Waste water management

All the factories have granted government approved "water pollution prevention measures" and "permit for effluent", as well as setup wastewater treatment facilities based on the prevention measures. All the wastewater 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.

Wastewater treatment and effluent status in 2018

Factory Treatment method Average COD concentration(mg/L) Average SS concentration (mg/L) Amount of effluent (M³) Recipient water body Effluent reused by others
San-Hsia Factory Factory owned wastewater treatment plant in accordance to the requirement by the regulation 17.32 8.59 7,967 Heng River None
Tayuan Plant Concentration is below the detection limit. 2.50 2,865 New Street River
Taoyuan Wires and Cables Plant Concentration is below the detection limit. 2.65 52,145 New Street River
Taoyuan 1st Plant 11.14 5.25 10,590 Old Street River
Total   - - 73,567  

Note: The effluent standard COD: 100, SS:30.



Air pollutant emissions and management

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 emissions of VOC have reduced gradually since 2015 and the emissions for NOx have slightly increased. The reason could be more diesels were consumed by RTO.

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 implemented pollutant removal facilities with higher removal efficiency, such as RTO (Regenerative Thermal Oxidizer). We have added a set of RTO at Tayuan Plant in 2018 and obtained operation permit from local authority. In 2019, we are going to change the part of treatment process from activated carbon adsorption to existing RTO in San-Hsia Factory to reduce the impact on the surrounding environment.

Waste reduction and management

Tatung's waste reduction concept is mostly from product design and process improvement to reduce the amount of industrial wastes. The wastes produced are properly classified and stored according to relevant regulations, and finally commissioned by domestic qualified treatment companies or reuse companies. Tatung audits the entrusted companies from time to time to ensure that the wastes are properly cleaned up.

▲ Tatung wastes clean up and treatment process

In 2018, Tatung produced 2,862.98 tons of industrial wastes, of which 2,832.90 tons were general industrial wastes and 30.08 tons were hazardous industrial wastes. Although the amount of wastes have been reduced by 32% in the past 5 years. However, compared with year 2017, the amount of wastes produced in 2018 was only 4.07% less which did not meet our waste reduction target of 5% per year. We will continue to work hard through green design to reduce the amount of wastes in the future. In 2018, 2,074.85 tons of wastes were reused (72.47% of total wastes). The reuse rates in the past 4 years were all above 70%.
