Emissions of greenhouse gases 2015 (2014)

Total Greenhouse Gas emissions: 410 (399) kton CO2 equivalent:

  • Scope 1 = 354 kton CO2 equivalent
    -  CO2 from renewable fuels: 106 (95) kton
    -  Other greenhouse gases (N2O, CFCs): 1.9 (2.7) kton CO2 equivalent        
  • Scope 2 = 56 kton CO2 equivalent

A significant part of Perstorp's climate impact is caused by direct emissions of carbon dioxide from burning fossil fuels, and indirectly through the consumption of purchased electricity and steam. The emission of fossil carbon dioxide has declined slightly since 2013.

Emissions of ozone-depleting substances 2015 (2014)

The total quantity of ozone-depleting substances used was 3.0 (2.1) tons. The leakage rate in 2014 was approximately 174 (304) kg.

Other air emissions 2015 (2014)

• VOC: 187 (140) tons
• Sulphur dioxide: 6 (5) tons
• Nitrogen oxides: 161 (158) tons

Perstorp's emissions of volatile hydrocarbons (VOC) are process-related and the major specific substances are dimethyl ether, propylene and methanol.

Perstorp's emissions of sulphur dioxide and nitrogen oxides come primarily from the Group's power plants.

Waste 2015 (2014)

• Total waste: 54 (54) kton
• Hazardous waste: 42 (41) kton
• Non-hazardous waste: 12 (12) kton
• Total amount of waste per ton of product: 34 (33) kg/ton of product
• Total amount of waste per ton of product put to landfill: 4.5 (5.4) kg/ton of product

Certain waste is recycled internally for energy recovery within the Perstorp Group, for example, 7460 (6330) tons of return methanol at the Perstorp site, 18600 (15975) tons of reaction mother lye at site Bruchhausen and distillation residues at site Warrington amounting to 2335 (2860) tons. By recycling these streams as an energy source, the need for additional fossil fuels is reduced.

Waterborne pollutants 2015 (2014)

• COD before treatment: 6040 (7800) tons

At the sites in Perstorp, Stenungsund and Zibo emissions are purified in internal wastewater treatment plants and others are connected to other industrial or municipal treatment plants.
