Ash from recovery boilers can be used to improve soils.

Stora Enso strives to use raw materials as efficiently as possible in production, and to reduce the amount of waste by finding beneficial uses for residual materials.

Residuals mainly originate from pulp and paper processes, effluent treatment, energy production and chemical recovery. Mills regularly share their best practices through regional networks, facilitated by the Environmental Technology Team within the Paper product area’s R&D group, and by Stora Enso Environment.

In 2004 the waste utilisation rate, expressed as the percentage of residuals being used for beneficial purposes, such as energy recovery and soil improvement, remained stable at 96%.

Less solid waste going to landfills

In 2004, Stora Enso approved a Group-level target to reduce the disposal of waste to landfill by 10% per unit production of pulp, paper and board by the end of 2009 from 2004 levels. Some mills have their own additional waste reduction targets. The Group-level target to reduce waste to landfill will primarily be achieved through increased raw material efficiency in the mills, and by identifying new opportunities to beneficially reuse the types of waste that currently go to landfill.
