What is E-waste? And how do we dispose of e-waste?
Benefits of E-Waste Recycling
E-waste recycling helps in reducing environmental pollution and health hazards. Recycling also reduces the consumption of raw materials and encourages reuse. To handle such a surplus amount of e-waste we need trained staff, this need generates jobs in this sector, therefore, creating revenue in return. A smart and well designed e-waste management system will reduce the need to expand on landfills and incinerators, thus, saving some land and reducing greenhouse gasses released through incineration.
Types of E-Waste:
It is absolutely crucial to understand how to segregate assets into different types of e-waste before disposing as they can’t be dumped with other wastes. The process of recycling e-waste is a tedious process, as many elements such as glass, plastic, metals, chemicals and equipment big and small need to be seperated.
1. E-waste Classification
Generally E-waste is classified into glass, plastics, ferrous and non ferrous metals, organic pollutants. Metals like gold, platinum, silver, copper are of commercial value. They are especially separated and segregated to be reused. Steel,iron, aluminum copper and precious metals are also present.
2. E-waste Composition
E-waste contains various harmful materials that can’t be released into the environment without special treatment. Metals like lead, cadmium, organic compounds like polychlorinated biphenyls (PCSBs), polybrominated diphenyl ethers (PBDEs), etc. need chemical treatment to neutralize their toxicity.
3. E-waste Components
During the shredding and sorting of recycling process, they get categorized into reusable material and components that shouldn’t be crushed. Batteries, UPS cathode tubes, fluorescent bulbs and similar components made of glass and chemical mixtures are separated carefully to prevent leaks.
