New report predicts rising pressure on producers to cut emissions19 July 2018, Published under Cement NewsA new report by Moody’s Investors Service suggests that the cement industry could face demand growth of 12-23 per cent by 2050, resulting in a challenge to meet this demand and still make large-scale carbon emissions cuts. "Regulation of the industry is likely to increase and a rise in carbon prices under the EU-ETS combined with a reduction in allowances to the cement sector would have a significant impact on the cash flow of EU cement producers, in the event cement makers were unable to p... |
Bringing on the substitutes18 July 2018, Published under Cement NewsAs part of its drive to reduce its CO 2 emissions, Votorantim Cimentos is using a range of clinker substitutes to lower its clinker-to-cement ratio. As a result, around 86 per cent of its product portfolio in Brazil has a reduced carbon footprint, lowering its impact on the environment. By Silvia R S S Vieira, Votorantim Cimentos, Brazil. The use of substitute materials such as acidic slags (pictured: maganese slag) and calcined clay is key to reducing a cement plant’s carbon foot... |
