The WEEE waste market is growing exponentially globally. It is estimated that the waste will touch 56 million tons per year in 2020, of which 12 million will be imputable to the countries of the European Union. From these data it is also easy to calculate the quantity of noble materials recovered at the end of the life cycle of the various WEEE. Suffice it to say that, on average, each ton of WEEE contains about 200 grams of gold, of which 14% is recovered.
