Green Technology Developed By IIT Guwahati To Generate Green Energy By Treating Waste Water

Guwahati: In bid to move towards harnessing renewable and sustainable energy, The Indian Institute of Technology Guwahati (IIT-G) developed a bio-electrochemical device which can generate green energy by treating wastewater. The technology is called Microbial Fuel Cell (MFC) which uses organic material like waste water for its functioning.Also Read – IIT Madras Develops Algorithm to Protect Air Traffic Control From Attacks

According to the news agency IANS, the IIT-G sources on Wednesday said that the use of organic material such as waste water in MFC makes it an eco-friendly device that offers a dual benefit of bioelectricity generation and waste management.

The bio-electrochemical device converts chemical energy contained in organic substrates into electrical energy through microbes, a statement of the institute said. The conducted study revealed 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 research, supported by a grant from the Department of Science and Technology (DST) of the Central government, was led by Prof. Mihir Kumar Purkait, along with his PhD student Mukesh Sharma of the Department of Chemical Engineering. Commending the work of the research team, Prof T. G. Sitharam, Director IIT-G said that 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,” said Sitharam.

Rapid population growth has led to rising energy demands and environmental concerns, necessitating the development of renewable and sustainable energy production techniques.

Along with several renewable energy sources (solar energy, wind energy, tidal energy, and geothermal energy, among others), the sustainable energy sources also include the ‘Blue Energy’ sources of energy harvesting and these sources of energy have no negative impact on the environment.

The waste sugarcane bagasse has also been used in the study to improve the membrane performance, thereby preparing a valuable product from the agricultural waste.
