Abstract

Chitosan has applications in
different industries, due to the superior properties, causing an increase in
the production of chitosan containing waste. Although composting is the most
suitable method for biodegradable wastes like chitosan, less is known about the
degradation of chitosan within the composting environment. In this study,
biodegradation behavior of bare chitosan films and neutralized chitosan films
were investigated under controlled composting environment according to
international standards. CO₂ emission data showed higher degradation
rate of bare chitosan films compared with neutralized chitosan films, which was
also supported by SEM images and digital photographs in addition to the TGA and
FTIR results. It can be concluded that the biodegradation rate of chitosan
films under the composting environment is highly related to the amount of
glycerol present in the films and the extraction rate of glycerol from film
structure.
