Recycling electronics is an important step businesses can take to recover value from their electronics, conserve resources, and contribute to global sustainability goals by taking an environmentally friendly approach to IT asset disposal.
The process to recycle e-waste has several stages to prevent misuse or environmental risks, ensure recovery of valuable materials, and support reuse and resale of components.
This guide explores what is involved in responsibly recycling electronic devices and the role you can play in conserving resources, reducing pollution, and promoting a healthier planet for future generations.
What is Electronic Recycling?
Electronic recycling refers to the process of recovering valuable materials from discarded electronic devices and ensuring that hazardous components are disposed of safely. Recycling e-waste is essential for managing electronic waste responsibly, protecting the environment, and conserving resources.
The e-waste recycling market continues to grow. Market Research Future valued the 2023 market at USD 30.4 billion in 2023 and projected it would grow to USD 34.5 billion in 2024. By the end of the forecast period, the market was expected to enjoy a compound annual growth rate of 13.4% to reach USD 94.2 billion by 2032.
Why is the e-waste recycling process seeing such growth? Several reasons can be considered, including:
- Rising usage of electronic equipment
- Shortening lifecycle of electronics
- More awareness of potential hazards associated with improper disposal or electronics ending up in landfills
- Increased recognition of the importance of making environmentally friendly choices
What E-Waste Should be Recycled?
The list of electronics that can be recycled includes a wide range of devices and components. Anything with an electrical plug, battery, or circuit board should be recycled to reduce waste and avoid environmental contamination. This includes:
- IT and telecommunications equipment (e.g., computers, laptops, smartphones, printers, scanners, batteries, modems, routers)
- Office equipment (e.g., photocopiers, fax machines, televisions, cameras, camcorders, audio equipment, power cords, chargers)
- Large appliances (e.g., refrigerators, washing machines, air conditioners, ovens)
- Small appliances (e.g., toasters, blenders, coffee machines)
- Lighting equipment (e.g., fluorescent tubes and lamps, LED bulbs)
Benefits of Recycling E-Waste
Electronic waste is a growing problem. The world’s e-waste generation is far outstripping the effort to recycle e-waste. According to the United Nation’s Global E-waste Monitor 2024, the world generated 62 million metric tons of e-waste in 2022. That would fill, “roughly enough trucks to form a bumper-to-bumper line encircling the equator.” Plus, the level of e-waste is projected to reach 82 million metric tons by 2030.
Yet, the report also said under a quarter of the world’s e-waste was properly collected and recycled in 2022. That meant electronic waste was rising five times faster than documented e-waste recycling.
Recycling helps reduce the volume of e-waste that ends up in landfills, where it can take up space and contribute to pollution. But that’s not the only advantage. Responsible electronics recycling yields a wide range of benefits, encompassing environmental preservation, economic stimulation, and adherence to regulatory standards.
Most electronic products contain metals, plastics, glass and other materials. Many also contain valuable metals like gold, silver, copper, and rare earth elements that can be recovered and reused.
The amount of e-waste generated globally is stunning. The U.S. Geological Survey estimates that recycling one million laptops can save the equivalent of the energy used to power more than 3,500 homes. Recycling cell phones also makes a difference. Copper (35,000 pounds), silver (772 pounds), gold (75 pounds) and palladium (33 pounds) are among the natural resources that can be recovered from one million recycled phones.
Proper recycling process prevents harmful substances like lead, mercury, and cadmium from contaminating the environment. These can leach into the soil and water if not properly disposed of, but recycling prevents these toxic materials from contaminating the environment. This reduces the risk of public health problems related to e-waste exposure.
Recycling e-waste decreases the demand for new raw materials. This helps to preserve ecosystems and reduce environmental degradation associated with mining activities.
Using materials recovered from e-waste in new electronics also supports sustainable manufacturing and reduces the amount of energy required to build new. For example, recycling aluminum saves up to 95% of the energy required to produce it from bauxite ore.
In many cases, organizations can recoup money invested in the purchase of electronic components and devices. Recovered capital can be invested in new innovations and technological purchases.
This process supports the economy by creating jobs in the collection, processing, manual sorting, and resale of materials.
Demonstrating a commitment to sustainability can enhance business reputation and appeal to environmentally conscious consumers. This is increasingly important as consumers are paying more attention today to whether a business is working to make the world a better place.
Growing awareness of the e-waste recycling process and its importance may encourage consumers and manufacturers to make more conscientious choices around electronics. Instead of rapidly disposing of devices in favor of the next, new offering, individuals or organizations might instead opt for more sustainable options.
This could mean making use of electronics for longer, encouraging manufacturers to use more sustainable products, or considering more carefully what usable components are available in every electronic.
Recycling helps businesses in many countries comply with laws and regulations governing the proper disposal of e-waste. This helps them to avoid fines and penalties while contributing to broader environmental goals.

The first step in e-waste recycling is collecting obsolete or discarded electronic devices. Some retailers and manufacturers offer take-back programs, but otherwise your organization will need to work with a certified ITAD provider to facilitate the process. Sophisticated providers can assess your devices for resale, reuse, repair, or recycling.
A certified electronic recycling company can help your organization track the types and quantities of e-waste collected to improve process efficiency and provide necessary reporting to comply with regulatory requirements.
Once all e-waste is collected, the next step is to sort items by type (e.g., computers, phones, or office equipment) to streamline the process. Detailed information is recorded for each device, including manufacturer, model, serial number, and asset tag. This crucial step enables certified recyclers to provide comprehensive reports to their clients on collected and processed items.
Devices containing sensitive data or any media undergo secure erasure in line with organizational data sanitization policies, adhering at minimum to the NIST 800-88 standard.
Next, devices are assessed for potential reuse, component recovery, or recycling. This evaluation determines their viability in secondary markets. Many devices, while obsolete for one organization, can serve others for years, supporting digital inclusion and ESG initiatives through donations.
For devices unsuitable for reuse, valuable components like processors, RAM, hard drives, screens, and keyboards are salvaged before final processing.
Further sorting occurs based on material composition – metals, plastics, glass, precious metals, and hazardous substances. For instance, devices rich in ferrous and non-ferrous metals are grouped together, while those predominantly plastic or containing harmful materials are separated.
Certain e-waste types contain hazardous elements that require special handling during processing. For example, batteries or cathode ray tubes need careful attention to prevent leaks or contamination.
E-waste containing toxic chemicals require specialized procedures to ensure both environmental and workplace safety.
This could include:
- Batteries (especially those containing lithium or lead) because they pose a fire risk and contain hazardous chemicals.
- Cathode ray tubes in older televisions and monitors, which contain a toxic leaded glass
Items that cannot be reused are generally shredded to facilitate recovery of valuable materials. Industrial shredders can efficiently break down electronic waste into smaller pieces, making it easier to separate materials out in the next stage.
This stage can generate dust and potentially harmful emissions. Typically, shredding is done in settings with dust extraction and filtration systems set up to contain particles and ensure safety while reducing environmental impact.
- Magnetic separation: Uses magnets to isolate ferrous metals such as iron and steel
- Eddy current separation: Magnetic fields induce currents to eject non-ferrous materials such as aluminum and copper
- Optical sorting: Uses cameras and sensors to sort out items like plastic or glass which can be detected by their reflectivity or color
- Density sorting: Items have different densities in a liquid medium (e.g., plastics float, metals sink)
- Air separation: Separates lighter materials from heavier materials and helps remove dust and other fine particles from the shredded waste
- Chemical processing: Metals such as gold can be recovered with chemical leaching processes.
- Smelting metals or dissolving metals in a solution and then sending an electric current through the solution to separate out impurities.
- Mixing metals with others to create a different useful material (e.g., combining copper with zinc produces brass)
- Identifying plastics by their polymer type to avoid mixing different types (e.g., HDPE or PVC)
- Decontaminating and cleaning plastics to rid them of impurities
- Melting down cleaned plastics into pellets or granules that can be used in production of new products
- Processing non-leaded glass into smaller pieces (cullets), which can be melted and reformed into new products
- Using chemical processes to dissolve metals and separate and purify precious metals
- Extracting rare earth elements using chemical extraction methods for use in new high-tech products, such as electric vehicles, wind turbines, and advanced electronics.
This entire process works to recycle, recover, and reuse as much as possible. Still, there will be non-recyclable and hazardous materials that require environmentally responsible handling to avoid risk.
Materials such as lead, lithium, cadmium, mercury, or asbestos may need to be stabilized with chemical to neutralize the harmful properties. Or they might be encapsulated in a stable material to prevent toxin release.
Additionally, any residual waste from the earlier stages of the process, particularly non-recyclable materials or contaminated substances, must be safely disposed of in accordance with environmental regulations.
