Smart Crusher

Smart Crusher B.V. owns a CO2-free technology, and has developed a machine, that allows to free the gravel, sand, used- and non-activated-cement from concrete waste. In concrete about 50% of the cement did not react with water, so still could be reused. When producing 1 kg of (Portland) cement, 1 kg CO2 is emitted, so using the non-activated cement will offer a tremendous saving in CO2 emission.
Next to that Smart Crusher B.V. is developing a technology to upgrade the used-cement to a new binder, using electrical energy.
