Best answer: What materials are extracted from recycled e waste?

What can be made from recycled e-waste?

The circuit boards contain a wide range of precious metals like gold, silver, platinum and palladium. These can be recycled into jewellery or mobile phone components. Mobile phones: The precious metals found in phones can be reused in other electronic products.

What is being extracted from e-waste?

2.8 Recycling

Recycling is the process of extracting resources of value from e-waste. Here the equipment is disassembled and the valuable components are recovered and are used for manufacturing new products. This method is extensively treated in the next chapter.

What valuable materials are found in e-waste?

The electronic devices that surround you on a daily basis are built with many components that contain precious metals of gold, silver, copper, and palladium.

What two valuable elements are extracted from e-waste?

Abstract. The recycling of metals such as gold and copper from discarded end-of-life electronic waste (e-waste or WEEE) is an important aspect to the development of environmentally benign manufacturing processes that exhibit circularity in materials flow.

What are three products made from e-waste?

E-waste is a popular, informal name for electronic products nearing the end of their “useful life.” Computers, televisions, VCRs, stereos, copiers, and fax machines are common electronic products. Many of these products can be reused, refurbished, or recycled.
