On our operational eco-efficiency, LITE-ON is dedicated to waste reduction, water management and air pollution control etc., and has a CSER information system under the ISO 14000 standards. Through this centralized control system, we monitor data from every manufacturing plant timely to ensure the quality of products as well as the operational eco-efficiency. LITE-ON has developed a new IT system in 2013 that accounts for expenditure for purposes such as environmental protection, safety, health, and penalties received for violations of the above. LITE-ON continued to be free of environmental violations and pollution incidents in 2016; it has never been fined for such issues.This systematic data analysis provides the foundation on which LITE-ON is able to improve its CSER performance.Besides, we are also dedicated to the reduction of GHG emission, please link to “Climate Change Strategy” for more information about it.

Waste Management and Recovery

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 34,473 tons in 2016, which was 5.70% less than the 0.17 M³/million NTD recorded in 2015.

Note: Regarding adjustments of the intensity of waste in 2014 and 2015, the original figure was 0.16 ton/NTD million, which were based on the total revenue of the group. They have since been adjusted to be based on the organization's revenue according to the environmental data disclosure and changed to 0.18 and 0.17 ton/NTD million (total waste volume unchanged) to better reflect actual conditions.

Water Management

Given the ongoing global climate change, issues concerning water resources are becoming more significant than ever, and LITE-ON has adopted a system based on ISO 14001 as a means of conserving water resources. Mainly being an assembly plant, LITE-ON does not consume significant volume of water in its production. The biggest water consumption comes from basic factory facilities (e.g. air conditioners, compressors, etc.) and employees' daily use; each accounts for approximately half of the total usage. LITE-ON's water source is entirely from the municipal water supply system, without taking from rivers, lakes or underground. It has no significant impact on local water resources or on water accessibility of the local community.

To conserve water resource, LITE-ON has established specific targets for water consumption. The most recent period began in 2014 (the base year) and aims to reduce water usage per unit revenue by 6% by 2017, along with the introduction of new water-saving facilities and management practices at each of LITE-ON's production plants and business units. In addition to making improvements to existing facilities, the water efficiency was also raised by the change of employees' water consuming behaviors. Below is the water conservation measures adopted within the company:

• Added control valves at faucets
• Changed coolant to reduce the amount of water used for air conditioning
• Rearranged water distribution for the cooling tower to reduce unevenness and wastage caused by overflow
• Adjusted toilet valves and arranged leakage inspections on a daily basis
• Installed new water-free urinals at men's toilets or reduced flush volume
• Cleaning of kitchen floors by mopping instead of intensive washing, and using water left over from washing vegetables
• Collected wastewater generated from pure water system for toilets flushing
• Turned off water valves at night and used reserve water only
• Checked water outlets and inspected water usage every day
• Collected rainwater for plants watering

In 2016, LITE-ON consumed 5,322,716M³ of water at an intensity level of 25.17M³/NTD million, which was 1.95% less than the 25.67M³/NTD million recorded in 2015.

Note: Regarding adjustments of the intensity of water in 2014 and 2015, the original figure was 23.90 and 23.52 M³/NTD million, which were based on the total revenue of the group. They have since been adjusted to be based on the organization's revenue according to the environmental data disclosure and changed to 26.35 and 25.67 M³/NTD million (total water volume unchanged) to better reflect actual conditions.

Overall, apart from minor wastage and the 10% of water used for garden irrigation, all wastewater produced by LITE-ON's plants is either properly treated by the company or discharged into water treatment plants as required by law, before releasing into receiving water body. All of the effluent lives up to the quality requirements from the governing authorities, and poses no significant impact on the natural environment. According to statistics from each plant, more than 95% of water was used for employees' life-sustaining needs and for plant equipment. LITE-ON discharged 4,790,445M³ of wastewater in 2016.

The amount of water recycled totaled 228,468 tons; most of which was recycled from cleaner production units by the advanced treatment , RO wastewater effluent recovery and rainwater recycling system.

Air Pollution Prevention

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.
