small wood pellet machine for sale

Wood pellets are usually made from wood waste material such as sawdust from lumber mills and parts of a log that are unsuitable for making lumber or other wood products. Sometimes even whole trees are chipped and made into pellets. This can be a good way to utilize low grade trees or parts of trees that may have otherwise gone to waste in a forestry operation.

Pellets didn't catch on as a source of fuel until the late 70's. Before then pellets were made from mostly agricultural materials like alfalfa and grains as animal feed and bedding. Pellets can be made from just about any organic material for both heating and other uses.
