Evaluation of outsourcing companies of waste electrical and electronic equipment recycling

Abstract

An increasing number of companies have focused on reducing the amount of waste properly or gaining value from used products. Facilitating the reverse flow of used products from consumers to manufacturers is a difficult and expensive process depending on the product and transportation type and distance. Another alternative is to outsource these activities. Outsourcing management helps companies for better using of time, energy, labor, technology, capital, resources etc. Moreover, working with wrong partners effects manufacturers' financial and operational situations. In order to get the best services, manufacturers usually invite several outsourcing companies for providing their tenders and then select the best offer. In this stage, using mathematical decision making techniques may help decision makers to get realistic results. In this paper the proposed methodology integrates two multi-criteria decision methods for ranking alternatives. This methodology is applied to a mid-sized firm operating in the field of electrical and electronic equipment. The results indicate that the most important criterion is cost for determining the best alternative. Besides, as it can be seen from the results, the best alternative for the manufacturer is the second alternative. These results propose a guideline for manufacturers for selecting the best alternative. From the results it can easily be seen that this approach shows its potential advantage in selecting suitable alternative due to its sound logic and easily programmable computation procedure.

A Hybrid Fuzzy Decision Making Procedure to Select among Outsourcing Alternatives for Waste of Electrical and Electronic Equipment

“…They determined the best alternative as treating WEEE by using reuse and recycling methods. Kara [14] presented methodology integrates two multi-criteria decision methods to evaluate of outsourcing companies of waste electrical and electronic equipment recycling. Ciocoiu et al [15] presented AHP for the evaluation of implementation of WEEE management systems.…”

“…Before this, evaluation criteria and alternatives are determined. The criteria and sub-criteria have been determined with respect to related literature [12], [14], [30]- [32] and these experts' ideas can be shown in Table IV. Besides, Table IV shows the criteria weights obtained by fuzzy AHP process.…”

Proposal of Decision Criteria Based on Product Characteristics for WEEE Recycling in Romania: A Managerial Approach

“…Iakovou et al (2009, p. 331) propose a multicriteria selection matrix for recycling WEEE, that includes the following elements: residual/market value of the components, environmental costs of the product, weight of the product, amount of the same component in the product, ease and duration of the dismantling process. Kara (2011) mentions some hindrances that make recycling challenging for current manufactured products. One of these is the difficulty to gain all the necessary information to plan for the recycling evaluation.…”

Recovery of valuable metal concentrate from waste printed circuit boards by a physical beneficiation technology

“…A number of researches on the recycling of waste PCBs have been investigated in recent years (Huang et al 2009;Canal Marques et al 2013;Birloaga et al2013;Zhou and Qiu 2010;Xiu and Zhang 2010;Guo et al 2011;Park and Fray 2009;Yang et al 2012;Kara 2011;Das et al 2009;Hall and Williams 2007;Veit et al 2005;Eswaraiah et al 2008;Duan et al 2009;Zhan and Xu 2009;2011;Wu et al 2008). The common methods include dismantling, shredding, air separation electrostatic separation, triboelectrostatic separation, hydrometallurgy, and pyrometallurgy.…”
