US: Prometheus Materials' microalgae biocement-based bioconcrete has demonstrated 12 times greater sound absorption than concrete produced using ordinary Portland cement (OPC). Prometheus Materials' bioconcrete contains its biocement, which is produced at ambient temperature, without process CO₂ emissions.

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.”

World: Cemex has announced the launch of new bio-based admixtures which offer CO₂ emissions reductions of up to 70% compared to oil-based admixtures in its Asian, European and Middle Eastern markets. The range includes 10% reduced-CO₂ IsoPlast Bio, 20 - 30% reduced-CO₂ IsoFlex Bio plasticisers and superplasticisers and 50% reduced-CO₂ IsoFlow Bio high-performance superplasticiser technology, as well as CO₂-reducing IsoMill Bio grinding aids. The products will subsequently become available in other markets during 2023.

CEO Fernando González said “Innovation is at the core of our efforts to become a carbon neutral company and foster a more circular building materials industry." He added "Innovative admixtures aim to enhance concrete's sustainable attributes for our customers further.”
