Short Rotation Forestry
Short rotation forestry (SRF) is grown as an energy crop for use in power stations, alone or in combination with other fuels such as coal. It is similar to historic fuelwood coppice systems. Species used SRF is the practice of cultivating fast-growing trees that reach their economically optimum size between 8 and 20 years old. Species used are selected on this basis and include alder, ash, southern beech, birch, ''Eucalyptus'', poplar, willow, new varieties of ''Paulownia elongata'', paper mulberry, Australian blackwood and sycamore. Planting and harvesting Trees are planted at widths that allow for quick growth and easy harvesting. They are usually felled when they are around 15 cm wide at chest height, this takes from 8 to 20 years. This compares with 60 years or more for standard forestry crops. When felled, SRF trees are replaced by new planting or, more usually, allowed to regenerate from the stumps as coppice. The wood chip produced by SRF is preferred in the power i ...

Energy Crop
Energy crops are low-cost and low-maintenance crops grown solely for energy production by combustion (not for food). The crops are processed into solid, liquid or gaseous fuels, such as pellets, bioethanol or biogas. The fuels are burned to generate electrical power or heat. The plants are generally categorized as woody or herbaceous. Woody plants include willow and poplar, herbaceous plants include '' Miscanthus x giganteus'' and ''Pennisetum purpureum'' (both known as elephant grass). Herbaceous crops, while physically smaller than trees, store roughly twice the amount of CO2 (in the form of carbon) below ground compared to woody crops. Through biotechnological procedures such as genetic modification, plants can be manipulated to create higher yields. Relatively high yields can also be realized with existing cultivars. However, some additional advantages such as reduced associated costs (i.e. costs during the manufacturing process) and less water use can only be accompli ...

Sycamore
Sycamore is a name which has been applied to several types of trees, but with somewhat similar leaf forms. The name derives from the ancient Greek ' (''sūkomoros'') meaning "fig-mulberry". Species of trees known as sycamore: * ''Acer pseudoplatanus'', a species of maple native to central Europe and southwestern Asia * ''Ficus sycomorus'', the sycamore (or sycomore) of the Bible; a species of fig, also called the sycamore fig or fig-mulberry, native to the Middle East and eastern Africa * ''Platanus orientalis'', chinar tree (Old World sycamore) * Some North American members of the genus ''Platanus'', including ** ''Platanus occidentalis'', the American sycamore ** ''Platanus racemosa'', the California sycamore or western sycamore ** ''Platanus wrightii'', the Arizona sycamore ** ''Platanus mexicana''. the Mexican sycamore * In Australia, there are numerous trees which have the common name "sycamore": ** ''Litsea reticulata'' or ''Cryptocarya glaucescens'' (silver sycamore) ** ''P ...

Wood Fuel
Wood fuel (or fuelwood) is a fuel such as firewood, charcoal, chips, sheets, pellets, and sawdust. The particular form used depends upon factors such as source, quantity, quality and application. In many areas, wood is the most easily available form of fuel, requiring no tools in the case of picking up dead wood, or few tools, although as in any industry, specialized tools, such as skidders and hydraulic wood splitters, have been developed to mechanize production. Sawmill waste and construction industry by-products also include various forms of lumber tailings. The discovery of how to make fire for the purpose of burning wood is regarded as one of humanity's most important advances. The use of wood as a fuel source for heating is much older than civilization and is assumed to have been used by Neanderthals. Today, burning of wood is the largest use of energy derived from a solid fuel biomass. Wood fuel can be used for cooking and heating, and occasionally for fueling steam engi ...

Short Rotation Coppice
Short rotation coppice (SRC) is coppice grown as an energy crop. This woody solid biomass can be used in applications such as district heating, electric power generating stations, alone or in combination with other fuels. Currently, the leading countries in area planted for energy generation are Sweden and the UK. Species used SRC uses high yield varieties of poplar and willow. Typically willow species chosen are varieties of the common osier or basket willow, ''Salix viminalis''. Poplar is generally planted for visual variation rather than being a commercial crop, although some varieties can outperform willow on suitable sites. Species are selected for their acceptance of varying climate and soil conditions, relative insusceptibility to pests and diseases, ease of propagation and speed of vegetative growth. To combat pests such as brassy and blue willow beetles, as well as the fungal pathogen ''Melampsora'' (a rust), planting a carefully selected mix of varieties is recomme ...

Nonfood Crop
A nonfood crop, also known as industrial crop, is a crop grown to produce goods for manufacturing, for example fibre for clothing, rather than food for consumption. Purpose Industrial crops is a designation given to an enterprise that attempts to raise farm sector income, and provide economic development activities for rural areas. Industrial crops also attempt to provide products that can be used as substitutes for imports from other nations. Diversity The range of crops with non-food uses is broad, but includes traditional arable crops like wheat, as well as less conventional crops like hemp and Miscanthus. Products made from non-food crops can be categorised by function: See also * Biofuel * Bioplastics * Biopolymer * Cash crops * Cellulosic biofuel * Energy crop * Food vs fuel * Helix of sustainability * Intensive crop farming * National Non-Food Crops Centre * Renewable Energy Renewable energy is energy that is collected from renewable resources that are natu ...

Energy Forestry
Energy forestry is a form of forestry in which a fast-growing species of tree or woody shrub is grown specifically to provide biomass or biofuel for heating or power generation. The two forms of energy forestry are short rotation coppice and short rotation forestry: *Short rotation coppice may include tree crops of poplar, willow or eucalyptus, grown for two to five years before harvest. *Short rotation forestry are crops of alder, ash, birch, eucalyptus, poplar, and sycamore, grown for eight to twenty years before harvest. Benefits The main advantage of using "grown fuels", as opposed to fossil fuels such as coal, natural gas and oil, is that while they are growing they absorb the near-equivalent in carbon dioxide (an important greenhouse gas) to that which is later released in their burning. In comparison, burning fossil fuels increases atmospheric carbon unsustainably, by using carbon that was added to the Earth's carbon sink millions of years ago. This is a prime contributor ...

Bioenergy
Biomass is plant-based material used as a fuel for heat or electricity production. It can be in the form of wood, wood residues, energy crops, agricultural residues, and waste from industry, farms, and households. Some people use the terms biomass and biofuel interchangeably, while others consider biofuel to be a ''liquid'' or ''gaseous'' fuel used for transportation, as defined by government authorities in the US and EU. The European Union's Joint Research Centre defines solid biofuel as raw or processed organic matter of biological origin used for energy, such as firewood, wood chips, and wood pellets. In 2019, biomass was used to produce 57 EJ (exajoules) of energy, compared to 190 EJ from crude oil, 168 EJ from coal, 144 EJ from natural gas, 30 EJ from nuclear, 15 EJ from hydropower, hydro and 13 EJ from wind power, wind, solar power, solar and geothermal energy, geothermal combined. Approximately 86% of modern bioenergy is used for heating applications, with 9% used for tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon Sequestration
Carbon sequestration is the process of storing carbon in a carbon pool. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop land into land for non-crop fast growing plants. Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, enhanced weathering, direct air capture and water capture when combined with storage. Forests, kelp beds, and other forms of plant life absorb carbon dioxide from the air as they grow, and bind it into biomass. However, these biological stores are considered volatile carbon sinks as the long-term sequestration cannot be guaranteed. ...
