*  TeTRA CUP is a portable and reusable coffee cup designed to encourage recycling.  

*  The biggest advantage of TeTRA CUP is its compactness.  It can be folded completely flat after use,  making it convenient to carry around.

*  This presentation proposes a TeTRA CUP recycling system in which coffee drinkers deposit the used TeTRA CUPs to a nearby collection box set at coffee shops.

*  The portability of the TeTRA CUP is expected to facilitate the collection of the used TeTRA CUPs.

Thank you
