Waste Management, Recycling and Reuse

LITE-ON follows the ISO 14001 procedures and install full-time units to be responsible for efficiently monitoring and managing waste production by source. To achieve effective management and waste reduction, LITE-ON adopts the principles of minimum waste and maximum recycling and reusing, and selects qualified recycling service providers equipped for waste treatment. Total waste generated was 20,207 tonnes in 2019, 3,534 tonnes (14.89%) less than in 2017 base year. The amount was 2,911 tonnes (12.59%) less than in 2018. The waste intensity fell by 10.34%.

LITE-ON continues to promote source management, increase reuse of consumables and scrap, improve the design requirements for raw materials, production processes, and products, reduce material input and waste output, perform classification and management of hazardous waste from scraps, and reduce the output of untreatable hazardous waste. In addition, the company performs regular onsite audits to ensure effective waste reduction. We continue to implement reuse, optimized packaging materials, reduction at sources, and hazardous waste management throughout the production process in order to increase reuse of consumables and scrap. Acetone recyclers and explosion proof solvent recyclers are installed in all five Changzhou plants. The equipment recycles up to 60% of acetone and 90% of alcohol solutions, and reduces the output of waste organic solutions by 20,685 liters. Regarding optimized packaging materials, LITE-ON continues to improve the packaging design, uses more reusable packaging materials, extends the useful life of packaging materials, and promote recycling of waste packaging materials. Packaging materials have been reduced by 34.8% for projectors and 50% for LED streetlights. Regarding reduction at sources, LITE-ON improves the design requirements for raw materials, production processes, and products, and reduces material input and waste output. Integration and optimized design of synchronous rectification ICs have reduced use by 33.36Mpcs. Regarding hazardous waste management, LITE-ON monitors online collection and delivery of hazardous chemicals and controls entry/exit to the warehouse. Specific controls are in place to manage hazardous chemicals in the plants.

Water Resource Conservation

LITE-ON builds its water resource management system on ISO 14001 standards. In 2019, the total water consumption was 2,792,176 tonnes, and the intensity of water consumption was 17.47 m3 per NTD million. The water use was 246,941 tonnes (8.13%) lower than in 2017 base year. The total volume of wastewater discharged, based on China's Code for urban wastewater and stormwater engineering planning, is estimated at 2,373,350 tonnes.

Wastewater Treatment and Resourcization

Water consumption at LITE-ON plants was sourced 100% from the local water system (i.e. tap water) and used primarily for employees' life-sustaining needs and for plant equipment. All wastewater produced is either properly treated or discharged into water treatment plants as required by law. A small amount of industrial wastewater is treated by the wastewater treatment facilities inside the plants (by methods such as sedimentation or chemical coagulation), and discharged when the treated wastewater meet the local regulatory requirements. The discharge of water should have no significant impact on the water body. To ensure effective wastewater treatment and resourcization, LITE-ON has been adding facilities for recycling and reuse of air conditioning condensation water and RO wastewater, recycling and reuse of pure water from facilities, and rain water recycling. The total volume of water recycled in 2019 was 126,337 tonnes, which was 1.48 times more than in 2018.
