“There is a huge need for construction materials, at the same time the planet everywhere is littered by millions of used car tires. A way has to be found for re-using the materials that car tires are made of: rubber and steel. Large scale processes for this are well known. At the smallest scale of use better methods of recuperation have to be developed.”

“Each car tire contains 70 meters of steel wire with a 1 mm cross section. When the properties of the composing parts of a used rubber tire are well understood, then the practice of recuperation can be adapted to it.” Illustrated manual at Demotech.
