Innovative green process to turn alkali solid wastes into carbon-negative feedstock for the cement industry
Over 2 billion tonnes of diverse alkali solid wastes are generated from Foundation Industries worldwide annually and are primarily disposed of through landfills and stockpiling. The volume of these is expected to double in the next few decades, which has brought significant challenges to the cement and metal industries for reaching Net-Zero targets.
This project will develop an innovative green chemical process to turn these alkali solid wastes into carbon-negative materials which can be used as an alternative feedstock for the production of sustainable cement. The research will focus on optimisation of the process conditions, as well as investigation of the effects of different physical and chemical properties of these novel carbon-negative materials for producing high-strength carbon-neutral cement. The total carbon reduction capacity and sustainability impact of the developed novel process and products will also be assessed and evaluated. This exciting project will be conducted in collaboration with Aggregate Industries/London Concrete and The Materials Processing Institute to seek for sustainable routes to valorise their current solid waste stockpiles.
