1. Wood fuels

1.1 Origins

Numerous wood deposits are available and can be used to produce fuels after a more or less extensive conditioning phase:

• forestry operations (logging, skidding, pruning, etc.);

• Primary wood processing (sawmills, panels, etc.);

• secondary wood processing (joinery, furniture, construction);

• the packaging industry: pallets, crates... ;

• demolition and renovation companies;

• landfills and waste disposal sites.
