Having gone through this exact situation with corporate attorneys before, I can tell you there is more than one contract in force here. Believe it or not, if you tell customers you will recycle old products for them, you'd better not sell them instead.
When you told them you would recycle the old products, you actually made a contract with them. Don't call it recycling if there is any chance at all that you may instead resell. We learned that the hard way.
