Södra closes the ecosystem by returning nutrients to the forest
Södra has developed a bio-ash that comprises nutrients from forest raw materials and can be produced at the company’s own mills. The material will be used to return nutrients to the forest in order to close the ecosystem and ensure long-term production capacity.When extracting raw materials from the forest we also extract nutrients. This usually only occurs to a limited degree since nutrients are primarily found in branches and needles, which are left behind on the ground. However, when branches and treetops – which are used in the production of bioenergy – are harvested, the amount of
