7th -8th July, 2016, Mellacheruvu, Telangana: The 2nd Workshop on ‘Promoting Exchange of Best Practices in the area of Energy Efficiency in Cement Sector’ was organized on 7th-8th July, 2016 at Mellacheruvu, Telangana. The workshop was hosted by My Home Industries Limited and organized under the Knowledge Exchange Platform (KEP) initiative. KEP is a joint initiative of Bureau of Energy Efficiency (BEE) and Institute for Industrial Productivity (IIP) to promote energy efficiency by facilitating exchange of knowledge, experiences and best practices in industries covered under the Perform Achieve and Trade (PAT) scheme.
The workshop was inaugurated by Shri Ashwani Pahuja, Director General, National Council for Cement and Building Materials. In his inaugural address, he congratulated BEE and IIP for establishing the Knowledge Exchange Platform, which will assist the industries to share ideas and best practices. He mentioned that India is the second largest producer of the cement in the world and has adopted sustainability initiative. He mentioned the industry may enhance the usage of renewable energy and waste heat recovery in-order to reduce the energy cost. Sector has been in a position to reduce its GHG emissions from a level of 1.12 ton CO2 emissions per ton of cement in late 1990’s to 0.72 recently. Still there is significant potential to reduce GHG emissions by incorporating cleaner technologies. He informed the participants that BIS have released the standards for composite cement, which may bring down the clinker factor to 0.35 in comparison to 0.70 in case of PPC manufacturing, which means only half the quantity of energy intensive clinker would be required in comparison to PPC. Shri Pahuja hoped that this platform will support the work being undertaken by the industries in the area of energy efficiency and to explore additional channels for the promotion of cleaner technologies.
Welcome address and introduction to the workshop was delivered by Shri K K Chakarvarti, Expert Consultant, Bureau of Energy Efficiency. He provided an update on KEP initiatives and mentioned that in order to ensure that KEP continues to act as a forum for sustain interaction within and across industry sectors, it is important that KEP’s efforts are strengthened by providing continuous input and feedback. He informed that besides initiating sectoral workshop, quarterly newsletter, best practice exchange visits, KEP has also developed an interactive website (www. knowledgeplatform.in). He mentioned that KEP intends to develop this website as a strong tool in promoting not only the KEP activities but also as a one stop solution to all the information needs of the industry. Shri Chakarvarti concluded his welcome address by stating that focous of KEP in its second year of operation is assess the technology gap and promote energy efficient technologies in the PAT Sectors.
Shri Naren Pasupalati, Commercial Diplomacy Officer – Energy, Climate and Growth Unit, British High Commission in his address gave an overview on BHC’s role in supporting and assisting India’s initiatives in the area of energy efficiency.
