The launch of low carbon technology roadmap has opened new avenues for the Indian cement manufacturers in their quest for improving energy efficiency and bringing down the carbon footprint. In an exclusive interview with Philippe Fonta (Managing Director of the WBCSD) throws light on the key features, and the various stakeholders need to focus for the road map to be successful in India.Read article online on Indian Cement Review

India’s cement industry is the second-largest in the world after China’s, and it more than doubled output from 2000 to 2010. The sector is the third-largest energy consumer in India’s manufacturing sector, and because production involves burning limestone, or calcium carbonate, a significant geological repository for carbon, it is responsible for 7% of India’s emissions of carbon dioxide that increase global temperature.
India’s cement industry has already reduced direct and indirect CO2 emissions per tonne of cement by more than a third since 1996, but total emissions are growing with increased production. The new roadmap specifies technologies, policy frameworks and investment plans that would limit that growth to just a doubling or at most a 240% increase. Techniques range from alternative fuels to waste heat recovery and include carbon capture and storage (CCS), with total additional investments through 2050 of USD 29 billion to 50 billion.
The recommendations in Technology Roadmap: Low-Carbon Technology for the Indian Cement Industry also would save the sector at least 375 petajoules of energy in 2050, the equivalent of current annual energy use in Sri Lanka or Bulgaria. Supported by the International Finance Corporation (IFC), the initiative also includes tools and financing for feasibility studies of the roadmap’s low-carbon technology at select plants.

A new PCR for concrete has been issued. The PCR is an update of a previuos PCR and is now aligned towards EN 15804. The PCR has been developed by the World Business Council for Sustainable Development's (WBSCD) Cement Sustainability Initiative (CSI).

ALITinform, November 2012
Cement production consumes large amounts of both raw materials and fuel and produces substantial CO2 emissions. The use of alternative fuels and raw materials in cement manufacturing can reduce the amount of fossil fuels and virgin raw materials needed, and thus reduce the overall environmental impact of the operations. These alternative materials may be either by-products from other industrial processes, or societal waste streams such as municipal solid waste, sewage sludge, discarded tires and plastics.
Co-processing these alternative fuels in the cement industry is a growing opportunity for the cement sector and a possible solution to one of the major challenges for modern society: increasing amounts of waste generated by consumption and production and driven by rapid population growth. Cement kilns provide an effective and appropriate means for treating many waste materials. In turn the materials serve as a replacement for traditional fossil fuels and generate the temperatures required to make cement. Interest in co-processing municipal solid waste and sewage sludge in particular is rising globally as urbanization continues to concentrate human activities in compact areas.Download the full article

With extremely high temperatures required to heat the limestone, cement is a product with a heavy carbon footprint. However, as companies start to use more industrial waste and renewable energy in cement production, some believe the sector could become a leader in “industrial symbiosis” (where one company’s refuse becomes another’s raw material), accelerating progress towards a zero-waste world.
Philippe Fonta, director of the WBCSD’s Cement Sustainability Initiative, cites the example of discarded tyres, which in some places are left in dumps where they collect water and become breeding grounds for malaria-carrying mosquitoes. “If these used tyres are no longer abandoned but eliminated by a cement plant, you also have societal benefits,” he says.
The technology behind this kind of matchmaking, or co-processing, is relatively well established. The bigger challenge, however, lies in creating the kinds of infrastructure and industry collaborations that facilitate the trading of waste between waste producers and cement producers.
China News Service, 19 September 2012Taking the opportunity of the CSI Forum in China, Philippe Fonta, CSI Director sat down with the new CEO of Holcim, Bernard Fontana and spoke to the Chinese press about co-processing of cement industry worldwide and particularly, in emerging markets like China. Discussions focused on the economic and social benefits the cement industry can bring upon with engagement on co-processing activities and thus contribute to a more sustainable future for all.

Guangzhou Daily, 4 September 2012Co-processing alternative fuels in the cement industry provides an ideal means of disposing of wastes, while generating the energy required to make cement. It could be a win-win solution for our society to manage municipal wastes and sludge efficiently. The 2012 CSI Forum brought together experts in the area from all over the world to explore how to apply a pragmatic solution to the Chinese market.

Ccement.com, 2 September 2012With theme on "Co-processing and Green Development", the 2012 CSI Forum opened curtains at Guangzhou today. More than a hundred delegates from cement industry all over the world will join this important annual event of the CSI. Following the forum meeting and plant visit in Guangzhou, the discussion will move to Beijing for a policy workshop engaging representatives from relevant Chinese governments.

World Cement, September 2012
Carbon emissions has always been an important focal point for the cement indsutry in its role to play in sustainable development. In order to report on the industry's emission levels, the WBCSD's CSI has developed a benchmarking tool that provides the relevant information to allow the industry to monitor and compare its performance across regions, year-on-year. The Getting the Numbers Right (GNR) database provides aggregate anonymous data gathered from a large sample of cement producers, across various countries and regions.
Now in its 6th year of publication, the GNR database is a voluntary, independently managed global information database providing accurate, verified data on the cement industry's CO2 emissions and energy performance. Using a common protocol for measuring, reporting and analysing the data, it is the most comprehensive public database in operation for any industry worldwide. The data is published as a set of web-based reports for all global regions and selected countries, which can be viewed for free by interested parties.

To help foster sustainability in their industry and the world business community, some of the world’s cement companies came together in 1999 to voluntarily propose best practices, key performance indicators and reporting mechanisms for sustainability, creating the Cement Sustainability Initiative (CSI).
Taking many of these factors into account, Grupos Cementos de Chihuahua (GCC), a new member of the World Business Council for Sustainable Development’s (WBCSD) CSI, has built a cement terminal that is productive, efficient, clean and that takes into account the community at large.
The natural, sustainable benefits of building structures, such as domes, using concrete has been realised by GCC and identified by the WBCSD:
