The Extruder

This is the beginning of the extruder assembly. 
Shredded plastic flakes go in the hopper...

...heat up in a tube that has heating elements strategically placed (the goat is just observing)... an auger bit turns and pushes the melted plastic out of the end of the tube. 
It comes out like toothpaste.

This model is still in the testing phase. We shredded #2 HDPE plastic (laundry detergent bottles and milk cartons) and tried the extruder with the flakes.
The result was gray plastic in the shape of a poop emoji.
Get it? #2 and #2...ahhh the plastics humor...
