UK: Ecocem has reported the successful delivery of the first batch of its Exegy ultra-low CO2 concrete at the site of the upcoming EcoPark South waste management hub at Edmonton EcoPark in London. Infrastructure construction company Taylor Woodrow carried out the work. Ecocem says that Taylor Woodrow used Ecocem Ultra concrete from the new Exegy range, reducing the carbon footprint of the project’s concrete by 70%.

Ecocem says that it has secured contracts for the supply of Ecocem Ultra concrete to the sites of the upcoming Grand Paris Express transport link and Paris Athletes’ Village in Paris in Paris, France.

Montenegro: State-owned energy supplier Elektroprivreda Crne Gore (EPCG) has proposed the gradual shutdown of its Pljevlja coal-fired plant and its replacement with a new cement plant. The company said that such a plant would eliminate Montenegro’s 750,000 – 800,000t/yr of cement imports.

The first stage of the Pljevlja power plant’s shutdown will only commence once a replacement power facility is online. Currently, the plant supplies 40% of the country’s energy. Its closure is part of Montenegro’s plan to accede to the EU as soon as 2025.

Mexico: Cemex’s total dispatches of its Vertua reduced-CO₂ concrete in Mexico reached 284,000t in 2021. After launching the product in its home country on 8 December 2020, the company supplied it to 3820 sites throughout 2021. Cemex says that it enters 2022 with 1580 orders outstanding.

Switzerland/Germany: Holcim has announced the launch of a strategic partnership with inductive charging technology developer Magment to test and commercialise magnetisable concrete technology for use in roads. The technology will power and charge electric vehicles as they drive on roads fitted with Magment. Another possible application is in industrial floors, to charge robots and forklifts.

Holcim’s Global Innovation Center head Edelio Bermejo said: “At Holcim we are innovating to put concrete at the centre of our world’s transition to net-zero. With Magment, we are excited to be developing concrete solutions to accelerate electric mobility. Partnering with start-ups all over the world, we are constantly pushing the boundaries of innovation to lead the way in sustainability.”

UK: Building materials group Ibstock has announced its commitment to achieving a 40% CO₂ emissions reduction by 2030 and carbon neutrality by 2040. The commitment covers scope 1 and 2 emissions, building on the company’s existing sustainability roadmap commitments to create a framework of targets and critical milestones. Ibstock says that these will include investment in more efficient production processes and in high quality environmental projects to offset residual carbon. Additionally, it plans to develop a strategy to reduce indirect scope 3 CO₂ emissions in 2022. It will publish full details of all targets in its 2021 full-year results in March 2022.

During 2021, Ibstock invested Euro138m in the construction of two net zero facilities in West Midlands and West Yorkshire and procured 100% of its electricity from renewable sources. Ibstock is the parent company of Ibstock Concrete, which produces concrete roofing, walling, flooring and lintels at 14 sites across the UK.

Saudi Arabia: Qassim Cement has entered into a preliminary agreement with China-based Chengdu Design & Research Institute of Building Materials Industry (CDI) for the engineering, supply and construction of a cement mill at its integrated Buraydah plant. The new mill will have a production capacity of 300t/hr. The project is budgeted at around US$40m and it has an implementation period of 15 months. More binding detailed contracts are expected to be signed by mid-January 2022.

The cement company also plans to appoint a consultant to define the scope of work and identify contractors to build a 30MW solar unit near the Buraydah plant. It said that the company would not incur any capital or operational expenditure as the payment would be based on actual consumption. The solar unit project is part of the country’s Saudi Vision 2030 strategic framework to reduce dependence on oil.

Singapore: Pan-United Concrete has started a partnership with Surbana Jurongto study the feasibility of using electric and hydrogen fuel cells to power a fleet of more than 1000 trucks. The agreement is intended to support Pan-United’s sustainability targets to offer only low-carbon concrete by 2030, carbon-neutral concrete products by 2040 and to become a carbon-neutral ready-mix concrete company by 2050.

Yeo Choon Chong, the Chief Executive Officer of Surbana Jurong's Association of Southeast Asian Nations division, said, "We applaud Pan-United's ambition to decarbonise its heavy vehicle fleet and are excited to contribute to its sustainability initiative by leveraging our expertise in electrification and hydrogen solutions. Partnerships are a key method of accelerating our collective efforts to build for a safe, sustainable and resilient future for all."

China: Hebei province will screen out a total of 1000 existing factories for replacement with less-polluting alternatives under the Chinese government’s 14th Five Year Plan, which covers the period up to the end of 2025. The Xinhua News Agency has reported that factories, including cement plants, will undergo upgrades in order to conform to the plan’s emissions restrictions or close down. The province currently has a total of 233 green factories. Under the 13th Five Year Plan, which concluded in 2020, it reduced its installed cement production capacity by 12Mt/yr.

Norway: Germany-based MAN Energy is supplying a compressor system for a carbon capture and storage (CCS) unit being built at Norcem’s Brevik cement plant. The scope of supply includes an RG 63-7 type electrically-powered compressor train. The steam generators cool the CO₂ mixture between the compressor stages and generate steam that is in turn used for capture. The project will be the first to use the ‘Carbon Capture Heat Recovery’ technology (CCWHR) developed by MAN and Aker Carbon Capture. This new process allows the heat emerging from the compressor system to be recovered and used as steam to meet approximately one third of the total heat demand from the Aker Carbon Capture plant. Consequently, MAN says that the system solution demands less energy compared with conventional carbon-capture technologies.

Alexander Sobolyev, Head of Standardisation & Solutions at MAN Energy Solutions, said: "As part of the Norcem project, the digital-twin-based engineering approach of MAN Energy Solutions has led to concrete optimisations. The dynamic process simulation showed that originally planned system components, including heating, valves and additional pipes for safe plant operation, were not required. The time taken for a cold start of the plant can thus be reduced from around 12 hours to 20 minutes – an important characteristic as quick-start capability is always a central criterion for renewable energies."

Germany: Holcim Germany has published environmental reports for 2020 focused on each of its cement plants. The subsidiary of Switzerland-based Holcim has decided to target its reports on local issues by issuing separate reports for each of its four integrated plants in the country, at Beckum, Höver, Lägerdorf and Dotternhausen respectively. Each report covers national developments for the sector and the company. Local data is then included as well as data on connected cement grinding and concrete plants. The reports can be downloaded from Holcim Germany’s website.
