EcoCeres, Suzhou establish “Green Closed-Loop” SAF feedstock system

Pure-play renewables fuels producer EcoCeres said it has successfully shipped the first batch of fully-traceable waste oil – collected and transported from Suzhou Industrial Park – to its sustainable aviation fuel (SAF) plant in Zhangjiagang, Jiangsu Province, China.

This milestone marks the official launch of the “Suzhou Restaurant Waste-to-Energy City”, a closed supply chain jointly established by EcoCeres and the Suzhou Municipal Government.

The initiative allows full-traceable, closed-loop city waste oil management – from source collection to end production – transforming used cooking oil into SAF.

This delivery is the first concrete outcome of the high-level discussions held between EcoCeres and the Suzhou Municipal Government in November 2025.

Moving beyond previous fragmented efforts, the collaboration has enabled a dedicated, closed-loop feedstock system that has supported continuous operations at the Zhangjiagang SAF plant since December 2025.

The system transforms city waste oil from the Suzhou Industrial Park area from a city municipal liability into a valuable, low‑carbon feedstock. Supported by a network for collection and transportation, the waste oil is delivered directly to EcoCeres for advanced processing – completing a “waste oil–biofuel–green aviation” value chain in Suzhou.

A key competitive advantage of the system is its end‑to‑end transparency and traceability.

Leveraging EcoCeres’ self‑developed ecTrace digital platform, every batch of feedstock is tracked from its catering source through logistics to SAF production.
