I don't know what your laws are like in the USA but here in the UK all refrigeration waste has to be dealt with by a special contractor and hence there are large dumps where the refrigerators are moved to and held pending collection by the contractor. Your local municipality should be able to tell you where to find this kind of hazardous waste dump. Of interest they had a program on TV showing them moving these old fridges to Eastern Europe and Africa for re-use.
The old refrigerators are more efficient because most of them used R12.
