Abstract

See full text

The invention relates to a biodegradable plastic having increased biodegradation speed. Said plastic comprises a) finely distributed particle of a biodegradable, water-soluble, organic component, and b) finely distributed particles of a water-soluble, inorganic component promoting the growth of microorganisms and comprising N, P, and/or S. Said plastic is particularly based on cellulose esters such as cellulose acetate. Preferable components A are water-soluble saccharides and/or water-soluble organic acids. Said particularly advantageous biodegradable plastic is particularly available in the form of fibers, films, injection molded items, granulate beads, and containers. Controlled-release biocides and/or fertilizers can also be included in the molded part, wherein the molded part is degraded faster in the environment as said ingredients are released. The accelerated biodegradation is based on a synergistic interaction of the components indicated.
