Limited petrol resources and Increasing environmental concerns and strict regulations on emissions of toxic chemicals have forced the wood composites industry to develop environmentally friendly alternative adhesives from abundant renewable sources. However, these types of adhesives suffer from technical disadvantages because of their poor water resistance and low strength properties. One of the possible alternatives to petroleum-based fuels and products are algae and DDGS. Cambond are developing Alglue© and Diglue© for the wood panel industry to address the emission of the toxic formaldehyde and large consumption of the petrol natural sources problems. The technology also has the potential to open up new niche markets in the field of medical application of bio-adhesives for tissue repairing because of its natural strong adhesion properties with strong water resistant capability. Two UK patent applications have been filed in biomass based adhesives and further patents regarding niche application of the Alglue platform is under way.
The Alglue© technology platform is based on our discovery that algal biomass has the strong ‘sticky’ properties achieved by a simple mechanical blending of the algal materials with inorganic and polymeric crosslinking agents to form a solid blend. The blend will be further milled into micron powder which can be readily to be used for the aqueous bio-adhesive formulation in the wood panel manufacturing site.
The company makes low carbon adhesives from biomass feedstocks and provides a way to manufacture ‘green’ sustainable adhesives in a cost effective manner world widely.The patented Biomass Crosslinking and Blocking (BCB) technology has been named in the prestigious 2014 Royal Soceity of Chemistry Emerging Technology Competition Finalists.
