Environmental Substance Management

Environmental Initiatives

Product Chemical Substance Management

The ROHM Group complies with all environmental laws and regulations in Japan and overseas along with customer requirements and conducts initiatives to procure materials that minimize environmental impact.
While regulations on product chemical substance management such as the EU RoHS Directive, EUREACH Regulations, and the China RoHS Directive are being further strengthened, we have established Green Procurement Standards and verified conformance to each regulation by accurately obtaining the chemical information contained in raw materials and parts.
Based on the cooperation of our business partners, we are promoting the creation of eco-friendly products, creating a management system that prevents prohibited substances from being received, used, or shipped, and supplying products that ensure worry-free use by our customers.
In addition, raw materials and parts delivered from suppliers as well as products to be shipped to customers are periodically checked for chemical substances using fluorescent X-ray analyzers installed at each production site and at ROHM's Quality Assurance Department.
