EcoARK, a three-storey exhibition hall made from 1.5 million plastic bottles, has been unveiled in Taiwan in a bid to raise interest in recycling.
The NT$133m (US$4.15m) pavilion was created by Taiwan-based company Far Eastern Group and is touted to be the first of its kind in the world.
Miniwiz Sustainable Energy Development served as contractor for the project, which used bottles from Taiwan's waste stream.
The bottles were then reprocessed into plastic containers that are interlocked to block the elements and withstand storms or earthquakes.
The pavilion includes an amphitheatre, museum space and a screen to collect rain water for air conditioning, while clear plastic containers allow natural light into the interior.
The 130m-long, 26m-tall structure was commissioned three years ago. It will be donated to the government next month to be used as a fashion pavilion for a flora exhibition.
After the show, the wall panels will be packed up and reassembled elsewhere, according to Reuters.
