Air Pollution Prevention and Control

Nan Pao controls air pollutant emissions — including volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter, and hazardous air pollutants (HAPs) — at each operating site in accordance with local regulations. Control equipment such as fume hoods, baghouse dust collectors, RTO regenerative thermal oxidizers, RCO regenerative catalytic oxidizers, and wet scrubbers are used to reduce the impact of process exhaust gas and VOCs on the environment. VOC emission intensity is tracked as the Company's primary air-quality management indicator, in line with the SASB Chemicals Industry Standard.

In 2025, Nan Pao Taiwan's VOC emissions were 63.625 metric tons, with a VOC emission intensity of 0.0096 — down approximately 10.28% from the 2023 baseline of 0.0107, achieving the reduction target. Nan Pao Taiwan will continue to promote measures such as extending VOC control to RCO, improving storage tanks and pipelines, and enhancing condensation recycling efficiency.

In 2025, the Group's VOC emissions were 70.899 metric tons, with a VOC emission intensity of 0.0041 — down approximately 10.9% from the 2023 base-year level of 0.0046, achieving the Group's target of reducing VOC emission intensity by 10% compared with 2023.
