Obsolete Technologies Still Generating Waste: Environmental Risks and Best Disposal Practices

Introduction to Waste from Obsolete Technologies

The improper disposal of obsolete technologies poses a significant challenge to environmental management and public health. Discarded electronic components may contain hazardous substances, contaminating soil and water, as well as creating risks to data security related to storage devices. This article addresses the main environmental risks associated with these wastes and highlights best practices for safe and efficient disposal.

Environmental Risks of Technological Waste

Old technologies often contain heavy metals such as lead, mercury, cadmium, and hexavalent chromium, as well as brominated flame retardants and other toxic compounds. When these materials are disposed of without proper treatment, the release of these substances can cause contamination of groundwater, soil, and the atmosphere, affecting ecosystems and human health. According to the National Solid Waste Policy (Law No. 12,305/2010), the responsibility for the proper management of this waste is shared between generators and public authorities.

Applicable Legislation and Technical Standards

The National Solid Waste Policy sets guidelines for the integrated and environmentally appropriate management of this waste, including reverse logistics. Furthermore, the Technical Standard ABNT NBR 16414 defines procedures for the collection and recycling of electronic waste. The National Information System on Solid Waste Management (SINIR) also provides guidance for planning and controlling waste.

Best Practices for Safe Disposal

To minimize environmental impacts and security risks, it is recommended to implement specific protocols for the disposal and treatment of these materials:

• Proper collection and destination: Use specialized collection points that ensure sustainable processing. To facilitate the process, organized electronic waste collection is essential to prevent irregular disposal.
• Sanitization and secure destruction of storage devices: Equipment such as hard drives must undergo approved destruction methods to prevent leakage of sensitive data. Specialized solutions are available via secure disposal of hard drives and media.
• Recycling and reuse: Technologies should be sent for recycling where metals and other materials can be recovered and reused, in accordance with current environmental regulations.
• Training and awareness: Training teams responsible for handling this waste is fundamental to ensure compliance with regulations and sustainable practices.

Reverse Logistics and Shared Responsibility

According to article 33 of Law No. 12,305/2010, the implementation of reverse logistics ensures that manufacturers, importers, traders, and consumers actively participate in the return of technological waste to the production cycle or environmentally appropriate final disposal, promoting the reduction of environmental impact.

Conclusion

Environmentally responsible management of waste from obsolete technologies is essential to mitigate risks to health and the environment. The adoption of best disposal practices, aligned with legislation and reverse logistics, enables greater control over this waste and fosters the circular economy. Utilizing specialized services for collection and safe sanitization significantly contributes to legal compliance and environmental protection.
