A rainbow refuse system 彩虹垃圾处理系统

Most of us need to make a better effort when it comes to caring for creation， and it is always great to see how different countries are playing their part. One town in Sweden is leading the way by showing us how garbage can be put to good use.

Eskilstuna， a town with nearly 68，000 residents（居民）， thanks to a rainbow refuse system， is sending zero rubbish to landfill. Because nearly all of the Swedish towns residents signed up to a seven?color?coded recycling system， over half of the towns waste is being recycled—already ahead of the EUs 50% target for 2020.

The system means that homes have six colorful bags that separate metal， food， plastics， textiles（纺织品）， cartons， and newspapers， and then a white bag for rubbish， such as items that cant be recycled. At the recycling plant， the bags are automatically sorted into different metal containers thanks to their vivid colors. The green bags containing food waste are converted into slurry（浆） that creates bio?gas used to fuel the towns buses.

The other bags are compacted（压紧） and recycled according to their materials and the plastic bags themselves are also recycled. There are further benefits， too. This kind of recycling necessitates just one garbage collection every few days， which means fewer traffic jams and less pollution and noise.

The only downside of the system is that rubbish that cant be recycled is burned， and although this is used to create energy， it does mean that further greenhouse gases are released into the atmosphere. The overall benefits of the rainbow recycling， however， are proof that with a little effort—and some impressive engineering—we can all do our part in caring for our Earth.

难句分析

The only downside of the system is that rubbish that cant be recycled is burned， and although this is used to create energy， it does mean that further greenhouse gases are released into the atmosphere. 这个系统唯一的缺点是对不可回收的垃圾进行焚烧，虽然这是为了产生能量，但这确实意味着更多的温室气体会被排放到大气中。
