The Mailiao Refinery is a core component of the massive Sixth Naphtha Cracker Complex in Yunlin County, operated by the Formosa Plastics Group. This facility stands as a major symbol of Taiwan's industrial prowess in the global petrochemical sector. The refinery was constructed on a vast expanse of reclaimed land, representing an extraordinary engineering feat that transformed offshore waters into a dense network of hundreds of chemical plants. This configuration allows for total vertical integration, managing the entire production cycle from crude oil refining to the manufacturing of final plastic products. Geographically situated on Taiwan's western coast, Mailiao features its own dedicated deep-water port to facilitate the massive import of crude and the international export of chemical derivatives. The complex plays a vital role in the national economy, supplying fuel and essential chemical feedstock to countless downstream manufacturing industries. Despite its economic significance, the facility has been the subject of environmental and safety debates within the local community. Significant investments in modern monitoring systems and emission controls are ongoing to mitigate its environmental footprint. The Mailiao complex remains one of the most productive and integrated industrial sites in Asia.
