The Perstorp Group’s emissions of volatile organic compounds primarily derive from the production plants. A number of treatment plants for catalytic combustion of atmospheric emissions are installed at Perstorp’s units, and this type of treatment technology is today the most commonly used within the Group.

During 2007, VOC emissions to air from the Perstorp Group was around 178 tons (179).

Methanol represents Perstorp’s single largest emission category of volatile organic compounds – 51 tons in 2007 (47). While a number of the Group’s plants emit small quantities of methanol, emissions during 2007 were highest at the units in Perstorp (including the storage tanks at Höganäs), Bruchhausen in Germany and Vapi in India. The second largest emission category comprises dimethyl ether – 28 tons in 2007 (32) – primarily emitted from the plants in Perstorp and Toledo, Ohio, USA.

Propylene/ethylene/propane represents the Company’s third highest emission category – 22 tons in 2007 (35) released by the plant in Stenungsund.
