Wood panels (plywood, MDF etc.) are a huge ($400Bn) a year industry. They are made from wood fibers mixed with adhesive. The adhesive (formaldehyde based) is derived from oil and has toxicity and environmental issues. The regulatory environment controlling formaldehyde emissions is changing and tightening in the US, Asia and EEC in 2016/7. Formaldehyde will become more expensive to handle and dispose of and products containing it will have to meet tighter commercial standards. The woodpanel industry is looking for a better alternative but has yet to find one.
Cambond has invented a ‘green’ biomass based adhesive to make wood panels. We can make wood panels to meet industry standards using large scale manufacturing systems. Cambond resin is manufactured using protein containing biomass such as DDGS (bioethanol and whisky distillation by products) or algae. They are mixed with small amounts of a cross-linking agent and water before use.
Cambond resin is low/non-toxic, sustainable and environmentally friendly.
LCA studies indicate that woodpanels manufactured with Cambond resin have reductions of >40% in their carbon footprint.
Cambond’s technology offers the opportunity to lower the carbon footprint of a global industry enabling the production of sustainable, environmentally friendly green products for the built environment.
Cambond will compete with soy based adhesives (Soyad) and other non-formaldehyde adhesive manufacturers. Currently these competitors suffer from cost or technical limitations.
Cambond has a cost advantage (also an additional advantage in no complex chemistry and simpler regulatory environment).
Cambond have discovered during the course of an R&D programme that the Cambond resin can be formulated with biomass (straws, oat husks, peanut shells etc.) and polymers to form biocomposites. Initial laboratory trials and limited development work have shown that these materials (Camposites©) appear to be useful as a DIRECT substitute for wood fibres in panels or plastics (e.g. polypropylene) in existing manufacturing processes. In effect plastics in many products could be replaced by a more environmentally friendly and lower carbon type of biopolymer.
Of critical importance is the estimated costs of these Camposites©. Our calculations indicate that the feedstock Camposite© to replace polypropylene could be manufactured at a 5-10% reduction in cost compared to standard plastics.
