The focus of my laboratory is on Sustainable Development Goals with major emphasis on Clean water Sanitation, Zero hunger, Affordable & Clean Energy, Climate Action and Responsible consumption and production.

 We are part of Global Sanitation Graduate school ( offering ME in Sanitation Science Technology & Management, M.Tech in Sanitation Science Technology and Management for Working Professionals, Minor Programme in Water and Sanitation and Postgraduate Certificate in Non Sewered Sanitation for working professionals. 

Our Faecal Sludge Management Laboratory is part of Global Partnership of Laboratories for Faecal Sludge Analysis,the%20methods%20and%20obtained%20results.

Through our research projects we demonstrated single household vertical wetlands based domestic wastewater treatment, single household empowered septic tank for domestic wastewater treatment, 100 people equivalent empowered septic tank for domestic wastewater treatment. The advantage of these treatment systems are their cost effectiveness / affordability. For example, our 100 people equivalent treatment system operating costs is Rs 176 per day (total operating costs) whereas just the chlorination cost in a conventional treatment system is Rs 300 per day.


Our other projects focuses on anaerobic digestion of different wastes like we had put a horizontal plug flow reactor which could handle 1 ton of food waste per day. It is operational since 2010 and the output biogas is either burnt or supplied to cafeteria. We also are partners in demonstrating  an anaerobic digester (currently under construction) for 10 tons of food waste and 20 tons of septage in Nashik. We also provided consultancy for building an anaerobic digestor in Madgaon Municipal market which handles 700kgs of vegetable waste and 300kgs of fish waste.


Energy should not be the focus at the expense of soil fertility. Our project focuses on Terra preta sanitation (a type of compost), Phosphate rich organic manure and Struvite production for improving soil fertility. We are using the above mentioned composts / organic fertilizers to see improvement in crop productivity in selected villages in Pimpalner district of Maharashtra. Currently we are testing them on Bengal Gram, Onion and Wheat for the Rabi season. We will test it on other crops as well on summer crops and Kharif crops.


Our other works focuses on biodegradation of pollutants like paracetomol, crude oil / tar balls, enzyme production from different wastes, optimization of chemical oxygen demand procedure for sea water, Carbon dioxide sequesteration using microalgae. 


Without collaborations, research will be incomplete. Our collaborators are IISc Bengaluru, IIT Kharagpur, NIT Surathkal, INRA Narbonne – France, Ecole de mines Nantes – France, Ghent University - Belgium, Caltech – USA, Technical University Hamburg Harburg - Germany, GIZ – Germany, International Water Management Institute Colombo - Srilanka, Cranfield University – UK, Georgia Tech, USA.

Presently collaborating with 6 countries.

Start ups – Three start ups from this lab.

Sustainable Biosolutions LLP started by two of our former M.E Biotech students. They are into wastewater treatment by sequencing batch reactors. They had installed successfully few plants in Goa since their start in 2013. The wastewater treatment plant of the biggest mall in Goa i.e Mall de Goa was installed by them.

Another start up Bactreat Environmental solutions LLP was started by me which focuses on Wastewater treatment, bioremediation and resource recovery. This company has bagged three successive projects from DBT BIRAC for its project on Resource Recovery from Septage project and implemented wastewater treatment systems for households, apartment complexes and schools.

15% stake in Zycon Pvt Ltd.
