Greetings! You have landed on the homepage of Swachh Lab.
We are a research laboratory located at the Indian Institute of Technology Kanpur in the Sustainable Energy Engineering department.
We develop chemical and material-based technological solutions aiding towards sustainability and decarbonisation. Our research interests include:
Clean air - including carbon capture, direct air capture, and gas separation technologies.
Clean chemicals - including catalysis, CO2 conversion, power-to-fuel, and waste-to-wealth technologies.
Clean water - including wastewater treatment, and PFAS removal technologies.
Further details are found in the Research section.
We value the power of academic-industrial collaborations for lab-to-market technological translations. Please get in touch with Sayan with any queries regarding this or for consultation.
