Legal Compliance Check

Properly Comply With Safety and Environmental Laws and Regulations.

We have a system of checks to ensure compliance with laws and regulations, such as setting annual plans, conducting fire drills, checking the management of harmful substances, analyzing wastewater and soil, and measuring the environment for odors, noise, and dust by an outside organization.

Green Purchasing

Thoroughly Promote Procurement With Low Environmental Impact, Both Internally and Externally

Following our environmental policy, we established the Green Procurement Guidelines in 2009.
To procure materials and services that have less of an environmental impact, we ask our suppliers to understand these guidelines and cooperate with us in surveys on the environment and quality.

Zero Emissions

Toward the Realization of a Recycling-Oriented Society That Produces No Waste

Zero Emissions means reducing the final disposal (landfill disposal) of waste generated from production activities to zero through recycling and other methods.
At our Toki, Yamanota, Naoetsu, and Kasugayama factories, we have achieved zero emissions by recycling more than 95% of the total amount of waste (excluding general combustible materials).

MARUWA's Material Recycling

Ceramic production begins with the input of raw materials. During the production process sludge and fired ceramic products are produced, but if they are sent directly to a disposal site, they have to be thrown away as waste. Therefore, we asked ourselves, "How can we bring them back to life as materials?" We promoted material recycling by separating the materials as much as possible. As a result, sludge is used as soil for gardening, and calcined products are used as raw materials for concrete blocks.

RoHS Compliant Products

MARUWA's EMC countermeasure parts are RoHS compliant products.
The Restriction of Hazardous Substances Directive (RoHS) is a directive enforced in the European Union (EU) that prohibits the use of environmentally hazardous substances. MARUWA complies with public laws and regulations, including the RoHS Directive and our customers' environmental requirements.
