Orgain Ready Mix Concrete issued notice over Red River spill
26 September 2024US: Authorities have issued a notice of violation to Orgain Ready Mix Concrete for an alleged spillage of concrete into the Red River near its Clarksville, Tennessee, ready-mix concrete plant. Local press has reported that the Tennessee Department of Environment and Conservation received reports of materials dumped at a location along the road from the site. A subsequent investigation found ‘cementitious staining’ and ‘solids-laden discharges’ on the riverbank.
Dublin City Council enacts Low-Carbon Concrete Code
13 September 2024US: The city council of Dublin, California, has enacted the Low-Carbon Concrete Code, requiring a given reduction in CO2 emissions of all ready-mix concrete used in public and private construction projects. Independent News has reported that suitable alternatives to conventional concrete are locally available and offer cost parity, according to the city council.
Néolithe supplies Anthropocite circular aggregates for Marseille bus depot project with Hoffmann Green Cement Technologies
11 September 2024France: Circular aggregates producer Néolithe has partnered with Hoffmann Green Cement Technologies and Groupe GCC to produce a fuel loading slab for a temporary bus depot in Marseille. The slab will be made of Hoffmann Green Cement Technologies’ H-UKR clinker-free cement and Néolithe’s mixed circular materials-based Anthropocite aggregates. The resulting slab will serve as a test for the use of H-UKR concrete in future Groupe GCC projects.
The partners say that a mix of H-UKR cement with 20% Anthropocite reduces CO₂ emissions by 63% compared to CEM II/A cement-based concrete produced using conventional aggregates, to 62kg CO₂eq/m³.
Groupe GCC executive vice-president Patrick Dubourg said "This project perfectly illustrates one of GCC's key priorities: implementing sustainable solutions. The work we've been doing for several years with Hoffmann Green Cement Technologies enables us to take tangible action in this direction, and the partnership with Néolithe enables us to take a further step in the direction of decarbonisation, an essential issue for construction.”
Laurence Hemerit, infrastructure director at customer Marseille Metropolitan Transport Authority (RTM), said "RTM found GCC's proposal very interesting in that it enabled us to carry out a large-scale, long-term comparative test to assess the qualities of low-carbon concrete. Our temporary bus storage site was therefore the ideal candidate for this experiment."
Syracuse tests recycled glass in concrete for infrastructure
09 September 2024US: The City of Syracuse, New York, is pilot-testing a new method of infrastructure construction by incorporating recycled glass as a cement substitute in concrete, reports CNY Central newspaper. A patented process by recycling company KLAW Industries crushes glass into fine powder, reportedly replacing 20% of the cement in concrete from recent projects, including upgrades to pavements. The approach follows successful implementations in the City of Binghamton and by the New York State Department of Transportation, with support from SUNY College of Environmental Science and Forestry and Clarkson University.
Department of Public Works Commissioner Jeremy Robinson said "We’re always looking for the most effective and sustainable approaches to constructing and maintaining city infrastructure. Based on the results of this testing, we can determine if the solution can be expanded to more sidewalks and, possibly, other applications.”
ACT government to use low carbon concrete in future projects
06 September 2024Australia: The Australian Capital Territory (ACT) government has pledged to use low carbon concrete in all future government construction projects, where appropriate, reports Mirage News. This commitment is part of the 'Low carbon concrete policy', designed to cut emissions without significantly raising project costs. The implementation of this policy will begin on 1 January 2025 and will require that designers, engineers and builders provide options for using low carbon concrete options in government projects. This initiative is part of the broader 10-year ACT Sustainable Building Pathway, which aims to embed sustainable practices throughout the building lifecycle.
Minister for Water, Energy and Emissions Reduction, Shane Rattenbury said "Using low carbon concrete is a simple and effective way we can reduce these emissions while supporting local industry. Already in Canberra, we have started using low carbon concrete in significant projects like the new Canberra Hospital expansion and in preparation for Light Rail Stage 2A. This is a fantastic example of how seamlessly low carbon concrete can be integrated into our everyday building projects.”
Clark Brothers Contracting secures conditional approval for Wellington North ready-mix concrete plant plans
15 August 2024Canada: Clark Brothers Contracting has received conditional approval from the council of Wellington North Township to build a ready-mix concrete plant in the town in Ontario.

Vulcan Materials Quarry secures environmental approval for Comal County aggregates quarry
22 July 2024US: Vulcan Materials has secured approval from the Texas Commission on Environmental Quality for its upcoming aggregates quarry in Comal County. The approval is based on the company’s water quality protection plan for the 607 hectare site situated in the Edwards Aquifer recharge zone, which supplies water to 2 million people. The plan involves the use of vegetation strips, berms and flood plain areas, while excavating a total 387 hectare (64%) of the site in nine successive stages.
Vulcan Materials said that it plans to operate the site in a ‘safe, socially and environmentally responsible’ manner, and will ‘protect and conserve’ water.
Heidelberg Materials North America to develop web-based environmental product declaration tool for concrete
19 July 2024US: Heidelberg Materials North America has won up to US$5m from the Environmental Protection Agency (EPA) for the development of a web-based tool to generate environmental product declarations (EPDs) for ready-mix concrete and other building materials. The finances are part of a total US$160m in EPA funding for the decarbonisation of building materials.
Heidelberg Materials North America president and CEO of Chris Ward said "With this funding, Heidelberg Materials can accelerate the push for more sustainable construction materials and transparency across the industry, while also helping our customers make more informed decisions when choosing products with a lower carbon footprint."
Mexican government inaugurates San Lorenzo-Tláhuac demolition materials recycling plant
07 June 2024Mexico: The government commissioned the 500t/day San Lorenzo-Tláhuac demolition materials recycling plant in Mexico City on 6 June 2024. The US$2.18m plant will produce 600m3/day of concrete, as well as concrete blocks at a rate of 2000/day. It will receive demolition materials from the Xochimilco Lagoon, where 14Mm3 was deposited following the 1985 Mexican City earthquake, as well as from current job sites in Mexico City.
Secretary of Works Jesús Esteva Medina noted that the San Lorenzo-Tláhuac plant is the first in public ownership, operating alongside privately-owned plants at Bordo Poniente and Miguel Hidalgo.
