Cement, Energy and Environment

Kapur sums it up. AFR mission has to be encouraged by government, society, business entities and individuals. Let us not forget cement plants are best disposal of hazardous wastes. It serves mother earth , humanity at large and therefore economical in long run and has to be achieved in collaboration of all stakeholders. Waste to wealth- and that is the way to go. Agith G Antony THRUST AREAS TO PROMOTE THE USE OF RDF • Declare waste to energy as a renewable source of energy • Amendment in MSW and HWM rules and inclusion of co-processing in cement kilns as a preferred disposal option • Development of operational guidelines for transportation , storage, and handling of waste • Suitable market mechanism for promotion of co-processing • Creation and formalisation of waste hierarchy to direct waste with good heating values for co-processing • Promote waste segregation and pre– processing • Develop collaboration between local municipal corporation and cement plants, regular supply of MSW for RDF, capacity building of municipal corporations. • Information on availability and quality of waste Reducing the C0 2 Footprint -The Road Map India is the world 's fastest growing cement market with increasing demands giving rise to fast pace infrastructure development. The Indian cement industry has made strong efforts to reduce its carbon footprint being the most efficient in the world. Yet, because the manufacturing process relies on the bur.~ing of limestone (calcium carbonate), it produced 137 mt of carbon dioxide (C0 2 ) in 2010 - approximately 7 per cent of India·s total man-made C0 2 emissions. To further reduce C0 2 emissions and achieve sustainability, International Energy Agency (lEA) and Cement Sustainability Initiative (CSI) in collaboration with the Confederation of Indian Industry (CII} and the National Council for Cement and Building Materials (NCB) have developed a low carbon technology roadmap specifically for the Indian cement industry as part of their global initiative. Under this new roadmap, Indian cement industry has set a target of halving its carbon emissions to 0.35 tonnes (t) of C0 2 /t cement in 2050 , about 45 per cent lower than current levels to support the global goal. The roadmap development was spear-headed by the three co– chair companies, ACC, Shree Cement and UltraTech, who committed extensive resources and expertise from across their companies to lead the project. Key Findings • Reduction of total C0 2 em1ss1ons to an industrial average of 0.719 tonne (t) of C0 2 /t cement in 2010 from a substantially higher level of 1.12 t C0 2 /t cement in 1996 • C0 2 emissions are projected to reach between 488 mt C0 2 and 835 mt C0 2 by 2050 if suitable technologies and measures are not adopted. This represents a 255 per cent to 510 per cent increase compared to current emissions • The technologies, policy frameworks and investment needs outlined in this roadmap could reduce C0 2 intensity in the Indian cement industry by about 45 per cent by 2050, from the 2010 level • The milestones for the Indian cement industry set out in this roadmap would enhance energy security by saving between 377 petajoules (PJ) and 485 PJ of energy in 2050 compared to a business-as-usual scenario • The additional investment required in the Indian cement industry (based on net present value) to achieve the C0 2 emissions reduction set out in this roadmap is between $29 billion and $50 billion ('145,000 crore and '250,000 crore), or 15 to 25 per cent higher than in a business-as-usual scenario • The roadmap also outlines key levers to attain energy efficiency by increasing use of blended cements, alternative fuels and raw materials, widespread implementation of waste heat recovery (WHR) systems, alternative energy sou rces, research and development, etc. Courtesy: Indian Cement Review from Internet 52
