How are the bags sorted once they arrive at the recycling plant?
Rainbow-coloured rubbish. This is the colourful waste created by a Swedish city with a unique recycling system. Like many cities in Sweden, Eskilstuna has an impressive recycling record. It met the EU’s 2020 target of recycling 50% of waste many years ago.
五顏六色的垃圾。這是一座瑞典城市用其獨特的回收利用系統製造的彩色垃圾。和瑞典的許多城市一樣，埃斯基爾斯蒂納在回收利用方面取得了令人讚嘆的成績。它在多年前就達到了歐盟 2020 年前回收 50% 垃圾的目標。
But almost everyone who lives here follows a strict recycling policy at home. People are expected to sort their household waste into seven separate categories, including food, textiles, cartons and metal. But what really makes the 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 up because they’re collected altogether, once a fortnight from outside people’s houses.
But thanks to those bright colours, scanners can select the bags and separate them efficiently. The food waste in green bags is processed on site into slurry to make biogas, which powers the city’s buses. One of the benefits of this method of recycling is that there is less cross-contamination, so more of the recycled waste can actually be used to make new things.
Like the rest of Sweden, Eskilstuna is committed to sending zero waste from its citizens to landfill. Waste that cannot be recycled is incinerated at a local plant to generate electricity. This reduces reliance on fossil fuels, but does create greenhouse gases.
As countries around the world try to improve their recycling rates, some may look to Eskilstuna as an example to follow – as long as they think they can persuade their citizens to get busy sorting at home.
