Nearly 90% of college students support garbage classification
half of the pairs of fuzzy classification criteria
"Support garbage sorting, add a chicken drumstick for dinner." On the second day of Shanghai's garbage sorting, Wang Juntong from the School of Environmental Science and Engineering of Tongji University sent a circle of friends who can recycle books and paper shells that he does not normally use. The items were put into the recycling vending machine set up in the school and received a reward of 27.9 yuan.
Recalling his experience a year ago, Wang Juntong said that although his major was related to the environment, but at the beginning of the implementation of the garbage classification policy, the relevant classification common sense still gave him a "down horse power". In addition to the need to independently learn common knowledge of classification, the garbage station at the door of the bedroom with a clear classification and a small scale also affects Wang Juntong and the students around him.
Starting May 1, 2020, the new version of the "Beijing Municipal Waste Management Regulations" was officially implemented. Up to now, 46 key cities across the country have implemented garbage classification regulations. In the future, garbage classification will be implemented globally. Under the trend of garbage classification, how do college students view garbage classification? What problems did they encounter in the implementation of garbage classification? What questions do you want to be answered?
Recently, the school youth media launched a questionnaire survey for 900 college students across the country. The survey results show that 87.4% of college students support garbage classification, hoping to implement garbage classification measures in their cities.
Nearly nine students support garbage but only half could correctly identify
Although the garbage classification regulations have been implemented locally for nearly a year, the sophomore Fan Mengke, who lives in Xi'an, still has insufficient grasp of the garbage classification standards. "It will hesitate when sorting, and judgment is based on intuition."
A survey conducted by the school youth media found that 43.9% of the college students consciously sorted out garbage when they dealt with it. However, only 4.6% fully grasped the garbage classification standards, 42.3% could distinguish most of them, 43.4% said that they could partially distinguish, and 9.7% said that they could not distinguish basically.
In the general knowledge survey on garbage classification initiated by the school youth media, "crossed socks", "clam shells", "cat litter" and "expired chocolate" are all topics that are of more interest to college students, but college students who can correctly classify are not many. "This is the most difficult questionnaire I have filled in." Xu Meng, a freshman student at Shanxi Agricultural University, said after filling in the questionnaire.
At the beginning of the implementation of the garbage classification regulations, there are different opinions on garbage classification in various places. The popular science articles and paragraphs circulating on the Internet are dazzling. When eating dumplings once, Xu Jingwen's family, who lives in Jiading District of Shanghai, was very entangled-I don't know if the dumplings were wet or dry garbage. After some searching, they found that although Zongye is a kind of perishable biomass waste, it can eventually become soil fertilizer and organic medium after treatment, but in the actual disposal process, the texture of Zongye is relatively hard and tough, and a lot of Entering the disposal equipment may damage the equipment and affect the normal operation of the equipment, so zongye should be treated as dry garbage.
He Jinjing, a doctoral tutor at the School of Environmental Science and Engineering at Tongji University, introduced that under the current standards, waste can be roughly divided into four categories: hazardous waste, recyclable waste, kitchen waste and other waste. "The names are different in different places, but the classification methods are roughly the same." Taking kitchen waste as an example, "wet garbage in Shanghai, kitchen waste in Beijing, and biodegradable garbage or rotten garbage in other places."
Although some small programs and popular science articles have subdivided many types of garbage, they will still face some problems when they are implemented into life. A survey conducted by the school youth media found that 59.0% of the college students surveyed thought it was troublesome to deal with garbage, 68.7% of the college students' communities did not have a corresponding trash bin configuration, 63.0% of the college students thought that the people around them did not have a high sense of garbage classification, and 57.9% of the college students thought It takes time to adapt to garbage classification.
The first problem encountered by Wu Tingwei of Tongji University is that he frequently misses the launch time. The garbage station has a fixed time for throwing in garbage. If you catch up with a class and place a bucket of recyclable garbage in the dormitory, you can only barely "stick" for another day. After the implementation of garbage classification, the point of takeaway also has "worries about the future." If food is left, treat it separately from the packaging. Some packages can be disposed of as recyclables after cleaning, but almost no one will wash the meal box.
Zhang Tiantian, a sophomore who lives in Shanghai, once felt uncomfortable. Garbage collection not only needs to be fixed on time, but also has manual supervision. Sometimes the supervisor also opens the garbage bag to check, so that he is worried that his privacy will be violated.
Health and safety issues have also caused Zhang Tiantian's concerns. Every time you put in wet garbage, you need to open the plastic bag, throw the garbage into the wet garbage can, and then throw the plastic bag into the dry garbage can. "This is not only troublesome, but sometimes your hands may get dirty." Fortunately, the community A faucet was installed next to the garbage throwing point, and the hands could be washed in time after the garbage was poured, dispelling Zhang Tiantian's concerns.
47.2% of college students join the promotion team spontaneously
Although they have not yet fully adapted to garbage classification, university students are very careful about this matter. The survey conducted by the school youth media found that 86.1% of college students will consciously learn the knowledge of garbage classification, 44.6% of college students can strictly implement the garbage classification standards, and 47.2% of college students actively pass relevant knowledge to those around them.
Many college students can realize the necessity of garbage classification for environmental protection. Li Aimin, a doctoral tutor at the School of Environment, Dalian University of Technology, told the China Youth Daily and China Youth Daily that after implementing garbage classification, garbage that was originally difficult to recycle can be recycled through different treatment methods. "For example, kitchen waste can be made into organic fertilizer, methane, etc." The classification and treatment of hazardous waste avoids the surface water pollution and soil pollution that may be caused by the mixed treatment of waste.
"Implementing garbage classification is a good way to protect the environment. From the perspective of society, industry and industry, garbage classification is very good for terminal treatment." Wu Tingwei, who was born in the class, not only fully supports the implementation of garbage classification, but also participated in Tongji University has developed a waste classification plan in multiple areas including teaching areas.
"The effectiveness of college students in implementing garbage classification regulations should be more obvious than other groups." Li Aimin believes that college students should actively participate in the promotion and promotion of garbage classification while doing their own garbage classification.
Wu Yilei, a sophomore who lives in Zhangjiagang City, looks forward to the implementation of the local garbage classification regulations. Before the implementation of garbage classification officially started, her community had already launched publicity in the form of mobile phone text messages, push messages, scrolling of advertising walls, and popular science manuals. "A QR code is set next to the trash can. After each trash is correctly classified, residents can get the corresponding'red envelope' reward." This model makes Wu Yilei feel fresh.
"I think when everyone is doing this, it would be weird if only you don't classify it well." Once, when the other residents of the community saw the garbage thrown wrong by the garbage station, the always shy Xu Jingwen couldn't help but remind other side. For Wang Juntong, although his hometown has not officially started to implement the garbage classification regulations, he will still remind his friends to sort them out when throwing garbage.
In Wu Tingwei's view, college students should strengthen their self-consciousness in participating in garbage classification. Not only do they do garbage classification themselves, but they can also participate in the promotion and promotion of knowledge about garbage classification. "Let more people understand the process, significance and impact of garbage classification through scientific lectures and other forms. At the same time, you can observe more, think more, and promptly feed back to the relevant functional departments after problems are found to promote the construction and operation of the garbage classification system."
Yan Yuechen, a third-year graduate student at East China Normal University, put a small trash can on the dormitory table to collect wet garbage, and the original trash can was used to hold dry garbage. "I also found a cardboard box to collect recyclable garbage." She put the garbage classification query interface on the most easy-to-click location of the mobile phone. "Before discarding, confirm which waste bin each waste should be thrown into."
"The garbage room will also post some sorting methods, and the uncle who collects the garbage will also check the reminder in the garbage room." Yan Yuechen said, "Most students can voluntarily put in the garbage correctly."
There has been a rumors on the Internet: if you can't drink milk tea, the liquid must be poured into the sewer, pearls should be thrown into the wet trash can, and milk tea cups should be thrown into the dry trash can. Yan Yuechen really encountered this situation. Because most of the garbage cans on the roadside only collect garbage and recyclable garbage, she took a cup of undrinked milk tea along the way, and took the bus, subway, walking, and returned to the dormitory before throwing it away.
Expert suggestion: Do a good job of garbage classification from the consumer link
How to deal with uneatable steamed buns in areas where there is no wet garbage collection bin? The answer given by He Pinjing is: "Eat!" The students laughed at the answer.
In He Pinjing's view, "waste sorting should not only start from the abandonment link, but also from the consumption link and even the production link."
After finishing all the meals ordered, the milk tea and beverages in the cup are all consumed. Starting from the source of consumption to reduce the generation of garbage, especially the production of wet garbage, is He Pinjing's recommendation to college students. He also made suggestions to the relevant departments of Tongji University to provide small amounts of food specifically for some girls. "In the context of garbage classification, we should pay more attention to'do not produce garbage that should not be generated'."
"Through waste classification, food safety is also guaranteed. To divert food waste generated in public consumption places such as restaurants and canteens, the first thing is to solve the problem of gutter oil, which can avoid the rest of the table and then return to the table. In addition, avoid Food waste generated by public consumption is used to feed pigs to avoid the appearance of'garbage pigs.'"
Wu Yilei bluntly said that when she was living in Shanghai, she more and more did not want to order takeaway. The tedious sorting process annoyed her, "If you take out the takeaway, you still need to pour it out the same. Sorting, and even the fruits you need to eat, need to be subdivided." She therefore made less takeouts, and did not produce much. A lot of unnecessary garbage.
In addition, in Li Aimin's view, the garbage classification method should be adapted to local conditions. "It is necessary to classify garbage according to the actual local conditions. Cities of different sizes should make local regulations and formulate relevant regulations separately."
He Pinjing gave an example, "In our concept, glass bottles have recycling value. However, because glass bottles are heavy, large, and low in value, transportation and storage costs are very high. First-tier cities have high population density, shortage of land resources, and land value. High and high labor costs. In this case, the use of similar low-value recyclables is more difficult. The classification of recyclables and hazardous waste is probably the'back end' determines the'front end'."
In He Pinjing's view, waste sorting is a routine task, not an emergency task, and its sustainability needs to be valued. At the same time, he emphasized that in the face of garbage classification, college students should not only join it with practical actions, but also have a more scientific understanding and understanding of garbage classification, so as to make garbage classification stable and far-reaching.
