Location: APMC, Surat

 

Biogas CNG Plant at Kodoli Kolhapur

          Developed on a BOOT (Build, Own, Operate and Transfer) basis

      Daily capacity of approximately 100 tons, or 35,000 annual tons, of sugarcane waste (pressmud).

              Daily production of approximately 7,000 to 9,000 kg’s of Bio-CNG per day

      PESO (Petroleum and Explosives Safety Organization) License for storage and filing of Bio-CNG in high pressure cylinders

       Daily production of organic manure/soil conditioner after further processing for commercial sale

       NOCA (National Organic Certification Association) approved organic manure for further sale to farmers

       MNRE (Ministry of New and Renewable Energy) approved investment subsidy received in early 2013

          Substantial cost savings for industrial customers due to low-cost Bio-CNG use  

      Climate friendly CO2 negative: Biogas-to-CNG conversation is the most productive use of agricultural waste

      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 40% carbon dioxide and trace amounts of hydrogen sulphide. This biogas produced is further processed so that the carbon dioxide and hydrogen sulphide gases are removed. The result is a gas consisting of mostly methane.

 

 

 

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
