Study on the Performance and Biodegradability of Three Kinds of Biodegradable Dishware

Abstract:

The performance and biodegradability of plant fibre and starch dishware (PFSD), pulp model dishware (PMD) and starch plastic dishware (SPD) were studied. The experimental results showed that these three kinds of dishware satisfy the requirements of use. The fungi growth degree and the weight loss percentage of these materials were analyzed. The experimental results showed that the growth grade of PFSD and PMD were both Ⅴgrade and the weight loss rate respectively were 41.59% and 82.73%, the biodegradability of SPD was not obviously observed in the whole process of the experiment. The degradation speed was analyzed, which showed that the degradation speed of PFSD and PMD was faster in the former two weeks than that in the latter two weeks. The biodegradability of each kind of dishware were compared under three different environments, the results showed that inoculation environment (T=30°C, RH>90%, 28 days) is the best environment for dishware to biodegrade by fungi.
