“…With reference to some models of sensitivity analysis of the authors already cited in the Literature Review [42][43][44][45], we create a model for ELV and refrigerator recycling applicable in the Republic of Serbia. We test how changes in critical variables lead to changes in the CBA criteria, and what are the limits of changes in these critical variables at which projects are still acceptable for implementation (Tables 9 and 10).…”

“…Wan et al [44] apply sensitivity analysis in the field of ELV and indicate the high importance of state subsidies in the field of ELV recycling, which will be the basis for a comparative analysis of the research results in this paper. They apply sensitivity analysis to car recycling and analyze the impact of the number of state subsidies on the volume of recycling and its profitability.…”

“…They apply sensitivity analysis to car recycling and analyze the impact of the number of state subsidies on the volume of recycling and its profitability. Taking into account the costs of procurement, treatment, and transportation of used cars, Wan et al [44] point to the need to further stimulate financially this process. They test the optimal amount of financial support by using sensitivity analysis.…”

Modern consumer society uses an increasing number of products to meet its needs, which become waste after use, thus posing a serious problem that threatens sustainable development. Investment in waste recycling, due to a high level of non-financial benefits, is considered sustainable, especially in the End-of-life Vehicles (ELV) and Waste Electrical and Electronic Equipment (WEEE) recycling areas. The research objective of this paper is to test the sensitivity of the model for sustainable management of recycling projects by applying a cost-benefit analysis (CBA) to investment projects of car and refrigerator recycling in the Republic of Serbia. By testing the key risk factors of the above investment projects within the sensitivity analysis, the main aim is to determine the critical value of these variables in terms of the financial and social acceptability of these investment alternatives. The results obtained indicate that state subsidies have the greatest influence on defining the model of sustainable investment, especially in the field of e-waste recycling. The impact of other factors, the price of secondary raw materials and the social cost of CO2 emissions, is significantly smaller, but should certainly be taken into account when defining the optimal model of sustainable investment.

“…However, as far as we know, few authors take into account the impacts of recycling prices on the collected quantities of WEEE in the existing optimization models of OLND and CLSC, combined with a strategy of hybrid transportation mode. Our previous research has indicated that the recycling prices can seriously affect the recovered quantities of wastes, and plays an important role in improving performance of reverse logistics system as endogenous variables of model [26][27][28]. It is easy to see that in the case of poor environmental protection awareness, it is necessary to encourage the public to actively participate in recycling WEEE by increasing their recycling price [29].…”

Recovery of waste electrical and electronic equipment (WEEE) plays an important role in protecting environment and conserving resources. Design of a more efficient WEEE recovery system is an imperative need for the relevant decision-makers, such as alleviation of overcapacity or insufficient recycling in many developing countries. In this paper, we optimize the WEEE recovery network which is associated with recycling prices and government subsidies by a nonlinear mixed integer programming approach. An integrated model is first proposed to formulate a design problem of WEEE recovery network, being involved with collection centers, two types of transfer stations, processing centers, incineration plants, landfill plants, secondhand product markets, and government subsides. The recycling prices and the transported quantities of WEEE (the number of batches) are endogenous variables of the model, being subject to a number of practical constraints. For solving this model, an algorithm is developed based on the branch and bound method. Scenario analysis and numerical experiments indicate that: (1) appropriate capacities of transfer stations can be provided by the proposed model for designing an environmentally and economically efficient WEEE recycling system, especially for alleviating the existing overcapacity or insufficient recycle. (2) An optimal governmental subsidy can be obtained in virtue of the proposed model and algorithm. (3) Diversity of transportation modes and permission of more than one mode in the same delivery route can greatly reduce the cost of recycling WEEE. (4) Preferred awareness of environmental protection can increase the profit and the recycled quantities, as well as reduction of the total recycling cost.

The end-of-life vehicles (ELV) issue has become an essential topic in the fast-growing automotive industry. This study utilizes comprehensive content analysis to critically review the recent ELV research developments and underpinning issues in Malaysia. Fifty relevant ELV studies in Malaysia from the year 2006 to 2021 are selected and categorized based on three innovative sub-elements (product, process, system) of sustainable manufacturing. The literature review findings show that sustainable product recovery and recyclability issues in ELV treatments are still a major concern. Current studies overlook specific research on sustainable and integrated processes for ELV treatment. There is still lack of detailed ELV implementation framework equipped with the documented procedures and appropriate industrial practices in the ELV ecosystem to optimize the ELV supply chain. ELV policy is yet to be enacted in Malaysia, and public awareness of ELV is still low. There is inadequate alignment in ELV research developments with the current National Automotive Policy 2020 in Malaysia. The proposed integrated conceptual model will provide an extensive overview for scholars, policy-makers, and ELV stakeholders to implement appropriate actions to improve present ELV businesses in line with the public readiness to enact the potential ELV directives or legislation in Malaysia.
