Amsterdam company Rutte Groep has succeeded in building a machine capable of recycling cement – a world first. The machine is called ‘Freement’, which is being presented today at the Provada fair in Amsterdam together with the New Horizon Urban Mining company.
Fremeent, invented by Koos Schenk, can separate blocks of cement into its three original materials of gravel, sand and cement. It is a big deal, considering that producing cement is responsible for nine percent of the world’s carbon dioxide emissions. Not unlike a cow, the machine ‘ruminates’ cement until the gravel is clean. Freement can process 130.000 tonnes of cement a year.
