Investigations on acceleration of biomethane production from crop residues at high solids concentration and at mesophilic and thermophilic temperatures by using micronutrients

The presence of micronutrients (trace metals) and their bioavailability influence the anaerobic process significantly and with proper dose of metals in combination rate and yield of biogas generation can be increased substantially. The preliminary studies carried out at SPRERI indicate that biogas generation can be accelerated by use of trace metals and a systematic investigation is necessary for establishing optimum use of metal concentration for increasing gas generation. It is planned to investigate effect of trace elements on biogas generation from crop residues like rice straw, sugarcane trash and wheat straw at high solid concentration.


Development of fully mechanized, biphasic system for production of biogas and manure from vegetable market waste in large towns

Biphasic technology to convert vegetable market waste has been successfully demonstrated through the year long operation of 3 T/day plant designed and installed near Anand town. Two such plants of 10 T/day capacity each have been planned for Ahmedabad and Jalgaon. The technology will be scaled up and fully mechanized to utilize 50-100 T/day vegetable waste for producing fuel gas and compost in large towns where the problem of disposal of such waste is most severe.


Pilot scale studies on biomethanation of delignified agroresidues

Agro-residues contain about 35-40% of cellulose, 20-25% of hemicellulose and 10-20% of lignin as major constituents. Lignin entraps the cellulose and hemicellulose portion, which makes them unavailable for anaerobic digestion. For  efficient biomethanation the delignification of agro-residues is essential. SPRERI has successfully experimented on delignification of banana stem and biomethanation of the delignified material at laboratory and pilot scale. It is planned to carry out experiments on biological degradation of lignin content of wheat straw and to develop a pilot scale thermophilic anaerobic system to process delignified wheat straw to produce methane and manure. 


Conversion of biomass into fuel quality ethanol

It is proposed to evaluate different pretreatments and enzymes for hydrolysis of  biomass and identify the most suitable combination in terms of efficiency, cost and energy balance, which can replace acid hydrolysis. it is further proposed to develop techniques for economic utilization / safe disposal of the residue and effluent from the conversion processes. 


Producer gas / biogas fuelled power systems

It is planned to develop producer gas / biogas fuelled power systems in the range of 10 kW to 1000 kW using SPRERI's biomass conversion systems to produce these gases having favorable characteristics and quality for use as CI engine fuel.


Development of pilot scale fluidized bed gasifier and cyclone gasifiers.

The investigative studies on fluidized bed gasifiers and cyclone gasifiers will be intensified and the information generated will be utilized to develop pilot scale systems to evaluate and demonstrate these for thermal and power applications.


Biomass management and preparation for energy purpose

Comprehensive study will be done of the season and location specific availability of biomass; its characteristics and quality; most appropriate equipment and process to harvest , collect, densify, handle and transport the biomass; its storage requirements; and equipment and processes to pre-treat the biomass to make it suitable as feed stock for energy purpose.


Integration of solar thermal and photovoltaic devices in the design of residential, commercial and community buildings.

It is proposed to work on the integration of solar water heaters, air heaters and photovoltaic panels in the design of different types of buildings.
