Waste Electrical and Electronic Scrap – Consisting of IT Equipments like CPUs, CRT/LCD Monitors, Laptops, Telecom Equipments, Mobiles, Printed
Circuit Boards, ICs etc
Transporting, Warehousing, Segregation and Dismantling

etc
All the above items each with a different material characteristic, metal composition, different hazard characteristic needs to be
recycled.
Recycling not only involves recovering the value added materials like Base metals, Precious metals, plastics etc. It also involves disposal of hazardous and non-recyclable materials like BFR, Fiber, Thermo-set Plastic etc. The Growing amount of these materials is forcing the government o encourage more formal recyclers and also formalize the informal sector.
Objective: Recycle all the above items in a Environmentally friendly process and obtain Maximum Efficiency

Pyrometallurgy
•This involves Smelting of the materials like PCBs, ICs, Directly after dismantling and mechanical crushing. Recovery of Base metals and Precious metals by using Hydrometallurgical Refining techniques.
•This Technology is being Used Across the world by several refineries for the efficient recovery of base metals and precious metals.
•The Processing Capacity is very Large.

Presence of BFRs, Plastics, PVC, PCB, Polymers etc during Presence of BFRs, Plastics, PVC, PCB, Polymers etc during smelting will cause emission of Dioxins, Furans, CO, CO2, smelting will cause emission of Dioxins, Furans, CO, CO2, NOx etc. NOx etc.
Ineffective process control might cause the liberation of Ineffective process control might cause the liberation of Dioxins. These pollutants are the most harmful substances Dioxins. These pollutants are the most harmful substances which results in the Ozone Layer Depletion, Global warming which results in the Ozone Layer Depletion, Global warming and also have severe health hazards. and also have severe health hazards.

non metallic materials
Separate non-metallics from metallics.Non metallics can be recycled
into products
Limited amount of non metallics being
put into the process thus reducing the danger
of harmful fumes being released
to the atmosphere
Hydrometallurgy
•This involves a series of processes where there is separation of metals, non metals etc.
• Various metals will be recovered by using chemical refining techniques.
•The Processes are usually done in Batches and the processing capacity is lesser as compared to pyrometallurgy, but there is better traceability.
