Energy self-sufficiency
Altri has developed an integrated approach to the forest, maximising the efficient use of this resource. Efficiency means that we care about sustainability and forest development. The forest is our main asset.
Our goal is to achieve energy efficiency. The forest is a huge source of live, clean energy. The pulp production process provides us with two methods of producing renewable energy: cogeneration and biomass .
Pulp and paper – value chain
The pulping process produces a waste stream of spent pulping liquor. Pulp mills burn the pulping liquor to recover and recycle the chemicals used in the pulping process. These chemical recovery boilers supply pulp mills with process steam and cogenerate the steam and electricity.
Forest biomass results from tree tops, limbs and cull material left over from logging activity. The forest biomass is burned in a biomass-fire boiler that transfers the heat from combustion into steam that is used to produce electricity.
