Chicken Waste Bio-Diesel

Chicken Waste Bio-Diesel: John Abraham, a veterinary doctor-turned-inventor, on July 7, 2021, finally received the patents for inventing biodiesel from slaughtered chicken waste.

Highlights:

  • The Indian Patent Office finally granted him the patent for inventing “biodiesel produced from rendered chicken oil” after seven-and-a-half years.
  • Mr. Abraham works as an associate professor at the Wayanad veterinary college under the Kerala Veterinary and Animal Sciences University.
  • The patent was delayed as permission from the National Biodiversity Authority was needed because the key raw material going into the patented invention was a biological material locally sourced.
  • At present, Mr. Abraham and three of his students are working on developing biodiesel from pig waste.

Background:

  • During 2009-12, Mr. 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 (who 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.
  • After his research, Mr. Abraham joined the Pookode Veterinary College, near Kalpetta in Wayanad, and in 2014 he set a ₹ 18-lakh pilot plant at the college campus with funding from the Indian Council for Agricultural Research.
  • In 2015, the Kochi Refinery of Bharat Petroleum had issued a quality certificate for the biodiesel that was invented by him and since then the vehicle of the college was running on this biodiesel.

Why chicken waste was used to invent this biodiesel?

  • The chicken waste was used to invent this biodiesel because birds and pigs have a single stomach which offers higher fat saturation and this is easy to render oil under room temperature.

Benefits of Chicken waste biodiesel:

  • 1 liter of biodiesel can be produced from 100 kg of chicken waste.
  • It offers over 38 kmpl and can be sold at 40 percent of the diesel price.
  • The higher mileage and lower pollution are due to the fact that chicken waste contains 62 percent fat, offering the key energy content of Cetane at 72, while in normal diesel it is only 64.
  • It also increases engine efficiency by 11 percent due to the presence of more oxygen and reduces smoke levels by over 47 percent.
  • The high Cetane value of 72 in animal fat bio-diesel leads to shorter ignition delays, providing more time for fuel combustion, leading to more efficiency and less exhaust emission
  • On the blending side, he said, for old diesel engines his biodiesel can be blended at a ratio of 80:20, while for new CDREi engines, it is the reverse–20:80.
