E-waste covers all electronic devices that run on batteries or electrical currents. Recycling these products allows for the recovery of valuable materials and helps to reduce negative environmental impact. E-waste is collected through recycling bins, collection locations or electronics take-back programs and delivered to a specialized recycler. It is then sorted and processed into different components.
Manual Sorting
The first step in e-waste recycling is manual sorting. Items are placed into designated bins or electronics take-back booths and transported to the e-waste recycling plant. Once at the processing center, an inventory of each item is recorded. It allows the e-waste recycler to keep track of the products it receives and provides a way to trace the individual parts of each product back to their source. During this phase, hazardous chemicals are also removed from the waste. For instance, computer recycling services often involve dismantling and chemically treating components. This process can expose workers to dangerous substances like lead and mercury. Recycling e-waste recovers valuable materials, such as copper and gold, and reduces the energy required to mine and manufacture new ones. It also helps to prevent toxic waste and poisonous chemicals from entering our bodies, water, and soil while reducing greenhouse gas emissions and pollution. Moreover, it saves on purchasing and shipping new raw materials.
Shredding
The next step in e-waste recycling is shredding the materials that aren’t reusable or valuable. This process occurs in a large machine that breaks the devices into tiny pieces. The pieces are then categorized into core materials and components for further processing. It includes compounds like fluorescent light bulbs, UPS batteries and toner cartridges. These items can contain dangerous chemicals that destroy the machine or contaminate the environment once thrown away. After being shredded, metals are mechanically separated from other elements using magnetic and eddy current separation methods. A giant magnet will pull all ferromagnetic metals, including iron and steel, from the waste mix, while other metals are separated based on a physical law known as eddy current. It helps reduce the harmful environmental impacts of mining new metals for electronic products. It also saves energy for incinerating the waste and reduces greenhouse gas emissions and pollution.
Water Separation
E-waste recycling is one of the best ways to save our planet. This procedure aids in lowering the quantity of dangerous compounds dumped into the environment. It contributes to the production of new electronics, vital for our constantly evolving digital world. The first step of the e-waste recycling process involves collecting electronic products through collection bins, drop-off centers, or specialized e-waste recyclers. The items ordered are then sorted by type. It is done to ensure that the most reusable materials are recovered from the devices. Once the e-waste has been sorted, it gets shredded into small pieces to make them easier to separate. During this step, compounds that can’t be shredded or crushed, such as batteries, UPS battery systems, and toner cartridges, are removed manually. The shredded e-waste then goes through a magnetic separation process that pulls ferrous metals like iron and steel out of the mix. Once these materials are separated, they can be melted down and used to produce new devices.
Magnetic Separation
E-waste recycling is hugely important because when discarded materials are sent to landfills, they can leak, pollute and poison the soil and water. It has a massive impact on wildlife, human health and the environment. By recycling e-waste, we can recover precious metals like gold and copper, which are increasingly used to produce new electronic devices. It is why extended producer responsibility (EPR) was created – it means that the manufacturers of products are responsible for managing their waste at the end of their life. When the e-waste is shredded, it is passed under a giant magnet, which can pull out all ferromagnetic metals, such as iron and steel, while using eddy currents to separate the non-ferrous metals from the mix. It leaves a solid waste stream mainly consisting of plastic and glass. Water is used at this stage to purify, separate the different types of plastics, and hand-sort any obvious contaminants.
