Three heavy rare earth oxides in production, a ten-year licence with a 2031 waste deadline, and an environmental assessment still under review
The only reported producer, so far, of both light and heavy rare earths outside China
Lynas's Gebeng plant in Pahang has produced three separated heavy rare earth oxides since May 2025 — dysprosium, terbium and samarium — making it, in the most recent reporting found, the only company outside China doing so. Malaysia renewed the plant's operating licence for ten years in March 2026, to 2036, but on stricter terms: all radioactive waste generation there must stop by 2031, and a new separation facility announced in October 2025 still awaits environmental clearance.
- 3Separated heavy rare earth oxides in commercial production
- AU$180mNew heavy rare earth facility (about RM500m)
- 10 yrsLicence extension, to March 2036
- 2031Deadline to end radioactive waste generation
What Is Documented Corroborated by more than one independent report
| Standing | What | Detail |
|---|---|---|
| Confirmed | Three heavy rare earth oxides in commercial production: dysprosium (May 2025), terbium (June 2025), samarium (March 2026) | Gebeng plant, Pahang |
| Confirmed | Operating licence renewed for ten years, 3 March 2026 to 2 March 2036, under stricter conditions | Issued by the Atomic Energy Licensing Board (AELB) |
| Confirmed | All radioactive Water Leach Purification (WLP) residue must cease by 2 March 2031 | Licence condition |
| Confirmed | The permanent disposal facility at Bukit Ketam was 72% complete as of October 2025, with four storage cells already in use | Independent of the 2026 licence terms |
| Confirmed | A new heavy rare earth separation facility, about AU$180m, was announced in October 2025 | Still requires environmental clearance |
What Is Not Settled Kept apart from the confirmed record above
| Standing | What | Detail |
|---|---|---|
| Single source | A revised environmental filing reportedly implies a 16% rise in on-site radioactive residue, to about 2.55 million tonnes by March 2031 | Not repeated in other coverage found |
| Scope unclear | Whether the environmental assessment under review covers the new heavy rare earth facility itself, or only a separate increase in the plant's upstream concentrate capacity, is not stated in the reporting found | Both are part of the same wider Gebeng expansion |
| Accurate for now, not permanent | Lynas is reported as the only producer outside China of both light and heavy rare earth oxides | A comparable US facility had already been built and was awaiting its own first output as of August 2026 |

The Argument
Stricter Terms, Argued Both Ways The government's case, and its complication
Minister Chang Lih Kang has described the March 2026 renewal as carrying conditions significantly stricter than any earlier licence, and has said the licence could be revoked if Lynas fails to meet them. The government's evidence that the 2031 deadline is achievable, not aspirational, is the permanent disposal facility at Bukit Ketam: four of its storage cells were already handling waste as of October 2025. But the deadline's own compliance path complicates that confidence. The plan rests on extracting thorium from WLP residue to bring its radioactivity down from around 6 Bq/g to below 1 Bq/g — a process the government's own nuclear research agency, Nuklear Malaysia, has said typically takes seven to ten years to scale from laboratory to industrial level, against a five-year mandate. An earlier dispute over the same proposal, in 2023, saw Nuklear Malaysia state publicly that the extraction idea had originated with the agency itself, not with Lynas, after the government had described it the other way round.
- <1 Bq/gThe radioactivity WLP residue must fall below, down from about 6 Bq/g, via thorium extraction or another approved method.
- 1%Share of annual gross sales Lynas commits to Malaysian rare-earth R&D — a condition since an October 2023 licence variation, not new to 2026.
- 72%How complete the Bukit Ketam permanent disposal facility was reported as of October 2025.
Not a routine renewal
The renewal carries a fixed, non-negotiable deadline rather than the open-ended commitments of earlier licences, and Malaysia is now host to the largest rare earth separation plant outside China — which is precisely why the terms matter beyond one company. Whether the compliance path behind the 2031 deadline can move as fast as the licence requires is the question the government's own timeline concedes is tight.
What Others Add
Three Positions Company · government · environmental groups
Lynas Rare Earths
Locking in demand
- A binding letter of intent with the US Department of War, about US$96m over four years, with a US$110/kg NdPr floor price.
- An enhanced supply agreement with Japan's JARE, extended to 2038, with preferential access to Lynas's heavy rare earth output.
- Chief Executive Amanda Lacaze retired during 2026, twelve years into building the Malaysian operation; Chief Operating Officer Pol Le Roux became interim chief executive on 1 July 2026.
Malaysian Government
Pragmatic, but conditional
- Minister Chang Lih Kang: the renewal's conditions are “significantly stricter” than any earlier licence, and non-compliance could see it revoked.
- No new permanent disposal facility may be built once the current one at Bukit Ketam is complete.
Environmental Groups
Oversight, not trust
- Greenpeace Malaysia, 3 March 2026: the renewal leaves “unresolved long-standing concerns over radioactive waste management”, and Malaysia's role in the supply chain “must not come at the expense of environmental governance integrity”.
- Greenpeace Malaysia and Save Malaysia Stop Lynas had, ahead of the renewal, urged the government to instead enforce an earlier commitment to move Lynas's cracking-and-leaching step to Western Australia. The opposition campaign traces to March 2011.
Supply-Chain Context Why the position is strategic
| Item | Figure | Reading |
|---|---|---|
| China's refining share | ~90% | A figure widely repeated across industry coverage, elevating any ex-China alternative's strategic weight. |
| MP Materials (US), Dy/Tb status | Circuit complete, not yet in commercial output | Mechanically completed May 2026; as of its 13 August 2026 earnings call, commercial dysprosium/terbium output had not yet begun. |
| Malaysia's own reserve estimate | ~16.1m t nationally | A separate national resource base, not what Lynas processes: Lynas's Gebeng plant runs on concentrate imported from Mount Weld, Western Australia. |
Conclusion
A Position That Has To Be Renewed, Not Just Held What follows from the record above
Bottom line
Lynas's position — the only reported producer outside China making three separated heavy rare earth oxides — is real, but it is a lead being run, not a fact fixed in place: a comparable US facility had already been mechanically completed as of mid-2026, awaiting only its own first commercial output. The expansion behind that position rests on an environmental clearance whose exact scope is not yet clear from the reporting available, and on a waste-treatment deadline whose own government has acknowledged is tight against the technology's usual timeline. Nothing currently reported suggests either will fail; nothing currently reported confirms either will succeed on schedule.
What To Watch The nearer-term tests
- The revised environmental assessment for the Gebeng expansion, resubmitted after the Department of Environment requested changes — its outcome will show whether the new capacity, and the heavy rare earth facility that may depend on it, can proceed on the schedule Lynas has stated.
- Independent, published progress on scaling thorium extraction beyond pilot stage — the step the 2031 deadline's entire waste-treatment path depends on, and the one the government's own agency has called a seven-to-ten-year process being compressed into five.
- Whether MP Materials' Mountain Pass circuit reaches commercial dysprosium/terbium output before Lynas's position is described elsewhere as anything other than the only one of its kind.
