1. “Development &
Performance evaluation of a 3 KW biogas based power generation system utilizing
Lignocellular Biomass”, at IIT-Guwahati. Under this project, a 5 HP
gasoline engine’s operating parameters
have been optimized for modifying a
gasoline SI engine into 100% biogas fuelled SI engine. 16 m3 of biogas produced per day from
lignocellulosic feed stock materials mainly cow dung, rice straw, duck weed and switch grass and a 3 kWe biogas power
generation unit integrated with solar assistance backup system has been
successfully installed and maintained by IIT Guwahati at Auaniati Satara, North
Guwahati, Assam under this project. A center for demonstrating the
potential of power generation by using raw biogas have been successfully
established and this is becoming a training and knowledge center for local
entrepreneurs and dairy farms to gather technical information for generating
Off-grid power. All the objectives of the
assigned project are achieved and the final report of the project completion
has been received.
2. “Development of
Hybrid-High rate bio-methanation reactor using locally available media for
treating waste water and solid waste” at Tamil Nadu Agricultural
University, Coimbatore (Tamil Nadu) has been completed. Under this project,
three lab scale hybrid reactors fabricated with acrylic sheet one of which
served as control and the other two reactors with different packed media. The
stability of the reactors attained with affluent pH of 7 to 7.5 and the biogas
production observed 250-300 ml in each reactor. The performance evaluation of
high rate reactor and hybrid high rate reactor with community wastewater was
completed and HRT optimized. The Project Completion Report has been submitted.

In order to
provide a sustainable solution for avoidance of in–field burning of paddy straw
stubble in northern Indian states, a research project was awarded by MNRE
entitled “Development of suitable pre-treatment system for paddy straw
disintegration for biogas generation leading towards commercialization of
technology” to the Indian Institute of Technology, Delhi entitled “Development of
suitable pre-treatment system for paddy straw disintegration for biogas
generation leading towards commercialization of technology” by Centre for
Rural Development and Technology, IIT, Delhi. In the project a laboratory scale hydrothermal reactor was developed for
pre-treatment of paddy straw at different temperature and reactor loading
rates. Further, a field scale hydrothermal reactor having 50 L capacity was
fabricated for performing field scale experiment for performance evaluation of
the model. The detailed analysis of energy consumption of the hydrothermal
pre-treatment process by the reactor used in the study has been done. Further
plan of work is to reduce energy demand in the hydrothermal pre-treatment
process of paddy straw, experiments on loading of more than 20% TS will be
studied in details for energy consumption as well as biogas production
potential in larger size of anaerobic reactors. The biggest advantage of hydrothermal pre-treatment is high reduction in
hydraulic retention time required for biogas production, which is 20–25 day
only instead of somewhere 100 days for untreated paddy straw.
