I mean, I’ve worked at a number of hospitals in the US and never seen a recycling receptacle for our waste. Our waste either goes in a biohazard bag to be incinerated, sharps containers to be disposed of (altho not sure in what way), or a regular trash can to presumably in a landfill.

Not sure if other countries are different, but I can’t imagine they sort through our biohazard waste bags for plastic materials.
