The most ecological raw material:

The wood is practically the only renewable raw material that is in use to great scale and its use does not damage to the environment.

The natural resources are started to be seeing as a good that has to be administered wisely, since it has to be the inheritance for the future generations. The factors that contemplates the "supported development" might be summarized in:

Energetic saving: the energy necessary for the manufacture of the wood is null. The tree uses solar power for its development (chlorophyllic function). And the consumption of energy in the process of transformation of the wood is very small (430Kwh for ton) in comparison with those of the steel (2700 Kwh for ton), aluminium (17000 Kwh for ton) or cement.

Respect to the environment: The orderly exploitation of the forests brings together the productive aspect (getting the wood) with the respect to the environment and the conservation of the ecological balance. There have joined sophisticated controls to the manufacturing processes that allow to avoid the deterioration of the environment.

Recycling and saving raw material: Once finished its cycle of life, the wood retrains or is revalued as fertilizer or calorific energy, without contaminating to the environment. If the costs of recycling or elimination of residues were included in the price of the industrial products, very few materials might compete with the wood.

Its technology has been evolving. There have been improved the properties of its derivative products, there have arisen new products that have extended its field of application and have complemented with other prime matters to improve its performances.
