What to Do with Connected Devices (“smart home”) When They Are Replaced

Introduction

Connected devices, also known as "smart home" devices, are increasingly present in residential and commercial environments. When replaced, their disposal or reuse must follow specific regulations to ensure information security and minimize environmental impacts. This article addresses the best practices for the proper handling of these devices, considering current legislation and security aspects.

Legislation Applicable to the Disposal of Connected Devices

The disposal of electronic equipment is mainly regulated by the National Solid Waste Policy (Law No. 12,305/2010), which establishes guidelines for the integrated management and environmentally appropriate management of waste. According to Sinir (National Information System on Solid Waste Management), the handling of electronic waste must ensure proper destination, avoiding harm to the environment and public health (sinir.gov.br).

Data Decharacterization and Sanitization Security

In addition to environmentally appropriate disposal, it is essential to guarantee the security of information contained in replaced devices. For devices that store data, such as control hubs or virtual assistants, it is recommended to apply data sanitization techniques according to NIST (National Institute of Standards and Technology) standards, especially those published in Special Publication 800-88 Rev.1 (nvlpubs.nist.gov).

The secure disposal of storage media, such as hard drives embedded in devices, must be carried out through certified processes for destruction or irreversible cleaning, according to guidelines available in specific scheduling for sanitization (eletronicos agendamento).

Procedures for Disposal and Reuse

It is recommended that replaced devices be sent to collection points duly licensed for electronic waste treatment (eletronicos agendamento). These locations ensure the reuse of valuable components and the correct disposal of hazardous substances.

Reuse or donation should always consider the complete removal of user credentials and data, protecting privacy and mitigating risks of unauthorized access.

Environmental Impacts and Benefits of Proper Management

The incorrect disposal of connected devices can release toxic substances and heavy metals into the environment, causing contamination of soil and water resources. An efficient process of collection, sanitization, and recycling minimizes environmental impacts and contributes to the circular economy, as recommended by the PNRS.

Conclusion

The responsible disposal of replaced smart devices requires compliance with environmental norms and information security. Sending devices to authorized points and proper sanitization are indispensable practices for the protection of the environment and personal data.
