Physics instead of chemistry

E-waste is one of the most recyclable, but at the same time technically most demanding waste streams worldwide. In view of rising raw material prices, growing quantities and stricter environmental require-ments, classic, chemical-intensive recycling processes are coming under increasing pressure. Reagent-free technologies based on physical separation principles promise higher energy efficiency, lower emissions and new ways in urban raw material extraction. The study "Review of Reagent-Free Electronic Waste Recycling: Technology, Energy, Materials and Spatial Effects" by scientists from Kazakhstan and Croatia analyzes the state of the art and evaluates industrial perspectives. The study was published in "Recycling".
