How much does it cost to maintain a biogas plant?
Operating costs The annual operating and maintenance costs for the digester and end-use equipment are approximately $25,000. End uses for the methane gas produced include electricity generation, which is sold to the local utility, and use of waste heat to heat the digester.
How is biogas production measured?
Biogas volume was measured using a 1,000-ml syringe. The syringe was connected to the reactors by injecting the needle through the butyl bung, then drawing the plunger out until the pressure in the headspace dropped to ambient pressure. The volume of gas in the syringe was taken as a measurement of the gas produced.
Why biogas plant is not popular?
An unfortunate disadvantage of biogas today is that the systems used in the production of biogas are not efficient. There are no new technologies yet to simplify the process and make it accessible and low cost. This means large scale production to supply for a large population is still not possible.

What is Kvic biogas plant?
KVIC type biogas plant This mainly consists of a digester or pit for fermentation and a floating drum for the collection of gas. Digester is 3.5-6.5 m in depth and 1.2 to 1.6 m in diameter. There is a partition wall in the center, which divides the digester vertically and submerges in the slurry when it is full.
