GGBS slag cuts 408Mt of CO2 from UK's OPC production in 202205 October 2023, Published under Cement NewsIn 2022, around 38.5Mt of ferrous slag were produced in the European Union and the UK. Approximately, 99 per cent of this could be used primarily as a building material and in fertilisers. This means that the by-products of the steel industry have substituted more than 1.1bnt of natural rock in the period from 2000-22. In addition, the use of granulated blastfurnace slag, replacing Portland cement clinker, in cement avoided the emission of 408Mt of CO 2 over the same period. Last year... |
