الملخص

When organic matter such as food waste or animal waste is broken down by aerobic microorganisms, a flammable gas is produced, which is mostly composed of methane and carbon dioxide, and this process is called anaerobic digestion. This process is now occurring naturally in all garbage dumps scattered in all Libyan cities and contributes effectively to the production of greenhouse gases and thus the process of global warming. In this work, an airtight container was designed to dispose of the household organic waste of one of the Libyan houses and convert it into organic fertilizer and produce flammable gas through the process of anaerobic digestion, the food waste collected from the house of a Libyan family was incubated after grinding it and mixing it with water and cows in a tightly closed container. This container is designed in a way that stimulates and traps gas production and can be used in any Libyan home. Note that this gas burned and flame formed when it was allowed to leave the vessel.
