Environmental Care

HOME ESG PERFORMANCE Environmental Care
In July 2014, the food factory introduced biomass fuel boilers to replace traditional heavy oil fuel boilers. Over the years, the problem of air pollution has been effectively reduced, and it can indeed reduce energy costs and balance production and carbon reduction. In 2020, Taisun did not save fuel oil. The main reason was that the main equipment of the biomass boiler was repaired and the steam was supplied by a spare oil-fired boiler. Therefore, an increase of 192 metric tons of fuel oil, an increase of about 596 metric tons of CO2 emissions.
 
If we take 2013 as the benchmark (without using biomass boilers), heavy oil will be used at 639 kilograms in 2020, and the difference in carbon reduction will be 5,425 tons, which shows that the function of biomass boilers has important benefits for Taisun’s carbon reduction.

At our food factory, palm kernel shells have been used since 2014. We have also switched to wood pellet biomass fuels made from pruned roadside branches or recycled agricultural and forestry waste including driftwood in 2018. As a means to meet higher standards of air pollution emissions, we also began to use fuel made from pelletized log shaving to reduce the generation of slag and dioxins in 2020. By making efforts to recycle and reuse, we at the same time reduce CO2 emissions which is beneficial to the environment. With the use of pure wood pellets for raw materials, we further improved the combustion rate. The slag output was significantly reduced by 65.57 tons, or 48%. 

In order to cooperate with the government to reduce the pollution from factory boiler flues, the aquatic feed factory installed a boiler scrubber in October 2017 to allow the emitted suspended particulates and sulfur oxides to comply with regulations. In addition, the boiler of the second plant of Taizhong Foods was also changed to use natural gas as fuel in September 2019, and the aquatic product plant also replaced the boiler fuel in November 2019. Regular inspections were carried out in December 2019, and the results met the new regulatory emission standards; the combustion efficiency was also increased from 83% to 91.7%. Furthermore, through the manufacturer’s assistance in monthly testing of combustion efficiency and emission gas monitoring, this will greatly reduce the pollution caused by boiler combustion emissions. In line with the EPA’s stationary source emission standard amended on July 1, 2020, our food factory also began to use the light cracking oil of Formosa Plastics Group since March 2020. Although such method is only for short-term, it required no equipment replacement to meet the air pollution standard.

The waste of Taisun Enterprise varies from factory to factory. The main items controlled in the food factory are the amount of garbage, sludge and tea residues, the management of dry pig manure on the Beidou Ranch, and the management of waste feed in aquatic plants. Manufacturers ship directly for fertilizer use. The waste management performance is as follows:

Food factory water
 
The most important raw material of the food factory is groundwater as the main water source. As the groundwater treatment facilities have been in operation for more than 30 years, some of the equipment has gradually become insufficient. Therefore, a new raw water treatment plant was built through the project engineering model and opened in March 2020. In addition to improving the quality and efficiency of raw water treatment, the metering equipment and water-saving benefits have also been significantly improved. In addition, 6 finished barrels and CIP systems were added to the IP line to fully apply the deployment and pre-sterilization system to improve the CIP cleaning efficiency and increase the production line flexibility, which has significant benefits in improving the use of water resources. Compared with 2019 The water consumption per tank is reduced by an average of 10L, a drop of 11%. The second section of the cooling water recycling project is scheduled to be carried out on the Babao Line in 2021, which is estimated to be effective in saving

Wastewater discharge management
 
Taishan enterprises are mainly engaged in food manufacturing, and their factories are not set up in national or international protected areas. They draw water to apply to the government for authorization to use groundwater legally. The wastewater characteristics of the factory are mainly organic sugar-containing wastewater, grease and suspended solids, and cannot be recycled in the food factory to meet food safety requirements. In order to make the wastewater meet the national discharge water standards, a professional environmental protection company is entrusted to regularly inspect the wastewater. And in compliance with environmental wastewater treatment standards, the procedure is as follows: from buffer tank → filtration → adjustment tank → primary sedimentation tank → pumping well → buffer tank → anaerobic tank → viable sludge tank → final sedimentation tank → controlled discharge pipeline. All waste water is safely treated before it flows to the discharge outlet. If there is sludge that needs to be cleaned up, it will be shipped out for treatment in accordance with the principles of waste management after applying for registration with the waste removal bill.
 
In 2020, the COD and BOD emissions of wastewater from food factories and Beidou Ranch are in line with government emission standards. If there is an abnormal increase in monitoring, it will be included in the scope of management.
 
 

Environmental investment

1. Food factory
 
Taishan Enterprise implements environmental management inspections and invests a large amount of funds in environmental protection equipment, engaged in the operation, maintenance and improvement of various pollution prevention equipment such as waste water, waste and exhaust gas. In 2020, our environmental-related operating costs are NT$4.04 million.
