Where to Recycle Filament?

I have a huge bag of filament waste. Where should I send this? I know it is only commercially recyclable in like very specific cases so stuff like PLA will almost never be recycled. However, I do hear of companies accepting filament and they sell back the rolls and stuff. I'm not looking to make a profit or anything, just gotta get this off of me and I want the most sustainable way to do so.
