Waste management is an important step towards protecting the environment from harmful products and the residue that is left over after their usage. E-waste is generated from electronic appliances like refrigerators, washing machines, irons, hairdryers, toasters, personal computers, laptops, printers, scanners, etc. The increase in the usage of electronic appliances and electronic gadgets has led to a rise in the quantity of e-waste generated. This e-waste, if not recycled, contains harmful chemicals like nickel-coated batteries, lead, etc., that are detrimental if mixed with other components of the environment.
Essential Features Of E-waste Recycling
Globally almost 20-50 million tons of e-waste is generated, and only 20% of it gets recycled, and almost 70% of toxic material in the waste dumping landfills comprises e-waste. Therefore, e-waste recycling is essential because of the increase in the usage of electronic products by consumers. The technology becomes obsolete with each passing day that has led to an increase in the number of e-products in the market. Thus, we need to recycle the amount of e-waste to promote a healthy and sustainable environment and reduce new products’ usage.
E-waste Recycling Process
The process of e-waste recycling has been explained below-
Collection and Transportation- The e-waste generated is first collected and brought to the recycling place where the main process of recycling has to be done.
Processing and Segregation- The collected e-waste is then shredded and sorted to segregate the waste components. The components like steel, plastic, aluminum, etc. are sorted after shredding their size for ease of recycling. Machines are used to separate the different components, but sometimes manual separation is also done for components like CRT of LCD televisions or toner cartridges of the printer.
Dust Extraction and Magnetic Separation- These two processes can be done separately or combined into a single process as the dust particles are required to be removed from the waste generated, and the components like steel are separated with the help of a magnetic force.
Water Separation- This process is essential as any amount of moisture might slow-down the recycling process or make the substances less effective.
Plastic Separation- The plastic from the waste is separately segregated to be sent to the plastic recycling companies so that they can use it to make bio-degradable products.
Purification Of Waste and Preparing It For Sale- The waste that is filtered out after the above processes are purified and then meant for sale or re-used in other electronic products for promoting a healthy recycling process.
Other Features Of Recycled Products
The products that are prepared after recycling old products are cheaper in comparison to the new ones. Thus, everyone has the opportunity to purchase e-gadgets at affordable prices. These products are biodegradable as they are prepared from recycled goods and thus are beneficial for the environment.
E-waste is gradually increasing over time, leading to the contamination of soil and water and thereby increasing pollution, causing harm to both health and the environment. Therefore, the government should initiate proper measures for effective e-waste recycling.
