LITE-ON follows the ISO 14001 procedures and sets up a special management unit to be responsible for efficiently monitoring and managing waste production by source. To achieve effective management and waste reduction, we adopt the principles of minimum waste and maximum recycling and reusing, and selects qualified recycling service providers for waste treatment. Total waste was 27,567 tonnes in 2018, down by 3,952 tonnes (12.54%) compared to 2017. Waste intensity fell by 12.14%, reaching the target of 6% reduction by 2020 compared to 2017 ahead of schedule.
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.

LITE-ON builds its water resource management system on ISO 14001 standards. A central control system monitors factory data in real-time, and tracks water management performance at main operation sites around the world. LITE-ON is constantly trying to implement more water resource conservation measures. The intensity of water consumption by LITE-ON in 2018 was 17.16% lower than it was in 2017. The total water consumption was 17.54% lower, reaching the target of 6% water consumption decrease by 2020 ahead of schedule.
All LITE-ON operation sites draw water entirely from the local water system (i.e. tap water) and pose no significant impact on local water resources or on water accessibility of the local community. The major water demands are for plant facilities (e.g. water circulation in air conditioners, compressors, etc.) and employees' daily use. In recent years, our conservation measures were focusing on the investment in replacing traditional wet processes with dry processes, replacement and update of old cables and pipes, spot check of water outlets and routine inspection of water usage, and additional water recycling and reuse measures. LITE-ON has also incorporated water conservation measures into daily management by reinforcing water saving facilities at the plants and strengthening training to change employee water use behaviors. Meanwhile, LITE-ON makes water cost management to be part of the cost management practice by the departments for achieving more efficient water resource conservation.
In 2018, LITE-ON’s total water consumption was 3,793,619 Mᶟ and the intensity of water consumption was 19.86 Mᶟ/NTD million, decreased 17.54% Y-o-Y and 17.16% Y-o-Y respectively.
LITE-ON’s air pollution control can be divided into indoor (including production environment) air quality management and outdoor air pollution control. Preventive controls are implemented through different management means, procedure improvement, and training. In addition, flue gas desulfurization equipment, scrubbers, and high efficiency processing equipment are installed in production process for pollution control to reduce VOC emission.
LITE-ON has started implementing stronger outdoor air pollution emission controls at its plants in China since 2017. Measurement data from the plants, actual factory conditions, and local environmental policies were taken into account in the design for the comprehensive and reasonable emission treatment systems. The LITE-ON Enclosure (Guangzhou) Plant, for example, adopts a three phase control system with precipitators, UV photocatalysis, and activated carbon based absorption. The system works with an electronically controlled emission treatment system to perform the inspection, control, optimization, management, and decision making in the emission management process. The approach satisfies a range of requirements, including removal of VOC pollutants, optimized control, reduced consumption, and safety.
