Fire resistant applications for wood waste

A European initiative has developed new high added value fire retardants produced from environmentally friendly biopolymers.
Fire resistant applications for wood waste
The EU-funded project BRIGIT (New tailor-made biopolymers produced from lignocellulosic sugars waste for highly demanding fire-resistant applications) was established to develop a continuous cost-competitive and environmentally friendly process. This process would be used for producing the biopolymer polyhydroxybutyrate (PHB) and the biopolyester polybutylene succinate (PBS).

Researchers exploited existing sugar-rich waste streams from the digestion of hardwood chips as they do not compete with the food supply. The fermentation process was conducted using the spent sulphite liquor from the wood sulphite pulping process. The biopolymers obtained revealed properties comparable to commercial materials. By blending the biopolymers with flame retardants, BRIGIT developed bio-based compounds for fire-resistant applications in the transport sector.

The biopolymers will be used in combination with natural fibres and cork in trucks and buses. They will provide a sustainable and cost effective alternative to traditional three-dimensional sandwich panels.

The new panels will be recyclable and lighter than the conventional panels. With low embodied energy, they can be produced in high numbers using a continuous compression moulding process. This will help reduce resource consumption and greenhouse gas emissions and lower operational costs by obviating the need for waste transport.

Advances in bioplastics techniques to produce PHB and PBS will benefit the EU plastic industry providing high added value and innovative products. These sustainable BRIGIT methodologies will strengthen the industries’ competitiveness in the global market place.
