On investment into recycling, absolutely: the ability to sort based on densities and different polymer types. You're able to sort them even through a regrind process, which separates them based on different burn rates. When they're extruded out of an extrusion machine, you're able to burn off some of the contaminants or labels.
There are options out there, but we've gone to using virgin plastic all the time, as opposed to recycling and using the regrind mixes.
