Biogas is a form of renewable energy produced during the anaerobic digestion process. This energy source is created when organic matter like food scraps, biosolids and animal waste are broken down in an oxygen-free vessel. It includes methane, carbon dioxide, and some traces of hydrogen sulfide and siloxanes. Ultimately, it depends what kind of waste is placed into the reactor vessel prior to the anaerobic digestion process.
What Can Biogas Be Used For?
Biogas can be used for a wide variety of purposes. Typically, it is converted into electricity, heat, vehicle fuel, and renewable natural gas. Biogas can also be used to generate energy products and biochemicals. It is also sometimes referred to as compost gas and marsh gas.
During the anaerobic digestion process, digestate is also produced. Digestate refers to any liquid and solid materials left behind after the digestion process. This can also be transformed into organic fertilizer, animal bedding, building materials, and crop irrigation products.
A Short History of Biogas

Believe it or not, biogas has been produced for thousands of years. Today, we take a technologically advanced approach to anaerobic digestion, but it is a naturally occurring process. In fact, the production of biogas is said to have first begun in 3,000 B.C in the Middle East. During this time, biogas was used to warm bathing temperatures. The first large-scale AD system was developed in Bombay in 1859. In the past, biogas has been used to light streetlamps and treat wastewater. According to the American Biogas Council, over 2,000 facilities across all 50 states in the U.S. now produce biogas. These facilities utilize anaerobic digestion systems, stand-alone digesters, landfill gas projects and more.
What Are the Advantages of Anaerobic Digestion (AD) and Biogas Production?
When biogas is produced via anaerobic digestion, it can be applied as a renewable energy source. Therefore, it supports the environment and helps companies build a sustainable future. Some additional benefits of anaerobic digestion and biogas production include:
- Limit greenhouse gas emissions (GHG). When biogas is used, less methane is released into the atmosphere. This, in turn, limits dependence on fossil fuels. Natural gas that is produced from biogas limits greenhouse gas emissions by up to 91% compared to petroleum gasoline.
- Diversified farm revenue. Anaerobic digestion systems allow you to recycle energy and create animal bedding, organic nutrients, and energy sources. Ultimately, these byproducts can be used on the farm or sold. As a result, there is extra income streams and revenue diversification.
- Economic Growth in Rural Areas. Anaerobic digestion systems require workers, typically in rural communities. Giving workers dependable jobs boosts the economy and supports local communities. Additionally, growth is a catalyst for attracting more growth, helping transform regions into thriving economies.
- Agricultural Conservation. AD systems limit run-off as well as the spread of viruses and contagions. As a bonus, they enrich soil by altering nutrients and making them more consumable and healthier for plants.
- Reduced Energy Dependence. If you own a business, you know how much energy it takes to operate. With anaerobic digestion, you can produce your own source of energy like biogas. If you’d like, you can even supply extra energy to your local grid.
