Uprooted tree stumps. Stump harvesting is not a new process. Records of tree stumps being dug out of the ground for wood fuel go back hundreds of years in Europe. It was practiced in the 1970s in Swedish forests before declining in popularity, but is being considered again there now that there is a greater need for fuel wood.
The use of wood as a fuel source for heating is much older than civilization and is assumed to have been used by Neanderthals. Today, burning of wood is the largest use of energy derived from a solid fuel biomass. Wood fuel can be used for cooking and heating, and occasionally for fueling steam engines and steam turbines that generate electricity.
In rural areas, fuel wood is used for artisanal activities such as carving, woodworking, and crafting traditional items. [14] Charcoal production: Fuel wood is also a key raw material for charcoal production. Charcoal, derived from the carbonization of wood, is used for cooking, heating, and industrial processes.

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]
Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and cut to length directly at the stump. [1] CTL is typically a two-man, two-machine operation with a harvester felling, delimbing, and bucking trees and a forwarder transporting the logs from the felling to a landing area close to a road accessible by ...
Logging frequently has negative impacts. The harvesting procedure itself may be illegal, including the use of corrupt means to gain access to forests; extraction without permission or from a protected area; the cutting of protected species; or the extraction of timber in excess of agreed limits. [4] It may involve the so-called "timber mafia".
There are three general types of pellet heating appliances: free standing pellet stoves, pellet stove inserts and pellet boilers. Pellet stoves work like modern furnaces, where fuel, wood, or other biomass pellets, is stored in a storage bin called a hopper. The hopper can be located on the top of the appliance, the side of it or remotely.
In many areas, wood is the most easily available form of fuel, requiring no tools in the case of picking up dead wood, or few tools. Today, burning of wood is the largest use of energy derived from a solid fuel biomass. Wood fuel can be used for cooking and heating, and occasionally for fueling steam engines and steam turbines that generate ...
