Ailgylchu Nicel--Diogelu'r Amgylchedd

Feb 22, 2022

Think about the largest cruise ship. Imagine its weight again - it's actually over 100,000 tons. Think about 500 such cruises and their total weight. This amazing number is the amount of new e-waste that we generate each year.

Yn ôl yr adroddiad Monitro Gwastraff Electronig Byd-eang, cynhyrchwyd 53 miliwn o dunelli o wastraff electronig yn fyd-eang yn 2020 yn unig. Ac mae'n cynyddu bob blwyddyn, gan gyrraedd 74 miliwn o dunelli erbyn 2030. Fodd bynnag, dim ond tua 10 miliwn o dunelli o wastraff electronig sy'n cael eu hailgylchu mewn gwirionedd, hynny yw, rydym yn ailgylchu metelau a deunyddiau gwerthfawr eraill, gan gynnwys nicel. Nid yw'r 43 miliwn tunnell o wastraff electronig sy'n weddill yn cael ei ailgylchu ond yn cael ei dirlenwi, gydag amcangyfrif o gyfanswm gwerth deunyddiau wedi'u hailgylchu o tua 55 biliwn. Mae ffonau symudol, cyfrifiaduron, setiau teledu, offer cartref, a chydrannau electronig eraill yr ydym yn eu defnyddio bob dydd yn dod i ben mewn amodau anfoddhaol.

Electronic waste contains nickel, but the amount depends on the electronic components being recycled. Recycling is a complex process because nickel is an "affinity metal" that can be mixed with most metals. The content of nickel generally accounts for 0.5 to 2 percent of the total weight of components, which is much lower than that of copper and iron. Key properties of nickel are used in electronic products, for example, in MLCC. Precious metals such as gold, palladium, and silver are used less, but they have a greater monetary value. However, in the circular economy, we need to recycle as much as possible.
