What is an Earthbench? (click to enlarge)
An Earthbench is made out of trash and earth.
The Trash = Bottle Bricks, or Portable Landfill Devices, are plastic soda bottles stuffed with soft inorganic landfill trash till they become compressed like bricks. The Earth = cob is a mixture of clay, sand, straw, and water. It is a natural cement that - when protected - will stand the test of time. If a natural builder is unavailable to assist in a project, then regular cement mortar is recommended instead. Learn more in our Earthbench 101 How-To's! |
