I also assumed that was the process here, but from the article this does seem to be something slightly different. Overall process seems to be roughly the same, but they're using biodegradable materials instead of resin, apparently a mix of egg white and "rice extract"

Now I'm personally skeptical about how long-lasting something made from egg and rice can be, although I guess there are still tempera paintings (tempera paint is made from egg yolks) around from the Renaissance, so what the hell do I know?

And the chemicals used to strip the lignin from the wood aren't exactly the most environmentally friendly, but I guess arguably they're better than some of the ones used in plastic production.
