Energy Management

        Energy usage represents the primary source of Compal's greenhouse gas emissions. Each plant uses an energy KPI to keep track of energy usage, and results are reviewed and improved upon on a monthly basis. In 2016, the Company consumed 908,819,081 million joules of energy in total, which represented an intensity level of 118,521 million joules per $100-million revenue.

Use of energy by Taiwan headquarter and Chinese plants (including Kunshan, Chongqing, Chengdu and Nanjing) is explained below:


Water Resource Management
        Although Compal uses water only for general living activities and not production activities, it nevertheless implements total water resource management given the importance of water resource to global sustainability. Meanwhile, Compal continuously introduces water-efficient products and advocates good living habits in the hope of accomplishing its water-saving targets.
Our plants have been paying close attention to the use of water resources since 2011. They draw water only from the local water supply system, and used a total of 1,557,601 tons in 2016, which was equivalent to 2.15 tons per NT$1-million revenues.
With regards to the treatment of effluents from living activities, all effluents generated at Taiwan Headquarter are discharged into the public sewer system, while effluents generated by the Chinese plants are discharged into the municipal sewer system. Since all effluents are discharged into the sewer system, they do not contaminate the water source or soil. Discharge of effluents is also monitored and tested on a regular basis.
        All of Compal's plants are located inside industrial zones. The Company does not own, rent or manage any plant site located inside natural reserves or reservoirs and conducts no activity that would adversely affect biodiversity. Furthermore, none of its production and service activities pose any impact on the natural environment.


Waste Management
        In an attempt to eliminate pollution and create a clean, life-sustaining environment, Compal has been adopting proper measures to manage and treat waste at the source. In doing so, we achieved our goal to reduce waste and fulfill our corporate duty to the society with respect to waste management.
         Every department and employee in Compal's plants has been rigorously trained in environmental safety and health. No major leakage of pollutant had occurred in the past, and the Company complies with international conventions (Basel Accord) and prohibits the cross-border transportation of hazardous substances. Compal's production lines are mostly used for assembling electronic products, which are free of toxic chemicals.
         Waste from all plants is collectively treated and sorted before engaging qualified professionals for specialized re-cycling or disposal. Approximately 95% of the waste is landfilled while the other 5% is incinerated. Meanwhile, Six Sigma or reduction KPIs (such as compatibility of shared test jigs) are being used to track performance and help departments make reduction plans in every stage of the product lifecycle.
        Owing to the nature of its industry, Compal generates only a small amount of hazardous industrial waste. The waste mainly comprises: cleaning agents and alcohol used for the SMT process and re-flow oven, and tin waste generated from tin furnace; all of which are being collected by locally certified recyclers and treated in ways that comply with the law. In 2016, Compal generated 534.38 tons of hazardous industrial waste, which represented 3.13% of total waste generated.
As depicted by the following table, the Company generates two types of waste: general waste and industrial waste. General waste mainly comes from employee dormitories, whereas industrial waste is produced from plants.

   Waste comparison (no distinction of general waste and industrial waste was made for data dated before 2015)


Air Pollution Control

        In terms of air pollution control, our emissions mainly comprise the small volume of tin fume produced from the soldering process, and there is no significant emission of NOx, SOx or other hazardous gas. Compal uses active carbon-based devices to absorb and vent fumes through the air duct. Air pollutants are being monitored on a regular basis, while the Maintenance Department performs regular checks and servicing of the ventilation equipment to ensure that all test data conform with the requirements of the local environmental protection authority.



Environmental Protection Expenditure

      To protect the environment and undertake social responsibility, we save energy and reduce carbon emissions to relieve the impact of global warming. In 2016, the Company (including plants in Taiwan and China) incurred a total expense of NT$23,686,847 on repairs (excluding regular maintenance) and green R&D. No incident of severe leakage had occurred during the year. We have fulfilled our duties as a corporate citizen, and in doing so we hope to bring real benefits to the environment, for now and into the future.
