Thepelletsit's abiofuelobtained from compressed organic matter. Is the pellet harmful? No! The pellet is not harmful and does not contain glues of any kind. On this page we will seehow to produce pellets at homeand how pellets are obtained in the widest industrial chain.
How the pellets are produced
On an industrial level, thepellets are producedstarting from agricultural residues, waste from the wood industry and virgin wood.
At home, thepelletsYesproducesstarting from wood, sawdust or wood chips.
Thepelletsis produced bymechanical compressionof the woody material that is first passed through amill(a millstone).
The mechanical compression is operated by a press, in which the ground wood reaches high temperatures. It is due to the high temperatures that thepelletstakes on that shiny, almost plastic surface!
In reality it is not about plastic but aboutlignin, the lignin contained in the wall of the plant cell flakes off acting as a natural glue. The pellet production process is shown in the video below.
The biomass thus ground and pressed passes through holes of specific dimensions (the dimensions range from 6 mm to 8 mm, depending on the request for pellets). When thepelletscools is ready to be bagged and distributed for retail.
Environmental impact of pellets
Thepelletsnot only is it not harmful but it is also good for the environment when compared with other types of fuels.
According to a research published in 2009, carried out by the Chemistry Department of the University of Bologna in collaboration with the Clean Energy Research Center of the University of British Columbia, thepelletsit's good for the environment even if it comes from overseas!
Research has estimated that the energy consumed to shippelletsCanadian wood from Vancouver to Stockholm (covering 15,500 km via the Panama Canal) represents only 14% of the total energy yield of the pellet load.
Based on the moisture content of thepelletswe can estimate the energy yield. The higher the calorific value of the pellet, the higher the quality of this biofuel. The high-quality pellets burn cleanly and give off high doses of heat. For all information on how to produce pellets of good quality we refer you to the page:pellets, quality and certifications.
How pellets are produced at home:homemade pellets
Who are you wondering how to produce pellets from wood or how pellets are produced at home, you need to know three preliminary factors:
- to produce a large amount of pellets, a machine known as a pellet mill is required.
- To produce pellets it is necessary to have available space; a large garden or a spacious garage.
- To produce pellets you need to have a good amount of plant matter available.
For the purchase costs of the pellet mill, please refer to the page:domestic pellet machine, prices.Those lucky enough to live in the countryside can accumulate mowing materials during spring and summer and leave them to dry naturally in the sun. Mowing materials (pruning branches, suckers ...), inserted in a good pellet machine, can return somehomemade pelletsof great quality. The pellet machines allow you toproduce pellets at homeeven starting fromwood chips.
Formaking pellets at homeit is also possible to perform a manual process starting with wood sawdust and a pressure roller; we are talking about a very long operation that has a low yield. It is unthinkable to consider powering a biomass stove withhandmade pellets!
