On 17 December 2018, Experimental Test Pilots and Test Engineer from IAF's premier testing establishment ASTE, flew India's first military flight using blended bio-jet fuel on the An-32 transport aircraft. The project is a combined effort of IAF, DRDO, Directorate General Aeronautical Quality Assurance (DGAQA) and CSIR-Indian Institute of Petroleum.
On 27 July 2018, Air Chief Marshal BS Dhanoa, Chief of Air Staff had announced IAF's intention to promote biojet fuels.
