The content of the report falls under five categories : co-processing of alternative fuels and raw materials, improved thermal and electrical efficiency, clinker substitution, waste heat recovery and newer technologies such as nanotechnology. The technical papers aim to identify, describe and evaluate technologies, which may contribute to increased energy efficiencies and reduced greenhouse gas emissions from cement production in India today and in the longer-term. The results have been reviewed by CII, NCB, CSI member companies and stakeholders like the International Energy Agency (IEA). All papers follow the same format, outlining the current status of the technology, the impact on energy consumption, anticipated benefits from implementation, the CO reduction potential, main parameters influencing implementation, cost estimation, and the conditions, barriers and constraints of implementation. For the more futuristic technologies, where quantification is difficult, a qualitative summary is provided instead, indicating those technologies felt to be promising for future implementation and emissions reductions potential. In these papers, only the anticipated impact on energy consumption and barriers to further development can be shown. In every paper, a range of potential thermal and electrical savings is provided; this range has been reached through consultation with technical experts.
