一座闪闪发亮的金属山静静地躺在一间院子里,高近10米,被8个大型仓库包围着。在它旁边放着100多个金属包裹,每个60厘米见方,重1.5吨。其间,几个工人搬运着金属货物进出仓库。他们搬运的是垃圾,但不是任意种类的垃圾,而是钢铁废料,出自水槽、管子、螺丝钉、刀叉和罐头等。废料被堆成一个小山,然后经过几个步骤变为一捆金属包裹。这些废料是不锈钢生产的重要材料,也是全球钢铁产业二手原料日益重要的来源。它不仅是一手原料的高性价比替代品,也能节
A shining metal mountain lay quietly in a yard, nearly 10 meters high, surrounded by eight large warehouses. Next to it stood more than 100 metal packages, each 60 cm square, weighing 1.5 tons. In the meantime, several workers carried metal goods in and out of warehouses. They carry trash, but not any kind of trash, but steel scrap, from sinks, pipes, screws, cutlery and cans. The waste is piled into a hill and then turned into a bundle of metal packages in a few steps. These wastes are an important source of stainless steel production and an increasingly important source of second-hand raw materials for the global steel industry. It is not only a cost-effective alternative to primary ingredients, but also a festival
