After waiting for more than seven years, John Abraham, a veterinary-doctor-turned-inventor, has finally received the patents for inventing biodiesel from slaughtered chicken waste that offers mileage of over 38 km a litre at around 40 per cent of the current price of diesel and lowers pollution by half.

After seven-and-a-half years, the Indian Patent Office finally granted us the patent on July 7, 2021, for inventing 'biodiesel produced from rendered chicken oil', Abraham, an associate professor at the veterinary college here under the Kerala Veterinary & Animal Sciences University, told from Wayanad.

The invention is an outcome of his doctoral research at the Namakkal Veterinary College under the Tamil Nadu Veterinary & Animal Sciences University.

During 2009-12, Abraham pioneered research on producing biodiesel from the slaughter waste of broiler chicken and dead poultry birds. He completed the research under the guidance of the late Prof Ramesh Saravanakumar (passed away awaiting the patent in November 2020), who had filed for the patents in 2014 on behalf of the Tamil Nadu Veterinary & Animal Sciences University, Abraham said.

After his research, Abraham joined the Pookode Veterinary College, near Kalpetta in Wayanad, and in 2014 he set a Rs 18-lakh pilot plant at the college campus with funding from the Indian Council for Agricultural Research.
