VOCs Reduction and Foreign Odor Control

VOCs Reduction and Foreign Odor Control

Mailiao Industrial Park is the first of its kind throughout Taiwan that implements cap already fulfilled environmental assessment requirements, FPCC continues to actively make improvements to reduce the quantity of volatile organic compounds (VOCs). FPCC has invested a total of approximately NT$4.04 billion in 53 improvement projects as of 2024.

Discharge Management of VOCs

VOCs mainly come from processes (discharge channels), storage tanks, loading operations, wastewater treatment area, and grease-water separation pond, waste gas burning tower, and equipment elements. In 2024, the total production capacity was 28,323 thousand tons, and the VOCs discharge per unit product increased slightly to 0.037% compared with the previous year, which was within the reasonable fluctuation range in the past three years. In the future, we will continue to increase air pollution reduction measures (oil gas collection from inner float tank to CFB or oil gas recycling facilities) and continue to reduce VOCs discharge per unit product.

Complaints of Odor by Nearby Residents

After continuous mitigation measures to odor sources in Mailiao Industrial Park, the number of odor complaints from nearby residents has decreased year by year. There were 0 cases of odor complaints from nearby residents in 2024, and there have been no cases of odor complaints from nearby residents for several consecutive years, which shows that the overall control has achieved satisfactory results.

Monitoring of Moving Pollution Sources

To maintain the air quality in Yunlin County, we require diesel vehicles that enter Mailiao Industrial Park to submit exhaust inspection qualification documents when applying for an entry permit. If a diesel vehicle is reported by the competent authority due to its exhaust, the vendor must be re-inspected to obtain a qualification document, otherwise the vehicle will be prohibited from entering the premises. According to diesel vehicle exhaust inspection statistics of the Environmental Protection Bureau of Yunlin County, of the 195 diesel vehicles stopped on roads, 84 were inspected (the exhaust inspection was performed if the vehicle has not yet been inspected for the year) near Mailiao Industrial Park in 2024, 0 did not conform to standards; the non-conforming rate of inspections was 0%, and the non-conforming rate of stopped vehicles was 0%. Results of stopping diesel vehicles in recent years are as follows: 

Note 1: Number of diesel vehicles stopped: Refers to the number of diesel vehicles stopped and inspected by the Environmental Protection Bureau on the roadside.
Note 2: Number of vehicles inspected: Of the number of diesel vehicles stopped on the roadside, refers to the number of diesel vehicles inspected for emitting black smoke.
Note 3: Number of non-conforming vehicles: Of the number of diesel vehicles inspected, refers to the number of diesel vehicles not meeting exhaust smoke and opacity emission standards.
