Do cellulose based plastics pose any of the same hazards as petroleum based plastics?

If not, is the only reason for not switching to primarily cellulose plastic money?

Cellulose-based plastics were some of the first "plastics" discovered. Although there are constant innovations, the cellulose backbone just doesn't work in all the situations we need it to. That's why we made others. Further, many of them are not biodegradable and most require petrochemicals to make anyway.
