With my implementation team of ISO 9001 and 14001 we have a lot of discussions on operational control with life-cycle perspective. In the life-cycle perspective, we have things that we don't have control on, only influence (like material extraction or disposal of our products after our customers have used them.) How can we show our operational control when it isn't on under our control?
ISO 14001 states that you need to apply controls to the level possible so in case that you mentioned you can print instruction for the product disposal so your customers can dispose it properly. You can state users manual as an operational control for this life-cycle stage.
