US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant. Holcim US partner Geocycle will collect, pre-process and deliver the tyres to the new facility.
Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."

Canada: Lafarge Canada will receive a supply of 300t/yr of sewage sludge solids from Capital Regional District (CRD) to mix in topsoil used in rehabilitation at its former Cassidy aggregates quarry in British Columbia. The Victoria Times Colonist newspaper has reported that CRD had held a supply contract to provide sewage sludge solids to Lafarge Canada for use as alternative fuel (AF) at its Richmond cement plant. The cement plant suspended its operations for ‘most of 2022’ and throughout the first five months of 2023. British Columbian law requires sewage sludge solids to be used in beneficial applications.
The district council of CRD says that it expects the Richmond cement plant to resume receiving deliveries of its sewage sludge solids in mid-June 2023.

Argentina: Geocycle has commissioned the new Line 2 of its Piedra Blanca waste management plant, Norte En Linea News has reported. The facility will now process 100,000t/yr of waste. Geocycle will supply the remaining 45% fraction of unsorted waste after processing to Holcim Argentina's Malagueño cement plant for use as refuse-derived fuel (RDF). By diverting non-recyclable waste from incineration, Geocycle says that the new line will eliminate 25,000t/yr of CO2 emissions.
Continental Cement orders alternative fuels system from FLSmidth

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 NOx 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.
