"I do believe that all manufacturers are obliged to take away all the packaging anyway."
Not sure I would agree with you there. I had this discussion, many moons back, with a private cardiology clinic who had just taken delivery of their new stress system. A very large crate (treadmill) and cardboard box (monitoring) where left over and they asked me to remove it. I politely declined, pointing out that, once you have finished your box of cornflakes, it is not up to the supermarket to take back and dispose of the box. You buy the device, you buy the box too.
Now, that being said, where I currently work we have a good recycling system set up out on the loading dock where all sorts of materials are sorted and packed up to be recycled. We, the biomeds, do our bit and when OEMs are doing install I am more than happy to point them in the direction of the correct disposal point. I have always found them happy to oblige.
