Bringing recycled materials back into the supply chain

Since 1985, Shyechih has focused on supplying recycled materials, specializing in PET, PP, and PE collection, sorting, and processing. Through our vertically integrated 'collection–sorting–processing' flow, we deliver traceable, scalable supply of high-quality recycled plastics — bringing recycled materials back into the supply chain for the manufacturing industry.

Why

Shye Chih

選擇協治的三大理由

Shyechih's edge: process control and technical depth

1

Integrated control from collection to processing (vertical integration)

Vertical integration — one of the few in Taiwan that controls both collection and processing in-house, ensuring quality from source to shipment.

2

Technology-driven quality consistency (NIR × AI × multi-stage washing)

3,000 metric tons monthly processing capacity across 5 facilities in Southern Taiwan.

3

Supply stability backed by 3,000 tonnes/month processing capacity

NIR spectroscopy + AI vision + robotic arm — three-layer sorting for precision and consistency.
