About us

Joulmine GmbH & Co. KG offers an industrial solution to the wind industry’s rotor blade recycling challenge with a 44,000-ton GFRP capacity. Our thermochemical process generates low-carbon hydrogen, achieves zero emissions by capturing CO₂ for further application, and recovers fibers for reuse. Founded in 2022, Joulmine drives circular solutions.

What sets Joulmine apart is our ability to close two critical loops:

·       The Energy Cycle: By generating hydrogen as a clean fuel while utilizing renewable energy throughout our process.

·       The Resource Cycle: By ensuring that all materials, from carbon to fibers, are reused or repurposed, contributing to a fully circular economy

Joulmine operates at Technology Readiness Level (TRL) 8, meaning our technology is proven in operational environments. Our method also ensures low risk of replication due to the unique optimization of established technology. Every component is maximized for both economic and environmental efficiency, ensuring that nothing goes to waste. At Joulmine, "every element matters."

Products & Services

Engineering and System Solutions

Products:

  • Low Carbon Hydrogen (H₂):
    Produced through our thermochemical process, offering a sustainable energy source with a lower CO₂-equivalent than green hydrogen.

  • Carbon (as a raw material):
    100% of the captured CO₂ is repurposed as a valuable raw material for industrial applications.

  • Glass Fibers (as a raw material):
    Recovered glass fibers are reused in non-structural applications, virgin glass fiber production, and as fillers, enabling a circular economy.

Process:

External partners handle the decommissioning and pre-cutting of rotor blades. Once materials arrive, they undergo quality control, followed by pre-conditioning to prepare them for our advanced thermochemical process, which converts them into syngas, low-carbon hydrogen, and captured CO₂. Through final assurance, recovered fibers are repurposed, ensuring zero emissions and maximum resource efficiency.
