Environmental Care


We started to eliminate the heavy oil boilers that have been used for more than 36 years since July 2014. With the environmental awareness and the performance of occupational safety and health in the mind, we launched the energy-saving biomass boilers featuring environmental protection, safety, and specialty while creating the trust of costumes and the profit for the company. The natural “palm kernel shell” with a high calorific value is used as a substitute for fuel to produce 4500 kilo-calories of thermal energy per kilogram (stable vapor pressure/safety). The goals of environmental protection, low pollution, and high thermal energy were achieved with the new boilers. Both the carbon emission and energy cost were reduced, demonstrating the energy saving and carbon reduction effect.The success of the project encouraged more involvement of the employees to continuously transform Taisun to a company of low energy consumption and carbon emission.

The air pollutant emission of Taisun’s food and aqua feed plants mainly contained granules, sulfur oxide (Sox), nitrogen oxide (Nox), suspended particles (PSS), and surrounding odor. They might come from boiler combustion and wastewater treatment processes. We reduce and control the air pollutant emission by improving the production equipment. To improve the efficiency of the boiler combustion, we clean the boiler furnace every year to reduce accumulation of carbon and, thus, the suspended particles in the air; bag-type and cyclone dust collectors are used to reduce the suspended particles. Ozone is used to reduce the concentration of the odor. The result of the annual spot check always shows effective control within the legal standard and compliance with the law. We did not have any violation of the environmental protection regulations in 2016. 

Our waste differs by plants. The food plant needs to control the volume of garbage, sludge, and tea dust; the Beidou farm needs to manage dry excrement of pigs; and the aqua feed plant needs to manage waste feed. Recovered agricultural waste is directly transported out by the vendor and used as fertilizer. The waste management performance is described below.

We focus on control of wastewater in the aspect of water resources management. The effluent features organic wastewater with sugar, oil, and suspended particles. We do not have environmental recycling technology so far in consideration of the food safety.

We entrust professional environmental service companies to test the wastewater regularly according to the environmental protection and wastewater treatment standard. The same treatment procedures were applied from 2014 to 2016. Please refer to the previous reports for more information. Currently, we review the function of the wastewater treatment station at each plant and the concentration of the effluent according to the established standards. Though the COD and BOD of the effluent were rising in 2016, they were within the discharge level specified in the government standard.

The investment of NT$ 10.47 million in the environmental protection equipment in 2014 is very helpful to us in the improvement of the environmental management and inspection performance. In addition to the maintenance every year, the equipment is checked and upgraded on a regular basis to keep it working normally in the discharge and emission management of wastewater, waste, and waste gas. The operation cost related to the environmental protection was NT$ 2.769 million in 2016.
