I buy shredded waste plastic.

Which means = they take car dashboard, wash it with water/solvent then shred it into very tiny pieces.

I take it and dry it in oven then I put that in an airtight jar, and let it cool to room temperature over next 24 hours.

I mix it with some virgin plastic (also dried and stored in airtight container)

Then I pour the plastic into hopper and extrude it into filament.

This filament is made from recycled blue ABS: https://youtu.be/Xirli3qDJlU
