Abstract
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 cellulose ester product is combined with various additives such as acetins, agricultural fillers, and carbon particles.
