The treatment process of PC cases can be basically divided into dismatling, shredding, classification, and refining. After regeneration, we can extract all kinds of metals, such as gold, copper, iron, aluminum and glass, plastic products, and other recycled materials. The monitors after dismatled will need one more treatment process which is "removal of fluorescent powder".
【EN】“Urban Mining” from properly recycled discarded IT equipment
According to the “The Global E-waste Monitor 2020”published by the UN, in 2019, approximately 53.6 million metric tons (Mt) of e-waste was generated, yet the veritable “Green Gold” was actually recycled at only 17.4% while the remaining 80% were buried or incinerated. However, discarded IT equipment contains precious metals and many reusable raw materials.
After the public has handed over the discarded IT equipment to the cleaning team and the recyclers, these are transported to the resource recycling treatment plants, where the valuable substances can be recycled, and the remaining which cannot be reused will be properly disposed of by qualified cleaning and disposal companies.
In 2019, the recycling rate of waste electrical and electronic equipment and IT equipment in Taiwan was 64%. The discarded items in life can be recycled and turned into available resources through different recycling processes. Take desktops or laptops as examples, they will be dismantled first and then decomposed into copper, iron, aluminum plastic and IC boards and other electronic wastes. Among them, IC boards and other electronic wastes will be further shredded and classified and then separated according to fiberglass resin powder, copper iron, tin, lead, and other metals. At last, after they are refined, precious metals such as gold, silver, palladium, etc. can be extracted.
Say goodbye to landfill! Correct recycling channels can turn discarded IT equipment into urban mines.
In order to encourage the proper recycling of discarded IT equipment, local ronmental departments hold incentive programs from time to time and set more diversified recycling channels.
How can we actually help discarded IT equipment such as laptops, tablets and keyboards become an urban mine and turn them into available reusable resources? First of all, we can bring them directly to the recycling vehicle or check if there are waste computer recyclers in the neighborhood. So far there are more than 500 recycling companies registered with the Recycling Fund Management Board, or you can call the toll-free line (0800-085717) to inquire.
There are eight items of waste information included in the list by the Environmental Protection Administration (EPA) of the Executive Yuan: mobile computers (including laptops and tablets), motherboards, hard magnetic drives, power supplies, enclosures, monitors, printers, keyboards, etc. They may cause soil and water pollution if not properly handled.
In response to the concept of "Urban Mining", in order to encourage the public to actively participate in the recycling of discarded IT equipment, the EPA and the county and municipal governments often provide incentives to encourage people to take out their old computer cases, printers, keyboards and laptops that just gather dust at home in exchange for gifts, points or vouchers. Therefore, people can also check their area before recycling whether there are any relevant incentive programs!
