1000kg per day KITCHEN WASTE BIOGAS PLANT Waste management is indeed a matter of global concern with the rapid increase in

generation of waste throughout the world. Waste to Energy is an important strategy to address waste management and energy management at one stretch

With Scarcity of Petroleum, increase in cost of LPG is inevitable and waste management is another burning issue of the modern world. A Common solution to tackle both the problems is KITCHEN WASTE BIOGAS PLANT

Kitchen Waste Biogas Plant is a system which transforms the waste from kitchen (biodegradable) to biogas and in the process the manure is formed as a byproduct. Biogas can be utilised for cooking and slurry can be utilised for gardening. It involves the principle of anaerobic digestion through which the complex organic matter is broken down in to simple molecules. Waste Biogas (Product) + Slurry (Byproduct)

Benefits of kitchen waste biogas plant

• A very convenient way to utilise biodegradable waste.

• Clean, hygienic and pollution free environment.

• Free from offensive odour or smell. • No flies, mosquitoes or rats and rodents

problem. • Saving on transportation of waste. • Smoke free fuel can be used for cooking,

in boilers or for electricity generation. • Compact size. • Organic manure as a by product

*NOTE 1. Gas generation rate of 60 m3 per day is Under ideal

conditions 2. 1 m3 of biogas is equivalent to 0.4kg (400g) of LPG 3. Cost of 19kg LPG cylinder is Rs.1856/- which rates LPG at

Rs.97.68/kg, as on April 2012 and price escalation of LPG will change the returns

4. 100 kg of Manure per day Obtained after drying 2000kg of wet slurry is considered

5. Capacity of a Commercial cylinder is 19Kg 6. Taxes Extra, as applicable

Input to the plant 1000 kg of kitchen waste per day

Built up Area 200m2
