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... |

Denmark installs cement-free pipes06 September 2022, Published under Cement NewsDanish utility company, Aarhus Vand A/S, has become the first customer to install IBF’s Geoprime ® , cement-free pipes. IBF, Denmark’s leading concrete manufacturer, has reduced the CO 2 emissions of its concrete pipes by replacing cement in their manufacture with Betolar’s Geoprime binder. The binder, which is based on blastfurnace slag, more than halves the CO 2 footprint of the pipes compared to ordinary concrete pipes, without compromising on strength, dimensions or resistance to w... |
The cement industry’s energy challenge03 November 2021, Published under Cement NewsWith global cement demand expected to rise by as much as a quarter by 2050, the industry faces a range of challenges to produce in a more sustainable way. One aspect is to reduce its energy input to reflect tighter emissions legislation. By Fabio Mielli and Juliano de Goes Arantes, Rockwell Automation, USA.

Belterra clay could replace limestone in cement production11 October 2021, Published under Cement NewsIn a study, funded partly by the Brazilian Ministry of Education, Martin Luther University Halle-Wittenberg (MLU), Germany, and Brazil’s University of Pará, have found that CO2 emissions can be reduced during cement production by up to two-thirds by adding Belterra clay, unused overburden from bauxite mining. "This layer of clay can be up to 30 metres thick and covers the bauxite deposits in the tropical regions of the earth, for example in the Amazon basin," explains Professor Herbert Pöl... |
