VTT says it has developed a novel extruder for processing problematic waste




HELSINKI, February 7, 2019-

VTT’s cylindrical extruder promises to revolutionise the processing of recyclable materials and thereby promote circular economy business. The extruder can be used, for example, to turn problematic textiles and plastics as well as food waste into pellets. The first prototype has already exceeded the industrial steering group’s expectations during initial testing. VTT is currently looking for a partner to commercialise the technology.

VTT’s research scientists have been testing the prototype’s performance with, for example, pieces of plastic film, mixed plastic waste, various kinds of textiles and bread. In addition to recycling, the device has been used to produce long fibre composites, and it can also be utilised in food and feed processing.
