Electronic waste recycling involves collecting, dismantling, and processing obsolete electronic devices to recover materials such as metals and plastics. Most e-waste contains heavy metals that are harmful if improperly disposed of. The recycling process separates materials through manual sorting, shredding, and automated separation techniques like magnetic and optical processes. This allows for the safe recovery of materials while avoiding environmental pollution. However, only about 20% of e-waste is currently recycled.

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.
