cement technology

Blue Planet Systems has developed a patented Geomimetic® Mineralization Technology that captures carbon dioxide (CO₂) from any emission source and transforms it into carbon-negative aggregate for the construction industry. This innovative approach uses waste CO₂ and combines it with calcium sourced from industrial byproducts and waste materials to create synthetic limestone aggregate, permanently locking CO₂ within the material. Blue Planet provides a sustainable and circular solution to concrete production by mimicking the Earth's natural limestone formation process.

Brimstone has developed an industrial process for producing industry-standard Portland cement with significantly less carbon emissions. Brimstone’s decarbonized process is a breakthrough in cement production, making industry-standard Portland cement with carbon-free calcium silicate rock instead of limestone. Brimstone cement is chemically and physically identical to conventional Portland cement, with the same quality and performance. Portland cement contains two core products: Portland cement clinker and supplementary cementitious materials (SCM).

Sublime Cement™ is a carbon-neutral alternative to ordinary Portland cement (OPC). Sublime’s novel cement process uses electrochemistry to extract reactive calcium (Sublime Lime™) and Silicates from abundant raw materials that are then blended into a final cement. In the electrochemical process, entire parts of non-carbonate rocks are converted into cement at ambient temperatures. The process uses carbon-free feedstocks and low temperatures, thus, Sublime Cement does not emit CO2. This cement is a drop-in replacement for OPC, meeting or exceeding construction performance standards.
