OTC's environmental management system is designed to ensure that all aspects of its business activities are environmentally friendly.
As part of this, OTC is continuously working to improve energy efficiency and the effective use of waste heat, water and resources, as well as the recycling of by-products.
As a means of reducing environmental impact, OTC promotes the recycling of waste. In particular, OTC recycles materials that would have a significant environmental impact if disposed of as waste, thereby reducing the environmental impact.
