Recently, when you are hungry, you announced the acquisition of Baidu take-out. According to the China’s take-out big data released by Hungry, the current market user size has reached 600 million. In 2016, online take-out users accounted for 63.3% of the weekly consumption, which is as high as 63.3%. Far more than the frequency of white-collar workers cooking at home in the first and second tier cities.
The reason why the capital games of the big guys can cause so much attention is because the takeaway has changed our lives unconsciously.
According to the “2017 China Local O2O Industry Research Report†released by iResearch, in 2016, local living service O2O formed two models of home and store, and the overall transaction scale of the industry was close to 700 billion.
At the same time, the research report on China's online food and beverage market in the first half of 2017 predicted that the overall transaction volume of the take-away market in 2017 will reach 204.56 billion yuan, a growth rate of 23.1%.
Discard 200 million takeaway lunch boxes at least once a week
Recently, the takeaway giant Meituan announced that the number of orders on the day exceeded 12 million. The number of orders that are hungry is about to break through the 10 million mark. Together with other take-away brands, it is conservatively estimated that the takeaway brothers will send at least 30 million takeaways a day. .
According to this consumption method, at least 200 million takeaways per week fly through the streets of the country. This also means at least 200 million disposable packaging boxes and 200 million plastic bags, as well as 200 million disposable tableware.
Take-out garbage mainly includes plastic or foamed lunch boxes, plastic bags, disposable chopsticks, and the like.
The packaging boxes and packaging bags used in these packaged take-aways are mostly disposable plastic products, which are basically not reusable.
These plastic bags and disposable lunch boxes have an average usage time of less than one hour. When the takeaway brother delivers food to the consumer, these bags with various restaurant advertisements have already fulfilled its mission.
They are then thrown into the trash can, mixed with other types of garbage, and the plastic bag can enter the degradation process.
The complete degradation of each plastic bag takes at least 470 years, and about 8 million tons of plastic are dumped into the ocean each year.
China is the world's largest user of plastics, and its plastic dumping ranks first in the world, accounting for about one-third. According to the daily increase of 30 million, the use and dumping of Chinese plastic bags will continue to increase substantially.
Ecological pressure brought by take-away garbage
According to the calculation of 0.06 square meters per plastic bag for each single takeaway, the plastic bag used every day can cover 420,000 square meters, which is equivalent to 59 football fields, and can cover a West Lake in about 15 days.
200 million plastic garbage garbage every week can still be closed?
Since most of the discarded lunch boxes have not been cleaned, many of them have food residues, and it is not easy to recycle the lunch boxes. The recycling price of takeaway lunch boxes is usually two or three cents a kilogram, and 50 lunch boxes are still sold for less than 5 cents. Together with the cost of cleaning the lunch boxes, there is basically no profit. The recycling site is not waiting to be seen, and the takeaway lunch box can only be dumped together with other garbage.
Plastic waste cannot be recycled through clean channels, and can only be converted into white pollution and destroy the ecological environment.
Marine dumping is serious
The amount of plastic waste we dumped in the ocean is growing every year. At this rate, by 2050, the weight of plastic in the ocean will exceed the weight of the sea fish itself.
The plastic garbage in the ocean cannot be decomposed, purified, and eventually returned to our food chain invisibly.
Scientists refer to this substance as "plastic particles."
On October 29, 2015, the American authoritative popular science magazine Science American published a report on Chinese salt.
The report shows that polyethylene, polyethylene glycol, polyethylene, and cellophane and other plastics used in the production of plastic bottles have been found in the common salt of 15 brands purchased from all over China. Sea salt is most contaminated by plastic. There are more than 1,200 plastic particles per pound (453g). Although the plastic particles of salt mine salt are relatively low, they also reach 800 tablets.
Such plastic microbeads are generally less than 2 mm in diameter and are not easily visible to the naked eye. In the fish market in California and Indonesia, 1/4 of the fish's small intestine contains plastic particles. Although plastic particles are less likely to cause harm to human health, they should be alert to the risk of qualitative changes.
The “garbage siege†in all parts of the country
According to statistics, China produces hundreds of millions of tons of urban garbage every year, which makes many cities suffer from the pain of garbage.
From "Plastic Kingdom" to "Garbage Besieged City", Wang Jiuliang used images to tell people that on the edge of Beijing City, hundreds of thousands of scavengers are the main force of garbage sorting and recycling. Without their hard work, Beijing may have been The garbage is drowning.
These two documentaries are accompanied by pains and doubts, but the reality is that the phenomenon of garbage siege presented in the film exists in all major cities in China. The news about garbage sieges is frequently reported, and the large amount of take-away garbage and food produced every day. Residues contribute a lot to the formation of the garbage siege.
Who is paying for the white box of the meal box?
Takeaway is not a unique invention in China. How to deal with foreign takeaway garbage?
The lunch boxes used abroad are generally cartons or biodegradable materials. It is understood that in Japan, the recycling fee for the lunch box is borne by the consumer; in Europe and the United States, the processing fee is borne by the manufacturer.
In June 2000, Shanghai began to implement the “Interim Measures for the Management of Disposable Plastic Lunch Boxesâ€. The management department will charge 3 cents each for the production of disposable plastic lunch boxes as recycling treatment fees, but this system is implemented during the process. Not smooth, in May 2014, the method was abolished.
There is no doubt that the recycling of the lunch box requires cost, so the question of who pays the bill becomes the key. Since China does not have a corresponding subsidy mechanism for the recovery of renewable resources such as waste plastics, this has led to the unwillingness of all parties to bear this cost.
Another path that can be used for reference is to learn the Japanese model and do a good job of sorting garbage from the source.
I have to admit that our garbage classification awareness is weak, and the classified trash cans installed on the streets are ineffective. Most people will throw their garbage into a trash can. The garbage bins in many communities are not classified. The household garbage of the households are all piled up together, which makes the sorting in the later stage extremely difficult.
In addition, our waste sorting guidelines are not clear, and most people are confused about which wastes are renewable and which are not.
For the management of white pollution, take-out platforms and users should share the cost.
Some take-away platforms have begun to take the initiative to promote environmentally friendly lunch boxes. According to reports, outside the US group and hungry, it is working with scientific research institutions to develop degradable environmentally friendly lunch boxes.
Use safe, environmentally friendly, degradable green tableware to reduce the difficulty of recycling and degradation of take-away waste. Although rising costs may cut profits from take-out platforms and merchants, this is the price that the Internet must bear while reshaping people's lifestyles.
The cost of the lunch box is unlikely to be borne by the merchants and the platform. If the take-out platform really launches the green lunch box, the user will share the cost more or less. But this is also fair. After all, we have enjoyed the convenience of opening a mouthful of meals without going out of the house.
With the rapid developments in tunnel traffic infrastructure construction, engineers need a portable and real-time system to obtain the tunnel deformation during construction. An automatic and wireless real-time tunnel deformation monitoring system, which is based on laser and machine vision and can give early warnings for tunnel collapse accidents, is proposed. The proposed system uses a fixed laser beam as a monitoring reference. The image acquisition modules mounted on the measured points receive the laser spots and measure the tunnel accumulative deformation and instantaneous deformation velocity. Compensation methods are proposed to reduce measurement errors caused by laser beam feasibility, temperature, air refraction index, and wireless antenna attitude. The feasibility of the system is verified through tunnel tests.
