Cement Energy and Environment

crushability, process and maintenance impact, handling, homogenization (as the alkali and fluoride content may vary) , storage (any storage under open sky or without sealed paved ground is not acceptable for disposal of SPL) and safety aspects are some of the key concerns of cement industry. He mentioned that securing the regular use permit from CPCB is a very lengthy and time consuming process which can sometime take 10 to 12 months' time, needs to be resolved . Mr. Jain also emphasised on the need for Aluminium industry to pay at least the minimum tipping fees for disposal of SPL in cement industry. Mr. Jain mentioned that the concept co-processing in cement industry has already been proven as one of the most reliable option for disposal of SPL and cement plants in Europe, Australia, Latin America are regularly using SPL as an alternative fuel. However in the Indian context, the utilization of SPL as an alternate fuel is almost absent, where he emphasised on the need for action on part of aluminium industry and Regulators. 14. Second presentation was made by Mr. S. Katiyar, Sr. Vice President and Mr. U.S. Chaudhary, General Manager, Dalla Cement. They mentioned that their plant is presently co– processing different non-hazardous waste as well as hazardous waste in its cement kilns. In their recommendation, they highlighted the need for the waste generators to take the primary responsibility for waste disposal and requested CPCB to ease the process and lead time for granting permission for use of hazardous waste. 15. Last presentation in this panel was made by Ms. Momuita Chakraborty from Geocycle. She mentioned that Geocycle has access to 14 facilities of ACC and Ambuja Cement, where they are promoting co-processing of wastes. Ms. Chakraborty informed that as per Hazardous Waste Management Rules, 2008, the conventiona l methods of SPL disposal are Secured Storage Land filling (SLF) for refractory portion and Incineration for carbon portion of SPL (as GCVis more than 2500 kcal/kg). None of the Indian aluminium smelter plants have captive incinerator. Unsound SPL management is a risk to the environment, in particular to the ground water and the health of people. She said that cement plants can help in handling SPL in a safe way. She shared the information on how Holcim plants are co-processing SPL globally. Informing the participants about their initiatives in India, she mentioned that they have a MoU with BALCO,Vedanta Limited for conducting SPL trial at Ambuja Cement Limited , Bhatapara (Chhattisgarh). In these trails, they have to follow CPCB protocol for emission monitoring and ensure high safety standards. They have also developed vendors for crushing SPL at BALCO's site, and till now they have crushed close to 1000 T for trial purpose. 16. The presentations by panelists was followed by discussion between participants, where they highlighted the need for (i) promoting innovative models of partnership between the two sectors, (ii) developing a mechanism for cost sharing between the two sectors in a way that makes it viable for cements industry to co-process SPL, and (iii) work with Regulators (CPCB & state PCBs) to ease the approval process to conducting trails, work out emission standards and facilitate intra and inter– state transfer of SPL. The representatives of both sectors agreed to the suggestion given by Mr. S. K. Wali of constituting a Task Force with representation of both sectors and other key stakeholders like the Regu lators and policy makers. 17. Mr. K. K. Chakarvarti, Expert Consultant, BEE, conveyed thanks to Mr. S. K. Wali for Chairing the session and the panelists for their presentations . He assured that KEP will take necessary steps to constitute a Task Force, as proposed by Mr. Wali and endorsed by the participants. He requested the representatives of both the sectors to send nominations for the Task Force so that KEP can facilitate its constitution and development of time bound action plan. The creation of a Task force can go a long way in resolving some of the long standing issue for promoting co-processing of SPL in cement kilns. PANEL DISCUSSION 2: National and International Technologies for SPL Utilization 18. The second panel discussion was focused on sharing the experiences of national and international technologies available for detoxification of SPL and supporting its use in cement and other industries. This panel was Chaired by Dr. Mukesh Kumar, President, Head Group Technology, Vedanta Limited. Setting the tone for discussion, Dr. Kumar in his opening remarks, mentioned that SPL which is presently being treated as waste, is a precious energy 62
