Cement Energy and Environment

Events Brief Low Carbon Technology Partnerships initiative The World Business Council for Sustainable Development {WBCSD), organized an Action2020 Climate Dialogue at lTC Maurya, New Delhi on 14th September 2015 as part of a series of such dialogues in the run up to COP21 in Paris. The dialogue focussed on Low Carbon Technology Partnerships Initiatives (LCTPi), and included a session on Cement LCTPi conducted by Cement Sustainability Initiative (CSI). An overview of the deliberations in the Cement Session follows : 1.0 Cement LCTPi India ambition is upto 20% reduction of C02 emissions in 2030 compared to Business As Usual (excluding CCS and Captive power generation). The industry recognizes that in order to achieve this level of ambition as a sector there needs to be availability of financing , policy reform and technology transfer. At the same time, awareness and capacity building of society at large needs to be ensured for acceptance of new products and solutions. 2.0 The key levers to achieve this ambition were identified as: 1. Increasing clinker substitution in the cement ii Enhancing energy efficiency iii. Increasing use of alternati ve fuels and raw materia ls (AFR) iv. Development of new products, technologies and carbon capture and utilisation The group identified the various policy, financing and technology barriers for each lever. They also listed action areas to address the barriers, working in close collaboration with the different stakeholder groups involved. The findings are summarised below: 3.0 Reduction of clinker factor The following barriers were identified to reduce clinker factor: Qual ity and quality variation of f lyash I granulated blast furnace slag Lead distance from producer of fly ash I GBFS to user of the same High cost of slag lead distance Higher energy requirement for slag grinding Pollution issues when special additives I admixtures are added Challenges for improving the pond ash quality No incentives/benefits for PPC I PSC Product Standards needed for Composite cements Portland Limestone Cement Cement containing multiple other additives
