Greece: Titan Group has entered a strategic partnership with thyssenkrupp Polysius to advance Polysius’ meca clay technology, which aims to reduce CO₂ emissions from cement production. The collaboration was formalised through a memorandum of understanding.

The meca clay system activates alternative cementitious materials to partially replace clinker, thereby lowering emissions and energy use without affecting performance, according to the company. Titan will first implement the technology at its Patras cement plant, with pilot activities scheduled for 2026 and further rollout planned. The partnership targets the production of low-carbon cement with a clinker-to-cement ratio below 40%, compared to 93% in ordinary Portland cement.

Germany: AUMUND Fördertechnik has launched its electrified Linear Calcination Conveyor (eLCC), which enables efficient clay calcination for limestone calcined clay cement (LC3).

LC3, composed of roughly 50% clinker, 30% calcined clay, 15% limestone and 5% gypsum, can reduce CO₂ emissions by up to 40% compared to ordinary Portland cement, according to the company. The technology enhances pozzolanic reactions between limestone and calcined clay, which provides additional alumina to form carboaluminate phases, improving strength and durability while lowering clinker use. Developed in collaboration with Holcim over four years, the eLCC was tested successfully at AUMUND’s pilot demonstration unit in Rheinberg, confirming its potential to support low-carbon cement production at industrial scale.

Belgium: Carmeuse’s LEOPARD project in Aisemont has been selected for funding by the European Innovation Fund. The project aims to achieve zero-carbon lime production through a hybrid process that combines CO₂ preconcentration with membrane-based carbon capture. The system increases the CO₂ concentration in kiln flue gases prior to capture, reducing operating costs compared to conventional post-combustion methods while avoiding additional air or chemical waste emissions, according to the company. The facility will also integrate bioenergy with carbon capture and storage technologies.

Carmeuse said the project will prevent more than 70,000t/yr of CO₂ emissions and remove additional CO₂ from the atmosphere through bioenergy carbon capture and storage (BECCS). The process runs solely on electricity, supporting the company’s target of achieving net-zero emissions by 2050.

UK: N+P Group announced that investment has been approved for its new 5t/hr research and development pilot line at its Hartlepool site. The installation will separate biogenic fractions from hard-to-process waste, including municipal solid waste and material from materials recovery facilities and other processing sites. The output will be a cleaned, high-biogenic alternative fuel, with biogenic content expected to exceed 70%. N+P aims to deliver the first volumes from its facility in the first quarter of 2026.
