W.T.T. specialises in the purchase of wood, in particular coniferous woods, and of biomasses used in the energy sector.
The sawmills currently looked after by W.T.T. procure their wood mainly from the Ardennes, the Belgian and German Eifel, Luxemburg and northern France.
The biomasses are primarily bark, sawdust, wood chips, offcuts and residual materials from the wood processing industry, mature timber, grass clippings and other residual forestry and agricultural products from the procurement region of the Benelux states, Germany and France.
