In modern saw mills the edges of the conifer logs are directly chopped into chips. The size of these shavings varies from 10 to 50 mm and they, too, can be used for heating.  

With their cutting technique, they turn out large amounts of it. 35% of sawn round timber ends up as wood chips.
Additionally forest-wood is chopped into chips.

Chips from saw mills as well as chips from forest wood can be used for large heating systems.

Wood chips are offered with bark, without bark and in different grades of humidity (from60% down to 10%).
