YUANTIAN BIOTECHNOLOGY (TIANJIN) CO., LTD. is a Tianjin-based biotechnology company focused on enzymatic recycling of PET plastic waste. Founded in 2022 and rooted in Tianjin University research, the company operates a closed-loop enzymatic depolymerization platform that converts waste PET—including bottles and textiles—into rPTA and rEG/MEG monomers, which are then repolymerized into recycled PET (rbPET) for packaging, textile, engineering, and optical applications.
The company has built a 300-ton-per-year rPTA demonstration/production line and has announced scale-up plans toward 5,000-ton and 10,000-ton facilities. It is positioned as an early commercial player in biological PET recycling in China and reports having obtained GRS certification for its enzymatic recycling technology. Its future priorities include enzyme optimization, feedstock diversification, larger-scale process engineering, and downstream market validation.
