What is Biodigester?

There are different types of biodigester in use. The widely used model is the fixed dome digester buried under the ground. The fixed dome biodigester consists of digester with a fixed nonmoveable gasholder,which sits on top of the digester. In this biogas process,a source of renewable energy is generated such as methane(CH4),bio-slurry,gas for cooking,lightening and much more.

The estimated costs of biodigeter depend on different sizes:
Biodigester size (m3) Total cost (US$) Subsidy from NBP (US$) Farmer  cost (US$) Use of biogas stove duration (Hour) Use of biogas lamp duration (Hour)
4 550 150 400 2 - 4 8 - 16
6 620 150 470 4 - 6 16 - 24
8 720 150 570 6 - 8 24 - 32
10 800 150 650 8 - 10 32 - 40
15 1100 150 950 10 - 15 40 - 60

Digested slurry from biodigester is the top natural fertilizer consisting in general of 93% water, 7% dry matter of which 4.5% is organic and 2.5 % is inorganic matter. In addition to the major plant nutrients, it also provides micro-nutrients such as zinc, iron, manganese and copper that are also essential for plants but required in trace amounts.
