SkreenHouse Invests in Electric Calcination Pioneer Litherm

 

SkreenHouse Ventures Ltd, the innovation and investment platform of SigmaRoc, has invested ~ €1m in the €6.5 million seed financing round of Litherm Technologies GmbH ("Litherm"). Litherm is developing fully electric calcination technology that enables lime and cement to be produced without CO2-emissions.

The investment supports the development of practical solutions aimed at decarbonising the lime and construction materials industry. Technologies such as fully electric calcination, combined with built-in CO2 capture, could significantly reduce the unavoidable process emissions in lime production while remaining commercially viable.

The funding builds on existing cooperation between Litherm and industry partners, including SigmaRoc's German entity Fels-Werke, which is providing a site and material supply for the construction and operation of a pilot plant to evaluate the technology under real-world conditions.

Ludovic Emsens, Manager at SkreenHouse Ventures, commented:

"We support technologies that enable meaningful industrial decarbonisation while maintaining economic viability. Litherm's fully electric calcination process and integrated CO2 capture approach is an important step forward for the industry."

SigmaRoc continues to evaluate opportunities to support innovation across its core markets as part of its broader sustainability and value creation strategy.
