随身英语The problem with disposable coffee 外带咖啡纸杯的“回收难题” 在现代社会中，外带咖啡纸杯很常见，但这些纸杯给回收工作带来了难题。尽管原则上它们是被回收了，但目前的回收的方式意味着几乎没有纸杯可被持续循环利用。不过，一些专攻创新的群体找到了可能解决此问题的方法。本集《随身英语》带你一探究竟。 Vocabulary: problems and solutions 词汇：问题与解决办法 Millions of us grab a coffee on our way to work. And when we do, it probably comes served in a branded, disposable, cardboard coffee cup. Once the coffee is done, just pop the cup into a recycling bin and forget about it. The cup will be taken away and turned into a new one for you to use again tomorrow. The system works, right? There’s a hitch. In the UK, we throw away an estimated 2.5 billion disposable coffee cups every year. And despite being recyclable in theory, in practice only very few of them are dealt with in a way that makes them sustainable. This makes them a bit of an obstacle. What throws a spanner in the works is the layer of polyethylene that makes the cup waterproof, and the lid, which is most often made of polystyrene. As a result, most of the cups end up in landfill. But there are efforts underway to tackle this issue. One company, Biome Bioplastics, has come up with a fully compostable, recyclable cup that uses natural materials, such as potato starch, as waterproofing. Mr Mines, its chief executive, believes that this is the first time bioplastic has been used for disposable cups and lids that have to cope with hot liquid. And they're still fully recyclable. |
