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. The rock is quite durable and completely non-toxic – and Sluijs imagines that a worldwide circular economy could turn landfill junk into environmentally-friendly consumer goods. According to the designer, 20 kg of Plasma Rock can be created out of 100 kg of landfill waste.
Sluijs has focused her efforts on coastal landfill sites, starting at the East Tilbury landfill located in Essex, England. Scientists consider coastal landfills to be ticking time bombs, considering that the land is being quickly eroded by rising sea levels. Transforming waste into Plasma Rock would reduce landfill volume while diverting dangerous materials that would otherwise pollute the water.
Plasma Rock starts as a powder, which can be formed and sculpted into different objects. Sluijs recently used the material to create Tilbury Tiles, which are distinctively decorated and marketed as souvenirs from the East Tilbury area. She has also developed glass vases decorated with specks of the rock. Through her designs, Luijs hopes to demonstrate not only the potential of Plasma Rock, but also the possibility of using landfill waste to the benefit of the environment.
