“…In general, developed economies are more likely to have e-waste regulations and enforceable management systems in place, but paradoxically fail to match in volume and efficiency the amount of collected e-waste. It is hard to accurately measure this disparity due to insufficient reporting of opaque international trade in e-waste [45]. But it is claimed that only 15.5% of global e-waste generated in 2014 was reported as formally treated by national take-back programs and schemes.…”

Extensive usage, new designs, rapid upgrades and short lifespans of electronic devices has resulted in ever growing generation of electronic waste (e-waste) worldwide. Burgeoning volumes of e-waste are becoming a global issue of great concern with developing and poor economies rapidly catching up with developed nations. This article presents an overview of regulatory measures being developed and operated across Europe, Asia, Oceania, Americas and Africa. Developed economies are more likely to have e-waste regulations and enforceable management systems in place but are relatively inefficient in e-waste collection as compared to poor and developing nations. E-waste collection occurs through channels broadly described as formal and informal sectors. The formal collection occurs largely in developed economies often managed by waste management services operating within national or local e-waste regulations. Informal collection in Africa, China, India and other Asian countries encompasses a range of unregulated and unreported collection arrangements including door to door brokers between households and mid-level scrap dealers, dismantlers and repairers. The opportunities and challenges for the management of e-waste remain complex and vary depending on the local political, cultural and socioeconomic waste management issues. With recycling rates still below 20%, these need to evolve further for environmentally and economically sustainable management of e-waste.

“…The highest amounts of critical materials and precious materials are embedded into notebooks, tablets, and smartphones. It is suggested that the printed circuit boards from these e-waste streams account for 3%-6% of the e-waste mass, which contains more than 20 different types of metals including gold, silver, platinum, copper, and aluminum with a potential revenue of USD 23,568/ton [5,6].…”

Electrical and electronic products have become an integral part of the current economy and, with the development of newer technologies, the life span of these products are getting shorter. As a consequence, the volume of electronic waste is increasing drastically around the globe. With the implementation of new rules, regulations, and policies by the government, the landfilling of electronic waste has been reduced. The presence of valuable metals in the e-waste stream provides a major economic benefit for recycling industries but, due to the presence of hazardous materials, a proper recycling technique is required prior to the disposal of the e-waste. The total e-waste generated in Canada was 725 kt in 2014. There are several organizations currently working in various provinces to deal with the collection and recycling of e-waste. These organizations collected nearly 20% of the total e-waste generated in 2014. The collection rate for e-waste can be boosted by increasing awareness and by creating more centers to collect all kinds of e-waste. The collected e-waste is processed at local processing facilities mostly dealing with dismantling and hazardous material removal processes and then shipping the remaining material to a central location for subsequent processing.

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.
