Accoya wood starts life as a fast-growing pine tree (Pinus radiata) grown in managed forests. The pine tree is harvested once it reaches maturity at around the 30 year mark. The raw timber goes through an acetylation process using acetic acid which creates extremely dimensionally stable and durable wood that is nontoxic.
