	The '''Kolkata Leather Complex''' is an industrial complex at Karaidanga, [[Bantala]] near [[East Kolkata]], [[India]].<ref>{{Cite web\|title=About – Calcutta Leather Complex Tanners Association\|url=http://calcuttaleathercomplex.in/new_website/about/\|access-date=2020-09-10\|language=en-US}}</ref> It is located 20 km from the central business district of [[Kolkata]] and has an area of about 4.5 square kilometres.

Although the project was to be completed by November 1997. It was later expanded with seven additional components, by February 2010 key systems, such as the Common Chrome Recovery System, solid‑waste disposal unit, and treated‑effluent sump and pumping station, still remained unfinished. [[Central Pollution Control Board]] tests found chromium levels in the plant's sludge at around 25 mg/kg, far exceeding safe limits, and noted poor overall CETP performance. Inspections revealed that chrome‑laden cutting scraps and solid wastes were being dumped roadside rather than processed, posing serious surface and groundwater contamination risks. The ''National River Conservation Directorate'' further criticized both tanneries and the state government for inadequate equipment maintenance, lack of qualified staff, and failure to follow up on recommended environmental safeguards.<ref>{{Cite web \|last=Shiv Sahay \|first=Singh \|date=2011-01-04 \|title=CAG slams govt for failure to complete Bantala plant \|url=https://indianexpress.com/article/cities/kolkata/cag-slams-govt-for-failure-to-complete-bantala-plant/ \|access-date=2025-07-11 \|website=The Indian Express \|language=en}}</ref>

The '''Kolkata Leather Complex''' is an industrial complex at Karaidanga, [[Bantala]] near [[East Kolkata]], [[India]].<ref>{{Cite web|title=About – Calcutta Leather Complex Tanners Association|url=http://calcuttaleathercomplex.in/new_website/about/|access-date=2020-09-10|language=en-US}}</ref> It is located 20 km from the central business district of [[Kolkata]] and has an area of about 4.5 square kilometres.

The complex is intended to serve as a central leather-tanning business for Kolkata.<ref>{{Cite web|title=CSIR-Central Leather Research Institute|url=https://www.clri.org/DepartmentDetails.aspx?DP=339|access-date=2020-09-10|website=www.clri.org}}</ref> Bantala has approximately 500 tanneries<ref>{{Cite news|last=Acharya|first=Namrata|date=2019-07-18|title=Bengal allots 70 acres to 187 new tanneries in Calcutta Leather Complex|work=Business Standard India|url=https://www.business-standard.com/article/economy-policy/bengal-allots-70-acres-of-land-to-187-new-tanneries-in-bantala-leather-hub-119071800775_1.html|access-date=2020-09-10}}</ref> and the Kolkata one performs 22-25% of all the tanning in India.<ref>{{Cite web|date=2017-02-21|title=Our Lust for Leather Comes at a High Price in the Developing World|url=https://undark.org/2017/02/21/leather-tanning-bangladesh-india/|access-date=2020-09-10|website=Undark Magazine|language=en-US}}</ref> The state of [[West Bengal]] is responsible for about 55% of India's leather exports.

The project includes a police station and a fire station; in 2017 the police station was brought under the jurisdiction of the Kolkata police.<ref>{{cite news|url=http://indianexpress.com/article/cities/kolkata/leather-complex-police-station-to-come-under-kolkata-police-4554924/|title=Leather complex to come under Kolkata police|date=5 March 2017|work=The Indian Express|accessdate=26 September 2017}}</ref> The facility also houses the [[Government College of Engineering and Leather Technology]], which is affiliated with [[Maulana Abul Kalam Azad University of Technology]], Kolkata.<ref>{{cite web|url=https://engineering.careers360.com/colleges/government-college-of-engineering-and-leather-technology-kolkata|title=Government College of Engineering and Leather Technology, Kolkata|work=engineering.careers360.com|accessdate=26 September 2017}}</ref> A {{convert|130|acre|ha}} portion was designated as an [[Information technology|IT]] park.<ref name="gowb">{{cite web|url=http://www.banglarmukh.com/BanglarMukh/Download%3FAlfrescoPath%3DDocuments/WhatsNew%26FileName%3DStatus_CLC.pdf|title=Status Report on Calcutta Leather Complex for incorporation in the portal 'Banglar Mukh'|work=Government of West Bengal|accessdate=20 January 2015|url-status=dead |archive-url=https://web.archive.org/web/20130322224916/http://www.banglarmukh.com/BanglarMukh/Download%3FAlfrescoPath%3DDocuments/WhatsNew%26FileName%3DStatus_CLC.pdf |archive-date=2013-03-22}}</ref>

Pumping stations carry the effluent from the tanneries to a [[Effluent Treatment Plant|Common Effluent Treatment Plant]](CETP). Problems in completing the common effluent treatment plant have caused serious difficulties, with [[toxic waste]] polluting the construction activities of some companies.<ref name=Madhupama>{{cite news|last1=Madhupama|first1=Das|title=Leather complex turns threat to environment|url=http://archive.indianexpress.com/news/leather-complex-turns-threat-to-environment/368926/|accessdate=6 October 2014|newspaper=The Indian Express|date=3 Oct 2008}}</ref>

The complex was conceived in the early 1990s as "an integrated complex housing all activities relating to the leather industry in a modern and environment-friendly manner". The need for the project became evident when the [[Supreme Court of India]] ordered that all tanning activities in Kolkata be moved outside the city limits.<ref name = "gowb" />

As of 2013 the complex was still not fully operational, and many illegal tanneries continued to operate outside the complex.<ref>{{cite journal|last1=Roy|first1=Utpah Singha|display-authors=et al.|date=7 March 2013|title=Changes in physicochemical characteristics of wastewater carrying canals after relocation of Calcutta tannery agglomerates within the East Calcutta Wetland ecosystem (a Ramsar site)|journal=International Journal of Environmental Studies|volume=70|issue=2|pages=203–221|doi=10.1080/00207233.2013.774810}}</ref>
