2. What is E-Waste Recycling
• Electronic waste recycling is the process of
recycling and reprocessing of electrical and
electronic components of any machine that has
been discarded or regarded as obsolete.
• Some of the common E-waste are from
appliances such as Televisions, Radios, Microwave
ovens, DVD, Mobile phones, Electric cookers,
Heaters, computers, laptops, Washing machine,
Air conditioner, Camera.

3. Cont..
• Majority of this material contains heavy metals.
• The composition of E-waste is harmful to the
environment hence it is very important to dispose
them in a right way.
• Best alternate ways to overcome this issue is by
recycling the waste and reuse it.
• The recycling process guarantees safe disposal of waste
Electrical and Electronic equipment’s.
• Informal processing of Electronic waste leads to
environmental pollution and adverse human health
issues.

4. Recycling Process of E-waste
• According to UN report only 20% of waste is
recycled. E-waste contains toxic substances
such as Cadmium, Lead, Mercury, etc.
• It affects the whole ecosystem.
• Therefore recycling and reusing is very
important.

5. Process of E-waste includes
• Collection of E-waste
• Safe storage
• Manual dismantling and storing
• Automated separation
• Material Recovery
• Hazardous material segregation and recovery
• Recycled Material storage and Transportation

6. Main steps of processing in detail:
• The first step in recycling process is pre-picking of
items that don’t want to be recycled. That is those
items will not enter the shredding step.
• Next step is shredding where breaking of material
occurs.
• Third step is separation. This step is very tedious and is
separated into various sectors. By using cutting edge
technology such as eddy current, magnetic separation
and Optical identification.
• Final step is the output which ensures the recycled
product is perfect and of high quality.

8. Recycling Flow Chart
• Initially all the E-waste are collected from
Manufacturers, Consumers and given to the inbound e-
waste recycling.
• In this step all the external cables are removed and the
products with glass and without glass are separated.
LCD, Plasma, laptops are also separately removed.
• In Manual disassembly process all the batteries,
cartridges, polystyrene, Cardboard's are separated.
• Then the automated process continues. It requires
sophisticated technology and more automated
machines.

9. Cont..
• In automated process first step is shredding to
downsize.
• Next all the ferrous material available is removed
magnetically.
• Then the hand pickers remove all the circuit
boards and copper.
• Nonferrous metals are removed using Eddy
current technology.
• Metal detectors Detects and separates the
remaining metals.

11. E-waste Recycling Machine
• The volume, Method of inbound and outbound freight, quality of
commodity, Types of scrap is the main consideration for the layout,
processing and the equipment.
• The foundation thickness and construction should be reviewed
while installing heavy equipment’s.
• High material velocity, Minimal storage and efficient manual are the
must have items in the workplace.
• The most commonly used shredder is shaft shredder. Shredding
requires more maintenance.
• Any downstream separation system can be used to fit the shredder
and the particle size.
• It is important to design the machine as if any modification can be
done at the future.

12. E-waste Recycling Plant Cost
• Normally the cost is around 20 to 30 lakhs. But it
will change depending on the geographical
location and initializing amount.
• The cost includes the Building cost, Labour, Raw
material, Transport, Electricity and other
operational expenses.
• Machinery Cost will be nearly 40 lakhs.
• The revenue realization from operation is around
60-70 lakhs per month.

13. Advantages
• Reduces greenhouse gas emission.
• Reduces pollution.
• Protects Biodiversity.
• Reduces soil waste production and disposal.
• Conserves Natural resources.
• Provides sustainable source of raw materials
to industry.

14. Disadvantages
• Cost is high.
• Source separation is difficult.
• It is impossible to recycle 100%.
• The chemical bond is tough.
• Recycling uses plastics to attain high efficiency.
