In 2004, Stora Enso set a Group-level environmental target to reduce SO2 emissions by 15% per unit production of pulp, paper and board from 2004 levels by the end of 2009. To achieve this target, mills have to optimise their usage of fuels, adjust their process parameters, and increase their energy efficiency.
The other principle emissions to air from Stora Enso’s operations are carbon dioxide, nitrogen oxides and particulates. These emissions are mostly generated during the burning of fossil fuels to produce power and steam for pulp or papermaking processes. Wherever possible, Stora Enso’s mills use bio-fuels for energy production. Bio-fuels produce very low sulphur dioxide emissions, and also help to reduce greenhouse gas emissions from fossil fuels and conserve non-renewable fossil fuels.
Stora Enso mills widely utilise air pollution control technologies such as electrostatic precipitators to control particulate emissions, as well as state-of-the-art process controls designed to reduce emissions.
