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.

Sustainability with kitchen waste biogas plant

100kg per day KITCHEN WASTE BIOGAS PLANT 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)

NOTE

1. Gas generation rate of 6 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. 10 kg of Manure per day Obtained after drying 200Kg of wet slurry is considered

5. Capacity of a Commercial cylinder is 19kg 6. Transportation costs extra 7. Taxes Extra, as applicable
