The goal of innovation is to focus on social life and solve problems.
"Beijing Xuanwu Science and Technology museum teacher Bishing said."
Not long ago, her two students Chen, Ma Zi after the investigation to make recommendations, the life of waste plastic compressed into pieces, promote classification and recycling. Chen, Ma Zi are junior high school students. In the spare time, they randomly to two supermarkets for 7 days of follow-up, found that the supermarket cashier's charge for the use of plastic bags is not small. For example, in Beijing, a supermarket set up 10 cashier, in the peak period of 1 hours, the average checkout of 35 orders per checkout, of which about 60% of consumers choose to buy a fee of plastic bags, the use of about 28.
Combined with the supermarket business hours, the number of supermarkets in Beijing, etc., students estimate the amount of plastic bags used by supermarkets to tens of billions of dollars each year. The huge use of plastic bags and their environmental hazards make students eager to find solutions.
However, they exchanged with the sanitation workers and some community recycling station staff to find that, in addition to plastic bottles, plastic bags and other life plastic waste because of fragmented and value is not high, the community recycling station is generally not recycled. In order to promote the classification and recovery of plastic bags, students developed the convenience waste plastic compression recycling device, and put forward the establishment of WeChat public number promotion incentive mechanism. They designed the waste plastic compression recycling device, the fluffy plastic waste in the compressed bucket into pieces, forming a ' plastic cake ', easy to recycle.
This device is small in size, easy to operate and suitable for home use.
In order to promote the use and promotion of environmental knowledge such as plastic reduction, students also recommend the development of the corresponding WeChat public number or mobile app, for everyone to set up a green points account. Of course, these programs are not perfect, the integral incentive system needs to be further improved, the actual recovery dilemma also needs to be broken. Ma Zi, for example, had been rejected for selling his own ' plastic cake ' to the community's recycling staff. He and his father Ma Xudong persuasion, from the dangers of plastic waste, talking about the need for sorting collection and processing, only to let the other party nod the recovery.
Ma Xudong that if we want to improve the economic benefits of recycling ' plastic cake ', we need more participation from the social subjects. At present, the students ' suggestions have been affirmed by Beijing Xicheng District Management Committee.
The two sides are embarking on a pilot in a district in Xicheng district. ' The more we make sense of the project, the more the children are aware of the environment and our parents are very educated. Ma Xudong said that he was affected by the children, more attention to the topic of plastic waste. This year back home in Shandong, is catching up with the flooding, some in the past were randomly buried in the field of abandoned plastic film shed, was flooded out, the stench. Therefore, the study of plastic waste is necessary.
' Bishing, who has been guiding students to carry out research on science and technology innovation, said that the research on environmental issues was ' particularly popular ' in the Youth Science and technology innovation competition in recent years. It does not stop at the past appeals and propaganda levels, but rather carries out more in-depth investigations and proposes more targeted measures and approaches.
