LafargeHolcim launches EcoLabel green cement and concrete brand
28 October 2020Switzerland: LafargeHolcim has announced the launch of EcoLabel, a brand to encapsulate its green cements and concretes. All products bearing the label must have either a 30% lower carbon dioxide (CO2) footprint compared to the local industry standard or use 20% recycled content. The company says that the reason behind EcoLabel is to “support builders in making greener choices” and to “accelerate the company’s Net Zero Journey.”
Chief sustainability officer Magali Anderson said, “I am very proud of how our company is turning our net zero pledge into action across more than 70 countries, with our broad range of green building solutions. The EcoLabel is a key milestone on this journey, confirming LafargeHolcim’s commitment to lead the way in sustainability and innovation.”
Mexico: Holcim Mexico says that it supplied a record 70,000m3 of concrete to the Dos Bocas oil refinery in September 2020, bringing the total volume supplied since major infrastructure work began at the site in March 2020 to 300,000m3. El Norte News has reported that the company is supplying the project from three sites with a total capacity of 4000m3/day: the Paraíso, Refinería and Dos Bocas concrete plants. Holcim Mexico noted that, of the 215 employees involved in the project, 50% are women.
Chief executive officer (CEO) Jaime Hill Tinoco said, “Dos Bocas is one of the most important infrastructure works in the history of LafargeHolcim and Holcim Mexico.” Upon completion in late 2022, the company expects to have delivered 2.14Mm3 of concrete to the project.
Canada: Testing specialist Giatec has launched Roxi, an artificially intelligent (AI) concrete visualisation programme for builders. PR Newswire has reported that Roxi “provides insights regarding the amount of cement that is needed, including the amount that can be removed without compromising the concrete's setting time or strength development,” aiding project completion while diminishing extraneous cement demand.
The company thanked Sustainable Development Technology Canada for its US$1.83m grant towards the development of Roxi, part of the fund’s US$44.6m total contribution to “clean technology projects” so far in 2020.
Paris council halts Lafarge France Bercy expansion plans
08 October 2020France: The council of Paris has voted to withdraw permissions for a planned expansion to LafargeHolcim subsidiary Lafarge France’s Bercy concrete plant after protesters captured footage of a slurry spill that the company called ‘exceptional.’
Finanznachrichten News has reported that the council also voted to launch a “mission to reassess cement and building materials production by 2040” to preserve the local environment, as a result of which it expects the city to shift its reliance to imports of cement and concrete from surrounding areas.
MPA launches UK concrete and cement net zero roadmap
07 October 2020UK: UK Concrete and the Mineral Products Association (MPA) have launched a roadmap for the concrete and cement industry to become net negative by 2050. It plans to do this through decarbonised electricity and transport networks, fuel switching, greater use of low-carbon cements and concretes as well as carbon capture, use or storage (CCUS) technology.
“We have already made significant progress to reduce carbon emissions but are under no illusion about the scale of the net zero challenge,” said Nigel Jackson, chief executive of the MPA. “Achieving this will require the wholesale decarbonisation of all aspects of concrete and cement production, supply and use. The concrete and cement industry as one sector alone cannot deliver net zero and we will only be able to go beyond net zero with concerted support from government, as well as with significant changes across the wider construction, energy and transportation sectors.” He added that the roadmap could be delivered without offsetting emissions, offshoring production facilities or ‘carbon leakage.’
The ‘Roadmap to beyond net zero’ calculates the potential of each technology and the carbon savings which can be achieved. CCUS technology is vital to delivering net zero manufacturing and according to the roadmap will deliver 61% of the required carbon savings. It intends to achieve a net negative industry by 2050 by the ability of concrete to absorb carbon dioxide during use and the thermal properties of concrete in buildings and structures to reduce operational emissions.
The MPA is also lobbying the government for a financial support model including for the capital and operational costs of carbon capture by no later than 2021. This is desired to ensure the technology can be developed, deployed and become an investable proposition in the 2030s.
Hoffmann Green Cement Technologies to supply low-CO2 concrete to social housing project
07 October 2020France: Social housing developer Immobilière 3F says that it has signed a contract with construction company Groupe GCC for the use of Hoffmann Green Cement Technologies' 78% reduced-carbon dioxide (CO2) emissions concrete for the construction of an 85-unit housing project in Saint-Leu-la-Forêt, Île-de-France.
Groupe GCC says that it participated in the development of the concrete as part of a three-year development partnership agreement with Hoffmann Green Cement Technologies signed in July 2020.
India: The city corporation of Mysore, Karnataka and non-governmental organisation (NGO) Susthira have announced plans to set up a waste building materials recycling plant. The Projects Today newspaper has reported that the corporation has purchased a 20,000m2 site in the suburb of Kuppalur on which for Susthira to build and operate the plant, which will process waste cement slabs and concrete bricks from construction and demolition sites.
HeidelbergCement supplies concrete for 3D-printed Beckum house
30 September 2020Germany: HeidelbergCement says that it has supplied concrete for the construction of an 80m2 two-storey detached house in Beckum, North Rhine-Westphalia. The concrete contains i.tech 3D, a ground sulphoaluminate clinker developed by HeidelbergCement subsidiary Italcementi for use as an additive in concrete for 3D printing. Engineering & Innovation head Jennifer Scheydt said, “The development of a cement-bound material for 3D printing is a major challenge. It should be easy to pump and extrude. It must also quickly develop sufficient load-bearing capacity so that the lower layers do not give out under the load of the upper layers. At the same time, the bond between the layers must be ensured.”
The property, the first of its kind, will consist of three-shelled insulation-filled walls when completed in late 2020.
Buzzi Unicem announces crisis-proofing strategy
15 September 2020Italy: Buzzi Unicem says that it has implemented a number of measures to enable it to deal with any economic downturn resulting from the financial impacts of the coronavirus outbreak. The Il Sole newspaper has reported that the company’s strategies fall under two headings, namely increasing efficiencies and improving products and services.
