Starch as a replacement for urea-formaldehyde in medium density fibreboard

Medium density fibreboard (MDF) is a ubiquitous product formed from wood flour and a formaldehyde-based resin. The use of the latter component causes some health and environmental concerns and its use is restricted. The current study shows that thermoplastic starch can be used in place of the thermoset resin to produce materials of similar mechanical strength but with clear environmental benefits. All of the components are compostable and the resin being a thermoplastic allows the potential for remoulding and recycling which has clear environmental impact benefits.
