Conventional leaching (extraction) methods for gold recovery from electronic waste involve the use of strong acids and pose considerable threat to the environment. The alternative use of bioleaching microbes for gold recovery is non-pollutive and relies on the secretion of a lixiviant or (bio)chemical such as cyanide for extraction of gold from electronic waste. However, widespread industrial u...

Electronic waste (e-waste) is one of the fastest increasing waste streams worldwide due to unprecedented growth of the electronics industry, rapid obsolescence and subsequent disposal of electronic devices. Printed circuit boards (PCBs), the central component of electronic devices, are highly complex. PCBs are an important resource of metals, and contain substantial amounts of copper, tin, lead...

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 wa...

Along with the rapid development of electronic products, there is a large amount of electronic waste, such as hundreds of millions of mobile phones and junk personal computers, which is not only a waste, but also a tremendous damage to the environment. The article presents a technique of reusing the electronic waste for the smart home monitoring system. It also describes how to set up the proto...

This paper compares the legislative difference of physical responsibility and economic responsibility in the developed countries and districts. Learning from the comparison analysis of the cognizance, we can find a proper way for China to determine the one who should undertake physical responsibility and economic responsibility, and the method of performance. In this way, we can make full use o...

Introduction Over the past 30 years, there have been many urban freight surveys undertaken by local authorities across the UK, in an attempt to understand freight issues at the local level (Allen et al., 2008). Many of these focused on the supply chains delivering ‘core’ goods to retailers whilst some made an attempt to go further and quantify the impacts of service vehicle activity to gain a m...

Management of e-waste is becoming a challengeable issue in today’s world. The increase of waste and the need for saving the environment are two global debates in the world. These managerial problems come as a result of technological advancements and globalization as global forces toward complexity. These global forces made e-waste management become a world’s priority issue followed by cleaning ...

E-waste is traded between developed-developing and between technologically advanced developing-developing countries. The push and pull factors are influencing import and export demand of e-waste. The ‘Basel Ban’ signatory both developed and developing countries are lax in ‘Ban’ enforcement as the transboundary movement of ewaste is a complementary need for them. The harmful effects of hazardous...

E-waste refers to both electronic and electrical waste materials; namely any items which rely on an electric current or electromagnetic fields in order to operate, and contain a hard-drive or significant electronic components and/or a printed circuit board. E-waste is outstripping the general growth of the municipal waste stream. Increasingly, smaller and cheaper electronic items are being disp...
