The guitar tested in this video is the electric model Ethiq range presented in Berlin during the 2nd edition of the Holy Grail Guitar Show by luthier Jean-Yves Alquier. The characteristic of this range is that it is made of bamboo from 65% to 100% as in the case of the guitar tested in this video. So this might be one of the first sustainable guitar from a luthier.

We clearly see in the photo below how the body of the guitar is composed.
