Bio-Degradable USB stick

Bio-Degradable USB stick

Hong Kong-based Hoshino, released of what it's designated "the world's first bio-degradable USB disk."
The key is also shaped like an ear of corn, so you can acknowledge your own greenness, every time you go to retrieve information.

It is made of polylactide(PLA). PLA uses annually renewable plant resources (corn) as raw material, which is fermented and distillated to produce lactic acid.
Followed by the process of dehydration polymerization, high-temp depolymerization, refining and finally polymerization, lactic acid is then transformed to PLA. Its products can be degraded to carbon dioxide and water by microorganisms in the soil after use and do no harm to the environment.
