Attero recycling pvt ltd explains that the nature of the material from which e-waste is made is one of the most serious issues when dealing with it. Polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), lead, mercury, polybrominated diphenyl ethers (PBDEs), brominated flame retardants (BFRs), and other valuable metals such as aluminium, copper, steel, iron, and the infamous plastic, are all found in e-waste. All of these materials require special treatment, and because they are hazardous in nature, they cannot be disposed of in landfills.
