Nowadays, recycling processes became more and more important mostly due to the impressive
increase in the production of wastes and to growing attention to the environmental safeguard [23].
Electronic waste is made of a mixture of various metals, particularly copper, aluminium and steel, mixed
with various types of plastics, glass fibre-reinforced epoxy resin and ceramics [24]. Recycling of e-waste
is an important subject not only from the point of waste treatment but also from the recovery aspect of
valuable materials [25]. Many researches show that the major materials in e-waste are metals, plastics,
and glass. Recycling different materials need to have different methods. So in this paper, the recycling
methods of different components at home and abroad were introduced.
