US: Colorado-based energy company NovoHydrogen plans to establish a hydrogen production facility at the Ash Grove Cement plant near Durkee, Oregon. Funded by the 2021 federal Bipartisan Infrastructure Act, the plant aims to start producing hydrogen fuel by 2028, according to CEO and founder Matt McMonagle. The hydrogen produced would be stored at the plant to be used to fuel trucks and other vehicles on-site, as well as potentially being used to power the plant. The construction of the plant will reportedly create 50 jobs.

Phillip Teintze, manager at the Durkee plant, said "The Ash Grove Cement Durkee plant is active in many opportunities to decarbonise our industry. Solutions for low carbon cement manufacturing are significantly challenging in terms of processes and expense. The Durkee plant is excited to see the development of NovoHydrogen’s efforts with the Department of Energy’s Pacific Northwest Hydrogen Hub. As hydrogen becomes environmentally and economically viable, we believe our facility could act as a distribution site, and potentially utilise hydrogen as a fuel to displace traditional fossil fuels.”

Canada: Geocycle and Lafarge Canada, together with the Department of Natural Resources Canada, have opened a new low-carbon fuel plant at the Lafarge Canada Brookfield cement plant in Nova Scotia. The facility, which cost over US$7.5m and received US$2.6m in federal funding, will convert 14,000t/yr of discarded materials headed for landfill into low-carbon fuels, reducing the plant's reliance on fossil fuels and its carbon emissions by over 12,000t/yr. The materials to be repurposed include plastic and construction and demolition materials. The cement created at the facility will be used to make concrete for construction projects in the local area and is expected to create jobs for the local community.

President and CEO of Lafarge Canada (East) David Redfern said "Cement is a vital component of infrastructure projects that contribute to economic growth. By implementing sustainable and innovative solutions to reduce our environmental impact, we're serving the needs of our customers and the communities in which we operate both now and in the future. Our continued collaboration with Geocycle Canada reinforces our commitment to invest and advance circular construction in Canada."

Head of Geocycle North America Sophie Wu said "At Geocycle, our solutions are circular by design. We are happy to take another significant step in our ongoing partnership with Lafarge Canada. This is a great example of our work toward the decarbonisation of the construction industry in Canada."

India: Thiruvananthapuram city Corporation has conducted a trial run of its refuse-derived fuel (RDF) plant at Sanmathi Park, Chala. The plant processes up to 1t/day of legacy waste, which is hard to segregate, to produce fuel for cement plants. The plant processes 40kg of materials per 15-minute cycle. Currently, non-recyclable materials are sent to Tamil Nadu cement plants. The government plans to establish at least one RDF plant per district as a permanent solution.

Mexico: Regenera, a subsidiary of Cemex, has launched a pilot project at its Broquers Ambiental plant in Querétaro to transform the city’s organic waste into alternative fuel using a drying process known as ‘biosecado’. This initiative makes Querétaro the first zero waste municipality in Mexico, according to the company. The plant now processes almost 90% of the municipality’s waste, transforming over 8000t monthly into biomass to reduce the amount of material sent to landfill.

Vice president of urban solutions at Cemex Mexico, Antonio Balmori, said "This project that we started today at our Broquers Ambiental plant excites me very much because it will take the city of Querétaro to the next level in waste management, where we will seek to take advantage of 100% of the urban solid waste generated in the municipality."

Egypt: Cemex has entered an agreement with the authorities in Egypt's Gharbia province to operate the first facility of its circularity solutions business, Regenera. The company will treat over 800t/day of municipal solid waste at the facility to produce alternative fuels and compost, aiming for minimal residual waste to landfill.

"Through Regenera, Cemex seeks to conserve natural resources, reduce greenhouse gas emissions and benefit communities by promoting sustainable development and reducing the environmental impact of industrial activities," the company said.

Brazil: Votorantim Cimentos has inaugurated its first unit in Brazil for Viter, its agricultural inputs business, and Verdera, its sustainable waste management business. Located in Itaperuçu, the unit comprises a new Verdera waste crushing plant and an agricultural limestone production line for Viter. This initiative is part of a US$785m investment programme.

Verdera's Itaperuçu facility has a capacity of 48,000t/yr, tripling its previous capability, and is equipped with technology for sustainable waste treatment. The waste processed at the plant will be converted into clean energy for cement production at Votorantim's plant in Rio Branco do Sul, using co-processing technology developed by Votorantim in Brazil in 1991. Viter's new line will increase agricultural limestone production in Paraná. The Itaperuçu plant, along with the existing Rio Branco do Sul unit, brings Viter's total capacity to 1.5Mt/yr of agricultural limestone in Paraná. The new plant features filters for emission control and utilises biomass as a renewable energy source.

Mexico: Cemex said in its Integrated Report 2023 that its alternative fuel (AF) substitution rate rose to 37% in 2023. The group attributed the rise to its deployment of hydrogen injection technology.

Cemex said “We continued our global roll-out of hydrogen injection technology, and it's now used in half of our cement plants. In Mexico alone, we made sizeable investments installing new hydrogen units and plan to continue scaling hydrogen use in our operations worldwide.”

India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.

The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.

Spain: Cemex España plans to install a new tertiary mill in its Alicante cement plant’s refuse-derived fuel (RDF) line. The project, called Molentis, is scheduled for completion in early 2025 and will cost €6m. The Molentis upgrade will help the Alicante cement plant to raise its RDF substitution rate by 8%, according to the producer. This in turn will reduce its CO₂ emissions by 6700t/yr. The Spanish Ministry of Industry, Energy and Tourism granted €4.4m toward the project to Cemex España under its Innovation and Sustainability Plan.

Cemex España director of operations Benjamín Cabrera said "Molentis will enable us to advance towards climate neutrality and position the Alicante factory at the forefront of new technologies in the decarbonised industry."

France: Vicat aims to process 100% alternative fuels (AF) in its fuel mix across all cement plants in France by 2025. The L'Est Républicain newspaper has reported that the producer recorded a substitution rate of 66% in France in 2022, and of 95% at its Xeuilley cement plant in Meurthe-et-Moselle in the same year.
