ACTION PLAN - Don't recycle! It's better to re-manufacture existing cartridges than to waste energy turning them into something else. The original manufacturers may not be keen on the process, but when a cartridge can be reused three to seven times with no discernible reduction in quality, it makes both eco and economic sense. Plenty of vendors offer re-manufactured cartridges. The alternative - binning them once they're done - is rather like replacing your chicken every time it lays an egg.
GREENIE POINTS - Two - it'll be better for your budget, as well as for the soil.
