So they will go through your regular garbage? Rip open the bag and dig through it?
I know people, who uh, put gallons of oil into their garbage along with oil filters 3x bagged. No one cares.
Going to the parts store to recycle it is messy, annoying, and a 50% chance they won't take it.
My MIL once had her recycling not picked up because there was a pizza box that had some cheese on it. She cleans out the metal cans and plastic bottles. I told her she's wasting time doing the recyclers work, using fossil fuel to heat up the water so some 3rd grade dropout doesn't get mad. When I do her garbage it all goes in a bag, who cares.
GreenPeace claims plastic recycling is a scam anyway:
