Soon after India attained independence in 1947, the first government of the country led by Jawaharlal Nehru focused on industrialisation. As a part of that, several research laboratories and institutes, such as National Physical Laboratory in New Delhi, National Chemical Laboratory in Pune, National Metallurgical Laboratory in Jamshedpur, Fuel Research Institute in Dhanbad, Central Glass and Ceramic Research Institute in Kolkata, were set up across the country. On 24 April 1948, the then Central Minister of Industry and Supply Dr. Syama Prasad Mookerjee laid the foundation stone in the Guindy region of Chennai.

In the same year, the institute took up a pilot activity to produce biodiesel from rice bran oil. In 2014 CLRI Scientists launched website to conveniently share real research problems and solutions in research. Notable people from the institute
