More sustainable coatings form SuperBark project

More sustainable coatings: discover SuperBark, BIORING sister project

Can natural components in softwood bark be the base for safe, sustainable and high-performance adhesives and coatings?

This is what the Circular Bio-based Europe Joint Undertaking (CBE JU) project SuperBark explores, aiming at developing new bio-based adhesives and coatings for a range of industrial applications, with improved sustainability, health and safety profiles compared to fossil-based solutions.


Adhesives and coatings are an integral part of everyday products

Most adhesives and coatings currently on the market are produced using fossil-based and harmful chemicals, thus conflicting with the EU goal of protecting the health and well-being of citizens and the environment.

SuperBark steps in to develop bio-based products from industrial softwood bark (pine and spruce), a major side stream from the forest industry. SuperBark adhesives and coatings will be applied in industries such as furniture, construction, transport, and packaging, eliminating formaldehyde-based resins and other harmful fossil-based substances currently used and improving the recyclability and sustainability of the new products.


SuperBark objectives

The project main objectives are:

  1. Produce bio-based components for adhesives and coatings from industrial softwood bark.
  2. Develop adhesives with more than 95% bio-based content from bark for plywood, particleboard and medium-density fibreboard.
  3. Develop coatings with more than 95% bio-based content from bark-based cellulose for plywood and packaging paper.
  4. Apply a Safe-and-Sustainable-by-Design (SSbD) framework to guide the development of new products.
  5. Develop digital tools to support the scale-up and market integration of the adhesives and coatings.
  6. Increase awareness of these new technologies, products, and associated opportunities.
