Subject: Digital Technologies
Class: JSS 3
Term: Third Term
Week: 2
Topic: Recycling Digital Devices
Duration: 40 Minutes

1. Learning Objectives

By the end of the lesson, students should be able to:

• Explain the meaning of recycling digital devices.
• Explain the importance of recycling digital devices.
• Describe ways of refurbishing old gadgets.
• Identify opportunities for reusing digital devices and components.
• Distinguish between reuse, refurbishment and recycling.

2. Meaning of Recycling Digital Devices

Recycling digital devices is the process of collecting and processing unwanted or discarded digital equipment so that useful materials can be recovered and used to make new products.

Digital devices include computers, mobile phones, tablets, printers, monitors, digital cameras, routers and other electronic equipment. When these devices become outdated or damaged, they should not automatically be treated as useless. Some may be repaired or reused, while others can be processed to recover valuable materials.

3. Importance of Recycling Digital Devices

a. Reduces Environmental Pollution

Proper recycling helps prevent discarded electronic equipment from accumulating in open dumps, drains and other unsuitable locations. It also reduces the risk of harmful substances entering the environment.

b. Conserves Natural Resources

Electronic devices contain materials such as copper, aluminium, iron and certain precious metals. Recycling can recover some of these materials and reduce the need to extract additional raw materials.

c. Reduces the Amount of Waste

Recycling diverts suitable electronic waste from ordinary disposal sites and helps reduce the quantity of discarded equipment requiring disposal.

d. Saves Energy and Resources

Recovering and reusing materials can reduce the need for some new raw-material extraction and processing. The actual energy savings depend on the material and recycling method.

e. Creates Employment Opportunities

Collection, sorting, repair, refurbishment and recycling activities can create jobs for technicians, repairers, collectors and trained recycling workers.

f. Makes Devices Available for Reuse

Devices that still work or can be safely repaired may be reused by other people, including students and schools that need affordable digital equipment.

Key idea: Extending the useful life of a device through maintenance, repair and reuse can often delay the need to replace it. Recycling becomes important when equipment is no longer suitable for further use.

4. Methods of Managing Old Digital Devices

Old digital devices can be managed in different ways depending on their condition, safety and suitability for use.

Method	Meaning	Example
Reuse	Using a device again without major processing.	Passing a working keyboard to another student.
Repair	Fixing a faulty device so that it can work again.	Replacing a faulty computer power supply through a qualified technician.
Refurbishment	Inspecting, repairing, cleaning and testing used equipment to restore it to a usable condition.	Cleaning, testing and upgrading a used school computer.
Recycling	Processing discarded equipment to recover useful materials.	Sending obsolete electronic equipment to an appropriate recycling facility.
Responsible disposal	Sending unusable or hazardous electronic waste through suitable collection and treatment systems.	Taking an unsuitable electronic device to a designated e-waste collection point.

5. Refurbishing Old Gadgets

Refurbishment is the process of inspecting, cleaning, repairing, testing and, where appropriate, upgrading a used electronic device so that it can be used again.

Steps Involved in Refurbishment

1. Inspection: Examine the device to identify visible damage and faults.
2. Cleaning: Remove dust and dirt using suitable methods.
3. Repair: Replace or repair faulty parts where practical and safe.
4. Upgrade: Where compatible, improve components such as memory or storage.
5. Testing: Check that the device works correctly and safely.
6. Data protection: Remove the previous owner's personal data securely before transferring the device to a new user.
7. Reuse: Return the refurbished device to service or pass it to another suitable user.

Examples of Refurbishment

• Repairing a laptop and testing its keyboard, screen and battery.
• Cleaning and testing a used desktop computer before donating it to a school.
• Replacing a damaged phone screen through a qualified repair service.
• Testing a printer and replacing worn parts where practical.

Safety note: Students should not open power supplies, damaged batteries or other potentially hazardous components. Repairs involving electrical hazards should be handled by trained people using appropriate safety procedures.

6. Reusing Digital Devices and Components

Reusing devices and components helps extend their useful life and may reduce the amount of electronic waste produced.

Examples of Reuse

• Giving a working computer to a school computer laboratory.
• Using a compatible keyboard or mouse with another computer.
• Reusing a suitable monitor with a compatible computer.
• Using an old smartphone as an offline learning device, where it remains functional and secure.
• Passing working networking equipment to an organisation that needs it.

Conditions for Safe Reuse

• The device or component should be in a safe working condition.
• It must be compatible with the equipment it will be used with.
• Personal information should be removed before transfer to another user.
• Damaged batteries and other hazardous components must be handled appropriately.
• Devices that cannot be reused safely should be sent to a suitable recycling or collection facility.

7. The Recycling Process

The recycling process may vary depending on the equipment and the facility, but it commonly involves the following stages:

1. Collection: Unwanted digital devices are gathered from homes, schools, offices or collection centres.
2. Sorting: Equipment is separated according to type and condition.
3. Assessment: Suitable devices are identified for reuse or refurbishment.
4. Data sanitisation: Personal and confidential data is securely removed from devices before reuse or processing, using appropriate procedures.
5. Safe dismantling: Trained workers separate components using suitable tools and safety measures.
6. Material recovery: Recyclable materials are separated and processed.
7. Responsible treatment: Hazardous or non-recyclable fractions are sent for appropriate treatment or disposal.

Important: Recycling electronic equipment is not the same as simply breaking it apart. Proper recycling requires appropriate facilities, trained workers and safe handling of hazardous components.

8. Challenges of Recycling Digital Devices

• Lack of awareness: Some people do not know where to take unwanted electronic equipment.
• Limited collection facilities: Suitable recycling centres may not be easily accessible in every community.
• Cost: Collecting, transporting and safely processing electronic waste can be expensive.
• Data security: Devices may contain personal or confidential information that must be removed securely.
• Unsafe informal recycling: Unprotected dismantling or burning can expose people and the environment to harmful substances.
• Rapid technological change: Devices may become outdated quickly, increasing the volume of equipment people discard.

9. Ways to Promote Digital Device Recycling

• Educate students and community members about responsible electronic waste management.
• Encourage repair and reuse where practical and safe.
• Use authorised or otherwise appropriate e-waste collection and recycling services.
• Support school collection campaigns in partnership with responsible recycling organisations.
• Protect personal information before donating or recycling devices.
• Choose durable devices and maintain them properly.
• Avoid buying unnecessary electronic equipment.

10. Class Activity

Activity: Reuse, Refurbish or Recycle?

Study the situations below and state the most suitable action for each one.

Situation	Suggested Action	Reason
