Belgium: Etex and Heidelberg Materials have joined forces on CEMLOOP XL, an industrial-scale project co-funded by the EU’s LIFE Programme that aims to revolutionise fibre cement recycling through a fully closed-loop process integrating carbon capture utilisation and storage (CCUS) technology. According to a press release by Etex, this will reduce CO₂ emissions in cement production by at least 20% and cut energy consumption in the process by 15%.

The project will combine the two company’s expertise to create a fully circular process where waste fibre cement is transformed into high-quality secondary raw material to produce low-carbon cement that will be reused in new fibre cement products. Etex, in collaboration with the Jacobs Group, is developing a recycled fibre cement paste (RFCP) process that converts waste from Etex’s production lines and the wider construction sector into reusable material and avoids landfilling. A new recycling facility in Hemiksem, near Antwerp, is under construction and scheduled for completion by mid-2026.

At Heidelberg Materials’ Lixhe cement plant in Liège, the company is implementing CCLIX, a carbonation process that treats RFCP with CO₂ captured from kiln exhaust gases. This produces carbonated RFCP (cRFCP), which regains cementitious properties and can partially replace clinker in low-carbon cement production. A dedicated carbonation reactor is set to be commissioned at Lixhe by the end of 2028.

Etex says that CEMLOOP XL will prevent 60,000t/yr of fibre cement waste, save 100,000t/yr  of raw limestone, and capture or avoid around 900kg of CO₂ for each tonne of RFCP produced. This process combines utilisation and storage in one step - the captured CO₂ becomes chemically bound within the new product, acting as a permanent CO₂ sink.

Eric Bertrand, chief innovation officer at Etex, said “By 2030, we aim for over 20% of our inputs to come from circular sources and to send zero waste to landfill. Fibre cement plays a central role in this transformation. For the first time, it will follow a fully circular journey - a milestone only made possible through strong partnerships like this with Heidelberg Materials.”

US: Çimsa has started production at its new grey cement grinding facility in Houston through its subsidiary Cimsa Americas Cement Manufacturing and Sales Corporation, according to Yatirimlar news. The plant has an annual capacity of 600,000t/yr and commanded an investment of US$82m, reportedly making Çimsa the first and only Turkish cement producer with grey cement production operations in the US.

The company, which already operates a 300,000t/yr white cement grinding plant in the country, said the new facility strengthens its position in the US market by adding grey cement production capacity.

CEO Umut Zenar said “Our goal in doing so was to transform Çimsa into a global building materials company with both geographical production diversity and a differentiated product range. During this process, we strengthened our existing operations while continuing our path with international acquisitions and new investments. With the acquisition of the Bunol factory in Valencia, Spain, which we completed in 2021, we became the world's second largest producer in the white cement market. Then, with the Mannok investment we completed in 2024, we strengthened our presence, especially in Ireland and the UK, and accelerated our transformation with the new products we added to our portfolio. Today, we are happy to launch our new investment in the USA. We have been present in the US market for a long time through exports. This new investment, which we have implemented within our US-based company, is a turning point for us. We are no longer a brand that only exports to the USA, but also a player with on-site production power. In this way, we gain logistical advantages and offer much more to our customers. We will be able to provide fast and efficient service. We also aim to increase our sales volume and strengthen our market position with our local manufacturing capabilities in the US. It will also contribute to increasing the share of our foreign currency-based revenues.”

Bolivia: The municipal government of Santa Cruz de la Sierra has signed an agreement with Itacamba Cemento to recycle thousands of end-of-life tyres (ENDTs) into alternative fuel for cement production, according to the El Deber newspaper. The initiative was implemented through the Municipal Waste Management Company (Emacruz).

Under the agreement, discarded tyres collected from landfills will be transformed into thermal energy for use in Itacamba’s cement kilns, reducing waste and fossil fuel consumption. The tyres will be incinerated at temperatures exceeding 1400°C, with monitoring and gas-capture systems employed to prevent harmful emissions.

Mayor Jhonny Fernández said “We guarantee the responsible disposal of thousands of tonnes of tyres that would otherwise cause pollution or become breeding grounds for diseases like dengue. This is our tangible contribution to a healthier environment and better quality of life for our citizens.”

Itacamba Cemento general manager Marcelo Morales said “Co-processing is a globally recognised waste management method that complies with the waste hierarchy. Our kiln enables the complete and safe destruction of non-recyclable materials.”

Japan: Austria-based UNTHA shredding technology has appointed Sun Earth as its official partner for regional sales, system design and service of its industrial shredders in Japan. The agreement expands UNTHA’s global presence to around 40 countries. The partnership responds to rising demand for environmental technologies in Japan, particularly for waste-to-energy and recycling applications. UNTHA’s XR, ZR and RS shredder models will support the production of refuse-derived fuels and the recycling of valuable materials.
