Sustainability of the wood supply chain
Nothing protects the land more than the woods. The focus on the sustainability of the wood supply chain is everyone’s responsibility: we deeply believe it since the worldwide woodland and forestry heritage is an integral part of our story.
The sustainable management of forests is vital as it allows to obtain the maximum quality of wood which, being a renewable resource, can be cultivated, processed, recycled and cultivated again, in an endless virtuous cycle that respects biodiversity, fertility, capacity of regeneration, the energy it releases and the extreme ductility of matter.


To protect and pass on to future generations this priceless heritage, is necessary to make business decisions that coexist with sustainable choices.
The selection of certified sources of supply is one of the keystones for a sustainable business. For these reasons, we select our suppliers on their environmental policies and to the PEFC ™ certificates that guarantee a sustainable supply chain.
