Cement, Energy and Environment

' l I • A Special Committee has been constituted to deal with the procedure aspects for the permissions and speedy disposal of cases for trial run of wastes. The Board also granted permissions for trial co-processing of wastes in to cement plants and also pursued the matter with the CPCB for the permanent permissions. In furtherance, to boost up the Co-processing of Municipal Solid Waste (MSW I RDF) in cement Kilns GPCB has drawn attention of all Municipal Corporations/ Local bodies and also various State level meetings, Seminars were organized. Extended Green Node The Extended Green Node (XGN) is an e– governance web - based tool developed by GPCB wi th the support of National informatics Centre (NIC), Gandhinagar. On XGN, a platform is developed to disseminate the details of hazardous waste generation and its utilization. It also keeps track of the waste being loaded, transported using GPS based hazardous waste tracking system, online monitoring of pollution parameters and wastes recycled/ incinerated/ disposed off at TSDF. Some Statistics of Wastes utilized as AFR in the State • 2<009-10 (15693 MiU) 2013-14 (543569 MT) 111 2.0HH1 (22345 r•.n:t Vearwise % of Wastes ut ilized as AFR- Gujarat Figure 3: Year wise % of wastes co-processed: Gujarat A big Showcase: Expanded Utilization of Wastes via Co-processing in Gujarat GPCB has granted Authorization I permission to M/s. Ambuja Cement, Gujarat, M/s Ultratech Cement, Gujarat, M/s.Sanghi Cement Ltd. Gujarat and M/s . Lafarge India (P) limited , Chhattisgarh for co-processing of different type of Hazardous Wastes in line with regular permission accorded by CPCB, Delhi. Board has also accorded permission to Paper Mil ls of Vapi region for disposal of the Plastic waste for co-processing in various Cement Industries. Some statistics of various types of wastes utilized as Alternate Fuel and Raw materials are as per Table-1. Toxic and high calorific wastes which earlier being disposed off through incinerators of the State now diverted to Cement kilns reducing emission of green house gases, emission of dioxin/ furan and operating cost of incinerators. Wastes which possess characteristics suited for secured landfilling at TSDF now channelized to Cement kilns either mixed with other wastes or after preprocessing to make up calorific values needed. Some of wastes which are very high in volume but less hazardous which otherwise disposed in haphazard manner in and around industrial units/ estates are also being utilized as raw materials in cement plants resulting a win- win situation by saving for ecological, aesthetical and economical balances of Cement plant as well as of the State. 7
