Biodegradable starch acetate plastics are synthesized from whole agricultural flours and acetylating agents, without the use of solvents. The process includes a low temperature, staged addition of catalyst to the reactant mixture. The resultant polymers may be blended with other polymers, and biodeg ...

Glenn R Elion: Synthesis of plastics from recycled paper and sugar cane. International Communications & Energy, Townsend and Townsend Khourie and Crew, September 14, 1993: US05244945 (12 worldwide citation)

A method is provided for preparing a cellulose ester plastic composition from waste paper (e.g. recycled paper) and/or sugar cane bagasse. The paper or bagasse is reacted with an acid anhydride in the presence of a catalyst to esterify some of the hydroxy groups on the cellulose. The resulting cellu ...
