In the blown bottle the sides are physically altered, their tensile strength increases a lot, and is surprisingly in the same ballpark as structural metals.
So I plan to restart PET processing melting experimentation once I motorise the mini shreader ( previously I hand operated it in a fitness workout).

I have done a lot of research and have tried to make filament out of plastic bottles. Our plastic bottle in Australia are HDPE PET 2. I ground the plastic down to small particles. I then dehydrated it. then I fed it into the Filastruder at 210 Celsius. All that happened was it clogged up in the end of the auger and did not extrude out the end.

Does anyone have any advise for me

Thanks
Bec
