The progress of technology in the world is persistently increasing the volume of waste electrical and electronic equipment (WEEE). In Togo, the national production of WEEE is growing rapidly, 6,400 tons in 2016 and 7,500 in 2019. In order to have local data on WEEE, this study has been carried out to know their composition and volume in the District Autonome du Grand Lomé (DAGL) and the city of Kara. To master the composition of WEEE, the study dealt with households, public and private services, WEEE traders, repairers and then collectors. Considering the volume, the study took into consideration households, public and private services and then EEE traders. To achieve our goal, the holder survey method has been adopted. Survey forms were designed following the slightly modified Directive 2012/19/EU. The Kobocollect application facilitated data collection. These data were processed by the IBM-SPSS Statistics 25 application. The production ratios and the volume of WEEE were determined. The results obtained show that the WEEE produced are part of those of the 10 categories of Directive 2012/19/EU. The production ratios in the DAGL and the city of Kara are respectively 0.39 and 11.38 kg/inhabitant in households, 0.026 and 15.43 kg/service then 1.38 and 152.6 kg/EEE trader. Among the respondents in 2023, 1.8 tons of WEEE were generated in the DAGL and 18.7 tons in Kara. Extrapolation of the results shows that at the household level, 853 tons of WEEE were generated in the DAGL and 1834 tons in Kara. This study made it possible to know the composition of WEEE and their volume in the DAGL and the city of Kara. These results could be a decision-making tool for local authorities for better WEEE management.
