In 2020, the Group’s energy consumption data management scope covered all of the plant sites in Taiwan, the U.S., China and Vietnam. Data coverage rate is 79.7%
TECO uses tap water throughout its operations, with the sole exception of TESEN, which relies on groundwater. TESEN has a sewage treatment facility although TECO is not located in an industrial zone. Treated sewage is tested to ensure that it meets the relevant standards prior to discharge. TECO (HQ and plants) and TESEN both use tap water. TECO constantly implements various water conservation measures including installation of aerators and adoption of water saving toilets. Leaks are prevented through regular inspections.
Water Recycle performance
In 2020, the recycled water consumption quantity accounted for 15.7% of all water consumption
The recycled water consumption quantity is 76 tons/day, and it is used for 250 days per year
Casting recycled water basin capacity of 60 tons
Die casting recycled water basin capacity of 100 tons
TECO estimates that its total wastewater discharge equals 80% of the total water consumption. TESEN wastewater discharge calculations, on the other hand, are based on process wastewater amounts. The quality of wastewater discharged by TECO and its plants is inspected by qualified third-parties to ensure conformity to relevant standards. TECO plants discharge the tested wastewater to treatment facilities in their respective industrial zones. Upon proper treatment by such facilities, the quality of the discharged water meets relevant legal requirements. The casting, die casting, and painting operations at the Chungli plant site are installed with water recycling and reuse facilities, and the recycle consumption rate is approximately 11%. There are no environmental protection zones, habitats or areas with high biodiversity in the close vicinity. The impact on existing ecosystems is therefore minimal.
TECO has formulated waste storage and disposal management guidelines as part of its environmental safety management system to implement waste reduction and resource recycling in TECO and affiliated enterprises. A unified storage area has been established for waste generated by all plants. Tracking is implemented and records are created during the disposal and treatment process. Relevant records are preserved for 3 years.
Waste treatment methods employed by TECO can be divided into the following categories: Re-use, incineration, physical treatment, offshore processing, landfill. Waste electric wires and cables are shipped to Mainland China for physical treatment.
Natural Gas Usage Management
Natural gas is the main source of non-renewable energy use in the plant. TECO tracks and manages natural gas consumption of the Taiwan plant, TECO-Westinghouse, Wuxi TECO, Qingdao TECO Precision, and Wuxi TECO Precision. From natural gas fee receipts to track and manage the use of energy and corresponding carbon emissions.
Air Pollution Management
Air pollutants are mainly generated during motor production in the Chungli plant and consist mainly of Volatile Organic Compounds (VOCs). TECO has implemented improvements at the source by replacing the base coat for motors with VOC-free water-based paint. TECO has also adopted low-voc varnish.
Plant locations that generate air pollutants include TECO Chungli and TESEN. Air pollution control facilities have been established in accordance with the relevant laws and standards and dedicated personnel have been assigned to carry out operations in accordance with environmental protection-related laws. TECO is firmly committed to reducing pollutant concentrations to conform to air pollution standards. TECO and TESEN pollutant categories include SOx, NOx, PM and VOCs.
Sulfur oxide (SOX)
Nitrogen oxide (NOX)
Particulate Matter Pollution (PM)
Volatile organic compounds (VOCS)
TECO constantly assesses energy conservation and carbon reduction, waste disposal, and pollution control equipment to minimize environmental pollution caused by pollutants generated during plant operations. Relevant expenses have been incorporated into environmental expenditure items.
Definition of capital investment: For the purchase of equipment, property amount for environmental protection matters, such as the purchase of solar panels, purchase of variable-frequency equipment etc.
Definition of operating expense: Other investment amounts related to environmental protection, but excluding equipment purchase, such as air/water/waste soil/noise regulatory official fees/treatment fees; environmental monitoring fees; environmental management system maintenance fees etc.
