The technology uses organic materials such as wastewater as input and offers a dual benefit of bioelectricity generation and waste management
Indian Institute of Technology Guwahati has recently developed a bio-electrochemical device, Microbial Fuel Cell (MFC) that can generate green energy by treating wastewater.
The use of organic material such as wastewater in MFC makes it an eco-friendly device that offers a dual benefit of bioelectricity generation and waste management. This research was supported by a grant from the Department of Science and Technology (DST), Government of India.
The research was led by Prof Mihir Kumar Purkait along with his PhD student Mukesh Sharma, Department of Chemical Engineering, IIT Guwahati. They developed a bio-electrochemical device that converts chemical energy contained in organic substrates into electrical energy through microbes.
Commending the work of the research team. Prof T G Sitharam, Director IIT Guwahati, said, “This development has provided an excellent sustainable energy source along with treating several wastewaters. After scaling the process, it can be used as a source of clean energy using municipal wastewater and other such areas economically.”
Explaining the long-term impact of the research Prof Mihir Kumar Purkait, Department of Chemical Engineering, IIT Guwahati, said, “Further implementation of this process may provide an excellent alternative to several costlier renewable energy extraction processes. The conducted study reveals that the prepared CEMs are cheaper and perform better as compared to the several reported membranes, assisting in the separation of charges and potential development.”
The present research of IIT Guwahati is dedicated to synthesising several novel high-performance Cation Exchange Membranes (CEMs) comprising a polymeric blend of several high-end polymers doped with Cellulose Acetate (CA) and other modifiers like Graphene Oxide (GO) to obtain membranes with high Ion Exchange Capacity (IEC) and proton conductivity.
