Business PickupWhile there’s a general understanding that electronic waste is dangerous for the environment, few people are aware of what exactly makes it so hazardous. Also known as e-waste, discarded electronics and their components pose a growing environmental concern not only because of what they’re made of, but also because of their accelerated rate of usage and disposal. Here, we take a closer look at what’s inside e-waste and why it’s harmful to our ecosystems.
What are the hazardous components found in e-waste?
Devices like smartphones, tablets, and computers are mostly made from metals and plastics. Not all of these pose environmental hazards, but many do.
The following materials pose a direct risk to the environment and various life forms.
- Lead found in older monitors and TVs is considered neurotoxic and dangerous to the nervous system.
- Mercury, which is found in switches, fluorescent lights, and batteries, is harmful to the kidneys and nervous system.
- Cadmium, which is found in rechargeable batteries, is a known carcinogen linked to lung and prostate cancers.
- Brominated flame retardants, which are used in certain plastics and circuit boards, are linked to reproductive and developmental problems.
Besides these components, other materials in e-waste that aren’t immediately hazardous can still cause pollution. Many are non-biodegradable and could release harmful chemicals during decomposition.
What is the environmental impact of hazardous e-waste?
E-waste has far-reaching implications and can affect our ecosystems in myriad ways. First, there’s soil contamination; hazardous materials can leach into soil and affect plant life, as well as the species that feed off plants. Water can likewise become contaminated, as e-waste runoff contaminates water sources and the aquatic life that dwells in them, as well as the species that feed off them such as birds and other wildlife. Finally, the air becomes polluted when e-waste is burned and toxic fumes are released into the atmosphere.
Community exposure is a growing concern of hazardous e-waste as well. Proximity to e-waste dumping sites could impact local communities, while workers in informal or unregulated e-waste processing sites could also face health risks. This is especially a concern in developing countries, which often serve as e-waste dumping grounds.
How can we mitigate the risks of hazardous materials in e-waste?
Preventing e-waste contamination comes down to proper disposal. Proper recycling methods allow for the recovery of valuable materials in electronics as well as a reduced environmental impact. Yet, it’s not a simple fix, and will require the collaboration of lawmakers, manufacturers, and consumers.
To facilitate e-waste recycling, there must be increased legislation surrounding safe e-waste management, including advocacy for adherence to disposal and recycling regulation. Many countries and territories already have producer responsibility laws in effect, which require parties such as manufacturers and retailers to develop and implement practices for recycling of their electronics at the end of their lifespan.
Consumers can also play a role in preventing hazardous e-waste from making its way into ecosystems. Community e-waste collection programs can encourage participation in recycling initiatives and provide local citizens with the resources they need to dispose of electronics responsibly. Consumers can also make informed purchasing choices and support companies with environmentally friendly policies and practices.
