École Polytechnique Fédérale de Lausanne recognised as Energy Transition Changemaker for LC3 limestone calcined clay cement project
19 December 2023Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO2 emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO2 reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO2 emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.
Australia: First Graphene has partnered with Suvo Strategic Minerals to develop graphene-enhanced metakaolin for use in cement and concrete production. Metakaolin is a pozzolanic material derived from kaolinite clay. The partners believe that the technology has commercial potential to improve concrete performance and reduce CO2 emissions.
Australia/UK: InterGroup Mining has secured just under Euro60m from Luxembourg-based investment group GEM Global Yield as part of a share subscription facility. The Australia-based mining company says it will use the funds primarily for the ongoing development and commercialisation of its Brilliant Brumby kaolin and gold project in Queensland. The company hopes to sell the kaolin for use in cement and concrete production or as a feedstock for high purity alumina (HPA). It says it will be able to drawdown the funds over a 36-month term following a public listing of its common stock.
Neil Miller, the chairman of InterGroup said, “The GEM facility provides a major accelerator for InterGroup as we continue to prove up the scale of our Brilliant Brumby project and the optimal development path for the co-mining opportunity of kaolin and gold. It likewise enables us to continue our important research and development work into the new carbon reduction markets of potential scale that our minerals serve and which complement their existing known end markets.” InterGroup is currently working towards a potential stock market flotation in the second half of 2021.
