- Published Date
In the second report of our urban mining series, we take a look at how sorted electronic waste is further refined to produce precious metals. However, such process produces harmful toxins, and thus licensed businesses must adhere to strict protocols for the sake of the environment and public health.
在我們城市礦山專題的第二集，我們將了解如何把廢棄物重新變成資源，但因為過程會製造出強烈的汙染，因此合法業者必須謹慎處理，才不會汙染環境並危害公共安全。
