Summary The remaining value within end‐of‐use/life hard disk drives (EoU/L HDDs) is often not optimally recovered. The improper collection and recovery of HDDs contribute not only to rising environmental and social concerns worldwide, but also to the transformation of the economy and a significant loss of value. Currently, the most preferred treatment option for used hard drives is to recover the metals with the highest recycling effectiveness, such as steel and aluminum, via a shredding‐based recycling process that results in both value and material leakages. The complexity of retrieving the remaining values within EoU/L HDDs demands a larger view of the global supply of HDDs available for recovery. The aim of this paper is to first identify the geographical patterns of transboundary global shipments of new and used HDDs between developing and developed regions, and then capture and quantify the value leakage by bringing several unique perspectives. Two analyses have been conducted. First, the loss of value due to the insufficient recovery of neodymium (Nd) at the global level is quantified. Second, the value leakage as a result of the delay on on‐time reuse of HDDs is captured. Furthermore, the central challenges toward proper recovery of HDDs, where consumer electronic industry can make significant contributions, have been identified. HDDs are well positioned to contribute important insights to the recovery of other electronic devices, so the findings from HDDs can be adopted for other types of electronics.

Today is the age of evolution of technology; Innovation will be the key to success in this era of rapid technological advancement and adoption in every area. But matter is that how to make efficient to conventional technology or to make it advance such technology. In present scenario global environmental and energy problems, high expectations exist for solar power generation directly result in to reduce carbon dioxide generation by the primary use of fossil fuels. On the other hand domestic power consumption demand arising day to day. Our aim is to demonstrate solar energy to design smart solar inverter to utilize scrap e-waste. E-waste production is increasing day by day with least solution to reuse it for other purposes. E-waste can be a heavy part of future problems. The inverter is made by the help of most of e-waste material. This 500W solar micro inverter consists of three portion: the MPPT (Maximum Power Point Tracker) the DC-to-AC step-up converter and the AC-DC Inverter sections. In this paper, the attachment of hi-tech application (Data Acquisition System) using ESP8266/32 & sensor which helps to monitor temperature, battery position & light position to protect overall system environmental-friendly. Environmental friendly term hype for which the paper and the device totally support it, with equal importance. At the end, the inverter made up of e-waste but also with the application of IOT (Internet of things) can help to control the inverter from anywhere and regulate our safety concerns.
