Swiss plastic recycling still has room for development
the number of recycled plastic bottles in Switzerland has definitely reached a record breaking height. However, the way of recycling is very single nationwide
white opaque milk bottles have another recycling method, and the milk chamber will take them back. Most of the packaging of food, cosmetics or other daily necessities is still sent to the waste incineration equipment
susanglttli of the Federal Ministry of environment said: "the guiding principle of Switzerland is: if there are clear environmental and economic benefits, we will recycle plastics"
"these recycled materials are of good quality and can be used to make new products, such as food packaging"
glttli said that it would be better if there were another plastic recycling method at the end of the experiment of corrugated pipe ring stiffness tester than throwing it into the garbage incinerator. Since 2000, inflammable and chemically unstable garbage has not been allowed to be incinerated by law
"all garbage can be burned. Plastic is the main source of energy. As long as it is not easy to collect and recycle plastic products, they can only be used as manufacturing energy," glttli said. Some communities in Switzerland have begun to try plastic recycling. Zug city has collected plastic products for several years. Residents can exchange 1.90 Swiss francs for a 40 liter bag that can hold shampoo bottles and other plastic products
this is cheaper than the ordinary garbage tax. Like many other cities and towns in Switzerland, Zug also has to pay garbage bag tax
however, the activity of "paying for recycling" has never been formally implemented, because Zug residents can throw away all kinds of plastic garbage free of charge. A worker will check the quality of the plastic before putting it into the garbage. All the plastic will eventually be sent to plastoil, a local enterprise responsible for refining the plastic into oil
"this has always been a pioneer project, and we will see whether it is correct in the future. But if we do nothing, we will not achieve anything," said hansschwarzenbach, head of "kihof" of Zug Recycling Institute
last year, the residents of Zug collected 256 tons of plastic waste, equivalent to 10 kg per person, and all were transported to plastoil refining company, which won the Zug Innovation Award in 2006
Bern, the capital of Switzerland, has been collecting plastics since 2005. There are 8 waste collection shops in the city engaged in this work. A total of 250 tons were collected in the whole year, corneliakissling, head of the Berne garbage collection project, said
"we have talked with many enterprises and they are willing to recycle plastics". The load is removed only when the deformation of the outer diameter of the sample in the vertical direction suppresses 50% of the original outer diameter. However, because the market price of old plastics fluctuates, it is not easy for enterprises to make profits from it
a new international research is needed to explore whether there are other methods and possibilities for enterprises and consumers to recycle plastics
redilo is responsible for this project, and its specialty is sustainable development resource strategy. Raymondschelker, redilo's business partner, asked:
"where is the potential? What can we do? What can be recycled? What has both ecological and economic significance? We need to see what other countries have done."
"there is no standardized solution and standard system. At present, the situation is somewhat chaotic. I hope our research can bring new knowledge"
in addition to household garbage, industrial products such as plastic barrels or plastic films and farmers' straw roll plastic packaging can also be recycled. Glttli said that if taxes are collected on these products, it can help with recycling
schelker said that he was glad that redilo could invite representatives of the state, local governments, recycling enterprises, waste incineration industry, plastic product enterprises and other important departments to gather together
"we are optimistic that we can make contributions to the plastic recycling work in Switzerland in the future," schelker said
