Bio-impregnation for wood
Bio-impregnation for wood displaces chromated, solvent-based and petrochemical wood preservatives and finishes with renewable-feedstock chemistry: the Netherlands' Accsys Technologies acetylates solid wood and wood elements with acetic anhydride to produce Accoya and Tricoya, while Denmark's WOCA and Germany's Osmo deep-impregnate exterior and interior wood with low-VOC natural oils. Canada's Sansin Corporation finishes both traditional and acetylated wood with water-borne natural-oil stains, and Vermont's Vermont Natural Coatings replaces solvent-based polyurethane with PolyWhey, a patented finish built on whey protein, a dairy-processing byproduct.
