Emissions & environmental impact

Climate impact
During 2007, Perstorp’s total carbon dioxide emissions increased by 17% to 432 ktons (369). The increase was attributable to increased production volumes at Stenungsund and increased reporting by an additional plant, El Salto in Chile. Recalculated per ton of product, emissions have been fairly constant over time: 0.26 tons of CO2 per ton of product in 2007 against 0.25 in 2006.

Perstorp uses cooling agents of the CFC/HCFC/HFC types in its climate control and cooling facilities.

The Group’s installed HCFCs totaled approximately 1.6 tons in 2007, and the corresponding leakage of HCFCs amounted to roughly 1.1 tons during the year, primarily due to a mal­function in a cooling plant at the unit in Castellanza, Italy. Leakages also occurred at the plants in Toledo in the US, Vapi in India and Ulsan in Korea.

The Group’s installed amount of HFCs was slightly less than 1.6 tons in 2007. Leakage during the year amounted to approximately
140 kg.

Waterborne contaminants
The Perstorp Group’s main waterborne emissions come from the Group’s plants in Perstorp, Sweden, Toledo, USA, and El Salto, Chile. The plants at Perstorp and Stenungsund, Sweden, Castellanza, Italy, Vapi, India, and Ulsan, Korea, treat their emissions in wastewater treatment plants within their plant areas, while other units are connected to municipal wastewater treatment plants.

Soil & groundwater contamination
During 2002, soil and groundwater contamination was discovered at the Neopentyl glycol plant at the unit in Perstorp, and decontamination work has been under way since then. Regular follow-up inspections are performed and reported to the supervisory authority. Two of the three clean-up target values have been met, and the decontamination is expected to be completed within a year or two.

Noise
Within the Perstorp Group, external noise is in most cases no longer a problem for individual plants, which are normally covered by conditions for external noise applicable to industrial plants.
Transportation
Perstorp participates in the Forum for Sustainable Transport, a group of companies that, together with the Swedish National Road Administration, is working for the sustainable development of transportation.
