AbstractAn attempt has been made to establish anapproach and a methodology to quantify electronic waste(e-waste) in India. The study was limited to personal computers(PCs) and televisions (TVs) within the state boundariesof Delhi and in selected areas in the National CapitalRegion (NCR). Material flow analysis was used to establishan e-waste trade value chain, where cathode ray tubes(CRTs) were tracked in the e-waste dismantling stream ofthe CRT regunning process.The market supply method wasused to estimate the theoretical amount of e-waste for eachitem. Sensitivity analysis was carried out for PCs, using 5years and 7 years as the average life, and for TVs, using 10years and 12 years as the average life. Externalities such ase-waste entering the study area from outside were factoredinto the final e-waste analysis. Sensitivity analysis on theaverage life also factored in elements of active usage, reuse,and storage of electronic items and consumer behavior intoassumptions about the obsolescence rate in market supplymethod.A primary survey indicated an output of 1800–2100CRTs per day from all regunning units in the study area.This range validated the theoretical output for an averagelife of 7 years for a PC and 12 years for a TV. Using thisapproach, e-waste was estimated to reach 2 million unitsfrom the domestic market by 2010.
