Woodchips

"Woodchipping" redirects here. For the sport of chopping wood, see Woodchopping.
Woodchips, with hand for scale

Woodchips are small- to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues, stumps, roots, and wood waste.[1][2]

Woodchips may be used as a biomass solid fuel and are raw material for producing wood pulp.[3] They may also be used as an organic mulch in gardening, landscaping, and ecosystem restoration; in bioreactors for denitrification;[4] and as a substrate for mushroom cultivation.[5]

The process of making woodchips is called wood chipping and is done using a wood chipper. The types of woodchips formed following chipping is dependent on the type of wood chipper used and the material from which they are made.[6] Woodchip varieties include: forest chips (from forested areas), wood residue chips (from untreated wood residues, recycled wood and off-cuts), sawing residue chips (from sawmill residues), and short rotation forestry chips (from energy crops).[6]
