Alkali lignin
Lignin obtained by acidification of an alkaline extract of wood Anaerobic digestion (AD): is a biological process similar in many ways to composting.
Anaerobic digester
A reactor that is constructed to effect the degradation of organic matter by anaerobic bacteria.
Anaerobic digestion
The degradation and stabilisation of organic materials brought about by the action of anaerobic bacteria with the production of biogas (bio-methanisation).
Capable of being broken down biochemically by the action of micro-organisms.
A mixture of methane (CH4) and carbon dioxide (CO2) produced by anaerobic digestion, with small amounts of other gases. The methane is a flammable gas, chemically identical to the main constituent of natural gas, and can be used as a fuel for heat and/or electricity generation.
Any plant-derived organic matter.
Biomass Processing Residues
By-products from processing all forms of biomass that have significant energy potential.
Is a general term for all the biological methods used for the production of methane biogas.
Small fragments of wood chopped or broken by mechanical equipment. Total tree chips include wood, bark, and foliage. Pulp chips or clean chips are free of bark and foliage.
Combustion is the best known and probably the most efficient form of converting solid biomass to steam or electricity.
Energy from Waste
Energy derived from waste products such as most bioenergy like biofuels, biomass, biogas.
Largely organic material fed into a digester, including solid and liquid wastes.
Gasification of Biomass
Gasification is a process that converts carbonaceous materials, such as coal, petroleum, biofuel, or biomass, into carbon monoxide and hydrogen by reacting the raw material, such as house waste, or compost at high temperatures with a controlled amount of oxygen and/or steam.
One of the botanical groups of dicotyledonous trees that have broad leaves in contrast to the conifers or softwoods.
Herbaceous energy crops
Perennial non-woody crops that are harvested annually, though they may take 2 to 3 years to reach full productivity.
The major noncarbohydrate, polypenolic structural constituent of wood and other native plant material that encrusts the cell walls and cements the cells together.
A colourless, odourless, flammable gas and a main constituent of biogas; chemical formula CH4.
Municipal waste
Residential, commercial, and institutional post-consumer wastes contain a significant proportion of plant-derived organic material that constitutes a renewable energy resource.
Producer gas
The mixture of gases produced by the gasification (BECGasification) of organic material such as biomass at relatively low temperatures (700 to 1000C).
If organic matter is heated with insufficient oxygen to support combustions, the resulting action is called pyrolysis.
Byproducts from processing all forms of biomass that have significant energy potential.
Short rotation forestry
Trees and other types of lignocelluloses materials specifically grown for brining biofuels and mass by the choice of appropriate species, sites, planting densities and harvesting schedules.
Generally, one of the botanical groups of trees that in most cases have needle-like or scale-like leaves; the conifers; also the wood produced by such trees.
a solid lignocellulosic material naturally produced in trees and some shrubs, made of up to 40%-50% cellulose, 20%-30% hemicellulose, and 20% -30% lignin.
