It established Science-Based Targets Initiative (SBTi)-verified well below 2°C 2030 climate action goals and joined the UN’s Race to Zero and the Business Ambition for 1.5°C coalition. It also became a founding member of the World Economic Forum’s First Movers Coalition for zero-carbon economic development.

The year also brought major Sustainability and Circular Economy milestones, including managing 57 times the volume of waste it sent to landfill, positively impacting 25m lives through its Social Impact Strategy and processing 61% of global sales through its Cemex Go digital sales platform. For the second consecutive year, its Net Promotor Score was 68, ‘substantially above’ the construction and engineering industry average.

Germany: Master Builders Solutions has announced the addition of a new range of admixtures consisting of MasterEase and Master X-Seed to its admixtures portfolio. The company developed MasterEase and Master X-Seed to best enable European cement companies to produce cement of the EU’s new CEM II/C-M and CEM VI Portland-composite cements. Master Builders Solutions hopes that the new products will drive the construction industry’s transition to low-clinker cements and CO2-optimised concrete.

Parent company MBCC Group’s European president Christian Geierhaas said “Providing sustainable solutions is a key factor of Master Builders Solutions’ portfolio and overall strategy. Strong partnerships are essential and support and accelerate the development of significant innovations. We work with major players to continuously develop efficient admixtures to add value to our customers and achieve a long-term sustainable positive effect on the construction industry.” He added “In addition to the usual performance criteria, such as fluidity and compressive strength, our new solutions for our ready-mix customers are characterised by their outstanding robustness. Our admixtures provide an important differentiator by guaranteeing consistently high quality concrete, even upon variation of the cement type and fluctuation of the raw materials used to produce these new, more sustainable cements.”

Australia: First Graphene has started a five year collaboration research and development agreement with construction chemicals manufacturer Fosroc International to develop its PureGraph graphene-based cement additive product range. First Graphene will provide access to its formulation and dispersion process technologies and Fosroc will take responsibility for additive raw material supplies and formulations, mixing and dispersion and extensive laboratory trials. The objective of the deal is to jointly develop a range of PureGraph-enhanced cement additives that Fosroc will add to its portfolio of specialty products.

Michael Bell, the managing director and chief executive officer of First Graphene, said, “The agreement with Fosroc is a significant further step for First Graphene as we implement our go-to-market plan to become the world’s leading supplier of graphene-enhanced cement and concrete solutions. Fosroc has significant penetration into multiple global markets that will be highly beneficial in helping expand our reach and educating the market on the significant benefits, including emission reductions, that graphene-enhanced products provide.”

First Graphene says that the clinker factor of cement can be reduced by up to 20% through the use of its PureGraph additive products during the final grinding phase of cement production.

Colombia: 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."

Croatia: Holcim Croatia plans to invest Euro1.28m to upgrade the dosing equipment of its Koromačno cement plant’s kiln line. The planned upgrade will enable the line to increase the proportion of alternative materials used in its cement production, thus equipping the plant for low-carbon cement production. Innovation Norway has granted the producer Euro441,000 towards the cost of the project.

Managing director Nikola Kovačević said “Mineral admixtures in cement have a threefold benefit: on the one hand, different characteristics are created in the cement to meet the requirements of different types of construction; on the other hand, the exploitation of natural resources decreases. Thirdly, the carbon footprint of the cement is thus reduced through the lowering of the clinker factor.”

US: LafargeHolcim US says that the integrated 2Mt/yr Midlothian plant in Texas will become the first cement plant in the country to fully convert to Portland Limestone Cement (PLC) production. The unit will switch to producing the company’s OneCem product, a blended cement manufactured with up to 15% of finely ground limestone. The move is intended to help LafargeHolcim US and its customers meet sustainable construction goals and lower carbon emissions.

“This is an important, but not unique, step for us. We were the first to produce OneCem, a PLC product, in one of the fastest-growing metro areas in the country, and fuel our industry’s step towards a zero carbon future,” said Patrick Cleary, senior vice president of sales, LafargeHolcim US Cement.

The company is promoting OneCem as an alternative to Ordinary Portland Cement in terms of concrete workability, set time, durability and strength development. It can be incorporated into a broad spectrum of applications that will support foundational structures. The product is available in the Western and Southern regions of the US and the company plans to ‘rapidly’ expand production.

India: Vedanta Aluminium has expressed interest in a long-term collaborative partnership with a cement producer. The Economic Times newspaper has reported that, in such a partnership, Vedanta would supply the producer with fly ash and bauxite residue with which to produced reduced-CO₂ cement. The company said that a cement producer could be its ‘perfect circular economy partner.’

Chief executive officer Rahul Sharma said "We hope the Indian cement producers come forth to work with us on this innovative solution, which is a true win-win scenario for the industry and environment.”

Switzerland: The Swiss cement association Cemsuisse has published Roadmap 2050, a plan for the achievement of net carbon neutrality by 2050. As part of the plan, the association says that Swiss cement producers will launch carbon capture and storage (CCS) installations at their plants from 2030. Individual companies’ plans also involve the reduction of products’ clinker factors and alteration of cement kiln fuel mixes.

Cemsuisse lobbied the government to approve producers’ mining permits in order to prevent an increase in imports from 686,000t in 2020. The figure corresponds to 15% of the nation’s 4.70Mt consumption.

US: The California Nevada Cement Association (CNCA) has published a plan for the Californian cement industry to meet its target of carbon neutrality by 2045. The plan consists of three pathways, namely: a reduction in process emissions including by alterations to clinker factor and type of additives; an increase in alternative fuel (AF) substitution; and a switch to renewable energy. The association said that the aims are achievable by close stakeholder coordination, constructive public policy engagement and a situational approach based on a flexible portfolio of pathways.

Mexico: Cemex says that the ongoing coronavirus pandemic will not delay its ‘Climate Action Strategy’ that was previously announced in February 2020. The building materials producer has developed a CO₂ reduction roadmap to help guide it towards a towards a targeted 35% reduction in net specific CO₂ emissions between 1990 and 2030.

The roadmap consists of: reduction of CO₂ emissions of clinker through “the production of novel clinkers with lower heat consumption”; use of “alternative decarbonated raw materials”; increased alternative fuel substitution; and increased substitution of clinker with “alternative cementitious materials, using admixtures to enhance strength, and adopting new grinding technologies to improve performance”; in addition to the increased use of renewable energy.

Cemex chief executive officer (CEO) Fernando Gonzalez said, “Climate change is one of the biggest challenges of our time, and we believe that we can continue to address it as a fundamental component of our efforts to recover from the Covid-19 pandemic.”
