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:

Cement producers have renewed efforts to ensure CO2-limiting goals set for their industry use data and methods they have been gathering for years as a stepping-stone to a global carbon market. Countries and regions can use work done by the CSI to gather CO2 figures from cement plants worldwide to speed the setting of targets to limit emissions, according to Philippe Fonta, programme director of the CSI, part of the WBCSD, an association of over 200 companies.
Last December, over 190 nations paved the way for the emergence of several new market mechanisms under the U.N., and in March the CSI submitted its ideas along with dozens of proposals that negotiators will use to help decide how the markets will work.
The CSI administers a voluntary data scheme where cement companies and trade associations submit CO2 output figures and other production data and eventually pledge their own emission limits. For the first time, firms from China are expected to begin reporting to the scheme within three years after becoming CSI members in 2009.
Fonta said that this year the CSI had admitted three new members to the scheme, one from Mexico and two from India, where 11 firms have pledged to develop an outline for long-term emission reductions by December.

CSI member companies in India, including ACC Limited, Shree Cement Ltd and Ultratech Cement Ltd, and the International Finance Corporation announced signing of cooperation agreements to support low carbon investment in the Indian cement sector.
The IFC’s support has broadened the horizons of the roadmap project. IFC involvement will enable Indian members of the CSI to look at ways in which emissions reduction technologies could be used at their plants, whether that be related to energy efficiency, upgrading technology, material conservation, etc.
The study will be the first to focus on one designated industry in a specific country, which in 2009, CSI produced a global analysis on how the cement sector could reduce its direct emissions 18 percent from 2005 levels by mid-century.

International Cement Review, August 2012
Ten years after publishing its first Agenda for Action in 2002, the CSI has launched its 2012 CSI Progress Report. The organisation takes a look back at the cement industry’s progress towards delivering on this agenda and ahead to the changing business and social environment in which it operates.
“Moving on to the next 10 years, the world will undoubtedly change remarkably again. Nonetheless, the CSI will remain dedicated to leading the cement industry in setting its objectives, achieving its goals, and to remaining at the forefront of sustainable business development,” says CSI managing director Philippe Fonta.
