Novel recycling method for PP/MMT nanocomposites by pyrolysis was elaborated.
PP/OMMT nanocomposites were prepared by melt intercalation.
The pyrolysis process was carried out at 600 °C.
XRD patterns confirm that crystalline structure of pyrolysed MMT was basically kept.
Composites with pyrolysed MMT exhibit mechanical properties similar to those with pristine MMT.
