Biomass and Biofuels

This category contains non-commercial scientific, educational, and governmental references to biomass and biofuel. Biomass is organic non-fossil material. It comprises the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes into substances such as coal or petroleum. Solid biomass comes in different forms including what comes directly from the “producers” (grass, trees, shrubs, crop husks, etc.) and that which comes as waste from the animals that consume the producers (droppings or dung from animals and waste from humans). Biofuel is any fuel that originates from biomass. The three classes of biomass used for combustion are solid (e.g. wood, dried plants and animal waste), liquid (e.g. ethanol, methanol and vegetable oil) and gaseous (e.g. bio-methane and hydrogen).

This category is intended for non-commercial scientific, educational, and governmental references to biomass and biofuel. Before submitting a site to this category or its subcategories, be sure to read the related descriptions. Failure to submit to the most specific and appropriate category can delay the consideration of your submission. Information on energy itself, but not primarily relating to renewable energy technologies, belongs in the main category on Science/ Technology/ Energy. Further, content for conferences, organizations and publications should be submitted to the appropriate category which can be found from the top level of Energy at Science/ Technology/ Energy. Some educational sites might be better listed in Kids_and_Teens/ School_Time/ Science/Environment/ Renewable_Energy/ or Science/ Technology/ Energy/ Education/. Please compare categories and choose the most appropriate for your submission. Commercial sites that have substantial scientific or non-commercial informational content might be listed here however, please review categories under Business for potentially more appropriate categories before you submit. See for example: Business/ Energy_and_Environment/ Renewable and the category description Information on renewable energy itself, but not primarily relating to biological energy technologies, belongs in the main category on Science/ Technology/ Energy/ Renewable/, not under Biomass and Biofuels.

Biodiesel

Biodiesel is liquid fuel manufactured from vegetable oils, animal fats, recycled restaurant grease, and similar materials. This category is for sites about biodiesel technology.

Ethanol

Ethanol is a clean-burning, high-octane fuel that is produced from renewable sources. At its most basic, ethanol is grain alcohol, produced from crops such as corn. Because it is domestically produced, ethanol helps reduce America's dependence upon foreign sources of energy. Pure, 100% ethanol is not generally used as a motor fuel; instead, a percentage of ethanol is combined with unleaded gasoline. This is beneficial because the ethanol: * decreases the fuel's cost * increases the fuel's octane rating * decreases gasoline's harmful emissions Any amount of ethanol can be combined with gasoline, but the most common blends are E10 (10%) and E85 (85%)

Vegetable Oil Fuels

Waste vegetable oil (WVO) is vegetable oil that is recycled, typically from restaurant fryers and is used in diesel engines. Most users reclaim WVO from their local restaurants for free. Many users of this fuel modify their engine compartment to provide heating for the WVO or SVO to decrease its viscosity. Straight vegetable oil (SVO) is vegetable oil that has never been used. Biodiesel is not the same as SVO or WVO, but it can be made from both through a chemical reaction.

Wood Combustion

This category contains non-commercial, scientific, educational, and governmental references to renewable forms of energy derived from wood.
Emphasis is on sustainable culture of trees as a source of biomass and biofuel,: the technology behind ecologically efficient production, and; maximising the energy obtained, with or avoiding direct combustion, such as the generation of Wood Gas.

Please suggest sites to this category only if they are non-commercial, scientific, educational, and governmental references to technology for producing energy from wood.

Before submitting a site to this category, be sure to read the related descriptions. Failure to suggest to the most specific and appropriate category can delay the consideration of your submission.
