Executive Summary

  • LanzaTech’s 1/10th‑scale municipal solid waste (MSW) to ethanol pilot plant in Kuji City, Japan sustained ethanol yields above guaranteed performance for more than 14 consecutive steady‑state days.
  • The facility successfully processed highly variable syngas streams with combined CO + H₂ contents as low as 40 % and H₂:CO ratios of 1.1–1.4, demonstrating robustness on challenging feedstocks.
  • The pilot, funded by a joint venture between Sekisui Chemical and INCJ plus Japanese government grants, validates the scalability and technical viability of LanzaTech’s gas‑fermentation platform for circular carbon economy applications.

Key Details

  • Plant Capacity & Scale: 1/10th commercial scale; ~400 tons ethanol per year.
  • Operational Period: Nearly four years of continuous operation since mechanical completion in April 2022.
  • Performance Milestone: Ethanol yields exceeded guaranteed values for >14 consecutive days at steady state – the most productive fermentation campaign to date at this site.
  • Syngas Conditions Handled:
  • Combined CO + H₂ content: 40 %–55 %.
  • H₂:CO ratio: 1.1–1.4.
  • Feedstock Flexibility: Demonstrated reliable fermentation of highly inhomogeneous, unsorted mixed non‑recyclable waste streams.
  • Funding Sources:
  • Investment by SBR (joint venture of Sekisui Chemical and INCJ).
  • Grants from the Japanese Ministry of Economy, Trade and Industry (METI) and the Ministry of the Environment.
  • Strategic Significance: Confirms LanzaTech’s ability to integrate its fermentation platform with existing gasifier technologies and to adapt to diverse regional waste profiles, supporting development of sustainable aviation fuel (SAF) and other low‑carbon chemicals.

Notable Quotes

“We are immensely proud of what we’ve achieved together at our Japan demonstration facility,” said Dr. Jennifer Holmgren, CEO of LanzaTech. “The results at Kuji once again demonstrate the scalability and technical viability of our fermentation platform.”
