At the end of the commercial it states that the reason for this wood panel smartphone is to find ways to create a way to fund thinning of forests in human-made forests meant for harvesting/logging. Thinning is done to prevent overcrowding and to promote better health and growth rate of remaining trees.
I am guessing all the wood used in this commercial is from said thinning process. Such wood has limited use and demand due to its unreliable supply and lack of desired properties for industrial and household use (too thin, too soft, burns too quickly etc.). Basically it is repurposing of the harvested wood to give it more value in the long run. Kind of like making products like floor panels out of pine-beetle infested trees, I think.
