Sludge for use in cement industries
The Tamil Nadu Pollution Control Board (TNPCB) is exploring the possibility of co-processing the sludge for cement industries, which is being removed from the site where a wall of a Secure Landfill Facility (SLF) collapsed at Ranipet industries. Recently, a wall of the second SLF of a Common Effluent Treatment Plant of Ranipet SIDCO Finished Leather Effluent Treatment Company Ltd, SIDCO Industrial Estate at Ranipet collapsed killing 10 tannery workers and swamping the area with slurry. Officials said they were exploring the possibility of providing the sludge for co-processing to cement industries. The sludge, if it has lime content, can be used in cement production. Else, it can be used as substitute for fuel.
