Rainbow-coloured rubbish. This is the colourful（鲜艳的） waste（ 废弃物） created by a Swedish city with a unique（唯一的） recycling system. Like many cities in Sweden（瑞典）, Eskelstunna has an impressive（给人印象深刻的） recycling（回收利用） record. It met the EU's 2020 target of recycling 50% of waste many years ago. But almost everyone who lives here follows a strict（ 严格的） recycling policy（政策） at home. People are expected to sort（整理） their household（家庭） waste（ 废弃物） into seven separate categories, including food, textiles（纺织品）, cartons（纸板箱） and metal.

  But what really makes this system stand out is the bright colour code. The reason for this becomes clear at the city's recycling plant. The bags arrive all jumbled（混杂） up because they are collected altogether（完全） once a fortnight from outside people's houses. But thanks to those bright colours, scanners can select（挑选） the bags and separate（使分离） them efficiently（有效率地）. The food waste in green bags is processed（加工） on site into slurry to make biogas, which powers（激励） the city's buses. One of the benefits of this method of recycling is that there is less cross-contamination（污染）, so more of the recycled waste can actually be used to make new things.

  Like the rest of Sweden, Eskelstunna is committed（犯罪） to sending zero waste（ 废弃物） from its citizens（公民） to landfill. Waste that cannot be recycled is incinerated（把……烧成灰） at a local plant to generate（产生） electricity. This reduces reliance（信任） on fossil（化石的） fuels（燃料） but does create greenhouse gases. As countries around the world try to improve their recycling rates, some may look to Eskelstunna as an example to follow. As long as they think they can persuade（说服） their citizens（公民） to get busy sorting（整理） at home. People are expected to sort their household waste into seven separate categories（种类）.

Hi, thanks for watching all the way to the end of the video.
