Environmental Protection Costs

Environmental protection costs

We are developing technologies to minimize the environmental impacts of our wastewater and reduce the amount of residual volatile substances in our products. We are particularly focused on developing technologies, designing equipment, and prototyping operating procedures to reduce emissions of butadiene and acrylonitrile, both toxic air pollutants, and to reduce the environmental impact of our wastewater based on such parameters as total nitrogen (TN) and chemical oxygen demand (COD). We are also working to develop eco-friendly products and innovative, energy-efficient processes.

Economic Impact

  • 画像1

We strive to use oils and other by-products arising from our production and manufacturing processes in an economically effective way by converting them to fuel, recycling them, or by other means. We also try to recycle empty drums and metal Strong Tight Economical Containers (STECs). To conserve energy, we try to capture waste heat generated by heat-intensive distillation processes.


Economic Impact Associated with Environmental Preservation Measures

Description of effects (million yen)
Cost reduction through energy savings 4
Cost reduction through waste-elimination and recovery and reuse of solvents and catalysts 1,553
Total 1,557
