Abstract
A biodegradable drinking straw is made of plant fiber powder and at least one polymer. The at least one polymer is polylactide (PLA), polybutylene succinate (PBS), or polypropylene (PP). As an alternative of drinking straws made of traditional plastic materials, the biodegradable drinking straw when buried in landfills can be degraded by microorganisms and decay, eventually becoming a part of the nature again. Besides, the biodegradable drinking straw is made of neither non-petrochemical materials nor silica, so its production avoids excessively consuming the finite resources, thereby being contributive to energy conservation and environmental protection.
