Polyester products mainly include PET and fiber. PET products include PET bottles and packaging materials, which can be recycled and remanufactured into new polyester products, and FENC is the world leader of this technology. The main applications for polyester fiber are textiles such as apparel and interior textile. Different fibers are blended together during production. The complex composition adds to the difficulty of recycling.

In light of the fact that textile waste is under increasing public scrutiny, FENC launched the TopGreen^®ChemCycle Process development project. The goal is to develop chemical recycling and treatment technology for textile waste to address the current technological limitation of recycling only singular type of polyester textile. The goal is to turn textile waste into high-value functional textile, fulfilling the dream of circular economy using Textile to Textile (T2T).

This technology has received funding from the 2018 Taiwan Industry Innovation Platform Program (TIIP) from Industrial Development Bureau of MOEA. In addition to enhancing the core technology, FENC integrates related industries across several fields, including optical recognition, wastewater recycle and waste treatment. The company also built pilot plant to evaluate the feasibility of mass production.
