Pellets & briquettes and others biofuels
Pellets and briquettes are standard formats recognized by international markets. These densified biomass formats meet technical criteria (length, width, diameter, etc.) so as to correspond to appropriate technologies for their use, especially in combustion via boilers.
Pellet
​
Pellets are cylindrical rods resulting from the compression of biomass waste, most often sawmill waste (especially sawdust and chips).
Resins contained naturally in wood are polymerized during compression and allows them to keep their shape. This format is widely used in Europe and is starting to develop in Morocco.
Briquette
​
A briquette is a format of a solid biofuel, marketed with others of the same weight and shape, obtained by die-casting of a previously ground natural resource.
If the shape is very small (2 cm in diameter), we are speaking about a pellet.
​
The manufacture of the briquette dates from 1833 and the first press. The model is perfected afterwards. The aim was to compress the coal dust so that it could be marketed more easily
Straw and ground biomass can also be compressed and converted into briquettes. this gives an economic value to green waste.
​
A first business plan has been prepared to finance this activity.
Wood chips
​
Shredded wood, also called "wood chips" is a fuel presented in the form of small pieces of homogeneous wood of approximately 3 x 3 x 0.5 cm. It is part of the firewood system for individuals, businesses and communities.
The biochar
​
Better known as charcoal, biochar is the result of a pyrolysis process, the heat treatment of wood in the absence of air.
The Green Goat team is preparing a project on this theme that will use not only wood but other biomass (non-woody), some of which are presented on the biomass inventory page.
Biochar has the advantage of delivering a higher heat output than the pellet or the briquette.
the second interest of biochar is its use as an organic fertilizer.
A specific development team is being formed.
