Air and Water Pollution Prevention

As measures to prevent air pollution, we are working to reduce emissions of air polluting substances through the adoption of fuel oil with low sulfur (S) content and conversion of fuel to liquid natural gas (LNG).
The quality of wastewater from our plants continues to meet the standards of the Water Pollution Control Law and agreements with local authorities (i.e. voluntary control standards).

Reduction of Industrial Waste

In terms of reducing the final landfill amount of industrial waste, Zeon Corporation offices continued to have zero emissions (less than 0.1% of the amount of industrial waste in 2007), which was achieved in 2011. Zeon group companies had a final landfill amount of more than 600 tons in 2007, but since 2012 that figure has been reduced to around 10 tons, or roughly 0.4% of the 2007 industrial waste amount, and can therefore be viewed as zero emissions. We will continue to promote further reductions in order to maintain 5 tons or less, as we have done at Zeon Corporation offices.
