US: LafargeHolcim US and ECOncrete Tech have launched a research and development collaboration to design and manufacture a fully structural concrete scour protection unit for offshore wind turbines. The unit’s specifications include seabed stabilisation and promotion of the growth of marine organisms. The collaboration includes a large-scale pilot project to evaluate the ecological performance of units in an offshore environment. The US/Canada Binational Industrial Research and Development (BIRD) Energy programme are funding the project, which will conclude in May 2024.

LafargeHolcim US commercial excellence vice president Josep Maset said “There are many paths to achieving our net zero commitment, and most require innovative partnerships and out-of-the-box thinking. The work we’re doing with ECOncrete Tech is a notable example of searching for solutions that enable increased use of renewable energy in an environmentally responsible way.”

US: The Portland Cement Association (PCA) has published a roadmap to carbon neutrality for the cement and concrete sectors by 2050. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.

“Cement and concrete have been pivotal in building resilient, durable and sustainable communities that enable people to live safe, productive and healthy lives via structures that withstand natural and man-made disasters,” said PCA President and chief executive officer, Michael Ireland. “The PCA is uniquely positioned to lead the industry-wide ambition to achieving carbon neutrality and enable our member companies and industry partners to continue building a better future.”

The PCA’s roadmap outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).

Notably goals include a reduction of coal and petcoke use at cement plants to 10% in 2050 from 60% at present, a clinker ratio of 75% in 2050 from 90% at present and a reduction of the CO₂ intensity of concrete of 60% by 2050. The roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO₂ emissions from cement production. However is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2.

US: The California State Senate has voted in favour of a bill to implement the US’s most advanced statutory framework for cement industry decarbonisation by 74 votes to two. The statute provides for the implementation of lifecycle CO₂ emissions reporting for cement produced in the state at an estimated cost of US$220,000/yr. The California Air Resources Board will then implement a ‘programme developed as a result of identified strategies’ at an ‘unknown but significant cost.’ The aim of the strategy will be to facilitate a 40% reduction in cement production’s CO₂ emissions between 2019 and 2030 and the attainment of net zero cement production by 2045.

US: Cemex USA has upgraded two Florida cement terminals, the Pensacola and Palm Beach terminals, at a cost of US$8m. The upgraded terminals will serve to increase Cemex USA’s cement supply to the region through marine shipments from its global operations. The Palm Beach terminal is also involved in the distribution of assorted cementitious materials including granulated blast furnace slag (GBFS) and fly ash for cement production.

USA executive vice president Matthew Wild said “Florida is growing rapidly, and Cemex’s strong network makes our company well-positioned to implement supply chain and operational enhancements to meet the high demand for building materials in Florida and beyond.” He added “On the cement side, increased demand has outpaced supply at times, and we expect our supply chain enhancements to help alleviate that issue.”

US: The US Department of Energy has selected Central Plains Cement to receive US$5m-worth of funding to realise its plans for a cryogenic carbon capture (CCC) installation at its Sugar Creek, Missouri, cement plant. Contify Energy News has reported that the system will initially have a capacity of 30t/day of CO₂, with a view to eventually capturing 95% of the plant’s flue gas’ CO₂ content. The Eagle Materials subsidiary will receive US$5m in funding from the US Department of Energy for the project. The sum is part of a raft of a total US$45m-worth of grants to help towards decarbonising heavy industry and natural gas power. Chart Industries will carry out the work.

Chart Industries CEO and President Jill Evanko said that the company’s CCC model increases cement production costs by just 24%, compared to 38% - 130% for other types of system. She added “We are delighted that public and private entities recognise Chart as a leader in carbon capture technologies and products; we view this award as well as our third quarter 2021 commercial activity as meaningful steps and accelerators toward capturing - pun intended - a significant share of our anticipated US$6bn total addressable market for carbon and direct air capture in 2030.”

The St Louis Post newspaper has reported that Holcim US’s Ste-Genevieve, Missouri, cement plant is also among facilities chosen to receive funding for carbon capture and storage (CCS) installations.

US: GCC plans to fully convert production at its 0.35Mt/yr Trident Plant in Montana to Portland Limestone Cement (PLC) in early 2022. The cement producer estimates that the plant’s production change will reduce its CO₂ emissions by almost 25,000t/yr.

“We believe that our industry must continue to provide the homes, roads and infrastructure that shape our world while, simultaneously, addressing the challenge of climate change,” said Ron Henley, president of GCC’s US division. “PLC is one piece of the puzzle to reduce greenhouse gases. Concrete made with PLC is a resilient material that easily meets the needs of our customers for generations to come.” He added that GCC signed the Global Cement and Concrete Association’s (GCCA) net zero pledge earlier in 2021.

US: Martin Marietta Materials has completed its US$2.3bn takeover of Lehigh Hanson’s West Region business. The acquisition enlarges the company’s cement assets by two new plants and related distribution terminals, as well as targeted downstream operations, in California and Arizona.

Chair, president and CEO Ward Nye said "We are pleased to complete the Lehigh West Region acquisition and welcome a talented group of new employees to the Martin Marietta team. These assets serve as a new growth platform for our continued geographic expansion and are uniquely positioned to benefit from favourable market dynamics and accelerating public and private construction activity in California and Arizona.” He added “We are confident in our ability to quickly realise the benefits of this transaction and deliver significant value creation for our shareholders, customers and employees following the same proven approach we took with our acquisitions of TXI and Bluegrass."

US: Lhoist will raise the price of its lime products by US$0.2/t for every US$0.05 rise in its natural gas costs above US$2.6/MMBtu from 1 November 2021. The producer says that the price rise reflects supply challenges and increased costs, of which energy costs have risen most significantly.

The producer said “We regret having to implement this energy surcharge, but believe it necessary in the face of these energy-related cost increases. Additionally, please note that this surcharge is independent of and in addition to 2022 price increases that will be necessary for Lhoist to keep pace with general inflationary factors impacting its cost structure.” It added “We appreciate your business and cooperation during this difficult time. If you have any questions regarding the above, feel free to contact your Lhoist sales representative.”

US: California Governor Gavin Newsom has signed a bill requiring the California Air Resources Board (CARB) to develop a plan by mid-2023 for the state’s cement producers to achieve net zero emissions of greenhouse gases by the end of 2045 at the latest. A 40% reduction compared to 2019 levels would also be required by the end of 2035 with interim targets set beforehand. CARB will also be obliged to ‘define a metric for greenhouse gas intensity,’ monitor emissions data, set a baseline to measure emissions reduction progress, evaluate measures to support market demand and financial incentives to encourage the production and use of low-carbon cement amongst other actions.

Thailand: SCG International has chosen US-based Black & Veatch to help with the acceleration of its electric vehicle uptake across hundred of sites spanning its operations, including cement. The US Trade and Development Agency has given the group a grant towards three logistics fleet electrification pilot projects.

Parent company Siam Cement Group (SCG)’s managing director Abhijit Datta said "I would like to express our sincere gratitude to USTDA as well as Black & Veatch for their support, guidance and efforts that have made this project possible."
