What is Biogas?
Biogas is a renewable fuel that is naturally produced from organic waste, commonly manure or food waste. Biogas is an important fuel type for many reasons as it is a renewable resource, unlike many other fossil fuels, such as coal, oil, and natural gas. Using fewer fossil fuels leads to reduced greenhouse gas emissions for planet earth.
Converting waste into energy, it must go through the natural process of anaerobic digestion. Simply put, breaking down waste in a closed space. This process results in the creation of methane and CO2. The CO2 is removed, leaving methane to be used as a renewable natural gas. This process leads to another advantage of using biogas, of less water and soil pollution. This process often occurs in a digester tank, meaning there will not be any chemicals being leached into soil or water. Digester tanks can be found at biogas upgrading plants, which concentrate the methane in biogas to natural gas standards.
Another byproduct of biogas is organic fertilizer, which means even less chemicals being used. Arguably the greatest advantage, producing biogas is low-cost if any cost, considering all the payoffs. Manure and food waste will continue to be produced at massive amounts and be readily available.
Benefits of using biogas
Renewable & Clean
Reduces the use of fossil fuels and greenhouse gas emissions.
Waste can be used as biogas.
Manure and food scraps will always be available.
The materials being used (manure, food, etc.) are already being produced and there are low-cost biodigesters on the market.
