How does Accoya® wood differ from wood that has been impregnated or modified in other ways?
Virtually all wood preserving treatments today work by impregnating toxic chemicals (such as arsenic, oils, ammonia or metal compounds) into the cell walls of the wood, filling the voids but not changing the underlying chemistry of the wood. This controls unwanted organisms, such as bacteria, viruses and fungi, by creating an inhospitable environment. However, the toxicity of such products has environmental implications, both during the serviceable life of the wood and for its safe disposal. By contrast, Accoya® wood is non-toxic and 100% recyclable.
