Electric power consumption in Pennsvilledripped by 5% thanks to lower utilization levels.Fossil fuels saw a shift from natural gas to alternativefuels (solvent-based). The increased use of such alternativefuels to power the thermal emission control (TAR) systemsand to provide steam for production processes enabled afurther reduction in the external disposal of waste solvents.The increase in the use of heating oil is the result of runningenergy intensive processes (such as high temperature reactions)in production.Zofingen, today already over 50% of the wastewater canbe released into the environment as clean cooling water. The“water savings” goal for Zofingen was met.Goals 2008Zofingen and Pennsville– Updating the heating/cooling system– Stabilize energy use (cooling, air-conditioning)– Optimize savings potential of:– Installing energy-saving bulbs and motion detectors– Saving water in Zofingen– Saving nitrogen in PennsvilleThanks to updated heating / cooling systems and optimizedcooling water circulation loops, overall water consumptionwas reduced across the company by just 18%. The systematicseparation of sewage and cooling water led to a clearreduction in the amounts of wastewater to be treated. In56 <strong>Report</strong> on “Safety – Health – Environment”
