US: Prometheus Materials' microalgae-based biocement has demonstrated 12 times greater sound absorption than ordinary Portland cement (OPC). Prometheus Materials produces its biocement at ambient temperature, with no 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.”

US: Prometheus Materials has been awarded ASTM C129 certification for non-loadbearing concrete masonry units (CMU) and ASTM C90 for loadbearing CMUs for its bio-cement product. The company is commercialising a process to produce cement and concrete using microalgae.

Loren Burnett, the chief executive officer of Prometheus Materials, said “We are thrilled to have achieved these two foundational certifications as we proceed in full-force with our goal of decarbonising construction.” He added, “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.”

US: Prometheus Materials has successfully developed cement-free blocks from a material produced by biomineralising cyanobacteria. Dezeen News has reported that the American Society for Testing and Materials (ASTM) has approved the materials for construction applications.

Director Wil V Srubar III said "Coral reefs, shells and even the limestone we use to produce cement today show us that nature has already figured out how to bind minerals together in a strong, clever and efficient way. By working with nature to use existing microalgae to bind minerals and other materials together to create new types of sustainable biocomposite building materials, we can eliminate most, if not all, of the carbon emissions associated with traditional concrete-based building materials."
