日本是一个资源相当匮乏的国家,其资源绝大部分依靠进口。而稀有金属的供应状况更是面临诸多困难。因此,该国将目光瞄准了隐藏在海水、手机电池和电子元件板中的稀有金属。据日本经济产业省的定义,在液晶显示器、手机和电脑的电池中使用的有包括铟、钴等在内的31种稀有金属。日本是个电子大国,如果将这些电子垃圾中含有的稀有金属数量估算一下,日本从另外一个角度上来说,真的是一个资源大国。 Japan is a country with rather scarce resources and its vast majority rely on imports. The supply of rare metals is even more difficult. As a result, the country has set its sights on rare metals hidden in seawater, cell phone batteries and electronic components. According to the definition of Japan’s Ministry of Economy, Industry, there are 31 kinds of rare metals including indium, cobalt and the like used in the batteries of liquid crystal displays, mobile phones and computers. Japan is an electronic power. If we estimate the amount of rare metals contained in these e-waste, Japan is really a resource-rich country from another perspective.
