Listing ID #4143926

Disposal of cow dung is one of the major problem being faced by dairy products producers across the world. Cow dung is not a problem but it is a big asset. There are two ways of processing these to produce Organic Fertilizer.

1. Bio Gas Plant: Here the Biomass is digested in a simple plant and Bio Gas produced is stored and used. The area required for plant is very small.

2. Composting: Here the Biomass is digested underground but Bio Gas is not produced and fuel potential is wasted. It needs large area of land.

A Dairy plant, produces 2.5 to 3 tons of cow dung. If we carefully analyze this waste, we will realize that majority of it is biodegradable. Cow Dung can be converted to valuable organic fertilizer. Generally a slurry of 8 to 10% solids is used in Bio Gas palnt, and one get 350 Kilo Calories per Kg of Cow Dung Cake.

When compared with other organic sources, (manures, oil seed cakes), Cow dung provide aessential elements and thereby promote more harvests from nature.

Disposal of Cow Dung, can be achieved by several other means like incineration, landfills, dumping in the or other water bodies etc. These methods have their own hazards. Incineration can lead to respiratory illnesses. Moreover it may lead to disruption of biochemical cycles of several elements and will have long term effects on biosphere. Landfill and dumping can pollute water bodies.
