Can you make glue from corn or potatoes? It might sound far-fetched, but the ongoing search for adhesives with a greener environmental profile has led to the development of systems based on renewable resources, including starch. The need for an alternative solution has largely been brought about by health and safety concerns over certain compounds contained in adhesives. This has prompted the introduction of tougher legislation – notably in countries such as Japan and the US – which in turn has created market demand for products with, for example, less formaldehyde and VOCs.
As a major supplier of wood adhesives to laminated beam producers and the furniture and flooring industries, Casco Adhesives (part of AkzoNobel Industrial Finishes) has been working hard to harness the known adhesive potential of renewable resources such as starches and soya beans and combine them with innovative but safe chemistry to create a system which meets customer needs.
During development of these so-called bio-adhesives, AkzoNobel has focused heavily on ensuring that the eco profile holds all the way from the raw material source, to the production of the adhesives themselves, to the workers’ environment and finally to the ultimate application, be that on furniture or cupboards.
Various adhesives have already been extensively tested in different applications – including furniture and particle board – with very encouraging results. A number of large-scale trials are also planned for 2009.
