In 2018, the consumption of wood fuels reached yet another record as a result of the increased use of black liquor produced by the forest industries. Heating and power plants consumed the same amount of solid wood fuels as in the previous year. In addition, the small-scale combustion of wood remained unchanged.

According to the statistics of the Natural Resources Institute Finland (Luke), heating and power plants consumed a total of 20 million solid cubic meters (38 terawatt-hours) of solid wood fuels in 2018, being the same amount as in the previous year and also more than ever before.

Consumption - Industry - By-products - Wood - Residues

"The consumption of forest industry by-products and wood residues decreased by 3 percent from the previous year to 11 million cubic meters," says Esa Ylitalo, Senior Statistician at Luke.

Bark comprised two thirds, or 7.7 million cubic meters, of all solid by-products consumed in energy generation, i.e. the same amount as in the previous year.

Total - Meters - Percent - Year - Types

A total of 2.5 million cubic meters (–11 percent from previous year) of different types of sawdust and 1.1 million cubic meters (–10 percent) of industrial chips were burned.

The consumption of wood pellets and briquettes decreased from the previous year to 0.2 million cubic meters, while that of recycled wood increased to 0.9 million cubic meters.

Consumption - Chips - Percent - Meters

The consumption of forest chips increased by 3 percent from 2017 to 7.4 million cubic meters.

"The use of forest chips in combined heat and power production increased by 4 percent to 4.7 million cubic meters after a four-year decrease. In heat production,...
