Burning used tyres

24 May 2018, Published under Cement News

One way of reducing the fossil fuel requirement in clinker production is through the use of alternative fuels (AFs). Walter Materials handling, part of the ATS Group, looks at one plant that has invested in the burning of end-of-life tyres to reduce its thermal energy costs, lower its CO 2 emissions and tackle tyre disposal issues.

CDP report claims producers still need to vastly reduce CO2 levels

10 April 2018, Published under Cement News

A new report by the Carbon Disclosure Project (CDP) entitled 'Building Pressure', which analyses 13 of the world's largest publicly-listed cement companies, reveals that they need to more than double their emissions reductions if they are to limit global warming to below 2˚C, as agreed in the Paris Climate Deal. The companies analysed in the report have a total market capitalisation of US$150bn and represent 16 per cent of global cement production. The CDP has assessed companies across fo...

MPA report highlights CO2 emissions fall for UK cement producers

02 February 2018, Published under Cement News

The Mineral Products Association (MPA) reports that carbon dioxide emissions per tonne of cement fell by two per cent between 2016-17 in the UK. However, for aggregates and asphalt production CO 2 emissions incresed in the country, while readymix concrete production saw a decline in emissions. The data collected forms part of the MPA's Sustainable Development Summary data which was recently launched. Commenting on the information, MPA Chief Executive, Nigel Jackson, said: "The MPA support...

Not simply calcining

10 January 2018, Published under Cement News

While the primary purpose of the calciner in a cement plant is to aid decomposition of calcite from the preheated raw meal, the need to lower CO 2 emissions and the introduction of alternative fuels has broadened the range of requirements that modern-day calciners need to address. By Dr Heiko Schürmann and Norbert Streit, KHD-Humboldt Wedag GmbH, Germany. Figure 1: the main purpose of the calciner is to decompose calcite from the preheated raw meal, which is the most energy-intens...

HeidelbergCement working to lower carbon emissions

21 November 2017, Published under Cement News

HeidelbergCement and the European Molecular Biology Laboratory (EMBL) have signed an agreement on a three-year collaboration to exchange scientific and technical knowledge, according to a company press release. HeidelbergCement has pledged to lower specific CO 2 emissions by 30 per cent by 2030 in comparison to 1990 levels.
