In what it has hailed as a "groundbreaking development", Greenwood Project has created a water-based product with silicates that enter the wood fibre, initialise and then accelerate the wood petrification procedure. A press release from Austria-based Greenwood added: "The product has the potential to revolutionise multiple wood industries with its practical applications from house constructions, to outdoor spaces as an ultra durable material for any wood project or other sustainable technologies." Wood petrification is the natural process where organic materials, such as wood, are gradually replaced by minerals over time, eventually turning the timber into a solid stone-like substance. Petrified wood is protected against termites, worms, fire, mould, rot, mushrooms, fresh and sea water and UV radiation. The G5 product from Greenwood Protect is certified by the Universities of Stuttgart in Germany and Mississippi in the USA and conforms to all EU norms.
