Sustainability consultancy 540 WORLD worked with Accsys and TEAM2100 to implement this important sustainability initiative, with a view to more widespread substitution of slow-growing hardwood with fast-growing, rapidly carbon-sequestering and very durable Accoya. The lack of toxic or plastic-based additives to Accoya is vital to its use in these environments, eliminating the risk of potential leaching into the water and environmental or ecological harm.

Each cubic metre of Accoya contains nearly one tonne of CO2e absorbed by certified sustainable forests, and keep that carbon safely stored for decades: it is warrantied for 50 years above ground, and 25 years in fresh water, with previous tests also indicating exceptional durability and integrity in marine environments. This installation in the Thames Estuary will provide further data on long-term performance, adding to the consensus of positive data from sites in the Mediterranean and North Seas.
