What to do with used parts?
I'm building a small collection of old car parts that are really only good for scrap. Tensioners that stopped tensioning, sensors that stopped sensing, broken interior pieces… those sorts of things.
I usually throw them in with the cans and newspapers, and let the guys at the recycling center figure it out. The guys on the recycling truck usually accept that stuff (or maybe they just don't see it).
There are e-recyclers for e-waste; is there anything like this for car parts? The only other idea I had was smuggling parts into junkyards.
