· Asian countries like India and China are the major countries, which get the e-Waste from all over the world for recycling purpose as the developing countries have less legislation rules for disposal. 9 There are several definitions for e-Waste, but the simplest definition for e-Waste is "any broken or unwanted electronic and electrical ...
· Also, India is struggling with 95% of the E-waste in the informal sector and only 5% of the E-waste goes under the formal unit. India and many other developing countries are having a large scope in the field-scale implementation of the bioleaching method due to the availability of the E-waste material in a bulk amount.
