China: Hoffmann Green Cement Technologies has secured a Chinese patent for its high performance alkaline activation (H-P2A) geopolymer technology. The patent will enable it to begin to market its clinker-free cement in the country.

Co-founders Julien Blanchard and David Hoffmann said "We are very proud to extend the intellectual property of our H-P2A technology to a market with such great potential as China. The achievement of this first milestone marks our commitment to raising the barriers to entry in as many markets as possible around the world."

India: Sustainable roofing specialist Visaka Industries has acquired a 20-year patent for production of ATUM, a roofing system consisting of cement boards with integrated solar panels. The company says that the product, which has been in development since 2016, is both insulative and capable of generating up to 28W/m2 of power.

US: Solidia Technologies has filed a patent for a new hydraulic cement consisting of Ordinary Portland Cement (OPC) and other supplementary cementitious materials (SCM) including lime, alkali hydroxides, clay minerals and over 10% synthetic pozzolan.

Solidia Technologies said, “In order to reduce global CO₂ emissions it is necessary to adopt new approaches to create a new generation of hydraulic cements. The most efficient cement kiln can produce OPC clinker with an associated emission of 816 kg of CO₂/t. Blending the ground cement clinker with SCM, which have low or zero associated production CO2 emissions, reduces the total embodied CO₂ of the final product. Using a cement with the lowest possible clinker factor for a given application is the most common industry approach to reducing the CO₂ footprint of concrete.”
