Recycled plastic in a hot glue gun

I searched for this on here, but only found it mentioned once.  Anyone have feedback on what plastics they have tried and to what results?   The mold would be easy, but I’m curious if anyone is getting good adhesion using the glue gun.  I’m still trying to get my machines built, so everything is theoretical right now for me.  Thanks!


might be possible with some fiddling (more heat & pressure). here a little bigger gun 🙂

there is a group of brazilian designers developing a plastic recycling gun:
