Dupe by Peter Trimble
Dupe, a mini manufacturing plant, converts urine, bacteria and sand into sandstone objects. The portable casting unit is made for pouring a urine and bacteria mix into a sand mould. A biological reaction of the urea and sand turns the form into sandstone and a solid piece of furniture.
Trimble’s research into the possibilities of microbial manufacture has led to a biomaterial that produces no greenhouse gases and can be reused as fertilizer. Potential applications include bricks for homes in developing countries and street furniture.
