What types of e-waste are recyclable?
According to UNITAR research, global e-waste generation is on track to grow by 32% to 82 million tons by 2032. With only 1% of rare earth element demands coming from e-waste, the e-waste recycling market has ample room for expansion.
Most types of e-waste can be harvested for rare earth metals or plastic, including the following:
- Computers and laptops
- Cell phones
- Circuit boards
- Printers, copiers, and other devices
- Keyboards, mice, and other accessories
Recycling electronics keeps valuable resources inside the production loop and out of landfills. We’ll discuss the different types of recyclable e-waste, the e-waste recycling process, and the baling wire products you need to recycle e-waste safely and efficiently.
Computers and laptops
Computers and laptops contain many recyclable components, including:
- Metals
- Plastics
- Glass
- Circuit boards
- Hard drives
- Processors/CPUs
- Motherboards
- Batteries
E-waste recyclers disassemble these devices and sort components by type. Some components, such as processors, circuit boards, hard drives, and batteries can be resold or reused without further processing. Otherwise, sorted components are collected in bins or bales and sold to other recyclers.
Cell phones
Some recycled mobile phones can be refurbished and resold as is. The rest are disassembled and shredded. A conveyor system equipped with magnets, fans, and eddy currents sorts shredded cell phone waste by material type. Precious metals are the primary resource recovered from the process.
Circuit boards
Circuit boards are components of computers, cell phones, server racks, and other industrial computers. After capacitors and batteries are removed, they are shredded and sorted by material. Circuit boards contain these valuable resources:
- Precious metals: gold, silver, platinum, palladium.
- Base metals: copper, aluminum, iron, nickel, tin, lead, zinc.
- Rare earth elements: neodymium, dysprosium, praseodymium.
- Other materials: plastics, glass fibers, ceramics.
Once sorted, these resources are sold by weight to recyclers and manufacturers.
Printers, copiers, and other electronic equipment
Office accessories, such as printers and fax machines undergo a disassembly and sorting process similar to computers. The main difference is that they produce much more recycled plastic.
Keyboards, mice, and other accessories
Computer accessories contain more plastic and rubber and less rare earth metals. Only about 10% of them are recycled since many people throw them away in the trash. Some manufacturers are raising awareness about accessory recyclability and recycling trends are tracking upward.
The e-waste recycling process
Here is the general process by which used e-waste materials are recycled and reused:
- Collection: Discarded electronic products are gathered from homes, businesses, and collection points.
- Transportation: Collected e-waste is moved to certified recycling centers.
- Inspection and sorting: Each item is examined for potential reuse or refurbishment, with devices separated by type and composition for appropriate processing.
- Removal of hazardous components: Batteries, mercury-containing parts, and other dangerous materials are extracted for specialized treatment.
- Manual disassembly: Larger items are taken apart and reusable parts are salvaged for refurbishment or resale.
- Shredding: Non-reusable items are fed into industrial shredders to break down e-waste into small pieces for easier separation.
- Separation of ferrous metals: Shredded materials pass under strong magnets that extract iron and steel from the waste stream.
- Separation of non-ferrous metals: Eddy currents remove aluminum, copper, and other non-magnetic metals. These valuable materials are collected for further processing.
- Separation of plastics: Density separation techniques segregate different types of plastics based on their specific gravity.
- Circuit board processing: Circuit boards are treated separately due to their complex composition. Chemical or high-temperature processes extract valuable metals.
- Recovered materials are refined: Extracted metals are purified through smelting or chemical processes, and plastics are prepared for reuse by cleaning and pelletizing.
- Glass component treatment: Leaded glass is separated from non-leaded glass.
- Remaining materials are handled: Non-recyclable components are processed or safely disposed of.
- Prepare recycled materials for reuse: Refined metals, plastics, and other materials are packaged for distribution to manufacturers for use in new products.
The near-infinite recyclability of most metals makes e-waste recycling an important component of sustainable manufacturing practices. Plastic and glass recycling keeps waste out of landfills and reduces virgin material demands.
What types of e-waste can’t be recycled?
Not all e-waste components can be recycled. These devices and components are either impractical or dangerous to recycle:
- Cathode ray tube (CRT) monitors and old TVs: These contain high levels of lead and are difficult to recycle safely.
- LCD screens containing mercury: These require special handling as toxic materials.
- Batteries, especially lithium-ion batteries: While some can be recycled, many types require special disposal.
- Components containing hazardous materials like lead, mercury, or cadmium: These need specialized handling and disposal.
- Some plastics: Particularly those with flame retardants or other additives are non-recyclable.
- Toner cartridges: While some parts can be recycled, the toner itself is not recyclable.
- Certain small electronic components: Due to their size and composition, they may not be economically viable to recycle.
- Heavily contaminated or damaged electronic parts: These may be too difficult to separate and process effectively.
- Some specialized or proprietary components: These may lack established recycling processes.
Recycling capabilities vary by location and available technologies. While many components of e-waste can be partially recycled, complete recycling of all materials in electronic devices remains a challenge.

By prioritizing e-waste recycling, individuals and organizations contribute to a healthier and more sustainable future and the circular economy model.
Best baling wire for e-waste recycling
Baling Wire Direct offers multiple wire options for baling e-waste and other recyclables. The best type of wire for baling e-waste will also depend on storage conditions and duration. E-waste bales are heavy, so a thicker gauge wire is best. For vertical balers, we recommend 11–12 gauge wire. For horizontal balers, we recommend 10–12 gauge wire, and for two-ram automatic balers, we recommend 10–11 gauge wire.
Here are some of the best options:
- Galvanized wire has undergone hot-dip galvanization to provide extra resistance against rust and other forms of corrosion. E-waste bales can have jagged edges and metal-on-metal contact, and e-waste is often stored outdoors for long periods, making galvanized wire a great choice for recycling e-waste.
- High-tensile wire is manufactured from high-carbon steel. It is a popular choice for baling e-waste due to its increased tensile and load strengths, which can handle the weight and expansive pressure of e-waste bales.
- Black annealed wire has a wax finish that helps it feed smoothly through high-volume automatic baling machines commonly used in e-waste recycling. Annealing improved the wire’s elongation traits, which allows black annealed wire to expand with dense e-waste bales.
- Single loop bale ties can be tied to different lengths to accommodate irregular shapes and inconsistent bale sizes. They work with manual horizontal and vertical balers. We offer both black annealed and galvanized single loop bale ties. Galvanized bale ties offer enhanced abrasion resistance for baled recyclables that are often handled roughly.
- Double loop bale ties are pre-cut to length. The double loop configuration accelerates the tying process, increasing productivity.
