Founded in 1985 in Pingtung, Southern Taiwan, Shyechih Enterprise (協治企業) is one of the few recycled-material producers that vertically integrates collection, sorting, and processing — three critical stages of plastic recycling.
After 40 years of focused operation, we run 5 facilities across Southern Taiwan with 3,000 metric tons of monthly processing capacity, supplying stable, traceable PET, PP, and PE recycled materials.
We currently operate five sorting plants and one processing plant in southern Taiwan, with an average monthly throughput of 3,000 tonnes. We invest heavily in food-grade PET washing lines, laying the foundation for future Bottle-to-Bottle closed-loop applications.
