Biogas and BioDiesel

Biogas commonly refers to a mixture of various gases formed by the disintegration of organic matter in the absence of oxygen. Biogas can be manufactured from raw matters such as agricultural waste, municipal waste, manure, plant material, green waste, and sewage or food waste. Biogas is a renewable energy source and in diverse cases exerts a limited carbon footprint. Biogas can be manufactured by fermentation of biodegradable materials or anaerobic digestion with anaerobic organisms, which disintegrates material inside an isolated system. Biogas is basically methane (CH4) and carbon dioxide (CO2) and may have small traces of hydrogen sulfide (H2S), siloxanes and moisture.

Biodiesel indicates an animal fat-based or vegetable oil diesel fuel comprising of long-chain alkyl (methyl, ethyl, or propyl) esters. Biodiesel is customarily made by chemically reacting lipids (e.g., soybean oil, vegetable oil, animal fat (tallow)) with an alcohol generating fatty acid esters. Biodiesel is suggested to be utilized in standard diesel engines and is thus well-defined from the vegetable and waste oils used to operate fuel converted diesel engines. Biodiesel can be used singly, or blended with petrodiesel in any proportions. Biodiesel blends can also be utilized as heating oil.
