“…Firstly, the disposal-related analysis uses data obtained from official collection channels. Secondly, time series analysis extrapolates historical sales data into the future using historic lifespan data to estimate future e-waste generation and was used by References [41,[46][47][48]. Thirdly, factor models analyze relationships between factors like population size, income levels, GDP versus e-waste generation and was used in References [34,49,50].…”

"Universal access to electricity" is proclaimed as the seventh sustainable development goal (SDG 7) of the United Nations (UN) Sustainable Development Goals list. The achievement of this goal will result in a rapid diffusion of energy technologies that would in turn increase materials stocks, subsequently increase the raw material demand as well as the arising waste flows. This study describes a methodological framework to assess in-use stocks of off-grid solar products and electrical and electronic equipment (EEE) for rural communities in developing countries. The methodology is based on energy-access data. Furthermore, the specifics of the characteristics of off-grid solar products are discussed. The methodology is applied to rural Bangladesh and its solar home system (SHS) program. By the end of 2016, around 4.1 million SHSs were installed. This type of access to electricity has a significant impact on the in-use stocks, as households add the comparatively heavy SHSs to their in-use stocks. In-use stocks of EEE, in general, are low. Off-grid solar products are lighter than standard EEE, and fewer products types are available. These findings will help to better understand material stocks and future waste flows in the given context and will support the adaption of recycling infrastructures.

Material fl ow analysis (MFA, also known as Material Flow Accounting) has become one of the basic tools in industrial ecology, since its pioneering development by Ayres. This chapter reviews progress in MFA with emphasis on the use of MFA to support waste management and recycling policy.Waste statistics are compiled in most developed and some developing countries, but the basis is insuffi ciently standardized so that care is needed in making comparisons between countries. This also applies to recycling fl ows, which are diffi cult to defi ne and quantify. Waste arising from demolition can be predicted by dynamic modeling which also predicts future resource demand, but the discrepancies between predicted and reported waste quantities can be large due to "missing" or "dissipated" stock. Metals represent an important and valuable component of waste; metals in endof-life vehicles and e-waste in particular need to be quantifi ed for their recycling and ecological and human health impact assessment. MFA has also been applied to international trade of secondhand products containing metals. MFA studies on phosphorus have revealed potential ways to increase recovery that go beyond recycling from obvious wastes.

These data are intended as a snapshot of the year 2010, because the indium concentrations are of rapidly varying sizes and changing material compositions are common due to the short innovation cycles.…”

Abstract:Critical metals are in great demand by the electrical and electronics industry, so waste electrical and electronic equipment represents a significant source of secondary raw materials. Owing to low recycling rates and the concomitant supply risks associated with critical metals, the closure of the material cycles is highly relevant to the German economy. Losses of these metals occur from collection until their material recovery, along the entire disposal chain of waste electrical and electronic equipment. This paper develops planning criteria for the design of collection groups to achieve higher recovery amounts of such metals. The aim is to clarify what amounts of metals exist, both product--specific and on the market, how the dismantling of the products is constructed and how collection groups can be arranged with planning criteria oriented towards resource conservation. The analysis is a snapshot using the example of indium and selected products. A procedure is presented and findings identified which are transferable to various critical metals and to waste electrical and electronic equipment. The results show that grouping of products according to resource amounts and the dismantling effort enables forward--looking and resource--efficient planning of the treatment of every single collection group.
