Environmental Sustainability

OSE is committed to waste reduction and resource recycling by setting short- and medium-term management targets. The company aims to enhance waste classification, recycling, and treatment efficiency through institutionalized management. For 2024, the general waste recycling rate target is set above 36.7%, with a goal to increase to 37% by 2030.

In 2024, the total waste disposal volume was 2,471.2 metric tons, representing a decrease of approximately 2.5% from 2023, mainly due to a slight reduction in production scale. Waste is categorized into general (non-hazardous) waste and hazardous industrial waste based on its nature:
• General waste (including general garbage, sludge, water fertilizer, waste rubber strips, etc.) accounts for about 94% of total waste, with a recycling rate of 43.3%.
• Hazardous waste (mainly mixed hardware waste and hazardous sludge) accounts for approximately 6%, with a recycling rate of 9.6%.

OSE continues to promote waste recycling and reduction initiatives to improve overall resource reuse efficiency
