Conference paper


The upcoming perilous waste, e-waste is a challenge for the environmental engineers to degrade it in an environmentally sound manner. Though various rules have been passed and various treatment processes have been developed, a standard operating procedure for the direct metal recovery from WPCB is yet a puzzle. Now the treatment methods like hydrometallurgy, biohydrometallurgy, pyrometallurgy, cryometallurgy and plasma torch treatment have been identified and still under research for efficient treatment. A study has been done to find out the efficient and fastest treatment and disposal of e-waste. Pyrometallurgy has been chosen as the area of study from various literature survey. It has been found that pyrometallurgy is the fastest way to treat e-waste and WPCB and convert it into purest metallic and carbonaceous forms. Optimisation study for the deterioration of e-waste has been done with the help of thermo-gravimetric analysis (TGA) to find out the efficient degrading temperature and it was found to be 950°C. A horizontal tubular muffle furnace has been used to convert the WPCB into the earlier stated forms. The residue left after the treatment process was found to be rich in approximately 65% metallic and 25% carbonaceous forms. These outputs can further be used directly in various applications. Though it has many advantages, the emission of toxic gases during the treatment process is a major disadvantage. Various control measures have been taken as a countermeasure.
