Water Resources Management

          According to the Aqueduct Water Risk Atlas of the World Resources Institute, all areas in Taiwan belong to Low – Medium (1-2). All the TSC operating bases are not set up in national or international protection areas, and the water intake is from the legal water resources authorized by the government, having no significant influence on water resources. In 2022, the amount of water intake was 10,887.18 million liters, a 2.38% decrease compared with 2021, and the water intensity decrease 7.32% compared with the previous year, mainly caused by the increase in the revenue. 

          In order to properly use water resources, TSC is committed to the enhancement of water management and wastewater recycling. TSC actively promotes the recycling and reuse of wastewater to reduce the impact of wastewater discharged on the environment, and we also continue to improve the effectiveness of water conservation to reduce the consumption of water resources. The consumption of water of 2022 was 8,975.86 million liters.

          In 2021, Big and small packages of frozen meat, small frozen packages of TSC safety pig series, meat crisps and meatballs produced by TSC were issued the water footprint verification statements by SGS. Moreover, the 50kg-packaged Refined White Sugar had passed SGS verification in 2019 and obtained product water footprint verification statement, Business water footprint, and service water footprint verification respectively. 

Wastewater Discharge

          TSC protects the environment and fulfills the corporate social responsibility. All the units of the Company have obtained the water pollution prevention and control permit and established relevant wastewater treatment procedures. Qualified testing agencies are entrusted to take samples for analysis on a regular basis, and the declaration of the inspection is also conducted on the website designated by the EPA. The effluents are discharged to the sewage system or approved water bodies legally, and the quality of discharged water is in compliance with the discharge water standards stipulated in laws and regulations for the industry. Wastewater is finally discharged into the sea and does not have major impacts on the water sources.The amount of discharged wastewater in 2022 was 1,911.32 million litters, a decrease of 4.76% compared with 2021.

Air Pollution Monitoring

          In order to comply with the environmental protection laws and regulations, TSC has formulated Key Points for Environmental Management for the Operations of Air Pollution Prevention, and also included the ISO 14001 Environmental Management Standards to establish operations, inspections and emergency response measures to ensure compliance with laws and regulations related to air pollution. Prevention of air pollution begins with the rational reduction of pollutants in the process before being emitted into the exhaust gas, and air pollution control equipment handles pollutants in the exhaust gas. Currently, the large scale (granular pollutants of pollutants reaching 10 tonnes/year, or sulfur oxide reaching 5 tonnes/ year, or volatile organic compounds reaching 5 tonnes/year) stationary pollution sources are the three sugar factories under the Sugar Business Division. The rest relatively small-scale stationary pollution sources include 2 locations of the Biotechnology Business Division, 73 locations of the Petroleum Business Division, 19 locations of Livestock Business Division, 1 location of the TSRI, and 1 location each of the Tainan and Yunchia Operation Branches. The air pollutant emissions of all units are in accordance with the emission standards and are reported regularly. TSC’s Department of Environmental Protection also makes on-site inspection from time to time.

          The actual test results of the concentration of air pollutants over the years all met the emission standards stipulated by EPA. The NOx emission intensity in 2022 decreased by 82% compared with 2021, and the SOx emission intensity in 2022 decreased by 35% compared with 2021, mainly because the operation contracts of Gangshan and Kanting Refuse Incineration Plants expired in November and December in 2021 respectively, and the operation business was terminated, leading to the reduced overall air pollutant emissions. However, the overall revenue of the company increased, resulting in a reduction in emission intensity. The air pollution control situation is shown as follows, and the emission concentrations all met legal standards.
