Waste from electric and electronic equipment (WEEE) has been identified as the one of the priority waste flows by the European Union. Main reason of the increased interest in this waste flow is the fast growth of amount of WEEE, which is  the 3 times fastest then regular municipal waste. It can be said that WEEE is the fastest growing kind of waste. 

At the same time, WEEE is very complex and heterogenious waste which contains large amount of materials that can be recycled and reused on the one hand, as well as toxic substances on the other hand.

Modern electronic devices might contain more then 60 chemical subsatnces, most of which are toxic, as wel as precious metals which are a part of printed circuit boards. Therefore there has been a ban of use of several hazardous substances in electrion and electronic equipment (EEE) imposed by the European legislation since 2003. At the same time strickt collection and recycling targets of WEEE are set by this legislation.
