US: Prometheus Materials’ microalgae-based biocement has secured certification for use in concrete masonry unit (CMU) mixes. The cement now holds an ASTM C129 certificate for use in non-loadbearing CMUs and an ASTM C90 certificate for use in loadbearing CMUs. Prometheus Materials’ biocement produces concrete with comparable or superior mechanical, physical and thermal properties to ordinary Portland cement (OPC)-based concrete. It offers little-to-no CO₂ emissions and 95% of water used in production is recycled.

Prometheus Materials CEO Loren Burnett said “We are thrilled to have achieved these two foundational certifications as we proceed in full force with our goal of decarbonising construction. Prometheus Materials’ product is poised to change the future of construction, converting one of the most carbon-polluting industries to a low-carbon – and one day net-zero carbon – reality.”

Germany: Dyckerhoff’s Dillingen ready-mixed concrete plant is the company’s first unit to be awarded the R module of the Concrete Sustainability Council (CSC). The unit has been using recycled aggregates in the standardised proportions and types since August 2021 and now customers and clients can have the certified sustainable concrete counted as part of building certifications. The recycled aggregate used in the Dillingen plant comes from a recycling company in the immediate vicinity, so there are no transport costs, which, in addition to the aspect of resource conservation, also contributes to the avoidance of transport-related CO₂ emissions.

Poland: The Building Research Institute has issued environmental product declarations (EPDs) for Cemex Poland’s Vertua Classic and Vertua Plus concrete products.

Materials director Michał Grys said “For us, product certification is another important step towards sustainable construction and a sustainable future. EPD declarations provide our clients with additional confirmation of the properties of products offered by Cemex Poland. They also improve their chances of obtaining LEED or BREEAM certificates for their investments.”
