Secure landfill

2. IPR Status

Patent/Copyright/Trademark secured in Indian/Abroad

IPR Details

Indian Patent No.264075

3. Application/Uses For secure storage of chemical sludge generated from Common Effluent Treatment Plants (CETPs) and Effluent Treatment Plants (ETPs). This secure landfill finds enormous potential applications for eco-friendly secured disposal of sludge and solid wastes.


Secure landfill (SLF) for disposal of solid and sludge comprises rigid, monolithic, impermeable, horizontal and vertical liner to prevent leakage of leachate from landfill. Significant amount of solid wastes are generated by several processing industries such as chemicals, leather, textile etc. The structure of the present invention may be used for the secured disposal of these solid wastes. Moreover, the structure may also be used as a secure landfill to dispose the sludge generated from industrial effluent treatment plants.

Secure landfill not only enhances the waste holding capacity by 3 times but also improvises the limitations associated in current practice in liner system. Horizontal liner is integrated with plurality of crests and troughs for collection of leachate in vertical direction. Arranging an array of troughs sloping towards sidewall not only enhances the leachate collection rate but also reduces the length of travel of leachate.

5. Level/Scale of Development Implemented in full scale for tannery sector

An improved process for making retanned leather with dyeing effect



IPR Details

Indian Patent application no. 129NF2015

3. Application/Uses Single step process for retanning and dyeing


Chemically modified black liquor in the manufacture of syntans or fillers is well known, but there are no reports on the direct utilization of black liquor without any chemical modifications in leather processing. Therefore, there exists a dire need to provide improved process for preparing retanned leather using black liquor without any chemical modification and providing a single step option for retanning-cum-dyeing of leather, where dyeing is achieved using natural material, which is non-hazardous in comparison to the conventional synthetic dyes.

5. Level/Scale of Development Lab and pilot scale trials were carried out.

Chrome-Melamine syntan



IPR Details


3. Application/Uses In addition to rechroming, filling of the looser portions like belly is possible now


Many of the finished leather manufacturers source their wet blue leathers from various regions or tanners. In order to have uniformity of metal oxide content, almost all the leathers are rechromed. For this, the industry employs masked chromium(III) salts provided by the leather auxiliary industry in the form of complexes co-linked to phenol/ naphthalene condensates. Also, tanners who use hides/skins from ill fed animals treat their tanned substrate with melamine condensates, so as to get a preferential filling of the belly region. Metal ion complexes co-linked to melamine condensates are rather scarce. For the first time, chromium-melamine condensate devoid of formaldehyde as cross linker has been . The said product has been employed in rechroming and evaluated for multiple properties such as providing an equalization of chrome content and filling of belly region. Our studies clearly indicate a marked advantage of employing such a product in the place of commercial chrome syntans alongside melamine condensates, more so for ill fed cow hides.
