LIBS 1910: E-Waste Recycling - Environmental Science Presentation

This presentation defines electronic waste (e-waste) and explores the recycling processes involved in recovering valuable materials from discarded electronic devices. It highlights the increasing global concern over e-waste due to rapid technological advancements and the environmental and health hazards associated with improper disposal. The presentation discusses the environmental issues, such as the exploitation of natural resources, pollution from hazardous chemicals, and harm to biodiversity. It also covers the economic and social benefits of e-waste recycling, including energy savings, job creation, and the recovery of valuable metals. Furthermore, it addresses political and legal aspects, such as the export of e-waste to developing countries and the associated global trade and security concerns. The presentation concludes by emphasizing the importance of proper e-waste management and recycling to mitigate environmental damage and promote sustainable practices.

Electronic-Waste (E-Waste)
Recycling

Definition
 Also referred to as:
 e-waste or
 e-scrap
 Trash generated from broken, obsolete or surplus electronic devices.

E-Waste Recycling
 Entails the processes engaged to recover the waste to be used in new
products (Haque, 2018).
 The world has been experiencing large amounts of e-waste.
 Due to the rapid technological advancements.
 New technologies render old ones obsolete.
 422 million unwanted phones laid in people’s premises in 2015
(Mortillaro, 2016).

Cont’d
 Unused electronic devices usually end up in garbage collection areas.
 UN in 2014 confirmed that more than 41 million tons of e-waste was
disposed globally (Kraus, 2018).
 Only 40 percent of the e-waste was discarded properly.
 Electronic devices contain valuable materials such as gold.
 Such valuables can be reused even after the life-span of an
electronic.

Environmental Issues
 Limited exploitation of natural resources.
 The production of electronics causes much harm to the environment.
 Recycling saves the ecological system this burden
 Electronic devices contain hazardous and toxic chemicals.
 The danger increases when they are not disposed properly.
 Recycling is the safest way of disposing unused electronic products.
 Recycling minimizes mining activities.
 Mining is not only harmful the environment and individual miners.

Cont’d
 Recycling helps to preserve the ecological biodiversity.
 However, informal recycling processes could cause even more harm
(Kumar & Holuszko, 2016).
 Dismantling e-waste leads to environmental impacts even when done
effectively.
 The gas and liquids released in the process get their way in to the
atmosphere, the soil and ground Water.
 These toxics are harmful to both plant and animal species.

Economic and Social Issues
 Helps to create and maintain sustainable economies (Shirazi, Irani, &
Bener, 2016).
 Saves the energy that could otherwise have been used in new items.
 Results to the recovery of valuable metals such as copper, silver.
 Leads to minimal spending on energy and acquiring new materials.
 The e-waste associations provide employment for thousands.
 Decreased unemployment rates lead to lesser social malpractices.

Cont’d

Political and Legal Issues
 Export of e-waste to developing countries raises global trade issues.
 All exported waste should be screened for harmful substances.
 Brokers in the business export unscreened waste avoiding the costs.
 Developing countries end up acting as dumpsites for electronic
waste.
 Presents a possible security threats both to the countries exporting
them and the individual owners of the products.
