What You'll Learn
Plastic wire sheaths are not valuable for recycling
Copper is a highly valuable scrap metal due to its high conductivity, malleability, and corrosion resistance. It is commonly used in electrical wiring, roofing, plumbing, and other machinery. Recycling copper contributes to resource conservation and can be a way to earn some extra money. However, it is important to note that stripping the wire to remove the plastic sheath can be a time-consuming and potentially dangerous task. It can expose individuals to harmful fumes, sharp tools, and electrical hazards. Therefore, it is generally recommended to leave this process to professionals who have the necessary expertise and equipment to handle it safely and efficiently.
The process of stripping the wire can also impact the value of the recycled copper. Clean wire, which is free of any insulation, solder, or other contaminants, is considered high-grade copper and commands a higher price in the recycling market. On the other hand, coated wires and cables are worth less than stripped ones because it takes work to separate the copper from the plastic sheath.
Despite the challenges of recycling plastic wire sheaths, there are still some options available. For example, some electronics recycling centres may accept wire insulation for recycling. Additionally, it is possible to re-granulate and reuse PVC insulation, but this requires a large quantity of the same material and colour, making it feasible only for specific situations.

Stripping wire insulation is time-consuming and potentially dangerous
Stripping wire insulation is a time-consuming and potentially dangerous task. The process of removing the plastic or rubber sheath from wires can be tedious and difficult, and it requires time, effort, and costs. If you are looking to recycle your wires, it is important to note that the plastic sheath usually offers no value to you or the recycling facility, so you may want to strip it yourself to increase the return on your deposit. However, this can be a complex and time-consuming process, especially if you have a large volume of wires to recycle.
There are various tools available for stripping wire insulation, ranging from handheld cable strippers to mechanical cable insulation strippers, which can be expensive. It is important to choose a safe tool to avoid any potential dangers. Using a utility knife with a sharp traditional blade can be dangerous, as it may cause puncture or laceration injuries if it slips. Instead, consider using a safer alternative, such as a non-conductive, non-sparking, and non-magnetic knife or blade specifically designed for electrical work. These safer options will reduce the risk of injury to yourself and prevent damage to the wires.
Burning the insulation off copper wire is not only unsafe and potentially dangerous but also illegal in most places. When you burn insulated copper wire, you are burning rubber or plastic, which can release toxic fumes and pose a fire hazard. Therefore, it is crucial to choose a safe and appropriate method for removing wire insulation.
Additionally, the process of stripping wire insulation can be time-consuming, especially if you are working with a large number of wires or cables. It is important to consider the time and effort required to strip each wire individually. For example, if you are recycling old electronics or appliances, you may have to deal with a large number of wires, which can be a tedious and time-consuming task.
In conclusion, stripping wire insulation is a potentially dangerous and time-consuming task that requires careful consideration. It is important to choose the right tools and methods to ensure safety and efficiency in the process. While stripping wire insulation can increase the value of your recycled materials, it is essential to weigh the time and effort required against the potential benefits.

Recycling wire can be profitable
Firstly, scrap wire can be used for crafting purposes. By bending, twisting, and shaping the wire, you can create unique jewellery, home décor, or artwork. These creations can then be sold through platforms like Etsy, local markets, or online craft stores.
Secondly, scrap wire can be utilised in various do-it-yourself projects, such as creating garden trellises, wire sculptures, or hanging plant holders. There is a growing market for unique home and garden décor items made from recycled materials, which can be sold on platforms such as eBay or local classified websites.
Thirdly, by establishing relationships with professionals such as electricians and contractors, who are always in need of good-quality wire for their projects, you can supply them with scrap wire and earn a steady income.
Additionally, scrap wire can be recycled through specialised metal recyclers who focus on specific types of metals. By sorting and separating scrap wire according to type, you can fetch higher prices. It is important to note that stripping the plastic or rubber insulation from the wire yourself can increase its value, but this process is usually tedious and time-consuming.
Furthermore, the connectors found on the ends of wire scrap, even copper wire, can contain valuable metals such as silver, platinum, and cadmium. These precious metals can be reclaimed and sold at current trading prices.
Recycling wire not only generates income but also provides environmental benefits. By recycling scrap wire, we can minimise the need for resource extraction, reduce energy consumption, combat climate change, alleviate landfill burden, and stimulate economic growth. With the world's consumption of copper expected to double by 2050, recycling can play a crucial role in reducing the strain on the supply chain and preventing unnecessary environmental damage caused by mining.

Burning wire insulation is illegal in most states
Burning the insulation during the wire stripping operation can create other problems. Charring is one of them. Charred insulation is a defective condition as defined in IPC/WHMA-A-620, Page 3-9, Section 3.5. The charring means the insulation has been burnt and the burnt material is left behind. This charring is carbon and conductive, so depending on how secure it is to the wire, it can fall off and create a short. Additionally, if the wire is charred during the soldering operation, it will impact the insulation clearance dimension, which will then create a potential problem with insulation clearance.
Oxidation is another issue that can occur when burning wire insulation. If the wire strands become oxidized, they may not be adequately tinned or soldered. Only RMA or ROL0 fluxes can be used to tin these wires, and this flux is not strong enough to remove the oxides. As a result, the solder will not wet the wire strands.
Instead of burning wire insulation, it can be removed through a stripping operation. This can be done by hand with a razor blade or by using a specialized stripping machine. While this process can be tedious and time-consuming, it is safer and more environmentally friendly than burning. The plastic or rubber sheath can then be recycled for possible reuse.

Copper wire is 100% recyclable
When scrap copper is brought to a recycling facility, it is first separated into different types. Insulated copper wire, for example, is sent to a chopping line where it is broken into small pieces, and the insulation is removed. The plastic or rubber sheath is usually worthless to both the recycler and the person recycling, so stripping the wire beforehand can increase the value of the copper. However, this process can be tedious and time-consuming, and it may be dangerous if not done correctly. Therefore, it is often best left to professionals.
After the plastic or rubber has been removed from the scrap copper wire, the chopped-up bits are screened and run through a density separator. The copper pieces are then remelted and formed into new copper rods for wire production. The recycled copper is drawn into new wire for use.
Recycling copper wire is especially important due to the rising demand for copper. The world's consumption of copper is projected to more than double by 2050, and electric vehicles require about 2.5 times more copper than standard combustion engine vehicles. Additionally, developing countries are improving their infrastructure and adopting renewable energy sources, such as wind turbines and solar panels, which require copper wiring. Therefore, recycling copper wire can help meet the growing demand for copper and reduce the need for new copper mining, which can cause unnecessary and irreversible damage to the environment.
