729 Copper Wire

Learn how Gee Hoe Seng Pte Ltd (GHS) handles the collection and recycling of 729 copper wires in Singapore responsibly and efficiently.

729 copper wires are widely used in electrical and industrial applications due to their high conductivity and durability. With a high copper content, these wires are highly recyclable when properly prepared for recycling.

Coiled insulated copper wires collected for recycling in SingaporeRecovered bare copper wires after removal of insulation from 729 cable wire in Singapore.

Is it Recyclable?

Yes — 729 copper wires are recyclable, but the insulation must be removed before recycling to recover pure copper efficiently.

Each 729 wire typically consists of seven strands of copper wire encased in insulation (e.g., 1.5mm², 2.5mm², 4mm², 6mm²). The copper core can be recovered and reused, while the insulation is treated through licensed waste channels.

At GHS, we process and recycle copper wires of all grades, ensuring that both valuable metals and non-recyclable residues are managed responsibly.

Why and What Parts Can Be Recycled?

Discover why copper wire recycling is valuable and how to prepare your wires for collection.

Here’s why recycling works

  • Copper is a high-value metal with strong demand across electrical and manufacturing industries.
  • Pure copper cores can be reused with minimal energy compared to producing new copper.
Recyclable
  • Bare copper strands (after insulation removal)
  • Clean, stripped copper without plugs or attachments

What limits recyclability

  • Mixed or contaminated wires (with other metals or debris) lower recovery value.
  • Burnt or oxidized copper reduces purity and recyclability.
Not Recyclable
  • Plastic or rubber insulation
  • Burnt wires

Note: You do not need to strip every strand yourself, but clean, insulation-free wires yield higher recycling value. Always ensure wires are free from other metals, plugs, or attachments before collection.

Additional Information
Clean, stripped wires command a higher recycling value due to purity and ease of processing.

How to Prepare Before Collection / Drop-Off

  • Strip insulation where possible – Use a proper wire stripper or utility knife to remove plastic insulation safely. If stripping is not possible, you may leave the insulation on — our team will process it at our facility. However, insulated wires have a lower recycling value due to additional handling and material separation.

  • Separate by type – Keep copper wires separate from other metals or cables.

  • Remove attachments – Detach any plugs, connectors, or non-copper parts before collection.

  • Do not burn insulation to remove plastic — this process contaminates the copper and makes the wires non-recyclable.
