Wood pellets are manufactured by pressing wood sawdust where the own wood’s lignin, makes binder to form it, for this reason, it’s not required glue or any other substance more than the same wood. This process gives them a shiny appearance and makes them more dense than the original wood and turns it into a form of all-natural fuel.
The use of wood pellets as fuel, has several distinguishing advantages:
- Felling and pruning residues are used, so do not require indiscriminate felling of trees, which benefits the environment and our natural environment.
- CO2 emissions resulting from combustion are offset by those absorbed by the tree during its life cycle, and therefore does not increase the greenhouse effect, unlike fossil fuels.
- Its shape and high density (greater than wood) facilitates storage and transportation systems.
- Pellets have high durability, fully maintaining its quality if it keeps dry.
- They are clean and free of germs. They do not produce harmful fumes or gases for health which can be burned in densely populated areas.
To manufacture our pellets we use pine. Pine wood (coniferous) has a higher than other tree species heating value, mainly because of their higher lignin content and, in part, to higher resin content, waxes and oils of conifers.
Pine wood used is pine debarked, which we get the level of ash produced, after combustion, is less than that would be obtained with wood with bark or other types of agricultural biofuels.
