Environmental conservation initiatives

Cataler quantitatively assesses resources such as raw materials and energy (inputs) and the products and environmental impact of its activities (outputs), and works to reduce its environmental impact not only by complying with official regulations, but also by setting voluntary targets.

Environmental impact in business

*PRTR (Pollutant Release and Transfer Register): A system for knowing what chemicals are released, and where and how much are released each year.

*Chemical oxygen demand (COD): An important indicator of organic mater. Wastewater standards apply only to wastewater discharged into sea areas and lakes.

*Biochemical oxygen demand (BOD): An indicator of the amount of organic matter that is easily decomposed by microorganisms. As a wastewater standard, it is used as a general wastewater standard.

*Suspended Solids (SS): An indicator of the amount of substances with a diameter of 2 mm or less floating or suspended in water. As a wastewater standard, it is used as a general wastewater standard.

Initiatives in product development

・Simplification of production processes (process reduction, etc.)
・Reduced use of regulated substances
・Consideration of changeover from regulated substances to alternative substances

Initiatives in material procurement

・Improving transport efficiency by changing delivery units
・Formulation of Green Procurement Guidelines
・Simplification of material procurement logistics
・Formulation of Supplier Quality Assurance Manual
・Holding regular briefing sessions for suppliers

Environmental compliance

Cataler, which restricts the use and handling of environmentally hazardous substances, has a system to confirm that raw materials do not contain substances subject to regulations. From the design stage, we confirm that the materials we purchase do not contain prohibited substances specified by the customer. Relevant laws and regulations (Law for Promotion of Chemical Substance Emission Control and Management, Industrial Safety and Health Law, etc.) are investigated and notified within the company, and measures are taken in advance. To prevent environmental accidents, the Company receives defects and complaints internally, and regular internal environmental patrols are conducted by the Environmental Protection Subcommittee and other groups. In addition, we proactively participate in environmental activities conducted by our customers in order to share and exchange information. Based on laws and regulations, prefectural and city ordinances, and agreements, we regularly report environmental data, and we also set and comply with voluntary standard values that are significantly below regulatory values.
