Yuantian Bio
源天生物
Yuantian Bio (源天生物) is a Tianjin-based biotech startup developing enzymatic recycling technology for waste PET plastics, founded in October 2022 by Dr. Shengpeng You, a former Tian University researcher who spent over seven years engineering PET enzyme mutants . The company operates what it describes as the world's first complete process-package design for enzymatic plastic recycling with demonstrated production line execution, having run a 300-ton-per-year rPTA pilot line in 2024 and begun construction on a 6,500-ton line in early 2026 . Its commercial model spans both direct sales of rPTA monomers to global chemical companies and co-developed products—such as enzymatically recycled yarns for fashion brands and, via a partnership with Toyota, bio-recycled materials for automotive safety components like airbags and seatbelts . The company raised a nearly 100 million yuan pre-A+ round in April 2025 with Dalton Venture participating, followed by a 100 million yuan Series A in July 2026 led by Guotai Haitong and Jinqiao Fund, with proceeds earmarked for a planned 100,000-ton production line .
