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. This agreement is an attempt to further that goal by exploring solutions in CO 2 reduction alongside EMBL. This will be achieved through a series of conferences a...

Spain's cement industry in drive to reduce CO2 emissions 80% by 2050

18 October 2017, Published under Cement News

According to a new report by Oficemen, the Spanish cement industry is undertaking steps to reduce its CO2 emissions by 80 per cent by 2050 when compared with 1990 as base year. In its “Roadmap of the Spanish cement industry for the reduction of carbon emissions by 2050”. Conventional means such as increased energy efficiency and co-processing will enable the sector to reduce its CO2 footprint by 35 per cent compared to the base year. The roadmap foresees improvements in thermal efficiency ...

German cement industry invests considerably in environmental protection

11 October 2017, Published under Cement News

German cement producers further invested in plant optimisation in 2016, keepign them in a leading role worldwide in terms of environmental compatibility, according to the German cement association, VDZ. The sector has taken action to reduce NOx emissions through plant optimisaiton as well as extensive research to test innovative exhaust gas cleaning technology under the particular conditions applicable during cement production. As a result, SCR technology has been brought to industrial ma...

11 July 2017, Published under Cement News

HeidelbergCement has published its Group Sustainability Report 2016 which shows specific net CO 2 emissions have been reduced by 22.6 per cent compared to the base year of 1990. This eighth Sustainability Report for the group was prepared in accordance with the guidelines of the Global Reporting Initiative (GRI G4) and summarises important topics and challenges for HeidelbergCement in its drive for sustainable development. The report focuses on targets, measures and achievements of the co...

A case for low-lime cement

22 February 2017, Published under Cement News

The cement and concrete industry is re-inventing itself through new and efficient processes to not only reverse its environmental impact, but to make improvements to the whole supply chain of the building materials industry. This sustainability drive has seen the emergence of low-clinker cements, including cements that have a reduced lime content. By Dr Vahit Atakan, Dr Sada Sahu and Dr Nick DeCristofaro, Solidia Technologies, USA. Pavers ready for curing: Solidia Concrete ® cures wi...

Kiln emissions – more than just hot air

01 February 2017, Published under Cement News

In last month’s Technical Forum we promised to return to the topic of cement kiln emissions, which were said to be both simple and complex, benign and noxious. The challenge is to see the broad simplicity, which then allows the increasing complexity to be understood. By Dr Michael Clark, UK. Kiln emissions include a wide range of gases – some benign but others noxious At the macro level cement kiln emissions are indeed simple. The raw materials used for manufacturing clinker are...

New Zealand: eco-friendly cement developed

24 January 2017, Published under Cement News

New Zealand cement company, HR Cement, is to launch a ground-breaking low-carbon footprint cement that helps reduce global CO 2 emissions. HR Cement, based in Mt Maunganui, developed the more environmentally-friendly ECO-CEM cement with the potential to reduce the carbon footprint of concrete utilised on construction sites by 15-30 per cent, according to Chris Hall, managing director of HR Cement. The company’s location within a volcanic field near high-quality and natural Pozzolanic ...

CSI and cement leaders welcome The Paris Agreement's activation

04 November 2016, Published under Cement News

The Paris Agreement entered into force on 4 November. Members of the Cement Sustainability Initiative (CSI) welcomed the news as a key milestone in establishing a stable regulatory framework to enable the business community to scale up the implementation of low-carbon solutions for climate change mitigation and adaptation. On 5 October 2015, 55 Parties to the Convention (UNFCCC), accounting in total for at least an estimated 55 per cent of the total global greenhouse gas emissions, deposit...

Biomass matters

24 October 2016, Published under Cement News

When accounting for CO 2 emissions from the manufacture of cement clinker it is important to know the biomass content of the fuels used to fire the cement kiln, as that biomass content is deemed to be ‘carbon neutral’ and therefore does not count in the CO 2 emission. The biomass content of alternative fuels is key in determining the carbon neutrality of the fuel As this month’s Technical Forum is being written, China and the USA have announced their ratification of the Paris ...

Belgium: LEILAC project reaches FEED phase

19 October 2016, Published under Cement News

The Low Emissions Intensity Lime & Cement (LEILAC) consortium has completed the Preliminary Front End Engineering Design (pre-FEED) study for the carbon capture pilot plant. The project will now enter the full Front End Engineering Design (FEED) phase following a decision taken at the General Assembly meeting hosted by ECN on 29 September in Petten, The Netherlands, where results from the preliminary project phase were reviewed. The five-year LEILAC project, supported by the European Uni...
