"A comparison of costs for new and refurbished machines indicates that material input costs per product could be reduced by up to 60%, net. From an industry perspective, a transition scenario in which the collection rate increases from 40% to 65% due to adoption of new leasing models, and 50% of collected machines get refurbished (and the other half gets recycled) would generate net material cost savings of more than 12% of total industry input costs."
