Biomass<\/a><\/span><\/h2>\n

Biomass is organic matter of vegetable or animal origin. These are (dead or living) bodies of all organisms \u2013 i.e. animals, plants, fungi, bacteria and cyanobacteria. Biomass can be obtained as waste from agriculture, industry, forestry, food industry, such as municipal waste, or arises as the result of deliberate production activities (growing trees and plants). Biomass includes materials such as wood chips, shavings, sawdust, wood waste pellets, briquettes, straw or herbs. <\/span><\/p>\n

Biomass can be «dry» (e.g. wood) or «wet» (e.g. manure — liquid and solid livestock manure mixed with water). The basic processing technology is divided into dry and wet processes. The dry process (thermochemical conversion) includes incineration, gasification and pyrolysis. The wet process (biochemical conversion) includes anaerobic digestion (methane fermentation), alcohol fermentation and the production of bio hydrogen. There is also a special subset of oil extraction and subsequent treatment, which is essentially a mechanical-chemical conversion (e.g. production of biodiesel and natural lubricants).<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
