Recycled waste to be used as fuel at cement plants | CPCB draft guidelines

The Central Pollution Control Board (CPCB) has issued draft guidelines, which mentions that hazardous, municipal and agricultural waste should be recycled and used as fuel in cement plants. The draft ‘Guidelines for Pre-processing and Co-processing of Hazardous and Other Wastes in Cement Plants’ as per Hazardous and Other Waste (Management and Transboundary movement Rules) 2016 were opened to public last month for comments.
 
Aimed at ensuring that the waste is recycled in order to help tackle pollution, the proposed guidelines are in line with the recently notified hazardous waste rules 2016. As Ulhas Parlikar, Director, Geocycle, says, “The earlier rules were different; in fact, co-processing was not a part of the rules at all. It was only recognised as ‘use of hazardous waste’ under rule 11.” He adds that it is after eight years of experience of co-processing in the country, the rules have been modified: “It suggests that all materials, which are suitable for co-processing should be permitted for co-processing without any trial.” While earlier conditions included the need for a trial, CPCB’s experience derived from about 90 odd trials conducted concluded that these don’t add much value. Additionally, Parlikar says positively, “CPCB has introduced these guidelines to facilitate state government authorities; basically, for the State Pollution Control Boards (SPCBs) to understand and interpret the rules accurately and grant necessary authorisation or undertake co-processing in a proper manner.” 

This move would also benefit cement companies. As Parlikar shares, “First, companies will be able to dispose waste, which is not recyclable. Also, importantly, since waste will be processed and used, utilisation of natural resources – be it raw material or fuel – will reduce. That said, cement players may also reduce mining activities, and to a large extent production cost, because using waste will be less expensive as a natural material.” That said, this will also result in considerable reduction of carbon footprint.
