Electrical cables and wires: scrap sorting and suitable shredders

Segmentation of electrical wire and cable scrap is essential to optimize recycling and ensure compliance with current environmental regulations. This article discusses scrap separation techniques and the appropriate shredders for the process.

Importance of Segmentation in Electrical Cable and Wire Scrap

The correct segmentation of electrical cable and wire scrap has a direct impact on the efficiency of recycling and the reuse of the materials, especially the copper, aluminum and other metals present in their composition. Law No. 12.305/2010, which establishes the National Solid Waste Policy (PNRS), regulates the proper handling of this type of waste, requiring segregation and correct disposal according to the article 33 of the legislation.

Scrap Segmentation Techniques

Segmentation involves the manual or automated process of removing the metal parts from the plastic covering, as well as separating ferrous and non-ferrous metals. Physical separation can be done through mechanical processes, such as manual picking, magnetic separators for ferrous metals and electrostatic or optical techniques for non-ferrous metals.

Suitable Shredders for Electrical Cables and Wires

The ideal equipment for processing depends on the volume and specificity of the scrap. Industrial shredders, with blades designed to break through the plastic insulation without damaging the metal, are recommended. These shredders must comply with safety and energy efficiency standards, such as NBR ISO 14001, to minimize environmental impacts.

In addition, shredders that promote proper fragmentation facilitate the subsequent segregation of metallic and polymeric materials, optimizing the recycling process.

Legal and Environmental Aspects in the Processing of Cable and Wire Waste

According to the National Solid Waste Policy, the disposal of this waste must ensure minimal environmental impact, favoring reuse and recycling. Improper handling may constitute an administrative infraction, subject to the penalties provided for in the legislation.

Considerations on Safe Disposal of Electronic Media and Equipment

For waste containing media with data, such as hard disks, a safe sanitization process is recommended to avoid information leakage. Hard drive sanitization services are recommended to ensure the safe destruction of stored data.

Collection and Final Disposal Services

It is essential to use specialized services for the collection and correct disposal of e-scrap, following strict technical and legal criteria, as indicated in electronic waste collection with professional scheduling.
