One of the most common variables of the biomass briquette production process is the way the biomass is dried out. Manufacturers can use torrefaction, carbonization, or varying degrees of pyrolysis. Researchers concluded that torrefaction and carbonization are the most efficient forms of drying out biomass, but the use of the briquette ...
Some charcoal briquettes. A briquette (French:; also spelled briquet) is a compressed block of coal dust [1] or other combustible biomass material (e.g. charcoal, sawdust, wood chips, [2] peat, or paper) used for fuel and kindling to start a fire.
Torrefaction is a thermochemical treatment of biomass at 200 to 320 °C (392 to 608 °F). It is carried out under atmospheric pressure and in the absence of oxygen.During the torrefaction process, the water contained in the biomass as well as superfluous volatiles are released, and the biopolymers (cellulose, hemicellulose and lignin) partly decompose, giving off various types of volatiles.

Biomass that is used for energy production can be processed into solid fuels but also into liquid or gaseous fuels. [5]: 173 In comparison, the term biofuel is nowadays mainly (but not exclusively) used for liquid or gaseous fuels, used for transportation. [6] Pellet fuels are made from compressed organic matter or biomass. [7]
From Spring 2015, any biomass owners—whether domestic or commercial—must buy their fuels from BSL (Biomass Suppliers List) approved suppliers in order to receive RHI payments. [72] The Renewable Heat Incentive scandal also referred to as the "cash for ash scandal", was a political scandal in Northern Ireland that centred on a failed ...
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only ...
Straw or hay briquettes are a biofuel substitute to coal. Straw, processed first as briquettes, has been fed into a biogas plant in Aarhus University, Denmark, in a test to see if higher gas yields could be attained. [9] The use of straw in large-scale biomass power plants is becoming mainstream in the EU, with several facilities already online ...
Waste-to-energy technology includes fermentation, which can take biomass and create ethanol, using waste cellulosic or organic material. [17] In the fermentation process, the sugar in the waste is converted to carbon dioxide and alcohol, in the same general process that is used to make wine. Normally fermentation occurs with no air present.
