Carbon dioxide (CO2) is the most prevalent greenhouse gas that traps heat and raises the global temperature, contributing to climate change. Rough estimates suggest over 30 billion tonnes of CO2 being released annually into the atmosphere. With Tamil Nadu becoming increasingly urbanised with installation of many power plants and booming textile industry, researchers hope their new invention can be a turning point towards a low-carbon future.
Three years of research and hard work and scientific approaches on samples collected from power plants and textile dye industries went into finally converting CO2 into useful products like bricks and bicarbonate.
K Palanivelu, director, Centre for Climate Change and Adaptation Research, Anna University, told Express that technology can be adopted by major polluting industries like coal-fired power plants, steel and aluminium manufacturing firms to ensure there is zero discharge of CO2 into the atmosphere. The project report has been submitted to the Union government and the university is ready to transfer the technology to the industry. The research project is funded by Department of Science and Technology (DST), New Delhi.
