2.3.6 Dioxins and furans
The major part of the dioxin emission owes to wood combustion in the residential
sector, mainly in wood stoves and ovens without flue gas cleaning.
Wood combustion in residential plants accounts for 64 % of the national dioxin
emission in 2010. The contribution to the total dioxin emission from the
waste sector (24 % in 2010) owes to accidental fires, especially building fires.
The emission of dioxins from energy industries owes mainly to the combustion
of biomass as wood, wood waste and to a less extend agricultural waste.

series for 1990 to 2010.
2.3.7 Hexachlorobenzene (HCB)
Stationary combustion accounts for 98 % of the estimated national hexachlorobenzene
(HCB) emission in 2010. This owes mainly to combustion of municipal
solid waste in heating and power plants. Wood combustion in households
is an important source, too, and has increased by 302 % since 1990 due
to increasing wood consumption. The HCB emission from stationary plants
has decreased 81 % since 1990 mainly due to improved flue gas cleaning in
MSW incineration plants. The emission from residential plants has increased
due to increased wood consumption in this source category.
