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.
Global elektron chiqindilar monitoringi hisobotiga ko'ra, faqat 2020 yilda dunyo bo'ylab 53 million tonna elektron chiqindilar hosil bo'lgan. Va u har yili o'sib bormoqda va 2030 yilga kelib 74 million tonnaga etadi. Biroq, faqat 10 million tonnaga yaqin elektron chiqindilar haqiqatda qayta ishlanadi, ya'ni biz metallar va boshqa qimmatbaho materiallarni, shu jumladan nikelni qayta ishlaymiz. Qolgan 43 million tonna elektron chiqindilar qayta ishlanmaydi, balki poligonga tashlanadi, qayta ishlangan materiallarning umumiy qiymati taxminan 55 milliardni tashkil etadi. Biz har kuni foydalanadigan mobil telefonlar, kompyuterlar, televizorlar, maishiy texnika va boshqa elektron komponentlar qoniqarsiz sharoitda qolmoqda.
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.
