LITE-ON's environmental expenditures were NT$392 million, or 0.20% of the total revenue, in 2017. The figure was 30% higher than it was (NT$301 million) in 2016. Moreover, LITE-ON did not incur any financial compensation or losses arising from major environmental pollution related incidents**. Environmental expenditures count data from large production facilities, including those in Taiwan, China, and Thailand.
** The definition of major environmental violations is based on the regulation of “Taiwan Stock Exchange Corporation Procedures for Verification and Disclosure of Material Information of Companies with Listed Securities”
LITE-ON reduced waste generation and elevate waste recycling with great effort. It proved to have a significant successful outcome.
Waste Source Management
Waste reduction management of LITE-ON mainly focuses on source management, and these sources are categorized as employee activity waste and manufacturing waste. Employee waste management therefore must occur through education and training accompanied by the employee code of conduct that effectively enhances waste sorting as well as reductions so that resources usability and values are increased. Manufacturing waste management mainly takes the form of packaging optimization and reduction of proportion of hazardous substances.
Centralized Storage Management
The centralized waste disposal is intended to optimize classification and upgrade safety. The various operations centers centralize the waste so the source and output of waste are strictly controlled by dedicated unit to manage waste disposal. Meanwhile, LITE-ON also work with recycling firms to increase the resource recovery and achieve the ultimate objective of zero waste.
Effective Treatment and Traceability
The output waste are handled by external professional firms who are legally qualified with the best available technology of waste treatment, and LITE-ON perform random checks to ensure that handling procedures are appropriate as well as waste disposal are well managed.
The three types of waste aggregated to a sum of 31,519 tonnes in 2017, which was 8.65% decrease compared to 34,473 tonnes generation in 2016, and 14.6% dropped compared with 2014 base year. The waste intensity decreased by 6.9%, compared with 2014, which had met our expectation. LITE-ON will continue to implement its waste management and recycling, and conduct regular on-site audits, to achieve our new target that reduces absolute waste generation by 6% by 2020 compared to 2017.
LITE-ON has adopted its water resource management system on ISO 14001 standards and use a central control system to monitor water discharge data in real-time, and tracks water management performance at major operation sites around the world. In 2017, LITE-ON continue to implement water resource conservation measures and lead to the intensity of water consumption was 9.10% lower than it was in 2014, and met the target in 2017.
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 incorporate 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 the part of the cost management practice by the departments for achieving more efficient water resource conservation.
In 2017, the total water consumption was 4,600,317 mᶟ and the intensity of water consumption was 23.96 mᶟ per million NTD, which were 13.57% and 4.82%, respectively, lower than the figures in 2016. Compared to 2014 (baseline year), the total water consumption fell by 16.56%, and the intensity of water consumption fell by 9.10%. In 2017, a total of 243,199 tons, or 5.66% of total consumption, of water were recycled. The figure was 10.87 times higher than that in 2014, and was attributed to the addition of recycling and reuse of air conditioning condensation water and RO wastewater, recycling and reuse of pure water from production workshop facilities, and rainwater harvesting. LITE-ON will continue to refine its water resource management system, implement water saving measures, and execute water recycling and reuse to achieve our new target that reduces absolute water consumption by 6% by 2020 compared to 2017.
LITE-ON's production activities mainly involve product fabrication, which produces relatively less air pollution when compared to other energy-intensive electronic manufacturers. LITE-ON is not regulated by law to apply for, measure or report stationary sources of air pollution in any of its operational locations. Emergency power generators and canteen are its main sources of air pollution. Each plant has its own environmental management system in place to prevent possible sources of air pollution, despite the fact that air pollutants produced by these plants do not pose any significant environmental aspects. In terms of prevention measures, LITE-ON has conducted air pollution control integrating indoor air quality management (including the operating environment) and outdoor pollution control. Below is a combination of management practices, procedure improvements, and enhanced training adopted to improve workplace quality and to reduce the volume of air pollutants emitted into the environment.
Each plant site has followed ISO 14001 standards and implemented prevention guidelines for the various sources of air pollution (equipment, facilities, etc). Each equipment is properly serviced and maintained, and inspected by designated departments on a regular basis. In the event that air pollution cannot be immediately controlled, LITE-ON will execute emergency response procedures to identify the cause and contain pollution within normal levels.
