Abstract
This work investigated biodegradability for the cellulose acetate, carbon dual, paper and web used to cigarette filter materials by soil test. Also, because of demanded a lot of the time and effort in case of soil test, the possibility of biodegradation by enzyme was studied. The evaluation of degradation for the filter materials by soil test was examined with the naked eye, electron microscopy and weight loss. The biodegradability according to the filter materials was represented in the order of paper > web > carbon dual > cellulose acetate without relating to the evaluation methods. Experiment of biodegradability by the cellulase(E C 3.2.1.4, Trichoderma viride) among the several biodegradability enzymes was demanded reaction time of the $5\~10$ hours and represented the same result with that of soil test.
