Wood, eco-friendly or not?

The debate often comes up when it comes to wood energy: is it really an economical solution or, on the contrary, devastating for the environment? In order to provide you with clear answers on this subject, discover the main arguments in favor of this resource, as well as those against it.

Wood, an ecological resource…

There are many reasons why wood energy is an ecological resource. Here are the main arguments that support this assertion.

A neutral carbon footprint

A tree naturally carries out the phenomenon of photosynthesis. It absorbs carbon dioxide from the air and releases oxygen. This quantity absorbed is equivalent to that released at the time of its combustion, when it is transformed into firewood. This is why its carbon footprint is considered neutral.

A renewable resource

The forest renews itself quickly. Awareness campaigns encourage citizens to carry out reforestation in order to preserve forests, especially where a large number of trees are felled for use as firewood. It is the resource that renews the fastest. Indeed, it takes, at most, 200 years for a forest to renew itself, while coal can take up to 300 million years and oil can take up to 450 million years.

Very little waste

Wood is one of the materials that most respects the zero waste policy. Indeed, thanks to the different forms of energy wood, each part of the tree can be used as fuel. Solid wood is used as logs, while shavings, scraps and dried foliage are compressed and made into pellets.

…but with a few things to consider

However, you must take these few points into account if you want to guarantee that the wood is truly ecological.

Choosing the type of wood to use as fuel

Not all trees are suitable for use as firewood. Indeed, resinous species tend to produce more residue during combustion. On the other hand, hardwood species such as oak, beech or hornbeam are more suitable. A large quantity of residue would go against the ecological aspect of the wood.

A level of drying to respect

In order to be an effective fuel, wood must dry properly, with minimal humidity. If this rate exceeds 20% when the wood is used, harmful particles will be released into the air. In this case, the wood will no longer be considered ecological.

An operation to master

Finally, you need to know how to control logging and avoid intensive cutting. Trees play an important role in the climate of a region, as well as in the preservation of the quality of the soil, local fauna and flora. Excessive exploitation of a forest accelerates environmental degradation. The precise criteria on the number of trees to be felled per year, the age and size of the trees to be felled, as well as the frequency of reforestation in the region must be respected to ensure the renewal of the forest.

Conclusion

Ultimately, wood is an ecological resource and could represent the future of renewable energies. However, measures must be respected to preserve this balance and this could represent the greatest challenge for humans.
