According to the Statistics Finland data, twenty per cent of the wood material was tied up in paper and board, 11 per cent in sawn timber, 3 per cent in wood boards and 7 per cent in exported pulp.
The data is derived from the use and mass balances in the forest accounts compiled by the Statistics Finland.
The large proportion of fuel use is mainly due to the combustion of the forest industry’s wood wastes, such as bark and spent liquor. The share of burning has grown due to increased use of forest chippings in energy production.

In addition to wood matter, paper and board also contain diverse coating and filler substances.
