Renewable Natural Gas (RNG) is a type of gas that is produced from organic materials, such as food waste, agricultural residues, and animal manure. It is created through a process called anaerobic digestion, where microorganisms break down these materials in the absence of oxygen. This process generates biogas, which can be purified to remove impurities and converted into RNG, making it a clean energy source. RNG can be used in the same way as conventional natural gas, powering vehicles, heating homes, and generating electricity. By utilizing waste materials, RNG helps reduce greenhouse gas emissions and promotes a more sustainable energy system.
