The evaluation of the waste of electric and electronic equipment (WEEE) collection masses in relation to the amounts placed on the market shows comparably low rates of about 43 to 45% in Germany for the last years. Since a minimum collection rate of 65% has to be achieved from 2019 onward, it is important to ask how the current low rates can be explained. In light of these low rates, the disposal behavior of consumers might play a significant role which is examined in this study. A survey was conducted at the end of February 2018 to assess the consumers' behavior concerning the individual disposal of WEEE. The residents' knowledge about the known return possibilities and the collection systems for WEEE were investigated and if disposal routes differ for large and for small devices. On top of that regional differences in disposal behavior within Germany were considered to explain in all the existing deficits in the collection rate. The consumer survey showed that predominantly regular routes for the disposal of WEEE are used and relevant quantities are not only physically "lost," but that there are also significant deficits in the monitoring itself.
