MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202611061446 A) filed by Birla Institute Of Technology And Science, Pilani on May 14, 2026, for An Electrobiomethanation Reactor To Treat Undiluted Organic Waste And Method For Electrobiomethanation Of Said Waste.
Inventors include Prof. Sankar Ganesh Palani; Sarva Sai Nikhilesh Gantala; Pavithra Pari; Prof. Nicky Eshtiaghi; and Dr. Maazuza Othaman.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: The invention relates to electrobiomethanation (EBM) reactor to treat undiluted organic waste comprising: a reactor vessel; an electrode system comprising at least two carbon-based electrodes, each electrode coated with a metal; a power supply unit; a feed system; and a gas collection system. The invention also provides a method for electrobiomethanation of undiluted organic waste comprising the steps of: (a) adding an inoculum of microbial consortia for anaerobic digestion into the EBM reactor of claim 1 containing undiluted organic waste feedstock such that the ratio of the feedstock to the inoculum is in the range of 75:25 to 85:15; (b) regulating hydrolysis of the feedstock by maintaining electron transfer through applying a voltage of 0.3 to 0.8 V to the electrodes; and (c) controlling pH of the feedstock during anaerobic digestion in the range of 4.5 to 6.0 through oxidation of volatile fatty acids (VFAs) generated.
