Waste water management

All the factories and subsidiaries have granted government approved "water pollution prevention measures" and "permit for effluent", as well as setup waste water treatment facilities based on the prevention measures. All the waste water treatment facilities are operated in accordance to the prevention measures and the amount and quality of the effluent are regularly tested and reported to the authorities. The rest results are all below the effluent standard. In addition, the factories are located in industrial area and/or industrial zone where do not have bio-sensitive sites nearby. Therefore the effluent from Tatung will not have significant impacts to the biodiversity of the recipient water bodies.

Air pollutant emissions and management

Tatung sets up and operates air pollutant treatment facilities in the factories in accordance to the regulation. Pollutant concentration is regularly tested and met the standard. In addition to meet emission standards, we are committed to optimize the air quality around the factories. In the past few years, we have adopted RTO and other pollutant removal facility with higher removal efficiency, and we plan to add a set of RTO to Tayuan Plant in 2018. In San-Hsia Factory we will change the part of treatment process from activated carbon adsorption to the existed RTO to reduce the impact on the surrounding environment.

The main air pollutants from the factories are NOx, SOx, and VOC. Tatung declares the amount of emissions and pays air pollution control fee to the authority. The emission the emissions of VOC have reduced gradually for the past 5 years. The emissions for NOx and Sox were slightly increased in 2017. The reason could be more fuels were consumed by RTO.

Waste reduction and management

Tatung's waste reduction concept is mostly from product design and process improvement to reduce the amount of industrial waste. The waste produced is properly classified and stored according to relevant regulations, and finally commissioned by domestic qualified treatment companies or reuse companies. Tatung will audit the entrusted companies from time to time to ensure that the waste is properly cleaned up.
In 2017, Tatung produced 2,984.54 tons of industrial waste, of which 2,930.28 tons were general industrial waste and 54.26 tons were hazardous industrial waste. Compared with the previous year, the amount of waste produced in 2017 was 13.49% less which reached our waste reduction target of 5% per year. In the past 5 years, the amount of waste has been reduced by 42%. The factories also have been working hard to recycle and/or reuse the wastes in order to minimize the impact to the environment. In 2017, 2,251.90 tons of wastes were reused(75.45% of total wastes). The reuse rates in the past 3 years were all above 70%.
