In partnership with India’s largest sugar producer, Bajaj Hindustan Limited, SREL converts approximately 30,000 to 50,000 tons of pressmud
annually into renewable energy and organic manure/soil conditioner.
Step 1: Conversion of Organic Waste into Biogas
Step 2: Biogas Conversion into Bio-CNG
Step 3: Organic Manure/Soil Conditioner Use and Storage
Organic, biodegradable waste, or feedstock (pressmud), enters the system for digestion where an anaerobic process using bacteria ferments the wastes and produces biogas as a gaseous bi-product. Several times a day, waste, fresh water and recycled water (over 30% water is reused during plant operations) is fed into digesters, which serve to treat the feedstock, eventually turning it into biogas consisting of mostly methane, as well as carbon dioxide and hydrogen sulphide.
The biogas produced at our plant will contain approximately 60%
to 70% methane, 30% to
By using compressors in our bottling plant, the methane and carbon dioxide gases will be stored under high pressures in cylinders. These gases can then be utilized in industrial applications, for fuel in vehicles, electrical power generators and for other heating purposes. With an onsite combined heat and power (CHP) unit, electrical power generation is also viable. The Warana Bio-CNG project will be using a portion of the gas for auxiliary power consumption to run the plant. The waste heat from the CHP unit will also be used to maintain the temperature of the digesters.
Thee remaining non-digestible solids exit the digester in the form of a liquid slurry. The liquid slurry is further processed by a separator where solids (dry) are separated and sold as a soil conditioner.
The liquids from the separation process is sold to local farmers and the remaining portion is stored in an adjacent storage lagoon and eventually recirculated back into the digesters with the feedstock at the beginning of the anaerobic digestion process.
The liquid Bio-fertilizers (LBF) are suspensions having useful microorganism, which fix atmospheric nitrogen and solubilize insoluble phosphates and potash mobilize and make it available for the plants LBFs have a shelf life of minimum one year, with no health hazards to production workers and are easy to transport.
Additionally, LBF can be used in drip irrigation and as a component of organic farming.
Bio-fertilizers are broadly categorized in three ways as Nitrogen Fixing, Phosphate mobilizing, and organic matter decomposers Thus they are eco-friendly as compared to chemical fertilizers
