Harvest Wastes

Forest residues typically refer to those parts of trees unsuitable for sawlogs – treetops, branches, small-diameter wood, stumps, leaves, dead wood and even poorly-formed whole trees – as well as undergrowth and low-value species. While applications may exist for any individual constituent, the difficulty is determining whether there are sufficiently large quantities to warrant separation and harvesting.

If harvested, these residues are sometimes used for combustion or chipping for production of other usable feedstocks. Please see the harvesting section in this encyclopedia for more information.
