Since the outbreak of the epidemic in Hong Kong two years ago, citizens are trapped in urban areas wearing masks every day. Many people choose to go to the suburbs to explore different hiking spots in the suburbs, stretch their muscles and relax their bodies.
However, in addition to being overcrowded, the quiet suburbs also leave behind a lot of rubbish causing sanitation problems.
Tai Lam Chung Reservoir, known as "Hong Kong's Thousand Islands Lake", has become one of the popular hiking spots in the past two years. To enjoy the beautiful scenery, you must first pass through So Kwun Wat Village.
It is a pity that the residents living in So Kwun Wat Village have suffered from tourists throwing rubbish indiscriminately since the outbreak of the epidemic. The garbage bins and recycling bins around So Kwun Wat Village are full every week.
Two years ago, the village chief's daughter, who was in the first grade of secondary school, had to spontaneously clean up with her family every week. Otherwise, it would cause hygiene problems and the huge amount of garbage would block the access roads.
Therefore, she and three classmates came up with the concept of automatic garbage sorting, and successfully developed an AI smart recycling bin.
Put the recyclables on the surface of the box, and the AI system will automatically identify and put them in the appropriate sorting compartment, and will automatically notify the recycler when it overflows.
This invention won the third place in the science competition held by the Youth Association last year, and was recommended by the association for the "Korea Science and Engineering Competition" (KSEF).
The students in the team have a deep experience and want to tell the public that "every piece of waste has a value in its existence."

Visitors to "Thousand Island Lake" must pass through So Kwun Wat Village to leave garbage to the villagers
Li Tongqian, who is currently studying at the Wanjun Boqiu College in Tin Shui Wai, said that when there was no hiking boom in Hong Kong two years ago, "there are enough trash cans nearby."
Since the outbreak of the epidemic, Hong Kong citizens have been keen to go to the countryside. In recent years, the general public likes to check in at the Tai Lam Chung Reservoir, which is known as "Hong Kong's Thousand Island Lake". If you want to overlook the whole beautiful scenery, one of the paths needs to pass through the sweeper where she lives. Guan Wat Village.
Before the epidemic, there weren't too many mountain hikers, so my Ditiao Village would scare myself, but everyone in Qiandao Lake would travel to take pictures.

It's a pity that there are a lot of tourists every week, and at the same time, a lot of garbage is left. The garbage bins and three-color recycling bins are also full. Tourists throw garbage indiscriminately, polluting the environment not only increases the risk of the epidemic, but also makes the recyclable waste not properly sorted. Recycle.
She has always been in the habit of sorting and recycling waste. As the daughter of the village chief, she and the villagers can't bear the harsh environment. They have to clean up and recycle their waste with several villagers every week, and then take the waste out of the large black garbage collection box near the road.
Hikers rarely go to the public toilets, and most of them throw them away (the garbage bins at the nearest intersection) immediately after going out of the mountain, because everyone is so lazy.

Inspired by street garbage bins and three-color recycling bins in housing estates
Every time Li Qiantong cleaned the So Kwun Wat Village, she would complain when she went back to school that the repetitive garbage sorting work was tiring.
And her classmate Yuan Dibei also felt that the garbage bins on the street are easily full on weekdays, and the three-color recycling bins are only placed in the corner of the housing estate or in an inconspicuous place.
When Ling got a cold, Teacher Zhang, who teaches mathematics and science, invited four students to design a collection station with an AI artificial intelligence system that can automatically classify the "waste".
In addition to Li Qiantong and Yuan Xibei, the production team also joined the third-level Guan Zixuan and Huang Junxi, who were responsible for coding and programming.
The "waste" station is an AI smart recycling bin. The system will automatically identify the waste and put it into the appropriate sorting bin, and will automatically notify the recycler when it overflows.

The top design of the improved school garbage can, the latest third generation can receive 50 liters of garbage
Yuan Xibei said that during this research and development process, the four students had different opinions and insistence.
But in the end, everyone is willing to try different things and tolerate each other for the sake of product results. Even though classes were suspended last year due to the epidemic, students often met online until the evening to continuously improve the design.
Yuen said that the original design used cardboard as the base of the collection box, and also wanted to design only one collection box to handle the amount of waste in a housing estate.
Now in the latest version, they have found the school's trash can, improved the top design by themselves, and added devices such as lenses and electronic boards. When the waste is placed on the top of the recycling bin, the system will automatically identify and automatically push the garbage to the corresponding recycling category: aluminum Cans, plastic bottles, paper-wrapped beverages, and general waste will not touch the recycling bin with your hands during the process.
At present, their latest third-generation "waste" station can carry 40 to 50 liters of garbage, and it only takes 1 to 2 seconds to identify the waste each time.
Vice Principal Feng (second from right) and Teacher Zhang (third from right) of Wanjun Boqiu College said that they were glad that the students had built up their self-confidence in the competition.
I also appreciate the persistence and seriousness of the students in the product.

The standard degree of automatic identification of recyclables has reached 70%
Yuan Xibei said that before participating in the science competition with Li Qiantong, they had no clue about coding and computer programs.
However, during the design process, the two of them served as art design and product explanation positions, while Guan Zixuan and Huang Junxi continued to research and produce programming codes.
Guan Zixuan said that since the AI system needs a lot of data in advance, the more sufficient the data, the more accurately the AI system can execute the relevant instructions.
The third-generation lens installed on the top of the recycling bin can automatically identify the recyclables with a standard degree of 70%.
Guan Zixuan pointed out that behind this result, the entire group of students spent a lot of time taking photos of each recycled object. Each recycled object requires at least 400 photos, with different angles and shielding objects, and then transmitted to the intelligent system for identify.

"Village Chief's Girl" Li Qiantong: I most hope that hikers will take away their own garbage
Yuan Xibei said with a smile that before participating in the Korean competition, they will persevere and continue to improve the design, hoping that one day they can be used in the school first.
"Village Chief Girl" Li Qiantong said that she most hoped that hikers would know how to take their own garbage away when they left, or realize that waste has value after recycling through design.
Feng, the vice president of Wanjun Boqiu College, said that the school has a special in-depth learning week, which provides different activities for students who are interested in technology design; also encourages students to participate in different competitions during the 6 years of school, and believes that learning is the most important thing. confidence.
When she and Teacher Zhang participated in the science competition, they noticed that they had always had low self-confidence or were not good at expressing themselves, but as they prepared for the competition, they gradually built up their self-confidence, even when designing products or reporting. When faced with difficulties, we can focus on persevering and find the path that interests us.
