One development passed the evidence check: Avantium's first FDCA batch at a commercial-scale plant, a supply milestone for PEF. Two shortlisted research leads, a PLA/PA11 blend and a PHBV strain study, still await their evidence check.
2,5-Furandicarboxylic acid (FDCA)
Avantium's FDCA flagship plant makes its first batch
Change Avantium reports that its Delfzijl FDCA Flagship Plant produced a first FDCA batch on 28 September, after commissioning all major process units. 1
Implication PEF's key monomer moves from pilot to commercial-scale start-up; the company expects commercial sales toward the end of 2026.
Gap Design capacity, actual output, qualification results and a bounded LCA are not disclosed; ramp-up is guided at 12-24 months.

Watchlist
Avantium FDCA plant: batch-to-continuous operation and first commercial deliveries (company expects end of 2026).
Follow-up questions
What design capacity and actual output will Avantium report once the plant runs continuously?
Which system boundary and functional unit underlie Avantium's PEF footprint claims?
Editorial notes
Trial issue. Only the Avantium item is evidence-checked; nothing is signed. The technical reviewer, delivery date and distribution channel are still OPEN (G4).
Cross-issue novelty could not be checked — first issue.
September triage stopped at the 60-call budget: records still marked 'triage pending' may contain further candidates.
Evidence-checked by the build editor on 2026-10-20 from Avantium's own releases; three syndicated news reports of the same start-up were collapsed onto them. Not signed.
Issue stays 'draft' until the two remaining shortlisted leads are checked or dropped and a reviewer signs.
