Any time organic materials (like food scraps) decompose, they can be expected to produce methane and carbon dioxide.

Anaerobic organisms exude smelly gas as a byproduct of their exertions. With this process, microorganisms break down organic matter, such as food scraps, in an airtight container, over a relatively long time. For example, black-colored digesters or garbage bags absorb solar heat, and burying underground provides better heat insulation. Advantages of Anaerobic Digestion It is a net energy-producing process that produces renewable energy in the form of biogas.
