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 em...

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 environmen...

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 n...

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 understoo...

Active disassembly using smart materials is a concept developed at Brunel University for the design of assemblies with the built-in capability for easy separation of components for recycling on exposure to certain triggering conditions. Such assemblies incorporate shape memory alloy (SMA) actuators in the product housings. These actuators in the fo...

Active Disassembly Using Smart Materials (ADSM) is a concept that has been under development for several years. It is a system allowing host assemblies to readily separate for recycling, when they are exposed to certain triggering conditions. Active Disassembly technology has been used to disassemble vehicle parts to aid compliance with the End of...

This paper reports the preliminary to current development of Shape Memory Alloy (SMA) actuators within their application in ‘Active Disassembly using Smart Materials’ (ADSM). This non-destructive self-dismantling process is to aid recycling of consumer electronic products. Actuators were placed in single and multi-stage hierarchical temperature reg...

Active disassembly using smart materials is a relatively new technology. Extensive tests have shown that the technology works. Analysis of product categories indicates that plastics dominated products as well as precious metals dominated products are most likely to benefit from including active disassembly in their end-of-life strategies. The econo...

The aim of the work was to demonstrate an alternative to conventional end-of-life (EOL) disassembly strategies such as robotic or hand dismantling. This initial investigation reports the disassembly of consumer electronic products using smart materials in the design of embedded releasable fasteners. A series of products was tested in a variety of d...

Supporting the industry in the design process, the approach described in this paper provides a real design for environment (DfE), including cost aspects. The basis for this form of DfE are the experiences and the data gained in numberless life cycle assessment (LCA) and life cycle engineering (LCE) studies as well as know how in applying generic mo...

.The use of active disassembly using smart materials (ADSM) is an alternative that has the potential to be used for enabling a wide variety of consumer electronics that could be actively assembled, or self-disassembled nondestructively on the same generic dismantling line. This novel form of disassembly has shown considerable promise during the ini...

The European Union draft Waste Electrical and Electronic Equipment (WEEE) directive calls for the removal and separate treatment of liquid crystal displays (LCD). This aspect of the legislation will potentially have an important impact upon the future `End of Life' (EoL) processing of much WEEE. Active Disassembly using Smart Materials (ADSM) has b...

This paper reports initial results in the application of shape memory polymer (SMP) technology to the active disassembly of electronic products. The smart material SMP of polyurethane (PU) composition was employed. Created for these experiments were novel SMP releasable fasteners, with which it is possible to effectively disassemble products at spe...

This paper reports results the application of shape memory polymer (SMP) technology to the active disassembly of modern mobile phones. The smart material SMP of polyurethane (PU) composition was employed. Two different types of SMP fasteners were created for these experiments. With these smart material devices, it is possible for products to disass...

Industrial recycling is a practice of growing importance while impending `Take Back' European legislation and economic pressures are increasing. Landfill sites are becoming exhausted and the industry could benefit from a novel approach to recycling pre and post consumer waste. Cost constraints limit the number of different products that can be recy...
