Module-V
E-Waste Management
Syllabus
[Introduction, sources of e-waste, Composition and Characteristics. Need for e-waste management
concerning global perspective. Toxic materials used in manufacturing electronic and electrical products;
health hazards due to exposure to e-waste. Recycling and Recovery: Different approaches of recycling
(separation, thermal treatments). Hydrometallurgical extraction, pyrometallurgical methods and direct
recycling. Extraction of gold from e-waste (Explain the Principle and experimental procedure). Role of
stakeholders in the environmental management of e-waste; Ex - producers, consumers, recyclers, and
statutory bodies]
E-waste management:
Solid waste refers to all non-liquid garbage arising from animal and human activities that are
discarded as unwanted and useless. It can be categorized based on materials such as plastic, paper,
glass, metal, demolition materials, wood, pesticides, insecticides and organic waste.
Based on the source, the solid waste can be classified into three types.
i. Electronic solid waste (e-waste)
ii. Municipal solid waste
iii. Bio-medical solid waste
E-waste can be defined as electronic and electrical equipments/products that have become obsolete
due to the change in fashion, style, status and attaining the end of their useful life.
E-Waste Management is a planned process of collection, transportation and disposal of e-waste
materials in safe and economic manner. Everyday tons of e-waste is disposing at various landfill
sites and recycling units.
E-wastes are considered dangerous, as certain components of some electronic products contain
materials like mercury, lead, antimony, phosphorus etc., which are hazardous and poses threat to
human health and environment.
Sources: Discarded computers, televisions. VCRs. stereos, copiers, fax machines, electric lamps,
cell phones, audio equipment’s, DVDs, CDs, washing machines, microwave ovens, mother boards.
PCBs, batteries, etc.
E-waste Classification: The European Union Directive divides e-waste into the following
categories:
1. Household appliances: refrigerators, freezers, washing machines, clothe dryers,
dishwashers, vacuum cleaners, etc.
2. Information and Communication Technology equipment (ICT): minicomputers, laptops,
notebooks, printers, telephones and cell phones.
