Greenbrier East High School InvenTeam
The Greenbrier East High School InvenTeam invented the Greenbrick™ to reduce the volume of waste cardboard in landfills by producing a building material from the waste. The pressed cardboard Greenbrick is fire retardant, water proof, and cost efficient. The Greenbrick takes approximately two minutes per brick to mold using a human-powered press and dries in 24 hours. Each brick consists of approximately 335 kg of shredded corrugated cardboard. Greenbrick can be used to replace standard bricks or deployed as a system to create temporary buildings after a natural disaster.
