Different types of Bio-Energy
Biomass    |    Bio-Pellets    |    Bio-Diesel    |    Bio-Ethanol    |    Bio-Oil    |    Bio-Gas
Biomass refers to agriwaste and organic forest residue, which includes wood, wood waste, straw, sugar cane left overs, garden waste and crop residues like baggase, prosopys, cotton stalk, elephant grass, coconut shell etc.  It is a renewable energy source based on the carbon cycle, unlike other natural resources such as petroleum, coal, and nuclear fuels.
Bio-Pellets is a refined and densified form of biomass, which is completely made from agri-waste and organic forest residue. Bio-Pellet industry has considerably grown in Europe in recent years and is gaining importance quickly across the globe due to its carbon neutral properties.
Bio-Diesel is produced from oils or fats using transesterification.  Feedstock for Bio-Diesel include animal fats, vegetable oils, soy, rapeseed, jatropha, mahua, mustard, flax, sunflower, palm oil, hemp, field pennycress, pongamia pinnata and algae. Pure Bio-Diesel is by far the lowest emission diesel fuel. Since Bio-Diesel is an effective solvent and cleans residues deposited by mineral diesel in engine, it also effectively cleans the engine combustion chamber of carbon deposits, helping to maintain efficiency.
Bio-Ethanol is the most common Bio-Fuel worldwide. It is produced by fermentation of sugars derived from wheat, corn, sugar beets, sugar cane, molasses and any sugar or starch that alcoholic beverages can be made from. Ethanol can be used in petrol engines as a replacement for gasoline.
Oils and fats can be hydrogenated to give a diesel substitute. Hydrogenated oils can be blended with diesel in all proportions. Hydrogenated oils have several advantages over Bio-Diesel, including good performance at low temperatures, no storage stability problems and no susceptibility to microbial attack. It is estimated that 19 million tons of oil would be available from biomass by 2020.
Bio-Gas is produced by the process of anaerobic digestion of organic material by anaerobes. It can be produced either from biodegradable waste materials or by the use of energy crops fed into anaerobic digester to supplement gas yields. The solid byproduct can be used as a Bio-Fuel or a fertilizer.
