The purpose of this study is the recovery and recycling of polymeric waste from electrical and electronics equipment out of service (WEEE) and stored in the open of environment. The high consumption of these equipments and the practice by some manufacturers of the planned obsolescence make this waste take a worrying extent in the degradation of the environment. The addition of the ABS polymer to this waste makes it possible to reintroduce them into the cycle of the production of raw materials by recycling. we proceeded by adding Acrylonitrile Butadiene Styrene (ABS) at 20, 40, 50, 60 and 80% to the WEEE Matix. The waste is washed and crushed beforehand and the ABS is used in the virgin state. The mixing was done first cold by placing the various constituents in a cylinder in random rotation, then hot extrusion. The preparation of the test samples was carried out without additives or compatibilizers by injection process after grinding of the extrusion product. The mechanical characterization of the samples showed that the introduction of WEEE in the ABS matrix generates small variations in the modulus of elasticity. The maximum elastic stress increases by 27% for the mixture (50%WEEE/50% ABS). Resilience also increases with the concentration of ABS in the WEEE matrix and reaches 90% for the mixtures (50%WEEE/50% ABS). Finally, we proceeded to the observation and readings of the fracture facies by scanning electron microscopy (SEM).
