E-scrap Recycling

Electronic scrap (also named e-scrap) mainly includes discarded household appliance like refrigerator, TV, computer, washing machine, printer, fax machine, cellphone, circuit board, hard discs, CD ect. With the development of electronic industry and information technology, and electronic products’ fast replacement, the problem of e-scrap has become one of the stringent problems which need to be resolved effectively and correctly. Every year the 20 – 50 million metric tons of electronics end up in landfills all over the world.

E-scrap not only contains hazardous and toxic chemical elements, but also contains many valuable metals, such as SILVER, GOLD TITANIUM, FOSSIL FUELS, ALUMINUM, IRON, TIN, AND COPPER. It has considerable benefits to recycle e-waste, for example, protect the environment; reduce the demand for new product and new raw material; recycling cost usually is lower than exploitation of natural resources. Circuit boards from the electronic appliances contains many valuable elements, such as golds, silver, platinum, copper, iron, aluminum ect. Among these metals, copper takes up the most proportion of the metals. There are statistics indicating that each ton of waste circuit board gold content is up to around 1000g and 300g, which can be extracted with high technology of recycling.

E-scrap Recycling normally includes disassembling, shredding, sorting of different material, and disposal of toxic parts. Shredding is a critical process for electronic waste recycling, as the main body of the electronic appliances usually is made of hard plastic, and the hard plastic needs to be shredded as the first step before it can be further processed to turn into plastic granules. Harden’s Shredding machines are powerful enough to shred all hard plastic shells generated from the electronic appliances. In addition, circuit boards in some recycling equipment are also shredded into smaller scraps for easier extraction of the valuable elements.

E-Scrap & E-Waste Shredders utilize a right angle drive, which results in a compact design that requires minimal floor space. Bearing protection prevents shredded contaminants from reaching the bearings through the use of false walls and seals. The size of the hopper and motors, along with the cutter profile, will depend on what is being shred as well as the required particle size and throughput. Harden’s e-scrap/e-waste shredders are designed for your specific application.
