Great points, now if we could only get everyone on the same page. There are still people out there that consider their own financial condition of higher priority then the life of the planet overall. Such short sighted priorities must be overcome for these initiatives to be successful.
Great list. I would add that when disposing of hardware, make sure that the company you are sending it to is disposing of it responsibly and not dumping the equipment in 3rd world countries where men, women and children are dismantling the equipment and being exposed to life threatening diseases from the waste products.
I agree that disposal is also an important consideration. Progressive companies today are taking the time to determine what of their old hardware can be refurbished, resold, or transformed into a commodity (ie some computer casings are being melted down and reused as Trex decking). Taking the time to do this can actually mean some profit, too, from the sale of the above. Perhaps not enough to offset the time and energy it takes to determine what to do with old hardware in the beginning, but over time it might even out.
I would think there has to be good money in the recycling of these products as there are s number of metals which are used in their manufacture. There will however always be those looking for an additional .02 on their transaction and willing to screw someone else for it.
