There is. A quick Google search found several companies near me who will by scrap metal off of me.
The problem is that a pound of aluminum goes for about $0.45.
That does not come close for paying for a weekly curbside pickup service, which is what most individuals use for recycling.
Heck, they probably wouldn't even take an unsorted collection of "recyclables". The company I am looking at drops the price for unspecified "dirty" aluminum to $0.25 per pound.
