Landfill Gas

Definition

Landfill gas is the mixture of gases produced by the decomposition of organic waste in landfills. It primarily consists of methane and carbon dioxide and can be captured and utilized as an energy source.

Analogy

Imagine a landfill as a giant underground compost bin. As the waste decomposes over time, it releases gases just like your compost bin does. These gases can then be collected and used for generating electricity or heat.

Methane Capture: Methane capture involves collecting methane gas emitted from various sources, including landfills, livestock operations, and natural gas systems. This process helps prevent methane from being released into the atmosphere where it contributes to climate change.

Anaerobic Digestion: Anaerobic digestion is a biological process that breaks down organic matter without oxygen present. It produces biogas (including methane) which can be used for energy production.

Renewable Energy: Renewable energy refers to energy sources that are naturally replenished, such as solar, wind, hydro, and biomass. Landfill gas is considered a renewable energy source.
