Alternative to wood on solid body

[Fernando Esteves]

Hello!
I'm from Brazil and here the deforestation of all kind of forests, swamps and whatever else can be transformed into cropland to make soy for the cows food grows every year.

So, I'm starting to become sensitive about use only wood as materials to build guitars, specially because there are some new companies creating new kind of materials to guitar, like Aristides.

I got interested in learn a bit about it, but couldn't find anything and I'm not sure Aristides will tell me anything about their process, it seems like was years of research for them.

Does anybody has any familiarity with that?
Thanks
