Pryme Halts Pryme One Testing After Renewed Reactor Valve Failure

Pryme B.V. ( (DE:8XG0) ) has shared an announcement.

Pryme has halted the testing program at its Pryme One plant after a renewed loss of containment at the reactor discharge valve connection, despite recent repairs intended to fix similar issues seen in December 2025 and early February 2026. The company must cool down the reactor to evaluate the root cause and carry out further repairs, and it does not expect production to restart before mid-April 2026, delaying its ramp-up plans and signaling ongoing technical challenges at its first industrial-scale facility.

The extended downtime at Pryme One may slow operational progress at a key plant that underpins Pryme’s industrial rollout strategy in chemical recycling of plastic waste. Investors and partners will be watching closely how quickly and effectively Pryme resolves the mechanical integrity issues, as the plant’s performance is central to demonstrating the scalability and reliability of its proprietary technology.
