What are wood pellets?
Wood pellets are standardised, cylindrical pellets made of dried, untreated wood. Sawdust and wood shavings from wood processing, for example, can be used as raw material. The wood is pressed into pellets under high pressure. Thanks to their low water content and high bulk density, wood pellets can be stored in little space. One tonne of pellets needs about 1.5 m³ of storage space.
Wood is a renewable raw material. Burning wood pellets releases CO₂. The carbon it contains was previously absorbed from the atmosphere while the trees were growing. In addition, further greenhouse gas emissions arise along the supply chain, for example from production and transport.
Wood pellets can be an alternative to fossil fuels such as heating oil or natural gas. However, prices for pellets and other energy sources can change depending on market supply, demand, energy prices and other factors.
