Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO₂ emissions by 400,000t per decade.

Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO₂ company."

Spain: Mexico-based Cemex and its venture capital subsidiary Cemex Ventures have invested in Waste to Energy Advanced Solutions (WtEnergy), an energy startup company that has developed a process to transform solid waste into synthesis gas (Syngas) for industrial purposes.

WtEnergy converts biomass and non-recyclable waste into Syngas, which can be used in the short-term as a fossil fuel alternative or be upgraded in the medium- and long-term to gases such as biomethane or pure hydrogen. Cemex intends to incorporate this energy source into its clinker and cement manufacturing process, looking to further reduce the carbon footprint of its operations. Cemex aims to increase its fossil fuel substitution rate by 20% by 2030.

Gonzalo Galindo, the president of Cemex Ventures, said, “This investment aligns with our strategy to find innovative clean fuel and energy sources for the cement industry.” He added, “We have outlined an ambitious rollout strategy across multiple operations, starting with Spain and other European countries before expanding to other international markets.”

Russia: Eurocement says that its subsidiary Peterburgcement’s Slantsy cement plant in Leningrad Oblast is undergoing an upgrade in order to co-process 100,000t/yr of alternative fuel (AF) in its cement production. The group claims that the upgrade will improve the efficiency of the 1.9Mt/yr plant and reduce its consumption of natural gas by 25%. The purported cost of the upgrade is US$1.77m.

Eurocement previously implemented the same technology at another of its cement plants in the Republic of Mordovia.

Switzerland: Switzerland-based ABB is launching the ProKiln inlet gas sampling system to help cement producers reduce the volatility associated with using higher levels of alternative fuels (AF) and allow kilns to run for longer. The product offers probe cleaning with increased mechanical strength, which includes a dual probe retraction system to ensure no sampling interruption.

The supplier says that its product uses an extractive filter in the tip of the probe which separates sample gas from the dust load to reduce problems faced with scaling of material when gathering data. It also uses two air blasters to clean the tip to maintain a sample path for analysis. A three-dimensional printed stainless steel nozzle is intended to ensure that no blockages at the tip of the probe occur and the system is mounted on a buggy running on a retractor which carries the probe in and out of the kiln allowing it to be cleaned automatically. Measuring 3m long, the gas probe is water cooled with an extractive filter placed at the sample and flow is maintained by the blasters. A cooling system also provides recirculating water for temperature control.

The ProKiln has been tested for six months at Holcim’s Lägerdorf site in Germany, a cement plant that has an AF substitution rate of over 80%.

Australia: Adbri is targeting 40% refuse derived fuel (RDF) substitution in cement production at its Birkenhead, South Australia, cement plant in 2022. By 2024, it aims to further increase RDF use to 50%. The plant used 35% RDF in its production in 2021.

Adbri says that it is Australia's only cement producer not to use coal, relying instead on a combination of RDF and gas.

Canada: St Mary’s Cement plans to apply for a licence to substitute alternative fuel (AF) for a part of its coal, gas and petcoke fuel mix. The plant previously held a two-week AF substitution trial in May 2011. CBC News has reported that the subsidiary of Votorantim Cimentos will present its plan at an evening meeting for the general public on 18 November 2021. The company says that it plans to implement similar AF arrangements to those at its Bowmanville plant, where it uses 90,000t/yr of biomass, wood from construction and demolition and non-recyclable paper and plastics.

Environmental manager Ruben Plaza said "Lower CO₂ emissions is the first consideration and, equally as important, the material has to be approved and available in sufficient quantities with a reliable and sustainable long-term supply."

Russia: Eurocement and the Toshka Centre group of companies have signed an agreement on cooperation in the use of alternative fuels (AF) at Eurocement’s cement plants. The partners signed the agreement within the framework of the Russian Environmental Operator’s nationwide Ecology project. The main area of cooperation between the parties will be the implementation of AF substitution at the cement producer’s gas-burning kiln lines. The Toshka Centre will create an AF production network to supply the producer’s operations.

Innovation and technical development vice president Sergey Demakov said, “The use of AF will allow Eurocement group to reduce natural gas consumption and show savings in fuel purchase costs at the initial stage of the project alone by 10%.”

Bolivia: Empresa Minera Industrial’s 0.1Mt/yr integrated cement plant has resumed operations across both dry lines following a fuel shortage. Tinformas has reported that a natural gas shortage caused the suspension of operations in November 2019 following an attack on a pipeline.

Uzbekistan: The government is preparing to increase the use of alternative fuels in the cement and lime industry. A draft decree intends shift local industry to meet global trends in energy consumption and away from natural has consumption, according to the Trend News Agency. The government intends to encourage the use of coal, wood briquettes and pallets, biogas and other fuels.

The Ministry of Energy, together with the Academy of Sciences and research institutes, is planning to develop energy efficiency levels for industrial gas boilers. Local gas suppliers Uzneftegazinspektsiya, Uzenergoinspektsiya and Uztransgaz will then stop supplying natural gas to non-compliant industrial users from the beginning of 2020.

Canada: The Alberta Climate Leadership Plan has allocated US$7.5m for the Lower Carbon Fuels Project at Lafarge Canada’s Exshaw cement plant. The funding is part of a total of over US$50m that will be distributed to 11 projects in the Province. Projects were selected and funded through Emissions Reduction Alberta (ERA), an organisation that accelerates the development and demonstration of emissions-reducing technologies.

“This multi-partner, multi-site research project will help Lafarge Canada better understand the environmental benefits of introducing lower-carbon fuels at the Exshaw Cement Plant. The Exshaw low-carbon fuels project will go a long way in helping us reach our ambitious corporate goal to produce 40% less net CO₂/t of cement by 2030. This support from ERA helps us move this project forward. We hope that any positive results or lessons learned will encourage others in our industry to do the same, giving this investment a greater, far-reaching impact,” said Kate Strachan, plant manager at the Lafarge Exshaw Cement Plant.

The project at Exshaw involves studying the use co-processing alternative fuels to replace the use of natural gas. Technologies for fuel handling, processing, and injection will be installed at the site to replace 50% of its natural gas use. The implementation at Exshaw will be supported by development of a waste and fuel processing facility in Calgary. Eight fuel types will be examined including construction renovation and demolition waste, non-recyclable plastic, carpet and textiles, shingles, treated wood products, wood products, rubber and tire fluff.
