COCOBIN: Coatings and Composites from Novel Biobased Dispersions

There is a pressing need to substitute fossil-based polymers in various emerging products such as packaging and composites, and to further facilitate the recyclability of single-use products to reduce waste, slow down climate change and help in transition towards circular bioeconomy. The COCOBIN project aims to reduce the carbon footprint of dispersion coatings, adhesives and binders, and increase their recyclability and minimize waste by developing biobased multicomponent materials.

Project description

The COCOBIN project will explore and pilot the use of various natural waxes and polyesters together with cellulose and hemicellulose materials for coatings and adhesives in fiber-packaging, textiles and abrasive materials. The project focuses on the performance and properties of biobased dispersion coatings and adhesives, as well as challenges related to the availability and cost of raw materials, which still limit the large-scale use of biobased materials. Additionally, the project examines the lifecycle and environmental impacts of new materials.

The initiative includes a comprehensive plan to scale up multicomponent dispersions, coatings, binders and adhesives from the laboratory stage to pilot-scale. The project also advances biomaterial development, its general acceptance, and a sustainable transition towards circular biomaterials economy to support future products relying on recyclable, non-toxic and biodegradable raw materials. The overall objective of the COCOBIN project is to enable biobased materials to become competitive alternatives for dispersion and composite formulations in the markets currently dominated by fossil-based polymers.
