A scrap yard receives old household refrigerators and vending machines for crushing. Before the units are disposed of, who is responsible for ensuring the refrigerant is recovered?

For small appliances headed to disposal, the person who takes the final step in the disposal chain (such as a scrap recycler) must recover any remaining refrigerant or confirm through a signed statement that it was already properly recovered. Refrigerant may never be knowingly vented during disposal. This closes the loop so refrigerant is not released when appliances are crushed.
