While the entire styrenics value chain has joined together to deliver on the intrinsic circularity of styrene, it might be said that it is the converters who are on the front line.
At Styrenics Circular Solutions, we know our converter members have a direct relationship with the brand owners and retailers and that they share their desire for the development of sustainable packaging for end consumers that retains all the excellent properties that polystyrene has to offer.
Recently, several converters had the opportunity to test food contact mechanically recycled polystyrene in their existing facilities - with overwhelmingly positive results.
Having been able to show that rPS truly offers a drop-in solution is hugely important for converters and brand owners: it means there is no need to purchase new equipment or make any adjustment to their existing extrusion or Form Fill Seal.
Moreover, the fact that the final application - in this case, yoghurt multipacks made from rPS - display the same performance as pots made from virgin material is crucial to brand owners and retailers alike.
The key test results shared by COEXPAN and Intraplás when they compared the behaviour of mechanically recycled polystyrene with virgin polystyrene in their existing facilities, showed that recycled polystyrene behaves exactly as virgin material. No adjustments were required in their equipment and the machines demonstrated the same productivity. Multipack yoghurt pots were produced using the existing form and fill and seal (FFS) machines, with both companies reporting that recycled polystyrene produced impeccable pots, with equipment running as normal, the same heating requirements, the same cutting tools and no change in productivity.
