After carbon dioxide, methane is the most important greenhouse gas emitted by man. Being an odorless and colorless hydrocarbon, it is the main constituent of natural gas and e.g. also of biogas. It is emitted continuously into the Earth’s atmosphere in all kinds of ways. During its relatively brief stay in the atmosphere, its effect as a greenhouse gas is over twenty times more powerful than the most important greenhouse gas released by man, carbon dioxide.

A new method of processing food waste into fertilizer has been outlined in a recent study. The process uses a digester system with microorganisms to break down organic waste into fertilizer. The resultant fertilizer was used in a low-energy greenhouse to produce a range of food crops. The method is a potential way to utilize food waste and reduce the energy consumption of food production as part of a circular economy.
