The Growing Environmental Risks of E-Waste
Environmental Risks
E-waste is toxic, non-biodegradable, and accumulates in the environment, contaminating soil, air, water, and living organisms. Harmful disposal practices such as open-air burning and acid baths, used to extract valuable materials from electronic components, release toxic substances into the environment.?
These methods expose workers to hazardous contaminants, including lead, mercury, beryllium, cadmium, arsenic, brominated flame retardants (BFRs), and polychlorinated biphenyls (PCBs). Long-term exposure can cause severe health issues, such as:?
A Call for a Circular Economy?
A 2019 report, "A New Circular Vision for Electronics – Time for a Global Reboot,"?advocates for a circular economy?approach, aiming to minimize waste and energy loss. The report is supported by the E-Waste Coalition, which includes ILO, ITU, UNEP, UNIDO, UNITAR, UNU, and the Basel & Stockholm Conventions Secretariats.?
Improper handling of e-waste results in a massive loss of rare and valuable raw materials, including:??Neodymium?– Essential for magnets in motors??Indium?– Used in flat-panel displays??Cobalt?– Crucial for batteries?
Currently, rare earth metals are rarely recovered through informal recycling. For instance, only 30% of cobalt is extracted, despite existing technology that could recover up to 95%. However, demand for recycled metals remains?high, especially for laptops, smartphones, and electric vehicles.?
Additionally, recycling metals is significantly more energy-efficient?than mining new ones:??Recycled metals?use 2 to 10 times less energy?than virgin metals.??Extracting gold from e-waste?produces 80% fewer carbon emissions?compared to traditional mining.?
In 2015, raw material extraction accounted for 7% of global energy consumption. Shifting towards secondary raw materials?in electronics can significantly support climate targets set by the Paris Agreement.?
E-Waste and Climate Change?
Every electronic device contributes to carbon emissions. For example, producing one tonne?of laptops?can release up to 10 tonnes?of CO?.?
Most of a device's carbon footprint occurs during manufacturing, even before it reaches the consumer. This makes it essential to:??Use low-carbon production processes??Incorporate recycled raw materials?Extend product lifespan to minimize waste?
Low Recycling Rates: A Global Concern?
Despite the increasing demand for electronic devices, global e-waste recycling rates remain?low:??EU:?The global leader in e-waste recycling, yet only 35%?is officially collected and processed.?Worldwide:?Just 20%?of e-waste is recycled, while the remaining 80% is undocumented, often ending up in landfills where it?remains?for centuries.?
As electronics become smaller and more complex, recycling becomes more challenging and expensive. A significant portion?of e-waste, particularly plastics mixed with metals and chemicals, poses severe environmental risks when improperly disposed of.?
The Urgent Need for Action?
The increasing volume of e-waste, coupled with low recycling rates, places a significant burden on the environment and the electronics industry. To address this growing crisis, we must:??Enhance e-waste collection and recycling infrastructure??Invest in advanced recycling technologies??Encourage responsible consumer disposal practices??Promote sustainable manufacturing and circular economy initiatives?
A shift towards responsible e-waste management will help reduce environmental harm, conserve valuable resources, lower carbon emissions, and create a more sustainable future.?
