Environmental Activities
Contribute to the improvement of the environment around the world by correctly knowing and improving the environmental risks and impacts arising from our products and business activities.
We will strictly control chemical substances and strive to promote environmentally friendly products.
Management of Environmentally Hazardous Substances
Meltex has offices with various experimental and manufacturing functions, and chemical substances are purchased, consumed, and stored at each location.
These operations are performed in accordance with our regulations, including compliance with legal requirements, and annual audits confirm their adequacy.
In addition, we monitor the management of chemical substances, energy, and other material balances.
Manufacturing Engineering
The manufacturing process at the production plant is as follows

Energy Consumed
All of our offices monitor energy consumption on a monthly basis.
In particular, the Kumagaya factory has introduced a system that not only sets targets for energy use, but also sets an upper limit for instantaneous energy use and activates an alarm to control it so that the upper limit is not exceeded.
Chemical Consumption and Management
Substances that require special legal controls for raw materials and products are purchased, stored, and used. The overall flow and substance balance are shown here. Inventory, purchase, and shipment volumes are monitored annually.

Recycling of etchant
Meltex has been involved in the recycling of used etchant since the 1970s. We continue to provide technology to collect used etchant from our customers, recycle the refill solution and copper sulfate, respectively, and make effective use of them. This has become a recycling-oriented service model that does not generate a large amount of industrial waste from our customers and has a low environmental impact.
Environmental Protection Activities
Led by the members of "Environment Eleven," we are working on environmental load reduction activities under the life cycle-conscious environmental targets and also participating in activities such as cleanups and tree planting around our business sites.
