Could our overflowing landfills be converted into gold mines? Designer Inge Sluijs has found an way to turn landfill waste into “Plasma Rock” – an innovative material that can be used to create eco-friendly consumer goods. The durable rock is the result of plasma gasification – a process that heats landfill materials at extremely high temperatures. Although plasma gasification technology is not necessarily new, Sluijs’ process of using Plasma Rock to create usable products is unique.
