Biogas Plants for Auto & Industrial Fuel (CBG Plants)
What if you were told that you could get free fuel to run your car and travel as long as you want? Sounds too good to be true? Not with biogas!
If you can harness or cultivate biogas, you can create fuel for automobile and industrial usage. Ready to know how it all works? Read on!
Mailhem is a waste management company that specializes in biogas plants and offers a renewable energy source to many companies across the country. Biogas is basically a gas that’s produced by decomposing organic matter in the absence of oxygen. This occurs due to the fermentation of biodegradable materials like manure, sewage, green waste, plant material, municipal waste and crops. The production of biogas occurs either naturally (where garbage or waste is decomposing) or it is engineered by creating an oxygen-less environment for the decomposable organic matter. Mailhem excels in the engineered production of biogas using the anaerobic digestion method.
All About Anaerobic Digestion for CBG
Anaerobic Digestion generates Biogas which can be purified and converted into Compressed Biomethane, also called Compressed Biogas (CBG). CBG can be used as fuel for transportation or industries. The Government of India’s initiative has made biogas plants exempt from excise duty and eligible under Corporate Social Responsibility and 80% depreciation is admissible. Our Anaerobic Digester is a combination of Continuous Stirred Tank Reactors( CSTR) and Modified Up flow Anaerobic Sludge-Blanket (M-UASB) technology.
Mailhem’s Anaerobic Digester offers efficient management of waste and results in stabilized bio-manure. Successful use of biogas technology can also provide other benefits like the production of bio-fertilizer, social and ecological benefits including sanitation, reforestation and reducing the reliance on fossil fuels.
The suitable material for anaerobic digestion includes segregated organic waste, Poultry Waste, Pressmud, Cowdung, Agro waste like Paddy Straw, Napier Grass, Slaughterhouse waste, Food Waste, etc.
Recently, the Government of India has launched the SATAT Policy. SATAT means Sustainable Alternative Towards Affordable Transportation, and is a developmental effort that will benefit vehicle users as well as farmers and entrepreneurs. It will help in efficiently handling municipal solid waste as well as other types of organic waste management and also aims at tackling the problems of air pollution caused by farm stubble burning and carbon emissions. Under this policy, CBG can be sold at Rs. 46/kg to the oil marketing companies.
When biogas is used as a fuel, the purity specifications are stricter than those in case of electricity or heat recovery. Biogas as a fuel must contain a minimum of 96% methane and the vapour content must be less than 15 mg/Nm3. For this, the process involves compression at 15–20 bars, desulfurization and decarbonisation using water scrubbing with a loss of 8% of methane. Next, there’s a dehydration process using pressure system absorption followed by dehalogenation and finally compression up to 250–350 bars.
Compared to diesel fuel, the advantages of using biogas are tremendous and the economic benefits are worth a lot more.
If you have some organic waste and need fuel, Mailhem has the solution for you! Mailhem can be your long-term partner for these kinds of projects.
