US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NO_x emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

US: Heidelberg Materials subsidiary Mason City Cement plans to invest US$4 - 5m in upgrades to its kiln line by 2026. Upon completion, the work will enable the plant to achieve an alternative fuel (AF) substitution rate of 50%.

Heidelberg Materials' North America regional vice president of government affairs and communications David Perkins said "We want to be proactive as a company and really try to lower our carbon footprint and energy intensity, while recognising we have to be competitive." He added "We're a long-term industry on the cement side because of the investment that's required to produce it."

US: The Environment Protection Agency (EPA) has fined Lehigh Cement’s Mason City plant in Iowa US$198,000 for alleged violations of the Clean Air Act.

The EPA also determined that air pollution from the facility may affect nearby overburdened communities. Under the terms of the settlement with the EPA, Lehigh Cement is required to conduct additional air emissions testing to demonstrate ongoing compliance with the Clean Air Act.
