Phytrogas is a term that typically refers to a type of biofuel derived from plant materials, specifically through processes like anaerobic digestion or gasification. It primarily consists of methane and other gases produced by the decomposition of organic matter. Phytrogas is considered a renewable energy source, as it helps reduce waste and can contribute to a more sustainable energy system. Its production and use can help mitigate greenhouse gas emissions compared to fossil fuels.
