Over time, Sweden has implemented a cohesive national recycling policy so that even though private companies undertake most of the business of importing and burning waste, the energy goes into a national heating network to heat homes through the freezing Swedish winter.
“That’s a key reason that we have this district network, so we can make use of the heating from the waste plants. In the southern part of Europe they don’t make use of the heating from the waste, it just goes out the chimney. Here we use it as a substitute for fossil fuel,” Ms Gripwall says.
Sweden’s heating network is not without its detractors. They argue that the country is dodging real recycling by sending waste to be incinerated. Paper plant managers say that wood fibre can be used up to six times before it becomes dust. If Sweden burns paper before that point it is exhausting the potential for true recycling and replacing used paper with fresh raw material.
Ms Gripwall says the aim in Sweden is still to stop people sending waste to recycling in the first place. A national campaign called the “Miljönär-vänlig” movement has for several years promoted the notion that there is much to be gained through repairing, sharing and reusing.
She describes Sweden’s policy of importing waste to recycle from other countries as a temporary situation. “There’s a ban on landfill in EU countries, so instead of paying the fine they send it to us as a service. They should and will build their own plants, to reduce their own waste, as we are working hard to do in Sweden,” Ms Gripwall says.
“Hopefully there will be less waste and the waste that has to go to incineration should be incinerated in each country. But to use recycling for heating you have to have district heating or cooling systems, so you have to build the infrastructure for that, and that takes time,” she adds.
Swedish municipalities are individually investing in futuristic waste collection techniques, like automated vacuum systems in residential blocks, removing the need for collection transport, and underground container systems that free up road space and get rid of any smells.
在过去的时间里,瑞典推行了一项连贯的全国性回收政策,这样一来,尽管私企承担了大部分垃圾进口和焚烧业务,产生的能源还是能用于国家供暖系统,在瑞典寒冷的冬天里温暖千家万户。
格里普沃女士表示:“这是我们建立这一区域系统的主要原因,这样我们才能利用垃圾焚烧产生的热量。欧洲南部的国家不会利用垃圾焚烧来提供热量,而是任凭热量从烟囱冒出去,我们则用它来替代化石燃料。”
也有人对瑞典供暖系统提出质疑。他们认为瑞典焚烧垃圾并不是真正的垃圾回收利用。造纸商表示,在烧毁前,木材纤维还可以循环利用六次。真正的回收是把用过的纸转变为新的原料,如果瑞典在还未充分循环利用前就烧毁纸张,它正在耗尽真正的回收的潜力。
格里普沃表示,瑞典的目标仍然是阻止人们第一时间就把垃圾送去回收站。瑞典有一项持续了好几年的全国性宣传运动Miljönär-vänlig,该运动宣扬修补、分享和重复利用可以让人们获益多多。
她表示瑞典从其他国家进口垃圾来回收只是暂时的。格里普沃说:“欧盟禁止成员国填埋垃圾,所以这些国家为了不支付罚款就把垃圾作为一项服务送到我们国家来。他们应该也将会建造自己的回收工厂,减少本国垃圾,就像我们在瑞典努力推行的一样。”
她补充道:“希望以后的垃圾会减少,需要焚烧的垃圾能在各国国内焚毁。不过如果想回收垃圾用来供热的话,需要区域供热和冷却系统,所以必须修建相应的基础设施,而修建时间会比较长。”
瑞典自治区都在各自发展未来主义的垃圾收集技术,比如居民区的自动真空系统免去了垃圾收运,还有地下装载系统,可以避免占用街道和各种气味。
