From used cooking oil to jet fuel: Haixin Energy helps land China's first fully localized closed-loop SAF demo
On August 19, sustainable aviation fuel (SAF) produced exclusively by Haixin Energy (300072.SZ) was uplifted at Beijing Capital International Airport onto a Beijing–Brussels flight. The SAF was refined from waste cooking oil collected in the Beijing region — from outlets including KFC and McDonald's — via standardized sealed transport by CNAF (中国航油) and 中京征和, processed by Haixin Energy, blended and uplifted by CNAF at the airport, with carbon emission reduction rights registered and traded on the Anchor Trace platform built by 民航二所 and CNAF. It is the first case in China where the entire chain — local waste oil collection, local refining, local uplift and local carbon-right settlement — was closed within a single region (Beijing), described as a replicable "Haixin model" for a fully localized SAF closed loop. Haixin had already supplied its first SAF batch to Beijing Daxing and Chengdu Shuangliu airports in April 2025; its SAF now covers both of Beijing's hub airports.
