Centre for Sustainable Technologies (CST)


The Centre for Sustainable Technologies (CST) established as Centre for ASTRA (Application of Science and Technology for Rural Areas) in 1974, is IISc’s inter-disciplinary research and technology development centre for providing sustainable solutions to host of global concerns, primarily dealing with energy, buildings and environment. The Centre’s focus is on promoting Sustainable Technologies tailored to suit local conditions of resource availability and habitation.

Successful examples of CST’s diverse interventions are, Energy Efficient Wood Burning Devices, Biomethanation, Biomass Gasification, Alternative Building Technologies, Green Buildings and BiPV, Water Purification and Defluoridation, Sanitation, Sustainable Biomass for Energy, Forestry, Bioenergy & Climate Change, and Environmental Quality Assurance-Impact Studies. The spread and impact of technologies emanating from CST over the past three decades have been noteworthy; 1.5 million rural households are using the ASTRA wood burning devices for their cooking needs, adoption of biomass gasifiers for village electrification and industries is resulting in a daily savings of about 30 tons of fossil fuel, thirty-five biomethanation plants are converting bio-waste into useful biogas and about 12,000 buildings (including 5000 in earthquake affected regions of Gujarat) have been built using alternate building materials developed at CST. Technologies for defluoridation of water and appropriate tsunami-resistant sanitation systems designed and developed by CST is gaining popularity in the country. Major strides have also been achieved in designing policies for climate change at the national and global level.
