UK: The Transition Pathway Initiative (TPI) has conducted a study into the emissions reduction practices of 33 large cement producers. The study concluded that five of the companies are currently aligned with the emissions reduction pathway which would keep the global temperature rise below 2°C by 2050 compared to pre-industrial levels. This corresponds to 15% of large cement companies assessed in the study compared to 14% of large companies in heavy industries globally. The TPI commended the five producers, noting that in global industry “fewer companies are aligned with 2°C after 2030 [than by 2030], because the pace of decarbonisation required in the industrial sector really picks up next decade, requiring drastic falls in emissions between 2030 and 2050 to meet Paris Agreement goals. More industrial companies need to set longer term targets to 2050 that require greater levels of decarbonisation.” Just one aluminium producer and no paper producers are in line with the 2050 target.

TPI Co-Chair Adam Matthews said, “As we enter the transition decade these hard-to-abate sectors are critical to achieving net zero goals by 2050. Whilst it is concerning that so few industrial companies are ready, it is clear new industrial processes based on circular economy principles give us a tipping point of technically viable, economically attractive solutions.”

UK: Cemex UK has announced the launch of Viabase, an engineered asphalt concrete. The company says that the product is especially suited to use in residential housing estate roads, where it will be exposed to construction traffic before being surfaced after houses are built. The launch supports the UK government’s drive to increase house building to 300,000units/yr.

Europe regional asphalt, paving and building products director Carl Platt said, “With Viabase, we are pleased to offer a way to ensure the longevity of housing development roads, which standard materials struggle to provide if the surface course is not placed soon after. Viabase provides a highly durable, low maintenance surface which will meet the challenges presented by heavy duty vehicles and prevent long-term problems in the overall pavement construction.”

The company will produce Viabase at all its UK asphalt plants, where it will be available for delivery to customers or collection.

Mexico: Cemex recorded consolidated cement volumes of 63.8Mt in 2020, up by 2% year-on-year from 62.7Mt in 2019. Ready mixed concrete sales volumes fell by 6% to 47.0Mm3 from 50.1Mm3. Its net sales fell by 1% to US$13.0bn from US$13.1bn although the group has reported a slight rise on a like-for-like basis. Operating earnings before interest, taxation, depreciation and amortisation (EBITDA) rose to US$2.46bn, up by 3% from US$2.38bn. However, sales and earnings picked up significantly in the fourth quarter of 2020.

Fernando A González, the chief executive officer (CEO) of Cemex said, “2020 was one of the most challenging years we have faced but it also was a remarkable year that tested the strengths of Cemex and several of our recent strategic initiatives. I am proud of our performance, the organisation, and how we responded to the sudden arrival of Covid-19 in 2020.”

Cement volumes rose by 6% in Mexico and by 8% in the US, but fell by 1% in Europe, Middle East, Asia and Africa and by 8% in South and Central America and the Caribbean. Prices fell in all regions except Europe, where they rose by 3%, and the US, where they remained level. Annual like-for-like sales and gross profit increases were noted in Mexico, the US and Middle East and Africa.

The group concluded the sales of its 75% stake of US-based Kosmos Cement for US$499m in March 2020 and of ready-mix assets in the UK for US$230m in August 2020.

UK: SigmaRoc has launched Greenbloc, a cement-free concrete block. The product reduces emissions by 77% compared to concrete blocks produced with Ordinary Portland Cement (OPC), corresponding to a reduction of 1.1kg/block.

Chief executive officer Max Vermorken said, "Our Greenbloc range and brand is the brainchild of our innovation and technical teams. It addresses a key challenge in the building products industry - the embodied CO₂ in one of the most widely used building materials: the concrete block.

UK: HeidelbergCement subsidiary Hanson has installed a solar and wind-powered hydrogen generation demonstration unit at its Port Talbot Regen ground granulated blast furnace slag (GGBFS) plant in Port Talbot in Neath Port Talbot. The company says that the project is part of a collaboration with Swansea University’s Energy Safety Research Institute under the European Research and Development Fund’s Reducing Industrial Carbon Emissions initiative. The hydrogen generated by the installation will replace natural gas in the GGBFS plant’s burners.

Head of sustainability Marian Garfield said, “It is estimated that cement is the source of just under 2% of UK CO₂ emissions. With demand for cement and cement replacement products predicted to increase by 25% by 2030, researchers and industry are working hard to reduce the level of CO₂ emissions associated with production. As a leading manufacturer, we take our responsibility very seriously. In the UK we have already achieved a 30% reduction in CO₂ emissions since 1990 across the business and have set an ambitious new target of a 50% reduction by 2030 from the same baseline. We are constantly looking to improve energy efficiency and carbon reduction at our cement and Regen GGBFS plants, so we are delighted to be involved with this innovative research project.”

US: The US Department of Energy has awarded a grant to Cemex USA, UK-based carbon capture and storage (CCS) specialist Carbon Clean and Oak Ridge National Laboratory. The grant covers the implementation of a CCS system at Cemex USA’s Victorville cement plant in California, in addition to the development of a commercially viable carbon utilisation solution. The producer says that the study is due to last 30 months.

President Jaime Muguiro said, “Cemex is committed to being part of the solution to reduce carbon emissions globally and to deliver net-zero CO₂ concrete to all of our customers by 2050. We cannot achieve these aims without innovative technology and collaborative relationships with both public and private organizations who share a commitment to climate action. This grant gives us an excellent opportunity to further develop a new technology to help us all reach our goals.”

UK: HeidelbergCement subsidiary Hanson has announced a planned 80ha expansion of its Ouse Fen nature reserve partnership project with the Royal Society for the Protection of Birds (RSPB) in Cambridgeshire. The company says the additional restored land from its Needingworth quarry will increase the area of the reserve to 298ha.
