Abstract: The rate of generation of electronic waste (e-waste) has grown at such a rapid pace that the disposal has become a challenge to the environment. E-waste is processed by the formal sector in compliance with the E-waste (Management) Rules, 2016. However, a very active informal sector is present who processes the e-waste in extremely hazardous conditions causing extreme environmental damage. This study has made an attempt to identify this informal sector, their sites of operation, processes involved in the extraction of precious metals from printed circuit boards (PCBs) etc. The waste acid generated from the process has been characterized for the presence of heavy metals which are harmful to the environment. Inputs and outputs from the process have been identified and estimated to give a material balance so that the magnitude of environment damage can be understood. The water and waste water samples collected from the sites where the waste streams are disposed have shown that the water is unfit for consumption as it has high levels of heavy metals. Even the soil samples show high content of heavy metals, thereby making the soil unfit for agriculture. The study further examines the various methods available for the removal of heavy metals from the waste acid. Adsorption of multiple heavy metals with low cost agricultural waste as adsorbent has been examined and proposed for incorporation by the informal sector to reduce the damage to the environment. This PhD thesis would be useful in the management of e-waste for efficient, environmentally friendly methods to be adopted by informal sector, in the recovery of precious metals, thereby, reducing the environmental damage. newline newline
