Distribution Analysis on Steel Alloying Elements in the End of Life Vehicle Scrap Recycling Process

With rapid increasing of the vehicle population of China, The treatment of End-of-life Vehicle (ELV) becomes a serious social problem. Because the situation of ELV, labor cost and the condition of facilities of China are different from the developed countries, the technologies and the recycling process used by the developed countries can not be simply imported to China without any change. In this paper, the recycling processes of the developed counties are analyzed firstly. And then, the shortage and the advantage of the Chinese recycling factories are discussed. According to it, a scheme of ELV recycling process is presented. And three value analyzing models are illustrated which include: (1) model of ELV to raw materials; (2) model of intermediate scrap to product; (3) model of remanufacturing. In the end, the facilities used for EVL recycling factories based on this process are discussed too.

Selective Disassembly

For the purpose of recycling end of life product, Selective disassembly methods are most common used for dismantling the old product. Only some parts which valuable for remanufacturing or reuse are dismantled. In addition, the optimal disassembly sequence which created automatic by the computer will help to decrease the disassembly cost and increase the whole revenue of recycling process. However, the disassembly model are still cannot be composed by the computer automatic, that is, some of the work need be done manually. Especially, the priority information among the parts should be analyzed by the engineer. In this paper, an automatic method is presented by comparing the feature of the parts. And then, by extracting and analyzing mates in the assembly, the adjacent information is obtained. Adjacency information and priority information respectively expressed by adjacency matrix and influence matrix, which can be used to depict the hybrid graph model in matrix-form, achieving the automatically creation of disassembly hybrid graph model.

Recycling Techniques

In the present study, a holistic End-of-Life (EoL) Index is introduced to serve as a decision support tool for choosing the optimal recycling process among a number of alternative recycling techniques of CFRP waste. For the choice of the optimal recycling process, quality of the recycled fibers as well as cost and environmental impact of the recycling methods under consideration, are accounted for. Quality is interpreted as the reusability potential of the recycled fibers; that is quantified through the equivalent volume fraction of recycled fibers that balances the mechanical properties of a composite composed of a certain volume fraction of virgin fibers. The proposed Index is offering an estimated balanced score, quantifying a trade-off between the reusability potential of the recycled fibers as well as the cost and the environmental impact of the recycling methods considered.

Product Recycling

The significant environmental cost associated with management of products at the end-of-life has resulted in the emergence of ‘producer responsibility’ legislations to encourage increase in recovery and recycling practices. In the case of electrical and electronic equipment, one such legislation, namely the ‘Waste from Electrical and Electronic Equipment Directive’, requires manufacturers to assume financial and legal liability for recovery and recycling of their products at the end-of-life. The current recycling applications of electrical and electronic waste are often developed on ad hoc basis and mainly attributable to the hidden economic value within used products. However, owing to stricter regulations on end-of-life product recycling, it is now essential to evaluate the recycling costs and environmental benefits of reclaimed products and materials as well as the selection of appropriate recycling strategy. The present paper describes the initial investigation in the realization of a computer-aided recycling process planner for electrical and electronic products. The assertion made is that such a systematic approach to producing bespoke eco-efficient recycling process plans for individual products will significantly improve the value recovery from recycling activities.

Polymer Separation

Photovoltaic panels were included in EU Directive as WEEE (Wastes of Electric and Electronic Equipment) requiring the implementation of dedicated collection schemes and end-of-life treatment ensuring targets in terms of recycling rate (80%) and recovery rate (85%). Photovoltaic panels are mainly made up of high-quality solar glass (70–90%), but also metals are present in the frames (Al), the cell (Si), and metallic contacts (Cu and Ag). According to the panel composition, about $72 per 100 kg of panels can be recovered by entirely recycling the panel metal content. The PhotoLife process for the treatment of end-of-life photovoltaic panels was demonstrated at pilot scale to recycle high value glass, Al and Cu scraps. A process upgrade is here reported allowing for polymer separation and Ag and Si recycling. By this advanced PhotoLife process, 82% recycling rate, 94% recovery rate, and 75% recoverable value were attained. Simulations demonstrated the economic feasibility of the process at processing capacity of 30,000 metric ton/y of end-of-life photovoltaic panels.
