Emissions & environmental impact
Emissions to air
Several production sites have succeeded in their efforts to reduce emissions to air. At Perstorp, catalytic gas treatment has been installed for production of Di-TMP. In Stenungsund a new steam boiler was started up in the spring of 2010, which meant a cut of around 6% in emissions of nitrogen oxides.

Emissions of carbon dioxide
In 2010 Perstorp’s total emissions of carbon dioxide amounted to 806,000 (773,000) tons of which 88,000 (91,000) tons were carbon dioxide from renewable fuels. The production site at Perstorp produced 634 (554) GWh of energy, of which 241 (234) GWh, or 34 (43)%, was from renewable fuel.

In 2010 Perstorp’s production sites in Sweden delivered district heating to local municipalities and steam to other plants on the industrial site. The total amount was 254 (206) GWh.

Emissions of ozone-depleting compounds
The total amount of ozone-depleting compounds was 15.6 (15) tons. The spillage in 2010 amounted to 6.8 (2.3) tons, or 44 (15)% of the installed amount. A mistake during maintenance work at the production site in Pont-de-Claix, France, accounted for 5.9 tons of this considerable increase.
