Unlocking the power of waste heat25 September 2023, Published under Cement NewsWaste heat is the largest unused energy resource in the world. Harnessing this untapped potential can be a game-changer. A flexible and proven technology, modular organic-Rankine cycle (ORC) waste heat recovery turns waste heat into electricity while improving business performance, reducing CO 2 emissions, and enhancing overall sustainability in energy-intensive cement production immediately. Through new technologies, ORC modules can now also be used for medium-sized and smaller plants. By ... |
Geopolymer cements to address the GHG challenge11 September 2023, Published under Cement NewsMineral carbonation is being explored within the cement and concrete industry to chemically convert CO 2 emissions into stable minerals leading to permanent CO 2 storage within cementitious materials. Teesside University, UK, is collaborating with nine other industrial partners to decarbonise the cement industry through innovative technology that supports the industrial-scale production of carbon-neutral geopolymer cement through the use of historical industrial by-products and wastes. By ... |
