General information

What are wood pellets?

Wood pellet is a fuel made of pressed wood sawdust, often recovered from carpentry processing scraps. The material used cannot contain
any extraneous substance such as, for example, glue, lacquer or synthetic substances.
The sawdust, once it has been dried and cleaned from impurities, is pressed using a die with holes: as a result of high pressure, the
sawdust heats up by activating the natural wood binders; this way the pellet maintains its shape even without adding artificial substances.
Wood pellet density varies based on the type of wood and can exceed that of natural wood by 1.5 - 2 times.
The cylinders have a diameter of 6 mm and a variable length between 10 and 40 mm.
Their density is equal to approximately 650 kg/m3. Due to their low water content (< 10%) they have a high energy content.
The UNI EN ISO 17225-2:2014 standard (EN PLUS) defines pellet quality by specifying three classes: A1, A2 and B.
Pellets must be transported and stored in a dry area. Upon contact with humidity they swell and become unusable: it is therefore necessary
to protect them from humidity, both during transport and during storage.
Keep fuels and other flammable materials at a suitable distance.
Elledi recommends using wood pellets classified A1 and A2 according to the EN ISO 17225-2:2014 (EN PLUS) standard, or
certified DIN PLUS (more restrictive than the A1 class) or ONORM M 7135.
Pellet may be light or dark coloured, it is normally bagged into bags that show the name of the producer, the main characteristics and
classification according to standards.
