TwoBears' BioFila Silk and Linen 3D Printer Filament

Looks like yet another bio-degradable 3D printer filament has made it to market. Twobears has announce 2 new filaments, which are completely bio-degradable. They are Biofila Silk, and Biofila Linen

Both new filaments will go on sale starting next month, and have an added hardness, above and beyond what most PLA filaments offer. here is a picture of a 3D printed Butterfly using the Biofila Silk filament:

This is all nice and all, but I don't know if people are really going to end up going out of their way to get bio degradable filament. In a perfect world they would, but I just don't see all that much interest in this kind of thing.
