Results : 25 % less on the electricity bill. In workshops near Lille (North)custom-made wooden furniture has been manufactured for three generations. Two years ago, the company was heating with gas, before moving and heating with wood chips.

Pipes suck up the shavings on each workbench, and the offcuts are crushed. These 400 tonnes of waste are then stored in two large silos.
