Kureha strictly monitors the amount of gas emission, energy use, environmentally hazardous substances emitted in the air and water as well as waste water generated from our facilities, and makes continual effort to mitigate the negative effects on the environment.
Reduction of greenhouse gases
To prevent global warming, we are working to rationalize the use of energy at the distribution stage, in addition to efforts being made at our production sites, offices, and other places of business. Compared to the previous fiscal year, such efforts as deploying energy-saving vehicles, consolidating warehouses, and promoting eco-driving allowed us to cut CO2 emissions at the distribution stage in fiscal 2015. At our business sites, however, although energy-saving equipment was deployed and tuned for better performance, energy used for production stayed and brought higher CO2 emissions.

Reduction of Industrial waste emissions
At the Iwaki Factory, with startup in 2006 of boiler using coal fuel, the amount of waste increased in the form of coal cinders and ash, but this was recycled as raw material for cement. In the Plastic Processing Factories, reduction of waste volumes has progressed through improvement in product yields, advanced efforts with waste material separation and material recycling.

Prevention of air pollution and water contamination
During fiscal 2015, the emission of air pollutants, such as SOx and NOx, and indexes of water contamination, such as COD and BOD, were kept under a level set voluntarily by Kureha and agreed upon by local authorities. This was made possible by continually improving facilities and realizing stable operation of our manufacturing plants.
