Environment

As a member of society, the Optorun Group aims to contribute to global environmental conservation by complying with environmental laws and conducting environmentally conscious business activities.

Environmental Policy

We consider environmental initiatives to be a top priority and implement measures to improve the environment. By following international guidelines such as SDGs, ESG, and CSR, we share awareness of global environmental issues. In FY2024, there were no fines or penalties for environmental regulatory violations.

Environmental Philosophy

We deeply recognize the importance of environmental conservation at both regional and global levels. We evaluate environmental impact at all stages—from raw material acceptance to manufacturing and shipping—and contribute to creating an environmentally harmonious society. Through innovative products, we strive to create new social, environmental, and economic value to realize a sustainable society.

Action Guidelines

  1. １.Promote efficient resource use, energy saving, waste reduction, water conservation, pollution prevention, and environmental impact mitigation.
  2. ２.Comply with environmental legal requirements and other agreed obligations, while respecting related social expectations.
  3. ３.Establish, implement, and regularly review environmental policies to continuously improve the environmental management system and reduce resource use.
  4. ４.Educate employees to raise environmental awareness and act according to environmental policies.

Specific Initiatives

・Active procurement of environmentally conscious parts: We enforce "Green Procurement Standards" to prevent regulated hazardous substances.

・Thorough industrial wastewater treatment and water-saving: Domestic and overseas sites treat wastewater in accordance with local regulations.

・Exhaust gas treatment and management: Emissions are treated according to local regulatory standards.

・Waste reduction and recycling: Waste is properly treated and reused; certified waste disposal contractors are carefully selected.

・Product development for energy and resource savings: Contribute to a decarbonized society through energy-efficient equipment.

Energy-Saving Examples

  1. ・Oil diffusion pump (DP) optimization: PID control maintains stable heating, reducing DP power consumption by approx. 30% on 1800-size deposition systems.
  2. ・Switching to turbo molecular pumps (TMP): Replacing DP with TMP reduces pump-related power consumption by approx. 80%.

Environmental Management System Certification
No facilities are certified under ISO14001.
