Catalytic process converts mixed plastic waste into oil suitable for reuse
Researchers at the University of Amsterdam(UvA) have developed a new process for recycling mixed plastic waste into oil, via Solvothermal Liquefaction (STL). Developed within the European PLASTICE project under the leadership of Associate Professor Dr Shiju Raveendran at UvA’s Van ‘t Hoff Institute for Molecular Sciences, the Catalysis Engineering Group have designed a pilot plant to demonstrate recycling of mixed plastic waste using solvent, heat, catalysts and elevated pressure. This produces a dark brown oil that contains molecules that can be used to create new, virgin plastics and close the recycling loop on mixed plastics. The pilot plant will be tested in Spain, processing municipal plastic waste. Mixed plastic waste requires extensive sorting before recycling and a large proportion of materials end up in landfill or incinerators as a result. But the process of Solvothermal Liquefaction (STL) could help reduce the complexity and hurdles of this process, as STL can can break down multiple types of plastic simultaneously. The team will now scale up the experiment to industrial volumes Laboratory experiments found that after 30 …
