Bio-resins have the potential to form the basis of resins and adhesives for bonding construction products. Adhesives from crop residues and by-products can bond wood-based panel products or laminated timber sections in place of adhesives derived from petroleum. Bio-resins can also be used in paints and coatings. Improved recycling options at end of life and a potential lowering of the environmental impact of construction products are attractive targets, but there are challenges in delivering robust bio-resin systems. This Information Paper introduces bio-resins in the context of current synthetic adhesives and resins in construction. It analyses the opportunities, challenges and current status of their use.
