The target for reducing carbon emissions at Taisun’s plants is to focus on the core “boiler” in the food industry. However, compared with 2017, Taisun did not save fuel oil use in 2018. The main reason is that the biomass boilers are undergoing annual repairs, and the standby fuel oil boilers are used to supply steam. Therefore, the amount of fuel oil has increased by 254 meters compared with last year.
Changhua County, Taiwan has been an important county and city for air pollution control since 2017. There were no violations of Taisun in 2018. The air pollutants emitted by the food industry and feed mills mainly include particulate matter, sulfur oxides (Sox), nitrogen oxides (Nox), suspended particulates (PSS) pollution, and important regulated pollution sources such as perimeter odors, which may come from Boiler combustion and wastewater treatment.
In order to effectively reduce air pollution emissions, for many years, there have been equipment to strengthen prevention of air pollution. In particular, biofuel boilers have indeed effectively reduced sulfur oxides and nitrogen oxides emissions, and can also save air pollution control costs. Other boilers also clean the boiler hearth every year to reduce carbon deposits and reduce airborne particulates. In addition, Taisun regularly replaces the parts of bag dust collectors and cyclone dust collectors to reduce airborne particulates. Taisun also pays attention to the occurrence of odors around it, and purchases ozone equipment to reduce odors and concentrations. Therefore, the annual government random inspections are effectively controlled within the regulatory standards.
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:
Taisun enterprises mainly focus on food manufacturing, and the factory area is not set in a national or international protected area. Water is taken to apply for legal use of groundwater from the government. The wastewater characteristics of the plant are mainly organic sugary wastewater, grease and suspended solids, and cannot be recycled in food factories to meet food safety requirements. In order to make wastewater comply with national standards for draining water, a professional environmental protection company is commissioned to regularly inspect the wastewater. And, in accordance with environmental protection wastewater treatment standards, the procedure is as follows: from the buffer tank → filtration → adjustment tank → primary sedimentation tank → pumping well → buffer tank → anaerobic tank → live bacteria sludge tank → final sedimentation tank → control drainage pipeline. All waste water is discharged to the discharge port after safe treatment. If there is sludge to be removed, all wastes should be registered with the waste removal and transport order, and then discharged according to the principle of waste management.
In 2018, the COD and BOD of wastewater discharged from the food factory and Beidou Ranch met the government’s emission standards. If there is an abnormal increase in monitoring, it is included in the management scope.
In 2014, Taisun Enterprises invested NT $ 10.47 million to install environmental protection equipment to effectively control environmental management. After that, the maintenance and equipment are regularly inspected and replaced every year, devoted to the management of waste water, waste and exhaust emissions, and let the environmental protection management equipment operate normally. In 2018, our environmental protection-related operating costs exceeded NT $ 2.698 million.
