Betolar launches partnership with Tara to encourage uptake of low-carbon concrete in India
10 November 2021India: Finland-based Betolar has launched a partnership with sustainable housing company Tara. The arrangement is intended to enhance India’s ‘green’ construction sector by encouraging the use Betolar’s pre-cast concrete products. These use waste inputs to create a low-carbon alternative to Ordinary Portland Cement. Betolar has been working with Tara since around 2019 to bring its commercial products to the local market.
Betolar's Head of Asia said, "There is a tremendous appetite for sustainable construction materials in India which we are tapped into through our work with Tara and its mission to develop alternative and sustainable models for rural development, democratizing construction from the bottom up."
India: UltraTech Cement has committed to the Global Cement and Concrete Association’s 2050 roadmap for net zero concrete. It says that in realising the commitment, it hope to contribute to building the sustainable world of tomorrow. The Roadmap also includes a sectoral commitment to cut CO2 emissions by a further 25% by 2030.
Argos commits to 29% CO2 emissions reduction by 2030 and carbon neutral concrete by 2050
27 October 2021Colombia: Cementos Argos has announced its new commitment to reduce the CO2 emissionsfrom its cement operations by 29% over a period ending in 2030. The company has additionally committed to producing all of its concrete CO2-neutrally by 2050. It said that its strategy will comprise several carbon mitigation techniques, including maximised alternative fuel (AF) substitution, clinker factor reduction, energy optimisation, clean technology upgrades and a diversification of its range of its cement range to include more sustainable products.
Chief executive officer Juan Calle said "We are determined to face this important challenge and we are convinced that we can build the future we have planned and achieve a more prosperous, inclusive and low-carbon world if we work together with determination to accelerate this transition." He added "We will continue to strive to implement tangible actions, achieve measurable progress each year and deliver information about out opportunities and progress transparently."
Lee Sleight appointed as managing director of Aggregate Industries’ Readymix Concrete division
20 October 2021UK: Aggregate Industries has appointed Lee Sleight as the managing director of its Readymix Concrete division. He has also been appointed to the company’s executive committee.

Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO2. EuropaPress has reported that the use of CO2 would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO2 from the concrete’s production.
Spain: The eruption of the La Cumbre Vieja volcano has destroyed a concrete plant on La Palma in the Canary Islands after engulfing it with lava. EuroNews has reported that the eruption, which begun on 19 September 2021, has displaced 6000 people on the island. The La Cumbre Vieja volcano previously erupted in 1971.
Forty cement and concrete companies commit to the Global Cement and Concrete Association’s Roadmap to Net Zero
12 October 2021World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).
Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO2 emissions by 2030 and the elimination of 4.9Bnt of CO2 emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.
GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”
Australia: Boral plans to run a pilot scale carbon capture and storage unit at its integrated Berrima Cement plant in New South Wales. The project follows an allocation of a US$1.7m grant from the Australian Government’s carbon capture and utilisation and storage (CCUS) Development Fund in June 2021. The pilot intends to develop and test a re-carbonation strategy for CO2 storage. Captured CO2 will be stored in recycled concrete, masonry and steel slag aggregates. In its 2021 sustainability report, the buildings materials company said that, “The relatively low capital and operation costs, abundance of selected waste materials and the financial return potential due to the increased value of processed aggregates are key drivers for adoption of this technology.”
UK: Global building materials supplier Cemex UK has launched its Buildings Made Better range of renovation and refurbishment products and services. The company says that the range offers customers easy access to low carbon, energy efficient or water-conserving building solutions. It includes a wide selection of existing and new products including its Vertua low carbon concrete. The producer said that the solutions support the construction phase and the whole lifecycle of the building.
Cemex Materials West Europe quality and product technology director Steve Crompton said “The renovation of existing buildings can lead to significant energy savings for all, as buildings account for over 40% of energy consumed. More than 220m buildings in Europe, representing approximately 85% of the building stock built before 2021, will mostly still be standing in 2050, yet currently only 1% of buildings undergo energy-efficient renovation each year. The energy performance of buildings is a major area for improvement in public policies, for new build and the renovation of the existing stock. From residential housing, to public buildings and urban schemes, across the board, we’re demonstrating to our customers that by improving the built environment, we can significantly improve our natural environment too.”
He added “Concrete has a critical role to play in the transition to a low-carbon economy. We have the aspiration to deliver net zero CO2 concrete globally by 2050, which will contribute to the development of climate-smart urban projects, sustainable buildings and climate resilient infrastructures. By bringing together a comprehensive range of sustainable products that support the important area of retrofit, we are offering our customers easy access to the right products for the job whilst keeping the environment front of mind.”
