In the past years the topic of WEEE recycling has gained more relevance due to increased production and reduced effectiveness in metal recovery. Therefore, new processing technologies are evolving today as result of the increasing heterogeneity of WEEE. Such is the case of pyrolysis as an upgrading and conditioning method for different types of complex scraps, which also facilitate further mechanical separation of metal as well as production of an alternative fuel source. In this work, it has been concluded that pyrolysis can be easily integrated as a preprocessing step in a resource efficient recycling route.
