The Wood Pellet

In a lot of European countries, wood pellet is made from the compression of sawdust. It is a popular energy because on one hand it is using the already existing wood residuals, and on the other hand, it is a renewable energy which creates employment.

The pellet can be used by private individuals, but also for the industry or for collective heating systems. The wood pellet market is dramatically increasing in France but is already very developed in the other European countries.

A clean and renewable energy

Like every wood energy, the combustion of pellet does not increase the quantity of CO2 already existing in the atmosphere.

Indeed, if you look at the wood’s growth cycle, you can see that the CO2 arises from the combustion is the CO2 that the wood has collected during its growth.

Cycle naturel du bois Ligérienne

To produce wood pellet, we only use the residuals from the wood industry, we do not cut trees to make sawdust, and we only use what is currently available in the market.

Moreover the sawdust we use is coming from our area in order to reduce as much as possible the transport and the impact of our activity on the environment.

Alongside a correctly managed forest, wood pellet is certainly the best renewable energy.

Wood Pellet and its competitors

When we talk about energy, it is important to compare both its impact on the environment, and its cost for the final user.

Energies and global warming

This table shows the impact of different energy on the environment (source: AGEDEN).

Family Energétique Type CO2 (tons/year)2 (tonne/an)

Renewable energies

Wood pellet 0
Crusher wood 0
Wood log 0
Solar 0

Fossil energies

Fuel 7,4
Natural gas 5,2
Propane gas 6,3

Electrical energies

Electric 5,2
Geothermic 2,1
Exothermic 3,1

We can add than a car rejects about 3 tons of CO2 a year (for 20, 000 km).

Concerning the electrical energies, in winter most of it is produced by fossil energies and the nuclear electrical plants also produce dangerous hazards that we can’t treat nowadays.

Energies calorific power

In the table below the PCI of different energies.

Energy PCI Density Humidity
Fuel 10 kwh / litre 845 kg / m3 /
Natural gas 10 kwh / m3 0,74 kg / m3 /
Propane gas 2,8 kwh / kg 2,04 kg / m3 /
Corn and cereals 4,2 kwh / kg 750 kg / m3 <15%
Wood log 3,5 kwh / kg 420 kg / m3 <25%
Bois Plaquette 3,5 kwh / kg 260 kg / m3 <25%
Wood pellet 4,9 kwh / kg 650 kg / m3 <10%

1 ton of wood pellet equals 500 litre of Fuel.

Price of the energies

The table below, presents the current prices of the energies in France (source ITEBE).

Chauffage domestique - comparatif du prix des énergies

This shows than loose pellet is one of the cheapest energy. We can also see that pellet in bags has broadly the same price than the fuel but with a much lower environmental effect. The same can be said about the gas.
