(Sharecast News) - SigmaRoc said on Tuesday that its innovation and investment platform, SkreenHouse Ventures, had invested €1m in the €6.5m seed funding round of Litherm Technologies, a developer of fully electric calcination technology aimed at eliminating carbon dioxide emissions from lime and cement production.

The AIM-traded firm said Litherm is developing an electric calcination process combined with integrated CO2 capture, designed to address unavoidable process emissions in lime production while remaining commercially viable.

It said the investment formed part of its broader sustainability and value creation strategy, reflecting its focus on supporting practical decarbonisation solutions within the construction materials sector.

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

"We support technologies that enable meaningful industrial decarbonisation while maintaining economic viability," said Ludovic Emsens, manager at SkreenHouse Ventures.

"Litherm's fully electric calcination process and integrated CO2 capture approach is an important step forward for the industry."

SigmaRoc said it was continuing to evaluate further opportunities to back innovation across its core markets as it looked to advance sustainability initiatives and long-term value creation.

At 1308 GMT, shares in SigmaRoc were down 4.32% at 137.4p.
