Engineers have modelled a new way to recycle polystyrene that could become the first viable way of making the material reusable. The team of chemical engineers, based at the University of Bath in ...

Guoliang Liu at Virginia Tech and his colleagues have developed a method to break down polystyrene and convert it into a chemical that is far more valuable. The process is energy efficient and ...

Previously, polystyrene was the largest stable synthetic molecule, at 40 million hydrogen masses. To create their molecular giant, Schlüter and his colleagues started with standard polymerisation ...

(Willy Kurniawan/Reuters) That's the difference with Pyrowave's technology — it uses a "chemical recycling" process to take waste polystyrene and generate brand-new styrofoam. Microwaves heat ...

Chemical recycling might offer help. Depolymerization can break down polyester and polystyrene into their raw materials for conversion back into new polymers. And pyrolysis can turn mixed plastic ...

This is far bigger than the previous record-holder, polystyrene polymers that were only 40 million hydrogen atoms. Still, it’s only a fraction of the molecular weight of DNA. New Scientist ...
