Biodegradable USB drives, also known as eco-friendly USB flash drive, are storage devices with casings made from materials like wheat straw, corn stalks, or plant stems. After use and disposal, these casings naturally decompose to reduce environmental pollution.
Key feature：casing materials that can be broken down by microorganisms under specific conditions, while the internal electronic components retain the storage functionality of traditional USB drives.
Biodegradable casing materials:
Bio-based plastics: Such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), produced from plant starch or microbial fermentation. These decompose into carbon dioxide and water when exposed to soil microorganisms.
Natural fibers: Eco-friendly paper, wheat straw, or bamboo fibers, shaped through physical processing. These materials naturally decompose after disposal.
