One goal of the new European legislation set out in WEEE Directive 2012/19/UE is the promotion of WEEE re-use schemes. However, some authors are rather sceptical about the contribution of WEEE re-use schemes to improve resource efficiency. In order to evaluate and to design adequate policy instruments, some authors recommend the cost-benefit analysis (CBA) as a compulsory first step. In this context, the main contribution of this paper is to enlarge the empirical literature by providing a CBA of re-use schemes versus recycling processes of PCs. The analysis is made for Spain by quantifying in monetary terms the social damages of environmental impacts such as climate change, human toxicity, particulate matter formation, metal depletion, etc. Our results suggest that promoting re-use against recycling (and consequently the need for manufacturing a new PC from raw materials) may reduce environmental costs by 45.20 sic per PC. Those social benefits are mainly generated in the re-use preparation process and distribution activities, whereas the re-use scenario displays a worse performance in energy consumption. The difference in the distribution stage during the second life cycle originates from the fact that the ready to re-use product is produced locally, while the brand new product is manufactured and distributed from abroad, mainly Asia. These results provide valuable information to policymakers and think tanks willing to design support schemes for re-use over recycling operations. (C) 2017 Elsevier Ltd. All rights reserved.
