RECYCLING E- WASTE

                                     Recycling E Waste

Firstly I would like knowledge a welcoming to readers, hello, watup, how u doin, as this is my first post. I would like to demonstrate recycling e-waste, which is one of the green technology methods in recycling waste. E-Waste is waste from electronic equipment this includes computers, monitors, televisions, printers, scanners, video players and more including any technological device out of work or unable to use. 















In this section, highlighting the  process of recycling e-waste is a important knowledge in understanding e-waste. There are many companies in Australia collecting and then recycling e-waste, I'm going to focus on one of the top leading companies known as 1800 e-waste, which is a leading e-waste collection and recycling service.


There are a number of procedures followed in order to collect e-waste and recycle them, this procedure begins by the collecting of e-waste by trucks. The collecting of e-waste has a specific dates in a year, for example every 3 -6 months.  Most electronic waste goes through a recycling system called a WEEE, Waste Electrical and Electronic Equipment, which 95-98% is not only recycles, any data left on hard drives and memories are thoroughly destroyed.


The following is the method carried out to dismantle e- waste.

Picking Shed- This is the first step, all the items are sorted by hand and batteries and cooper are extracted for quality control.




Initial Size Reduction Process-  items are shredded as small as 100mm to prepare the e-waste to be thoroughly sorted. This is also where the data destruction takes place.





Secondary Size Reduction – the small debris is shaken to ensure that it is evenly spread out on the conveyor belt, before it gets broken down even more. Any dust extracted is disposed of in an environmentally friendly way.





Overband Magnet – using magnets, steel and iron are removed from the debris.


Metallic & Non-Metallic Content – aluminium, copper and brass are separated from the non-metallic content. The metallic can then be reused and resold as raw materials.


Water Separation – water is used to separate plastic from the glass content. Once divided all raw materials can then be resold.


This a diagram to help to further understand:












      Benefits of recycling E-waste
      • E-waste has a highly disadvantage aspect, but also a positive aspect as most of the electronic devices have a variety of materials and these include metals that can be recovered for future uses by dismantling and providing reuse possibilities, intact natural resources are conserved and air and water pollution caused by hazardous disposal is avoided. 
      • Recycling reduces the amount of greenhouse gas emissions caused by the manufacturing of new products.
      • Another benefit of recycling e-waste is that many of the materials can be recycled and re-  used again.
      • Materials that can be recycled include "ferrous (iron-based) and non-ferrous metals, glass, and various types of plastic." "Non-ferrous metals, mainly aluminium and copper can all be re-smelted and re-manufactured. Ferrous metals such as steel and iron can be also be re-used.  
      • Due to the recent surge in popularity in 3D printing, certain 3D printers have been designed known as FDM variety, to produce waste that can be easily recycled which decreases the amount of harmful pollutants in the atmosphere. The excess plastic from these printers that comes out as a by-product can also be reused to create new 3D printed creations.
      The process of recycling e-waste is time consuming and not simple, however is highly beneficial to the environment creating less pollution and making a green environment     spreading its green colour slowly everywhere.
