The recycle of waste materials is interesting in the environmental aspect to reduce the amount of waste in landfill and to recover materials once it is represents a potential source of valuable metals. E-waste is a fast growing waste stream with complex composition. The printed wired boards (PWBs) are found in the most of the e-waste and the composite materials are ceramic, polymers and metals. The recycling of PWBs from discarded printers is an important aim to recover metals. Biohydrometallurgical is a process that may offer possibilities to recover metals from E-waste. This study evaluated the bioleaching of metals from PWBs using strains bacteria and consortium of bacteria from acid mine drainage (AMD). The bioleaching tests were performed in shake flasks at a temperature 30 °C and 170 rpm using PWBs from discarded printers in contact with bacteria. Metals concentration was determined by energy dispersive X-ray Fluorescence (XRF).
