Pellets are small compact cylinders made of biodegradable material, mostly consisting of pressed sawdust. These cylinders have a homogeneous appearance and their dimensions are standardized to optimize combustion. The root of this lies in need. Making use of wood waste produced in the wood industrysuch as sawmills and carpentry workshops. A resource from these wastes clean and renewable energy It has gained popularity in recent years due to its efficiency and low environmental impact.
How are pellets made?
The pellet production process begins with collecting the base material, which is mostly sawdust, but other organic materials such as hazelnut shells or agricultural residues can also be used. After the material is collected, it is dried. To ensure good combustion, it is important that the moisture content of the sawdust is very low. Generally, The ideal moisture content is between 8% and 10%.
After the material dries, it is subjected to crushing and grinding until a fine powder is obtained. This powder is then sent to the pelletizing machine. In this machine, sawdust is exposed to high pressure and temperature, which causes the release of lignin, which is a natural component of wood and acts as a binder. This lignin allows the sawdust to adhere and form the small cylinders characteristic of pellets.
Once formed, the pellets are cooled to stabilize their shape and then sieved to separate those that do not meet the standard size. Finally they are ready to be packaged and distributed.
Marketing of pellets in bags and pallets
The marketing of pellets is adapted to the needs of consumers and distribution logistics. They are usually sold in plastic or paper bags. 15 and 20 kilograms of product. These bags make it easier to carry and store, and also protect from moisture.
For consumers requiring large quantities such as industries or large heaters, pellets are offered on pallets. A typical pallet can contain 65 to 70 bags, or about one ton of pellets. This presentation enables easy transportation with forklifts and reduces transportation costs per ton.
15-pound bag of pellets at Leroy Merlín
The cheapest pellet bag that Leroy Merlín sells is from the Iberpellet brand. It is indicated for pellet stoves and boilers and has a moisture content of 7% and ash production of 0.6%. The price of the bag is 5.49 euros, so the weight goes to you 0.37 euros.
For the same price, you can also buy a Wood Pellets brand bag, made of pine wood, with a moisture content of 8% and ash production of 0.4%.
Lastly, and slightly more expensive, you have the Bioforestal brand bag. 5.75 euros (0.38 euros per kilo). Humidity rate is 4.6% and ash production is 0.55%.
In summary, pellets have established themselves as a sustainable and efficient energy option. Waste from the wood industry is used in the production process, and its marketing has been adapted to satisfy both small consumers and large industries. The increasing demand for clean and renewable energy will certainly ensure that pellets remain the preferred energy solution well into the future.
