Puidukütused

Puidukütused refers to solid fuels derived from wood and wood processing residues. This category encompasses a range of biomass materials used for heating and energy production. Common forms include firewood, wood chips, wood pellets, and wood briquettes. Firewood is typically logs or split pieces of wood, often used in domestic fireplaces and stoves. Wood chips are smaller fragments of wood, suitable for industrial boilers and larger heating systems. Wood pellets are compressed sawdust and wood shavings, standardized in size and density for efficient combustion in pellet stoves and boilers. Wood briquettes are similarly compressed wood waste, forming denser blocks than pellets, also used in stoves and boilers.

The production of puidukütused often utilizes by-products from forestry and the timber industry, such as sawdust, wood shavings, and bark, which might otherwise be considered waste. This makes them a renewable energy source, as trees can be replanted to replenish the supply. The combustion of wood fuels releases energy that can be harnessed for heat or electricity. However, the environmental impact depends on sustainable forestry practices and the efficiency of the combustion process. Inefficient burning can release particulate matter and other air pollutants. When sourced sustainably and burned efficiently, puidukütused can be a low-carbon alternative to fossil fuels, contributing to reduced greenhouse gas emissions. Their use is prevalent in many regions with abundant forest resources.
