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 cement22 February 2017, Published under Cement NewsThe 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 air01 February 2017, Published under Cement NewsIn 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 developed24 January 2017, Published under Cement NewsNew 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 activation04 November 2016, Published under Cement NewsThe 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 matters24 October 2016, Published under Cement NewsWhen 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 phase19 October 2016, Published under Cement NewsThe 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... |
Egypt: manufacturers encouraged to increase AF use14 October 2016, Published under Cement NewsThe Minister of Industry and Foreign Trade, Tarek Qabil, announced that the industry has completed a study on the use on alternative fuel sources to fossil fuels in Egyptian cement plants. Mr Qabil said that the ministry plans to boost cement factories’ reliance on alternative fuel sources such as coal by 6.4-30 per cent within the next 5-10 years. He went on to say that the total coal needs of the country’s cement plants are expected to reach 9.7Mta by 2025. Increasing the use of alterna... |
Responding to climate change23 September 2016, Published under Cement NewsThis week ICR looks at further tightening of pollution control around the world following Cembureau's reminder that the EU Parliament is expected to vote on the provisional directive to reduce emissions of air pollutants this autumn. While Europe is aiming to restrict several hazardous pollutants such as SO2 and NOx through the new National Emissions Ceiling Directive, there are clear indications that China is moving in a similar direction. China ratified the COP21 Paris Climate Change ... |
