I agree on the risk aspect and that was the driving force. I had more examples I got from the exec's like "What if one of these old servers burn a house down? Who you think they are going to sue".
Also on the recycling side that there are checks in place that if say my company says "no" to refurb that they shred the servers up and recycle the bits they can.
But something has to give, over my career I have seen so much just be carted off to the landfill it would make you sick. And I worked small data centers. Nothing like what they are proposing now.
