Accoya modified wood has become the timber industry benchmark when it comes to performance and sustainability. No other timber offers the same combination of durability, stability and versatility. Sustainably sourced, and with a low total lifetime carbon cost, Accoya actively contributes to a circular, bio-based economy.

Wood to change the world

Accoya wood is made by Accsys at its plant in Arnhem, in the Netherlands.

Accsys transforms fast-growing, certified sustainable wood into Accoya wood through its proprietary acetylation process.

The result is high performing sustainable lumber with sustainability credentials that exceed those of man-made, intensely resource depleting and heavily carbon-polluting alternatives.

This gives the world the choice to build sustainably, offering new opportunities in sustainable building materials.
