The Japan Pavilion to be built for Expo 2000 in Hanover, Germany, will be one of the world's largest structures made out of paper, according to the Japan External Trade Organization.
The pavilion, which will be constructed mostly of paper, will measure 72 meters by 35 meters and stand 15.5 meters high. JETRO, which is in charge of designing, building and operating the pavilion, will use paper tubes 20 meters long and weighing 100 kg each in the structure.
When the exhibition ends, the tubes will be reused to demonstrate the feasibility of environmentally friendly construction techniques, the government-affiliated body said.
The pavilion will be used to present Japanese technologies that can reduce carbon dioxide levels, such as clean energy sources and environmentally friendly transportation systems.
JETRO will be participating with the Transport, International Trade and Industry, and Posts and Telecommunications ministries in the exposition, which is to be held from June 1 to Oct. 31.
A total of 192 countries and regions will participate in the expo, which is expected to draw around 40 million visitors.
