Treatment of Hazardous Substances


On roughly analyzing the constituent of e-waste, it is found that electronic equipments and electric appliances contain high amount of hazardous metals like lead which can cause nervous disorders. CRT of computer monitors and televisions are very difficult to recycle, owing to their non-biodegradable poisonous metal content. Lead is again one of the major constituent of CRT along with cadmium, beryllium and other flame retardant ingredients. Wires and cables are coated with PVC or polyvinylchloride for insulation which when disposed give out fumes of chlorinated dioxins and furans. Similarly flat screen televisions contain significant amount of liquid metal mercury which seeps into the soil, when these televisions are dismantled in an unauthorized and unsystematic manner. Mercury reaches the underground water and dissolves in the drinking water, ultimately causing neuro-disorders and deficiency in children and developing fetus. Cadmium, another component of monitors of computers, circuit boards and batteries is known to be carcinogenic. These toxic metals and other poisonous chemicals remain conserved in the soil and environment for a very long time and are not disposed off quickly. At E.Coli Waste Management Pvt.
