Zusammenfassung:	A process for recycling waste from the manufacture of filtered cigarettes is disclosed herein. The process comprises the following steps: A waste stream from the manufacture of filtered cigarettes is provided. The waste stream includes tobacco, filter tips comprising cellulose ester polymer, and paper. A substantial portion of the filter tips is separated from this waste stream. The filter tips are washed with a sufficient volume of water to liberate bound tipping paper and to remove contaminants from the cellulose ester polymer. The cellulose ester polymer may then be dried, resolutioned, and processed into useful articles of commerce.
