To investigate the effect of lignin content on the material prepared from thermoplastic starch and sugarcane pith (TPS/BP), individual alkaline and combined acid and alkaline pretreatments were employed to obtain BP with different contents of lignin for preparation of TPS/BP. Degradation by microbial organisms using shaking flask and observation of morphology by using SEM were investigated. The deepen scratch-like structure on the surface of BP was observed, which is possibly due to the removal of lignin. Lignin content was decreased by 15% after pretreatment at 100 °C using 5% NaOH solution. The biodegradability of the resultant TPS/BP was improved by 61.76% after 10 days’ digestion at 30 °C with a rotatory speed of 150 rpm. The biodegradability of TPS/BP with lower lignin content of 4–5% was significantly enhanced, with complete degradation after 10 days’ digestion in shaking flask.
