Abstract: Activated sludge has been used to study the degradability law of ramie sticks fiber tableware in order to learn the degradability of it, contributing to provide basis of large-scale production of the ramie sticks fiber tableware. The author used biodegradation rate to evaluate the degradation ability of polypropylene, filter paper, ramie sticks fiber tableware, pulp molding tableware and corn plastic tableware in activated sludge. The results showed that: during the testing time (28 days), the filter paper had the highest degradation, pulp molding tableware came second, the plant fiber was more stable than paper, its biodegradation rate was 60.59%; polypropylene and corn plastic tableware degrade little in the activated sludge system. Increasing the surface of ramie sticks fiber tableware and the ratio of activated sludge to ramie sticks fiber tableware could improve the degradation degree of ramie sticks fiber tableware.
