The history of the fuel obtained from wood processing waste. Have you ever wondered where the story of the pellet is born? This is how wood waste residues have become one of the fuels most used by households. The history of the pellets and its use in the field of alternative energy, are located between the '70s and early' 80s. The global energy crisis of the 70s, in fact, pushes technological research to look for new alternative sources.
The pellet thus changes its function. From the feed sector, its production evolves to be adapted to the renewable energy sector. In the early 80s, in the United States and Canada, the first industrial settlements were created for the production...

The wood pellet is a densified fuel deriving from an industrial process through which the raw material (mainly shavings and sawdust) is transformed into small cylinders with a diameter ranging from 6 to 8 mm and a length of 10-30 mm.
These transformations take place by drying and compressing the raw material. The binding capacity of the lignin, contained in the wood, allows to obtain a compact product without adding any glue, hydrocarbons and various aggregates.
In this way a high yield natural fuel is obtained.
The types of pellets on the market are many, with many features ...
The process concerning the production of pellets involves several phases of preparation of the raw material to allow the plant to work effectively.
The main operations aimed at obtaining the finished product are listed below:
A certified pellet responds to parameters dictated by the certifying body.
Certification standards change from country to country:
- Austria: Önorm M7135
- Germany: DIN 51731 and DIN Plus
- Great Britain: The British Biogen Code of Practice for Biofuel
- United States of America: Standard Regulations & Standards for pellet in the US (The PFI)
- Switzerland: SN 166000
- Sweden: SS 187120....
Nocciolino of pomace is a natural product, obtained only and exclusively with mechanical procedures during the processing of the olives.
During the extraction of extra virgin olive oil from olives, modern techniques have allowed to
enhance a further natural product, the peanut olive pomace, obtained thanks to specific machines (called pest separators) that exploit the centrifugal force alone.
In Italy there are about 80 pellet producers, of which over 70% are present in the regions of Northern Italy.
The companies of the Center and of the South Italy, although they are fewer than the companies present in the territory of Northern Italy, are widespread throughout the national territory.
However, several manufacturing companies from 2005 onwards have left the production activity to undertake the sale and marketing of the pellets after, according to the data collected, the market has recorded an unusual pattern.
Probably it is the most emblazoned in Italy, but not only.
Whether it is white or red fir, it makes no difference because they are comparable.
Not surprisingly, most of the fir pellets come from Austria and Germany, two nations that have great availability of fir woods.
The products certified EN Plus A1, are made with criteria, without additions or deficiencies, in compliance with the processes.
The most obvious advantage of pellets compared to wood is comfort.
The pellet is supplied in sealed 15 kg plastic bags, easy to transport, store and use.
The tank of most stoves allows from 50 to 80 hours of operation at minimum rpm, rarely
a stove must be loaded more than once a day, often a couple of charges per week are sufficient.
Pellet ash can be used as a fertilizer.
It contains potassium and phosphorus, two very useful substances to enrich the soil.
In addition, there is also a lot of calcium, which is necessary to reduce the acidity of the soil.
It also serves to drive away some parasites such as slugs, snails and slugs, since being a dusty substance, the ash sticks to the soft parts of their bodies, causing them to dry out.
The only disadvantage is to pay attention to the harmful substances present in the pellets such as glues, paints and solvents.
