Ranipet, a town about 120 kms from chennai has a large concentration of tanneries processing hides and skins from raw to finish. Born out of the urgent need to control pollution, several centralized treatment facilities were planned. The Ranipet Common Effluent Treatment Plant (RANITEC) at V.C.Mottur,Walajapet is one of such successful facilities catering to the needs of 92 tanneries.

The plant is designed to handle about 4500 cum/day of effluent, making it one of the largest Common Effluent Treatment Plant (CETP) for tannery wastewater in the country. Since its establishment in the year 1995, the CETP has been constantly upgraded with either partial assistance or matching grant from the Government of India and Tamil nadu.

Some of the unique features of this treatment facility are:

  • India’s first CETP to achieve the highest International Standard for Quality - the ISO Standard. RANITEC CETP achieved ISO 9001 Certificate on 15th November 1999 and is currently ISO 9001:2015 Certified Company by DNV, The Netherlands.
  • World first RANITEC CETP in leather sector to achieve the highest International Standard for Environmental Management System - the ISO Standard. The CETP has achieved ISO 14001 Certification on 29th January 2014 and is currently ISO 14001: 2015 certified by DET NORSKE VERITAS (DNV), The Netherlands.
  • The formation of Waste Minimization Circles with support of Central Leather Research Institute (CLRI) has created awareness among the CETP member tanners and resulted in reducing the usage of water consumption in the processes of tanning to 28 litres/Kg in compliance.
  • Implementation of Zero Liquid Discharge (ZLD) System of the CETP by a Special Purpose Vehicle formed in the name and style "Chennai Environmental Management Company of Tanners" (CEMCOT).
