在15年内,英国和其他国家应该会很好地建设大型工业综合体,以回收废物。垃圾这个词可能会失去它的意义,因为所有进入垃圾场的东西都会变成有用的东西。即使是最危险、最令人不快的废物也能提供能量。
最新的项目是以一座约有50万居民的城市为例,准确地发现哪些原材料进入其中,哪些材料流出。目的是了解如果在城外建一座废物回收厂,这些原材料中有多少可以提供。这家工厂不仅可以回收钢铁、铅和铜等金属,还可以回收纸张和橡胶。
另一个新项目正在进行中,目的是发现分类和分离垃圾的最佳方法。当这个项目完成后,垃圾将按如下方式处理:首先,它将通过锋利的金属棒,金属棒将撕开通常包装垃圾的塑料袋;然后,它将通过一个强大的风扇将最轻的元素从重的固体中分离出来;在那之后,创始人和滚轴将打破一切可以打破的东西。最后,垃圾将通过磁铁(磁铁), 这将去除钢铁碎片;橡胶和塑料将在最后阶段进行分类。
第一个大规模的大型回收工厂大概还有15年的时间。事实上,随着将垃圾运送到更远的垃圾场的成本越来越高,一些大城市不久将被迫建立自己的回收厂。
