Chemicals group BASF said it would present new materials, concepts and recycling methods for polyurethanes at footwear technology exhibition Simac, which takes place in Milan from September 23-25.

It said the concept of meltable PU is “an essential step forward” in making footwear materials more sustainable. It said bottom units, upper parts or even complete shoes made of meltable PU or combinations of TPU and PU would work well in mechanical recycling operations.
