The biodigester technology degrades and converts human waste into usable water and gases. The generated gas is used for cooking and water for irrigation purposes. This is done in an eco-friendly manner.

What is the working of bio digester technology?

The biodigester technology involves bacteria that feed upon fecal matter. The fecal matter is dumped into a tank along with the bio digesting bacteria. The bacteria through anaerobic process will degrade the fecal matter. During the process water and methane gas are released.

What is an anaerobic process?

It is the process that occurs in the absence of free or combined oxygen.
