Study Notes

Defining E-Waste

  • E-waste refers to discarded electrical and electronic devices, including computers, phones, tablets, and televisions.

Health Hazards of E-Waste

  • Exposure to e-waste can cause health hazards, including respiratory problems, skin diseases, and cancer, due to the presence of toxic materials like lead, mercury, and cadmium.
  • Improper disposal of e-waste can lead to environmental pollution, contaminating air, water, and soil.

Waste Management

  • Waste management involves the collection, transportation, treatment, and disposal of waste in a manner that minimizes its impact on the environment.

Approaches to Recycling in E-Waste Management

  • There are several approaches to recycling in e-waste management, including:
    • Refurbishment: repairing and reusing electronic devices.
    • Recycling: extracting valuable materials like copper, gold, and silver from e-waste.
    • Disassembly: breaking down devices into components for reuse or recycling.

Role of Stakeholders in E-Waste Management

  • Stakeholders, including governments, manufacturers, and consumers, play a crucial role in the environmental management of e-waste, as they can influence the production, consumption, and disposal of electronic devices.

Sources of E-Waste

  • The main sources of e-waste include:
    • Household appliances
    • Industrial equipment
    • Computing and communication devices
    • Consumer electronics

Common Materials Found in E-Waste

  • Common materials found in e-waste include:
    • Copper
    • Gold
    • Silver
    • Lead
    • Mercury
    • Cadmium

Characteristics of E-Waste

  • E-waste is characterized by its rapid growth, toxicity, and non-biodegradability.

Hazardous Materials in E-Waste

  • Hazardous materials found in e-waste include:
    • Lead in batteries and cathode ray tubes
    • Mercury in fluorescent lamps and switches
    • Cadmium in batteries and pigments
    • Brominated flame retardants in plastics

E-Waste as a Global Issue

  • E-waste is considered a global issue due to the rapid growth of the electronics industry, the lack of effective recycling and disposal mechanisms, and the transboundary movement of e-waste between countries.
