Biogas is produced by the anaerobic digestion or fermentation of organic matter including cow dong, paddy husk, manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock, under anaerobic conditions.
Its composition can be viewed as follows.
| Matter | % |
|---|---|
| Methane, CH4 | 50-75 |
| Carbon dioxide, CO2 | 25-50 |
| Nitrogen, N2 | 0-10* |
| Hydrogen, H2 | 0-1 |
| Hydrogen sulphide, H2S | 0-3 |
| Oxygen, O2 | 0-2* |
This biogas can be used as fuel for home use, to produce electricity. In Sri lanka and other developing nations use this biogas using community based small scale projects. But this can be used for medium or large scale power or fuel project. Following video will a large scale biogas project which was done by the onsite power system inc.
We are doing biogas project in our university and we had provide biogas for one of canteens in order to reduce their operating cost. It is very small scale project. In our biogas project we use paddy husk & cow dong as inputs.
