Biogas is generally made from what?

Answer and explanation

Correct answer: Organic waste

The governing concept is anaerobic decomposition of biodegradable organic matter. Biogas is commonly produced in a digester when microorganisms break down materials such as animal dung, food scraps, sewage, and other plant or kitchen waste in the absence of oxygen. The gas usually contains methane, which can be burned as a fuel, and carbon dioxide. This process also supports waste management by converting some waste into useful energy and digestate. Plastic toys, glass bottles, and iron rods are not suitable biodegradable feedstock, so option C is correct.
