Litherm Technologies Gmbh

Cement and lime are essential to modern industry. And in many cases, there’s simply no alternative. Cement is the backbone of global construction. Lime plays a critical role in steelmaking, chemicals, and environmental applications. But producing them comes with a cost: it requires extremely high temperatures, traditionally achieved by burning fossil fuels. As a result, cement and lime production together account for nearly 8% of global CO₂ emissions. A large part of these emissions comes from the kilns that traditionally are fired with fossil fuels to reach the necessary temperatures. For many years, these systems were so efficient and reliable that there was little incentive to develop climate-friendly alternatives. But the downside is clear: they emit large amounts of CO₂, and the exhaust gas contains the CO₂ in a diluted form making carbon capturing technically challenging and cost-intensive. Litherm has developed a fully electric kiln that eliminates the need for fuels entirely. It reaches the required high temperatures using climate-neutral electricity and it does something else that’s just as important: it simplifies how CO₂ is handled. The unavoidable process CO₂ doesn’t get mixed with other gases. Instead, it’s released in a concentrated stream, as a byproduct of the process itself. This makes additional CO₂ separation technology unnecessary. It’s a practical, efficient way to reduce emissions from one of the world’s most carbon-intensive industries, without changing the raw materials that manufacturers rely on today.
