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...

Egypt: manufacturers encouraged to increase AF use

14 October 2016, Published under Cement News

The 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 change

23 September 2016, Published under Cement News

This 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 ...

Positive signs of recovery

CEMBUREAU released figures this summer on the production performance of its members in the European cement sector in 2015. They reveal a modest positive annual growth rate of 0.9 per cent to 248Mt, when compared to the year before. The growth experienced by Europe's cement indsutry in 2015 reflects positive signs of recovery The annual growth registered by the European cement sector in 2015 reflects positive signs of recovery. Even with significant differences across EU member s...

CSI: trend of continuous decline in CO2 emissions by cement industry

19 September 2016, Published under Cement News

The Cement Sustainability Initiative’s (CSI) recently-published “Getting The Numbers Right” (GNR) report for 2014 has identified a trend of continuous reduction in CO2 emissions by the cement industry over the last decade. “The 2014 results show the European cement industry is maintaining the improvements of recent years and this in line with its low carbon economy roadmap. According to the database, clinker and cementitious production started to grow again by 2.9 per cent YoY whilst net ...
