Researchers at the University of Ghent looked at advanced recycling as a means to gain high-quality petrochemical feedstock of mixed plastic waste streams.
Even though advanced plastic waste recycling via pyrolysis and subsequent steam cracking of pyrolysis oils has the potential to partly close the cycle between the petrochemical production of plastics and current end-of-life waste management, they write, the greatest obstacle for chemical recycling is the high contamination of plastic waste.. Of course the complex composition of real plastic waste often also hinders good results.
