Sustainable production approaches are critical because of environmental impacts in manufacturing. Remanufacturing, a process of returning a used product to original performance specification from the customers' perspectives with at least "as new" product warranty, is a more sustainable production method. This profitable practice is poorly understood because of its relative novelty. This paper explains the potential of 'Active Disassembly' (AD) to enhance remanufacturing profitability proposing further research. AD enables rapid non-destructive self-disassembly at end of life and reduces component damage to increase remanufacturing productivity.

The development of sustainable production approaches is critical because of the link between environmental impact and manufacturing. Remanufacturing, a process of returning a used product to original performance specification from the customers perspectives with at least as new product warranty, is a strategy to reduce manufacturing's environmental impacts whilst boosting profitability. Remanufacturing is poorly understood because of its relative novelty in research terms, for example, in comparison to conventional manufacturing. If considered during the early stages of a product's design, active disassembly (AD) can be used to enable the rapid, non-destructive, self-disassembly of products at end-of-life. AD reduces component damage and so facilitates remanufacture. This article explains a potential way forward to fuse AD and Design for Remanufacture in addressing the goals of sustainable manufacturing. An initial investigation of an automotive electronic control unit is tested with a unique form of AD employing an interstitial layer. Future work is proposed. © 2014 Copyright Taylor & Francis Group, LLC.

Alternative production approaches are required because of conventional manufacturing's adverse environmental impacts. Remanufacturing returns used products to at least original performance specification from customers' perspectives and gives the resultant products warranties at least equal to that of new equivalents. Remanufacturing is relatively novel in research terms compared to conventional manufacture and recycling but often is more profitable than both. It would help manufacturers address competitive, environmental and legislative pressures by enabling them to meet pressing waste legislation while producing high-quality, lower cost products with less environmentally damaging end-of-life (EoL) and manufacturing modes. Remanufacturing is highly profitable in large, complex mechanical and electromechanical products but with conventional manufacturing and design modes not so in smaller products; particularly fast moving ones. However, effective waste management is urgently required for such products because waste electrical and electronic equipment constitutes the fastest growing EU waste stream and a large percentage of products being produced by major developing economies such as China are of this type. Active disassembly (AD) enables product non-destructive, self-disassembly at EoL and was invented to facilitate a step-change improvement in recycling. This research investigated the use of AD to extend profitable remanufacturing into small EoL electrical and electronic products. © 2010 Taylor & Francis.

Purpose - Smart materials (SMs) have the potential for facilitating active disassembly (AD). Select SMs are used in the design of devices to aid product disassembly. The purpose of this paper is to compare different AD approaches and highlight future work and potential. Design/methodology/approach - This work is a survey of the collated AD research employing only Smart and "made Smart" materials work from various published work in the field from companies and academia since its original invention. The introduction gives general discussion of AD with cost implications and how the technology could offer very lean dismantling. An overview of the history of the work is given with the context of the implications for the need for a technology like AD to retain critical materials. Findings - Besides a survey to date, comparisons were made of each AD technology application highlighting advantages and challenges. Comparisons were also made prior to this in alternative disassembly strategies to give context to the potential usefulness of the technology. Practical implications - Only AD with SMs or "made Smart" were highlighted with some considerations for potential candidates. Originality/value - A survey of AD work only employing SMs and "made-Smart" materials to date. Comparisons of each AD application were made highlighting advantages and challenges. Comparisons were made between AD and alternative disassembly strategies to give context to the potential usefulness of the technology. The conclusion included an overview of work with consideration for future work. A candidate technology with the most potential was discussed. © 2012 Emerald Group Publishing Limited.
