E-Waste: A Global Hazard and Management Techniques

Abstract

Nowadays with the advancement in technology there is more and more use of electronic items and appliances, which results in e-waste. Waste due to electrical items (e-waste) includes the electrical waste of machines or the electronic appliances which are discarded after their use. E-waste is a source of a number of toxic chemicals that are harmful to the environment and nature. The purpose of this paper is to raise global awareness about e-waste and hazards related to it. Hence, this paper deals with the description of e-waste, the problems related with it, various methods to recover valuable items from e-waste, and its environment friendly disposal. Also from this paper we get to know about the best management techniques for waste, i.e. recycle and reuse, and we need to adapt proper management techniques for sustainable development. Otherwise, in the future, waste of electronics will be harmful.

Tailoring the Asymmetric Structure of NH2‐UiO‐66 Metal‐Organic Frameworks for Light‐promoted Selective and Efficient Gold Extraction and Separation

“…Gold has an irreplaceable position due to its efficient conductivity and sustainability, which is the most central component of electronic devices [2b, 3] . Selective adsorption and separation of gold through efficient means can effectively improve the reuse of gold and reduce the harm to human beings and the environment caused by electronic waste [1c, 4] . In general, materials with high specific surface areas have a high gold extraction capacity [5] .…”
