World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO₂ cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO₂ emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:

GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”

UK: Breedon Cement commenced a 24-hour trial of graphene-enhanced cement production at its Hope Cement plant in Derbyshire on 28 June 2023. The trial advances the work of a consortium led by Australia-based First Graphene. It is using existing grinding aid dosage lines, with minimal adjustment required. Breedon Cement and its partners aim to produce 2000t of graphene-enhanced cement, using 1.2t of PureGRAPH 50. Graphene-Info News has reported that Breedon Cement will supply concrete produced under the trial to Morgan Sindall Construction for use in its building projects. The University of Manchester is also participating in the consortium.

Breedon Cement managing director Jude Lagan said “The role graphene can play in helping to decarbonise the cement industry could be significant, and we are keen to contribute to this process by facilitating what is set to be one of the largest global trials of this kind.”

India: Shree Cement has entered trial cement production at its new 3Mt/yr Purulia grinding plant in West Bengal. The site is the company’s first manufacturing plant in the state, according to the Times of India newspaper. Reuters has reported that the Purulia plant will raise Shree Cement's total installed capacity by 6.4% to 49.9Mt/yr. The producer invested US$67m in the facility, and raised the funds for it through internal accruals.

Managing director Neeraj Akhoury said "The plant has also allowed us to bring more jobs to Bengal, as well as showcase our advanced production systems which meet stringent environment norms." Akhoury indicated that the producer aims to raise its installed capacity by 60% to 80Mt/yr by the end of the 2028 financial year.

UK: Material Evolution raised US$19m in a Series A funding round to scale production of its 85% reduced-CO₂ cement. Material Evolution produces cement at ambient temperature using its own ambient fusion process. Its inputs consist of industrial wastes and feedstocks. Tech Crunch News has reported that venture capital firm Kompas VC led the funding, with participation from fellow venture capital firms Norrsken VC and Circle Rock Capital, as well as quarried materials producer SigmaRoc.

Material Evolution's CEO Elizabeth Gilligan said “Fusion technology has been hailed as the way to meet humanity’s energy needs for millions of years, whilst emitting no CO₂ or other greenhouse gases."
