In today’s world of climate consciousness, more people are opting for renewable energy. Wood pellets are more friendly to the environment. More and more electricity generating stations are turning to biomass for electricity production. And wood pellets are becoming more popular in domestic heaters and stoves for cooking. 

The demand for wood pellets is increasing due to the rising concern about pollution and greenhouse gases.


Wood pellets do not contain any chemicals or binders, and this makes them safe for use in cooking appliances.

Wood pellets can be made from several raw materials including industrial waste (old packing crates), Sawdust (from furniture manufacture), Sawmill waste (from milling of timber), and other sources including the cutting down of plantation forests controlled by the FSC or similar bodies. Pellets derived from such sources will be accompanied by an FSC certification to show that the timber was sourced responsibly.

As they are made under very high pressure in a pellet mill. The wood is ground down to fine particles and forced through a die like a meat mincer. The high pressure causes the wood to produce lignin which is a polymer that will serve as a natural binder to turn the wood dust into a hard, high-density pellet.

It is important, when producing wood pellets, that all pellets are the same in every batch. To this end, a manufacturer will use a particular species of timber to feed into his mills.

The different species will determine calorific value, Sulphur content, ash content etc. We use a miller who uses Kaliandra for his stock. This gives a Kcal value similar to coal.

How Do Wood Pellets Compare

  • When used as heating, 1 ton of wood pellets equals:
  1. 450 litres of heating oil
  2. 643 liters of propane
  3. 453 cubic meters of natural gas
  4. 4775 KWh of electricity
  5. 1600 kg of log timber
  6. 500 Liters of diesel fuel
  7. 685 Liters of fuel oil

Materials Used in Pellets

Pellets are produced from several different resources. Pellets can be made from grass (used as a feedstock), wheat husk, rice husk, and other forms of biomass that do not contain lignin. The use of husk is very environmentally favourable as it makes use of what would be a waste product. Pellet producers generally use the same production methods worldwide.

Wood Pellets For Electricity Generation

Wood pellets/biomass is gaining popularity in developed countries as a fuel source for electricity generation. Biomass has an advantage over wind and solar as it can be used to generate electricity in any weather condition, day or night, windy or still. Much of the raw materials for pellet production can be derived from the thousands of trees that need to be felled to make way for the solar and wind farms and the roads leading to them.

Almost 16 million trees have been chopped down on publicly owned land in Scotland to make way for wind farms, an SNP minister had admitted amid a major drive to erect more turbines.19 July 2023.

So, these felled trees would be a great source of stock for pellet mills to produce wood pellets to save the environment by making way for wind turbines. 

The Rising Demand for Wood Pellets

  • The global wood pellet market is projected to grow from USD 10.52 billion in 2020 to USD 16.75 billion by 2027, with a CAGR of 7.28% during 2022-2027.
  • The market is primarily segmented by application (power generation and heating) and geography (North America, Europe, Asia-Pacific, South America, and the Middle East and Africa).
  • Europe is the largest market for wood pellets and is expected to maintain this position due to significant wood pellet production in 2021.

The world is witnessing a significant increase in the demand for wood pellets, a renewable energy source with remarkable potential due to the rise in demand for sustainable fuel across the world.

The popularity of wood pellets is increasing as they are being identified as an energy carrier.

There is a rise in the adoption of wood pellets in commercial and residential heating.

There is rapid growth in the installations of wood pellet power plants.

As there is a desire to replace fossil fuels for energy, wood pellets are filling this void.

Governments are incentivizing and supporting the move to sustainable energy.

Another factor is that wood pellets do not contain the levels of Sulphur and phosphorous that are present in coal. These elements cause corrosion and reduce the service life of boilers.

Wood Pellets Versus Coal

Wood pellets are a low-cost, low-carbon alternative to coal. Wood biomass is lower in nitrogen, Sulphur, chlorine, ash and other chemicals than coal and traditional fossil fuels.

As wood pellets are made from trees and trees are replanted, they are considered renewable.

When trees grow, they absorb CO2 and store it in the wood. When a tree is felled and burned, it can only emit the amount of carbon that it had stored in the first place. So, burning wood/biomass is effectively carbon neutral or zero Kg/MWh.

Scrap timber ready to be chipped.

Depending on the end use, some consumers of wood pellets are content with mixed pellet species. They simply want a combustible material to provide space heating.

When used in electricity generation, however, the quality must be consistent with the laboratory report on the sample provided. To this end, The pellet producer will always select a species of tree and not deviate from that species. In some cases, the pellet producer will also own the tree plantation. Once clear felled, he will cultivate the field and replant the next crop of trees. Hence making wood pellets a renewable energy source. 

Preparing the stock

Once the stock has been collected, the product is reduced by being fed through a woodchipper.

The chips are dried and then fed into the wood pellet mill via a conveyor system.

The mill will then grind the chips into dust under very high pressure and force the dust through a die very much like a meat grinder. The combination of friction and high pressure creates high heat which forces lignin out of the timber. This is a natural binder that holds the wood particles together to create a high-density pellet.

These pellets fall out of the die and into another conveyer where they are either bagged in jumbo bags or loaded in bulk into shipping containers.

The loading method is by the buyers’ demands.

The manufacturing process in summary

The process of making wood pellets involves several stages, from sourcing raw materials to the final pellet production. Here’s a general overview of the process:

Raw Material Selection: The first step is to select the appropriate stock for wood pellet production. Generally, clean, dry, and finely ground wood residues such as sawdust, wood shavings, wood chips, or even whole logs can be used. High-quality stock leads to better wood pellets.

Preparation and Drying: Before processing, the stock may go through a preparation stage, where contaminants like rocks, metal, or other impurities are removed. The raw materials are then dried to reduce their moisture content. Proper drying is crucial for achieving the desired pellet quality and efficiency during the palletisation process.

Size Reduction: The dried wood materials are typically further processed through a hammer mill or other equipment to achieve a consistent and fine particle size. This process ensures that the wood particles have a uniform size, which improves the efficiency of palletisation.

Palletisation: The processed wood particles are fed into a wood pellet mill, which is a machine that applies pressure and heat to compress the wood particles into small, cylindrical pellets. The mill’s die contains small holes through which the wood particles are forced, shaping them into pellets. The combination of heat and pressure helps bind the wood’s natural lignin, which acts as a natural binder, holding the pellet together.

Cooling: Once the pellets are formed, they come out of the pellet mill at a high temperature. They need to be cooled down to ensure their structural integrity and prevent damage during handling and packaging. Cooling can be achieved using coolers or ambient air in large cooling silos.

Screening and Grading: After cooling, the wood pellets may be screened to remove fines and broken pieces, ensuring only high-quality pellets proceed to the next stage. Proper screening also helps in achieving a uniform pellet size, which is essential for efficient combustion.

Optional Pellet Conditioning: In some cases, especially for certain industrial applications or specific wood pellet characteristics, pellet conditioning might be done. Conditioning involves adding moisture or other additives to the wood pellets to improve their durability or performance.

Packaging and Storage: The final step involves packaging the wood pellets into bags, containers, or bulk shipments for distribution and sale. Pellets are typically stored in dry, cool places to maintain their quality until they reach their end users.

It’s important to note that while this is a general outline of the wood pellet production process, variations and additional steps may exist based on the specific equipment, scale of production, and intended application of the wood pellets. Quality control and adherence to industry standards are crucial at each stage to produce consistent and high-quality wood pellets.

Each manufacturer has its characteristics, such as the quality of wood stock, production technology, and processing methods.
