarios, and minimizing bioaccumulation risks. BIO4COAT’s upscaling insights are aligned with the CBE-JU TERRIFIC project and include feasibility analyses and business models.

BIO4COAT dissemination, exploitation, and communication efforts will maximize the visibility and impact of project outcomes. The engagement with stakeholders and the clustering activities will be performed at two levels:

  • along the overall value chain, and
  • with a focus on technical actors with the set up of two technical working groups with other EU-funded projects.

Key impacts are expected in long-term progress in bio-based materials science and engineering, cost savings for industries by 30%, increased biodiversity and environmental health due to reduced pollution and sustainable resource use, expansion of the market for bio-based coatings, and enhanced competitiveness of European small and medium enterprises.
