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 2025, the amount of water intake was 7,230.2million liters, a 8.65% decrease compared with 2023(7,915.25 million liters), and the water intensity decrease 28.57% compared with the previous year, the main reason is that the water intake has decreased due to the lease of Dafu Farm of Huatung Operation Branch.

TSC is dedicated to the improvement of water management and wastewater recovery, proper use of water resources, reduction of wastewater discharge and enhanced water conservation effectiveness. The consumption of water of 2025 was 5,523.03 million liters. 

TSC's business units that generate waste water all have relevant wastewater treatment procedures and obtain the water pollution prevention and control permits. 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 MOENV. 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 2025 was 1,707.17 million litters, a decrease of 14.77% compared with 2024, this is mainly due to the reduction in the number of pigs at Livestock Business Division's Wanxing and Huwei farms, as well as the reduction in wastewater discharge at Nanshalun Livestock Farm due to the opening of new livestock sheds and the implementation of separate stormwater and sewage systems.

To improve the operating efficiency of the pig farming business and lower the environmental impact on the local communities, after the construction of the Dong Hai Feng Agricultural Circulation Park, TSC continues to implement the investment project of Renovation Plan of Agricultural Circulation Pig Farms, turning traditional pig housing into modern livestock park with deodorization system and sewage treatment system. In 2025, the Livestock Business Division has conducted the reuse of wastewater in the pig farms, the recovered and reuse amount of wastewater in the 11 pig farms (Wanxing, Huwei, Douliu , Haipu, Shanhua, Nan Shalun , Shilin Er, Da Xiang Yi Chang, Da Xiang Er Chang and Dong Hai Feng) totaled 397,389 metric tonnes.

TSC has a total of 16 pig farms, and all of them adopt the secondary wastewater treatment system, and qualified testing agencies are entrusted to take samples for analysis every 6 months in accordance with the Water Pollution Control Act (Wastewater discharge standards: BOD: 80 mg/L, COD: 600 mg/L, SS: 150 mg/L), and fill out animal husbandry wastewater(sewage) inspection declaration form online on the designated website of MOENV to handle the regular inspection declaration via network transmission. TSC expects that in the future, after the pig farms are renovated, new transformation opportunities will be brought to Taiwan’s livestock industry, so that it can take into account production and environmental sustainability, give the surrounding residents a fresh and green park that is odorless, allowing them to reduce their life and psychological dissatisfaction and embrace new five-sense experience.

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 metric tonnes/ year, or sulfur oxide reaching 5 metric tonnes/ year, or volatile organic compounds reaching 5 metric 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.

Based on the actual test results over the years, the concentration of air pollutants emissions also met the emission standards set by the Ministry of Environment. In 2025, the NOx and SOx emission intensities increase by 3.45% and 66.67 % respectively compared to 2024, the main reason for the increased SOx and NOx emissions is the increased sugarcane volume and processing capacity at the Huwei Sugar Refinery of the Sugar Business Division and the increased processing capacity at the Shanhua Sugar Refinery.The air pollution control situation is shown as follows, and the emission concentrations are in compliance with regulatory standards.
