I had some interest in that topic a few months ago, but still have some rather general questions. The idea sounds great, but it is hard to tell how helpful it is for the environment without doing some sort of a life-cycle assessment of the entire process. Question such as how sustainable is it if we need three cactus leaf to make one sheet. Also, asking if someone might be able to answer or to point me where to read more. Is there a link between making plastic from plants and the plastic property of being non-toxic and/or biodegradable? Some plants are toxic, I would suppose this leads to toxic plastic. Same for biodegradability, how do we know the process of making plastic using plants (naturally biodegradable) plus other "things" leads to a plastic that is biodegradable?
