PROCESS TECHNOLOGY UPGRADATION IN PALLAVARAM TANNERIES
The tanneries in Pallavaram area during the initial period of operations adopt different types of processes such as chrome tanning, vegetable tanning, raw to finish, semi-finish to finish operations, etc.
- During the period 1980-2000, due to the pollution problems in and around Pallavaram, Pammal and Chrompet area, mainly due to the discharge of high saline water, odour, TDS, etc., the tanneries reduced the raw to semi-finish operations and established the CETP during 1990-1995.
- From the year 2001 onwards, the pre-tanning (i.e. beam house) operations such as soaking, liming, removal of fleshing, deliming etc. have been totally discontinued by the tanneries in Pallavaram cluster to reduce the liquid and solid pollution discharges. The main chrome tanning process is also totally discontinued to control Chromium discharge in the effluent. The total pollution load in terms of BOD, COD, SS, etc., which are reduced by about 60-70%, and the TDS are reduced by about 70%.
- The tanneries in Pallavaram Cluster process only semi-finish to finished leather. The semi-finish leather (i.e. wet blue and vegetable tanned leather) is received from all parts of India and other countries.
- PTIETC-SPV is authorized to carry out the other required roles and responsibilities for the successful completion of the Upgradation of Pallavaram Tanners Industrial Effluent Treatment Company (PTIETC) and Dilution project for TDS Management and dilution system is under successful operation.
- For further upgradation of our CETP, financial support under STEP sub-scheme of IFLDP 2021-26, Government of India accorded approval for the project proposal submitted by PTIETC for a total project cost of Rs 52.61 Crores vide Sanction order F.No.P-27015/6/2024-Leather Dated:30/6/2025 , Ministry of Commerce & Industry , DPIIT Government of India- Grant details-:- DPIIT Assistance (70%) GoTN Assistance (15%) CETP Contribution (15%)
