Rengo Provides Tube Board to Dome C of BLUE OCEAN DOME

2023.08.31

Rengo provides the tube board used in Dome C of BLUE OCEAN DOME, a pavilion by the specified nonprofit corporation ZERI JAPAN. Based on the theme "Revitalization of the Ocean," BLUE OCEAN DOME will have displays encouraging changes in behavior toward the earth and oceans. The pavilion comprises three domes—A, B, and C—with bamboo, carbon fiber, and tube board used as the structural materials respectively for each dome.

Each year, Rengo manufactures approximately 76,000 tons (for FY2022) of tube board. The tube board provided to Dome C is a special reinforced tube board with high strength. Similar to corrugated board, this tube board is mainly made from waste paper, but has been made lighter while keeping higher strength using Rengo's unique technology. After the Expo, the plan is to collect the tube board to use as raw material for paperboard.
