Italy: Holcim has signed a collaboration agreement with energy company Eni for the development of ENI’s magnesium silicate-based carbon utilisation technology. The reaction of the magnesium silicate with captured CO₂ emissions yields a product which Holcim hopes to use in its cement production.

Holcim Innovation Center head Edelio Bermejo said “Reaching net zero in cement manufacturing will require the deployment of carbon capture, utilisation and storage technologies at scale. ENI’s solution is very promising, and we are happy to explore its potential as it could take us all one step further on our decarbonisation journey.”

UK: Cemex UK has launched ReadyBlock Zero, a zero carbon concrete block, on the UK market. The product joins the company’s Vertua reduced-CO₂ product range. Cemex UK achieved zero carbon production by means of offsetting. It said that ReadyBlock Zero will help builders to meet the UK’s government’s Future Homes Standard, which requires a 75 – 80% CO₂ emissions reduction in all newly built homes.

Cemex’s Europe regional urbanisation solutions director of asphalt, paving and building products Carl Platt said “We have developed the UK’s first carbon neutral concrete block to help housebuilders get ahead of the game when it comes to building low carbon homes that meet and exceed government guidelines and changes to building regulations. We want to make life easier for housebuilders to make simple sustainable choices that make large scale impacts on the often complex road to net zero. Concrete blocks are the most common structural component in the construction of UK homes, so by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.”

Turkey: OYAK Cement says that it eliminated 200,000t of CO₂ emissions during 2021 through its use of US-based DataRobot’s AI software. The producer said that the technology enabled it to multiply its alternative fuel (AF) substitution rate by seven an reduce its mechanical failure prediction time by 75%. It added that the software contributed to a US$39m/yr drop in costs.

Japan: The CP Concrete Consortium has received US$80m in funding under the New Energy and Industrial Technology Development Organisation (NEDO)’s Green Innovation Funding Programme. The funding will support the consortium’s development of its Carbon Pool Concrete reduced-CO₂ concrete production technology until 2032. Hazama Ando Corporation leads the consortium along with 14 other members of the Japanese Ready-Mixed and Returned Concrete Solution Association.

Carbon Pool Concrete technology can be used in the construction of pavements, buildings and other civil engineering structures. Through comprehensive carbon life cycle evaluation, the consortium is attempting to robustly link the use of its technology with carbon market instruments and environmental and social governance infrastructure funding. Its aim is to redefine concrete as a carbon neutral material.

US: The Portland Cement Association (PCA) reports that cement consumption rose by 3.6% year-on-year in the first 11 months of 2021. Ed Sullivan, Senior Vice President and Chief Economist at the PCA, made the announcement at the World of Concrete trade fair in Las Vegas, Nevada. He also forecast that cement consumption would be driven by non-residential and public works in 2023 and 2024 as mortgage rates increased. The country is also set to spend US$1tn on new and rehabilitated infrastructure projects and this would consume 46Mt of cement over a five-year program. Over a quarter of this amount would be used on roads, bridges and resiliency structures.

The PCA’s president and chief executive officer Mike Ireland and Senior Vice President of Sustainability Rick Bohan also spoke at the event to further promote the association’s Roadmap to Carbon Neutrality.

Senegal: France-based Fives has detailed the equipment that it will supply for its construction of a new 6500t/day kiln line at SOCOCIM Industries’ Rufisque cement plant in Dakar Region. The company says that it will supply a preheater, in-line Preca calciner, kiln, TGT filter and Pillard Novaflam burner.

SOCOCIM Industries’ parent company Vicat’s chair and chief executive officer Guy Sidos said “Vicat Group renews its partnership with Fives Group through this major project of building a new line with a strong local dimension, employing local workers and contractors.” He added “This plant will eventually eliminate the use of fossil fuels, reduce our energy consumption and support Senegalese local development, making a higher quality product while doubling our production capacity.”

Switzerland: Holcim has successfully issued two sustainability-linked bonds worth US$355m and US$109m in the Swiss market. The group says that the issuances are another way in which it keeps climate action at the heart of its financing strategy. It brings the total sum raised by Holcim through sustainable financing agreements to US$7.33bn. Investors will be entitled to a higher coupon if the company does not achieve its climate objective.

Chief finance officer (CFO) Géraldine Picaud said “We are proud to be the first company to launch a sustainability-linked bond on the Swiss franc market. The bond attracted new environmental and social governance investors, demonstrating their confidence in Holcim’s financial strength, strategy and ability to deliver our sustainability targets.”

Australia: RMIT University in Melbourne, Victoria, has developed a new method of carbon capture, called the bubble column method. The method uses liquid gallium at 100 – 120°C, through which flue gas is bubbled. This activates the CO₂, leading to oxidation of the metal. The captured carbon accumulates on the surface of the pool.

Gallium is a by-product of bauxite and zinc ores mining. The United States Geological Service (USGS) has estimated its global reserves in these ores alone as 1Mt.

Project co-lead Torben Daeneke said “Turning CO₂ into a solid avoids potential issues of leakage and locks it away securely and indefinitely. Because our process does not use very high temperatures, it would be feasible to power the reaction with renewable energy.” He added “Ideally the carbon we make could be turned into a value-added product, contributing to the circular economy and enabling the carbon capture and storage (CCS) technology to pay for itself over time.”

The Australian Government plans to invest US$719m in low emissions technologies by 2050 under its Net Zero Plan.

Croatia: Volunteers from Cemex collaborated with the Agricultural and Veterans’ Cooperative Lintar and local school pupils to harvest 6.5t of olives from the site of its rehabilitated Split quarry in Split-Dalmatia. The company says that the winter crop produced 900l of olive oil.

Cemex’s Europe, Middle East and Africa corporate affairs, sustainability and environmental resources manangement vice president Andrew Spencer said “We recognise that our industry has consequences for the environment, but Cemex is working hard to actively counteract climate change and this drive is present through all aspects of our business. In our cement and aggregate quarrying operations across Europe, we restore and recultivate our sites to provide optimal conditions that are managed well to deliver for biodiversity.” He added “Our vision is of a successful, sustainable Cemex that makes a positive contribution to people and the environment.”

UK: British Precast, whose members include manufacturers of concrete masonry, paving slabs, structural sections and drainage systems, has merged with the Mineral Products Association (MPA) which represents all the UK’s cement makers, over 90% of aggregates producers and more than 70% of ready-mixed concrete suppliers. The merger is intended to give the British concrete industry a single voice, with the sector’s advocacy body, UK Concrete, lobbying on behalf of the sector on sustainability issues. It should also unite the industry behind the ‘Roadmap to Beyond Net Zero’ plan by 2050.

Alan Smith, who retires as President of British Precast, said, “British Precast has been affiliated with the MPA for the past decade and the successful relationship we have built has given our members the confidence to fully support this merger. Coming together enables the industry to operate more strategically, rejuvenating our determination to rise to the challenges of climate change and emphasise the importance of our industry in climate adaptation.”

Two new MPA product groups have been formed as a result of the merger: MPA Precast and MPA Masonry. They join existing MPA product groups including The Concrete Centre and the British Ready-mixed Concrete Association (BRMCA).
