UK: Heidelberg Materials subsidiary Hanson has awarded a contract to Mitsubishi Heavy Industries subsidiary MHI Engineering for installation of a planned 800,000t/yr carbon capture system at its Padeswood cement plant in Flintshire. The producer plans to store its captured CO₂ in exhausted Irish Sea natural gas fields. MHI Engineering will carry out a pre-front-end engineering design study using its Advanced KM CDR solvent-based process. The supplier developed the process jointly with fellow Japan-based company Kansai Electric Power.

The project will be MHI Engineering's third of its kind at a cement plant, following similar commissions with Lehigh Cement in Canada and Tokuyama Cement in Canada.

US: Lehigh Hanson has announced the upcoming permanent closure of its Glens Falls cement plant in northeastern New York. Times Union News has reported that the producer has extended an offer of financial and job-hunting support to the plant's 85 employees. A phased closure will commence in 2023. The company said that 'changes to the competitive landscape within the context of a global cement industry' partly informed its decision, in addition to the 'small, aging and inefficient' condition of operations at the plant. Lehigh Hanson's Mitchell, Indiana, cement plant will cover the plant's market in future.

Lehigh Hanson Northeast regional president Alex Car said "We are committed to continuing to supply our customers in the New England region. We have the available capacity to meet the current and future needs of our customers, even after the Glens Falls plant halts production." Car added "We are thankful for the dedication and efforts of our Glens Falls workforce over the years and we will work to minimise the impacts to our employees and the community as much as possible."

Canada: Lehigh Cement has initiated the administrative process to begin the use of alternative fuels (AF) in cement production at its Picton cement plant in Ontario. Under the company’s plans, the plant will substitute 200t/day of AF for coal and petcoke at the plant. Possible AF sources include excess seed from farm feed production in Ontario. The Picton cement plant previously reduced its CO₂ emissions per tonne of cement by 20% through assorted sustainability initiatives.

Picton plant manager Carsten Schraeder said that the move will support Canada’s 2030 emission reduction plan, and also take pressure off landfill sites.

US: Lehigh Hanson’s Lehigh Cement plant in Union Bridge, Maryland plans to fully switch from Ordinary Portland Cement (OPC) to Portland limestone cement (PLC) production by January 2023. It will manufacture its EcoCemPLC product. The company says that the Union Bridge plant is currently the company’s largest cement plant in North America.

The decision to move to PLC follows similar changes at the company’s Mason City plant in Iowa and three cement plants in Indiana. Lehigh Hanson produced over 2Mt of PLC in 2021 and it says it is set to double this figure in 2022.

US: Dome Technology has commissioned a 169,000t dome at Lehigh Cement's Mitchell cement plant in Indiana. The dome is equipped with three reclaim tunnels, enabling 83% live reclaim.

Dome Technology sales manager Lane Robertssaid “It’s a colossal project. It’s one of our bigger domes as far as storage capacity goes."

US: Lehigh Cement’s Mason City cement plant in Iowa has transitioned to Portland limestone cement (PLC) production. The plant will produce the company’s EcoCem brand PLC. It previously launched the cement in Canada in February 2021.

Canada: Lehigh Cement and Enbridge have announced a memorandum of understanding to collaborate on carbon storage for the integrated Edmonton cement plant in Alberta. Captured emissions will be transported via pipeline and sequestered by Enbridge. Lehigh Cement says it is developing North America’s first full-scale carbon capture, utilisation and storage (CCUS) unit for the cement industry at its Edmonton plant, with the goal of capturing approximately 0.78Mt/yr of CO₂.

Pipeline company Enbridge intends to apply to develop an open access carbon hub in the Wabamun area, west of Edmonton in conjunction with Lehigh Cement and Capital Power, as part of the Government of Alberta's Request for Full Project Proposals process. Once complete the Open Access Wabamun Carbon Hub would be among the largest integrated CCUS projects in the world. Subject to the award of carbon sequestration rights and regulatory approvals, the project could be in service as early as 2025.

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 agency alleges that the company exceeded Clean Air Act emissions limits, failed to submit required reports to the state and failed to conduct required testing of equipment. 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.

Canada: Three people, of whom two are in a serious condition, are in hospital in Toronto following an explosion at Lehigh Cement’s Picton cement plant in Prince Edward County, Ontario. The Kingston Whig Standard newspaper has reported that the individuals are believed to be external contractors who were carrying out repairs at the plant. The explosion occurred in a kiln on the morning of 7 September 2021.

The Ontario Ministry of Labour and fire services continue to investigate the incident.

US: Italy-based Bedeschi has been awarded a new order for the supply of two BED RNSH 1800/6 type apron feeders for Lehigh Cement’s integrated Mitchell plant in Indiana. The new feeders will be able to process up to 1300t/hr of crushed limestone and they will be placed in the primary and secondary crushing area to replace the old existing machines. They feature super duty design with CAT type chains and a Bedeschi super duty belt. As part of the installation Bedeschi has used a three dimensional survey to define the exact room availability in the existing plant. The new feeders will join three others at the plant that were already ordered as part of an upgrade programme for clay crushing and additive dosing. No value for the order has been disclosed.

Lehigh Cement, a subsidiary of Germany-based HeidelbergCement, resumed work on its US$600m upgrade project at the Mitchell plant in February 2021. Work on the upgrade was suspended in early 2020.
