[EN07] Residues from combustion of coal for energy production
Pressures

Key message
Good

The amount of waste from coal combustion is decreasing as a result of the reduction in the use of coal for electricity generation. In 2022, the amount was 15% lower than the previous year. By far the largest source is the Šoštanj thermal power plant. Most of the waste is used as fill material in mines.
