Detailed explanation-1: -Biogas consists mainly of methane and carbon dioxide. It can also include small amounts of hydrogen sulphide, siloxanes and some moisture.

Detailed explanation-2: -Biogas is composed mostly of methane (CH4), the same compound in natural gas, and carbon dioxide (CO2). The methane content of raw (untreated) biogas may vary from 40%–60%, with CO2 making up most of the remainder along with small amounts of water vapor and other gases.

Detailed explanation-3: -Biogas has many constituent gases in it. The major constituent gases are methane (40%–70%), CO2 (30%–60%), and other gases such as hydrogen and nitrogen, which are 1%–5% by volume. The major combustible part of biogas is methane (CH.

Detailed explanation-4: -Detailed Solution. Biogas consists mostly of methane (CH4), carbon dioxide (CO2) and a mix of trace gases including nitrogen, hydrogen sulfide (H2S) and others. Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste.

Detailed explanation-5: -Biogas contains roughly 50-70 percent methane, 30-40 percent carbon dioxide, and trace amounts of other gases. The liquid and solid digested material, called digestate, is frequently used as a soil amendment.
