The optimal reverse logistics network for consumer batteries in North America

Abstract

The recycling of household consumer batteries is gaining legislative support throughout North America. The intent of this thesis document is to provide a broad overview of the current North American reverse logistics network for consumer batteries. Topics discussed include the viability of recycling for particular battery chemistries, collection methods, recycling methods, the current legislative environment, and the incentives to participate in the reverse logistics network for the various stakeholders identified. This document culminates in the explicit high-level definition of the available reverse logistics networks and the execution of a global warming potential analysis for each network. It is shown that, of the two available reverse logistics networks, in terms of kg C02 equivalents generated per metric ton of batteries processed one network is approximately double the environmental impact of the other. However, despite the magnitude of this difference, in an overall context this difference may not outweigh other factors for consideration. These other factors include cost, materials recovered, and overall environmental impact which would consider ecosystem quality and human health. This research was conducted using available public information as well as interviews with key individuals who are directly participating in the reverse supply chains.
