• Addressing worker exploitation requires international cooperation and the promotion of fair labor practices in the e-waste industry

Illegal dumping in developing countries

• Some developed countries illegally export their e-waste to developing nations with lax environmental regulations
• This practice shifts the burden of e-waste management to countries that lack the infrastructure and resources to handle it safely
• Illegal dumping exacerbates environmental and health problems in these countries and perpetuates global inequalities

Responsible disposal methods

Recycling vs landfilling

• Recycling e-waste allows for the recovery of valuable materials and reduces the need for virgin resource extraction
• Proper recycling facilities use safe and environmentally sound methods to dismantle and process e-waste
• Landfilling e-waste should be avoided whenever possible, as it leads to resource waste and environmental contamination

Certified e-waste recyclers

• Certified e-waste recyclers adhere to strict environmental and social standards in their operations
• Certifications, such as e-Stewards and R2, ensure that recyclers follow best practices for e-waste management
• Choosing certified recyclers helps support responsible e-waste disposal and reduces the risk of environmental and social harm

Corporate take-back programs

• Many electronics manufacturers offer take-back programs that allow consumers to return old devices for proper recycling
