Transparent Wood? As a biodegradable material for phones and such

From an article in Phys dot org, see link below. Some researchers are developing transparent wood products, and from non wood sources. By removing liginds and starch perhaps.

That leaves a transparent product that is also biodegradable as a potential replacement for some plastic products like a cell phone case perhaps

They are also looking in to ways to add conductors and materials to make them support some electrical functions
