It stated as "Rubbish bin inspires Tawain's plastic bottle building." A building that will be used for exhibits and fashion shows has been out of 1.5 million plastic bottles.  This is the first fully functional plastic building. 

The bottles are changed into interlocking shapes that seals the builiding. The bottles can be filled with air to deflect heat and keep the building cool or it can be filled with water or sand to absord heat and keep the building warm.  The translucent material baths the building with natural sunlight during the day.
