FLSmidth has announced that it will lead a new consortium to mature and deploy carbonation technologies in the cement industry. According to the company, the consortium will be funded by the EU Commission and feature world-class specialists alongside FLSmidth research and development engineers and experts from leading universities, technology providers and research institutions.  With the aim of further eliminating CO 2  emissions from the production of cement, the consortium, which is na...

Denmark installs cement-free pipes

06 September 2022, Published under Cement News

Danish 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 challenge

03 November 2021, Published under Cement News

With 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. Green construction and decarbonisation is expected to impact the way cement plants manage their energy consumption Worldwide trends such as increasing population numbers and ...

Belterra clay could replace limestone in cement production

11 October 2021, Published under Cement News

In 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...

Clay calcination – accelerating cement’s green transition

30 August 2021, Published under Cement News

With the cement industry’s goal of working towards saving the planet, FLSmidth proposes a simple switch: replace 30 per cent of clinker with calcined clay for up to a 40 per cent reduction in CO 2 emissions. In this article the company outlines why the move is not only smart and efficient but is something almost every cement manufacturer could do right now. By Steven Miller, FLSmidth, Denmark.

Producing boron cement

24 August 2021, Published under Cement News

The creation of low-energy belite clinker is a specific area of research that aims to reduce CO 2 emissions from the cement manufacturing process. Boron minerals, of which Turkey has 73 per cent of the world’s reserves, are a possible raw material that can be used in the production of belite cements. TÜRKÇIMENTO, the Turkish cement manufacturers’ association has carried out a study into the use of colomonite boron ores to determine their suitability for the production of boron cement. By Se...
