“…Links between metals in the natural resources-map to sustainable recycling of metals (legend top to bottom equivalent to rings from the inside to the outside) (Verhoef et al, 2004). tages: intensive shredding is very costly, and some types of joints cannot be destroyed by shredding (discussed in detail in the next chapter). Additionally, the liberation level of metal particles might partly decrease during shredding due to the intensive plastic deformation these particles undergo in the shredder (Aboussouan et al, 1999;Sander et al, 2002). Consequently, materials that were not attached can become entangled in complex three-dimensional shaped particles after shredding.…”

“…Studies on the characterisation of shredded streams and the effect of shredding equipment and parameters have been performed. (Zhang and Forssberg, 1997;Kirchner et al, 1999;Aboussouan et al, 1999). It has been also proposed to use particle mass distributions instead of particle size distributions to describe these streams (von Blottnitz et al, 2002).…”

“…concerning the product and component re-use strategy; to integrate some theoretical process modelling, e.g. as proposed for shredding processes [28,55,56] and sorting Table 13 Prioritised list of the product's hot attributes for each criterion for recovery of the TV set according to Scenario 2 Weight criterion (negative impact) processes [48,57,58]; such a modelling could be based on a statistical framework, as recommended in Ref. [8]; this should lead to better and more accurate understanding of recovery route performance; to suggest an evaluation method of recovery route availability at a certain time and place to be used by the recycling expert when selecting scenarios; to validate and expand, through empirical measurement, the database that includes the performances of recovery processes; to incorporate models that take into account the fluctuations in the prices of virgin and recycled materials; to suggest a model for the quantification of uncertainties in the recoverability assessment: this should help decisionmaking when choosing among a list of possible improvement opportunities.…”

Significant improvements in end-of-life complex product recovery can be accomplished when recovery aspects are better integrated at the design stage of products. This paper introduces a new method that should allow design teams to produce better recovery-conscious designs, i.e. to integrate the complexity and the variability of recovery routes and to make recoverability more tangible to designers. The main methodological aspects of the new method are presented based on an analysis of the strengths and weaknesses of existing methods. In particular, the original multiprocess modelling of recovery scenarios and the original quantitative, multicriteria and multiscenario assessment of the recoverability of a product are detailed. On the basis of the assessment results, a design team is able to suggest design improvements. The implementation of the new method is simulated in real industrial practice. It is shown how the use of the method can bring significant gains in the product's recoverability. Assets and drawbacks of the method are discussed.

Recycling retired cars can relieve the environmental pollution and resource waste efficiently. However, a few publications can be found on the failure mechanisms and optimization method of recycling equipment, shredders. Thus, the failure mechanisms and structural optimization of shredder hammers for retired cars are studied aiming improving shredding efficiency and reducing cost. Failure types of shredder hammer are studied theoretically, and it is found that wear failure and fatigue failure are the two main failure types of shredder hammer. The shredding process of metal scraps is analyzed by finite element method, and it can be divided into four stages based on the stress states: initial stage, collision stage, grinding stage and separation stage. It is proved that the shredding efficiency can be improved by increasing cutouts on the hammer head. Finally, it is determined that the hammer with two cutouts is the optimal structure for metal scraps, which can improve the shredding efficiency by 20% and lengthen the hammer life by 15%. This study provides scientific basis for the industry application and theoretical foundation for further research.
