As a plant that manufactures plastic and metal products, with our corporate philosophy at front of mind, Miraial recognizes the importance of environmental protection. We have formulated the following Environmental Policy to reduce our environmental footprint and for all employees to strive to protect the environment.

Reducing the environmental footprint of our products

To reduce waste and to conserve resources, we will pursue the design and development of products that are long-lasting and that can be re-used or recycled and products that use fewer raw materials to produce.

Promoting resource-saving and energy-saving activities

We will pursue the reduction of waste plastic and metal emissions and their recycling.
We will also pursue energy-saving activities in the electricity used by our production and ancillary equipment, in our efforts to reduce our environmental footprint and prevent environmental pollution.

Compliance with environmental laws and regulations
