"1" Pete

Mineral water bottles, carbonated beverage bottles and beverage bottles should not be recycled with hot water.

Usage: High temperature resistance of 70℃, only suitable for filling warm drinks or frozen drinks. It is easy to deform when it is filled with high-temperature liquid or heated, and harmful substances will be dissolved out. Moreover, scientists have found that after 1 plastic products are used 10 months, DEHP, a carcinogen, may be released, which is toxic to testicles.

"No.2" high density polyethylene

Cleaning products, bath products.

If the cleaning is not thorough, it is recommended not to recycle.

Usage: It can be reused after careful cleaning, but these containers are usually not easy to clean, leaving the original cleaning supplies and becoming a hotbed of bacteria. You'd better not recycle them

No.3 polyvinyl chloride

It is rarely used in food packaging, and it is best not to buy it.

"No.4" low density polyethylene

Plastic wrap, plastic film, etc.

Don't put plastic wrap on the surface of food and put it in the microwave oven.

Uses: heat resistance is not strong. Generally qualified PE plastic wrap will melt when the temperature exceeds 1 10℃, leaving some plastic preparations that cannot be decomposed by human body. Moreover, food is wrapped and heated with plastic wrap, and the oil in food can easily dissolve the harmful substances in plastic wrap. Therefore, before putting food into the microwave oven, you must first remove the wrapped plastic wrap.

"No.5" PP

Microwave oven lunch box.

When you put it in the microwave oven, take off the cover.

Usage: The only plastic box that can be put into the microwave oven can be reused after careful cleaning. It should be noted that some microwave lunch boxes are indeed made of No.5 PP, but the lid is made of No.0 PE/kloc-0. Because PE is not resistant to high temperature, it can't be put in the microwave oven with the box. To be on the safe side, open the lid before putting the container in the microwave oven.

No.6 PS

Bowl instant noodle box, fast food box.

Don't cook bowls of instant noodles in the microwave oven.

Usage: Heat-resistant and cold-resistant, but it can't be put into the microwave oven to avoid releasing chemicals when the temperature is too high. Moreover, it can't be used to hold strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene which is bad for human body and easy to cause cancer. Therefore, you should try to avoid packing hot food in fast food boxes.

No.7 personal computer

Other categories: kettle, water cup, milk bottle.

Uses: A widely used material, especially in milk bottles, is controversial because it contains bisphenol A. Lin Hanhua, an associate professor in the Department of Biochemistry of City University of Hong Kong, said that in theory, as long as bisphenol a 100% is converted into plastic structure in the process of manufacturing PC, it means that the product contains no bisphenol A at all, let alone released.

However, if a small amount of bisphenol A is not converted into the plastic structure of PC, it may be released into food or drink. Therefore, when using this kind of plastic container, we should be especially careful.

Extended data:

The convenience brought by plastic bottles is obvious, but the pollution they bring is often ignored. An article in the British "Guardian" wrote that it is estimated that by 20021year, the global consumption of plastic bottles will reach 500 billion a year, far exceeding the efficiency of recycling, and the natural environment such as seawater and coast is facing the harm of plastic pollution.

According to relevant statistics, the global consumption of plastic bottles reached 480 billion in 20 16, but less than half of them were recycled and only 7% were reused. Most of them are mixed with garbage and buried in the sea.

Plastic bottles buried underground will pollute soil and groundwater. Plastic bottles flowing into the ocean are bound to be eaten by some marine life, and eventually through the food chain cycle, let humans eat their own fruits. Therefore, it is urgent to control the pollution of plastic bottles, not only for our generation but also for future generations.

Recycling is a very good choice. Plastic bottles are mainly made of polyethylene or polypropylene and contain a variety of organic solvents. Most of the materials are recyclable, which lays a foundation for controlling the pollution of plastic bottles.

With the foundation, we must also lay a good "combination boxing."

First of all, it is necessary to carry out garbage sorting and recycling. Although the garbage sorting and recycling system has been popularized in various places, the effect is not obvious. Therefore, it is necessary to increase publicity and vigorously promote garbage sorting and recycling. This is not only conducive to the recycling of plastic bottles, but also conducive to the classification of other garbage.

Secondly, enterprises should bear the responsibility of recycling. Beverage, mineral water and other production enterprises use a large number of plastic bottles every year, but the responsibilities do not match. Enterprises should be urged to increase some measures to encourage recycling of plastic bottles in the sales process in order to improve the reuse rate of plastic bottles.

Third, encourage research and development of more plastic bottle recycling technologies. The high recycling cost is an important reason why many enterprises are discouraged from recycling plastic bottles. Therefore, the government should encourage and support the research and development of plastic bottle recycling technology through funds, taxes and other means, and use technology to reduce the recycling cost.

In addition, developing alternative products is also a way to go. Now many countries in the world are aware of the harm of plastic products, including plastic bottles, to the environment, and strongly support the research and development of products that can replace plastics. For example, British college students developed an edible film made of natural seaweed extract. Consumers can put water and drinks in a film and drink them together. This is a useful attempt.
