Where is the difference in the "plastic reduction" of express takeaway?

  Where is the difference in the "plastic reduction" of express takeaway?

  The survey shows that China’s express delivery industry generates about 1.80 million tons of plastic waste every year. At the same time, food delivery is also the "hardest hit area" of plastic packaging, often "bag in bag". The "white waste" brought by express delivery has become a regulatory pain point.

  —————

  "Now the express delivery is piled up like a mountain, and half of the packaging is plastic." On November 12, Liu Shan (a pseudonym), a courier brother in Fengtai, Beijing, was worried about the resulting plastic waste pollution while running around for the seemingly endless express delivery.

  The rapid development of online shopping has brought further prosperity to the express delivery industry. On November 11, on the day of the shopping carnival, with 675 million pieces of express delivery, there were 675 million express packages.

  Zhang Deyuan, deputy director of the Research Office of the National Development and Reform Commission’s Institute of Macroeconomics and System Reform, said in an interview with a reporter from China Youth Daily and China Youth Network that the total number of express deliveries this year is expected to reach 80 billion, of which about 20% are packed in plastic bags. The "white waste" brought by online shopping has become a pain point for the supervision of the "plastic restriction order".

  Where is the difficulty in implementing the "plastic restriction order"? According to a survey conducted by the official Weibo of China Youth Daily, 59.7% of respondents preferred "changing public habits", 16.8% of respondents believed that "it is difficult to develop and promote new materials", 12.7% of respondents chose "shopping costs increase", and 10.7% of respondents said that "new fields are difficult to supervise".

  "Compared to cartons, plastic bags at 0.3 yuan each are cheaper"

  Zhu Wen (a pseudonym), the brother of Beijing Express, said that among the more than 200 express deliveries he delivered on November 11, more than 100 were packaged in plastic, mainly some clothing, quilts, shoes, etc.

  The reporter visited and found that the use of plastic packaging in the outer packaging of express deliveries delivered by many couriers accounted for 30% to 50%. Some express deliveries using carton packaging also place plastic fillers in the boxes to ensure the safety of goods transportation, and most of them are sealed with tape outside the boxes.

  When the courier arrives in the hands of consumers, it often goes through multiple processes. In order to prevent damage, some merchants will choose to pack multiple layers or even over-pack before sending the courier. Most of these packaging materials are purchased nearby or at a low price. Search an e-commerce platform, 100 35 × 45cm courier packaging bags are 14.2 yuan, and in some stores a packaging bag is as low as 0.039 yuan.

  In addition to express delivery, takeaway is also the "hardest hit area" of plastic packaging, and "bag in bag" situations often occur. According to the reporter’s observation, consumers order a rice noodle on the takeaway platform, and the powder and soup are packed in two plastic boxes separately. In order to prevent spillage, some merchants also wrap a layer of plastic wrap on the soup box, put it in a separate plastic bag, and then put everything in a large plastic bag.

  Some couriers give preference to plastic bags. Zhu Wen said that when sending, he hardly uses cartons, and probably uses more than 10 bags a day to pack for consumers. On the one hand, plastic bags are portable, and on the other hand, they are based on cost considerations. For example, for a 12 yuan courier, he can get 2 yuan service fee, of which the packaging fee needs to be paid by himself. "Compared with cartons, plastic bags are generally cheaper at 0.3 yuan each."

  "Plastic reduction" has a long way to go. According to the statistics of the Plastics Recycling Professional Committee of the China Plastics Association, our country uses about 3 billion plastic bags every day. As of 2019, the annual use of plastic bags exceeds 4 million tons. Another survey shows that China’s express delivery industry generates about 1.80 million tons of plastic waste every year.

  Where is the difficulty of "plastic reduction" in the field of e-commerce?

  Since the implementation of the "plastic restriction order" in 2008, "plastic reduction" has been running for 11 years. In recent years, as emerging business forms, e-commerce, takeaway and other fields have once become "blank areas" of the "plastic restriction order".

  On January 19 this year, the "Opinions on Further Strengthening the Control of Plastic Pollution" (hereinafter referred to as the "Opinions"), known as the upgraded "Plastic Limit Order", was released, and the takeaway and e-commerce fields were officially included in the scope of the "Plastic Limit Order". The opinion also clearly states that by the end of 2022, postal express outlets in Beijing, Shanghai, Jiangsu and other provinces and cities will first ban the use of non-degradable plastic packaging bags, disposable plastic woven bags, etc., to reduce the use of non-degradable plastic tape. By the end of 2025, postal express outlets across the country will be covered.

  In contrast to the huge amount of use, the collection rate of plastic bags is very low. On November 11 last year, the "Research Report on the Characteristics and Management of China’s Express Packaging Waste" jointly released by environmental protection organizations Greenpeace pointed out that in 2018, our country’s express delivery industry consumed a total of 851,800 tons of plastic packaging materials. Due to the difficulty of recycling plastic express packaging waste, high regeneration costs and low regeneration profits, about 99% of our country’s express packaging waste plastics (mass ratio) were mixed into domestic waste.

  Consumers rarely pay directly for express packaging, which affects the "plastic reduction" in the field of express delivery. Some netizens said that most of the time online shopping is free shipping, compared with supermarket shopping, the feeling of using plastic bags is not obvious, and they rarely pay attention to plastic waste in the e-commerce field.

  "The difficulty is that it is too scattered." Zhang Deyuan said that compared with ordinary supermarkets, the plastic packaging users in the e-commerce field are mostly small merchants. This group is large in number, scattered in main body, difficult to supervise and expensive to enforce.

  At present, the alternative product Research & Development production of plastic packaging is still not mature enough, and the circulation efficiency of domestic express packaging is not high. Zhang Deyuan takes degradable plastic bags as an example. The cycle of domestic express packaging from procurement, warehousing to circulation is about 30 days, which is a certain gap compared with foreign countries. For example, Amazon’s logistics efficiency is about 13.5 days. Long storage time of degradable plastic bags may lead to performance degradation and affect the use effect.

  Some netizens expressed that they wanted to do their part to reduce white pollution, but had to use plastic bags in the absence of suitable alternatives.

  At the end of last year, an online poll conducted by China Youth Daily showed that 86.6% of respondents felt that there was a waste of plastic bags in the e-commerce sector. 53.0% of respondents said they were willing to pay a certain amount for e-commerce to use reusable environmentally friendly packaging.

  Press the "acceleration button" for "plastic reduction" in many places.

  Faced with the big problem of "white pollution", various places have continued to make efforts on "plastic reduction". So far, more than 20 provinces have issued an upgraded version of the "plastic restriction order", pressing the "acceleration button" for "plastic reduction".

  Among them, six major industries such as food delivery and e-commerce have become the key "plastic reduction" objects of Beijing’s new version of the "plastic restriction order". On November 10, the "Beijing Plastic Pollution Control Action Plan (2020-2025) (exposure draft) " released by Beijing pointed out that by the end of this year, the city’s postal express and e-commerce distribution outlets will have a "slimming tape" packaging ratio of 90%. By the end of 2022, the city’s postal express outlets will ban the use of non-degradable plastic packaging bags, woven bags, etc. By the end of 2025, the city’s postal express outlets will ban the use of non-degradable plastic tape, and the responsibility will be implemented to specific units. This is also known as the "strictest plastic restriction order" by netizens.

  The "plastic reduction" in the field of e-commerce is a systematic project that requires platforms, merchants, and consumers to work together to create a green logistics system from the production, procurement, use, and recycling of plastic packaging.

  "Platform companies should be leaders in the control of plastic pollution." Zhang Deyuan believes that platform companies in the fields of e-commerce, express delivery, and takeaway should strengthen the management of merchants settled on the platform, formulate alternative implementation plans for reducing the amount of disposable plastic products, and implement "green merchant leadership plans" and "green packaging points activities" to encourage and guide merchants to take the initiative to reduce the use of disposable plastic packaging. The postal express industry should increase the use of green packaging and recyclable packaging. Operating merchants should be "executors" of green consumption patterns.

  At the same time, the research and development of alternative products will usher in new opportunities. Zhang Deyuan suggested that express delivery companies and packaging material production and development companies should strengthen innovation. At present, some companies are developing degradable plastic bags.

  On the consumer side, you can consider adopting a separate pricing and charging strategy. Zhang Deyuan said that consumers spend money and have a clear sense of use, which can indirectly enhance consumers’ environmental awareness. If plastic packaging is used, it should be classified for subsequent disposal and resource utilization.

  In addition, Zhang Deyuan also suggested that while enjoying the convenience brought by modern business models, consumers should continuously raise their awareness of environmental protection and minimize the use of disposable plastic utensils when ordering takeout and online shopping.

Ignite the "fire" of winter tourism

Source: [Ningxia Daily]

This winter, Yinchuan focused on emerging consumption hotspots, new consumption formats and trendy consumption scenes, and created five characteristic themes, 66 winter tourism projects and 112 sub-activities according to local conditions, presenting new products, new formats, new scenes, new ways of playing and new concessions of Yinchuan’s winter cultural tourism in multiple dimensions, and giving full play to the promotion of winter tourism marketing to the cultural tourism market.

Offering tourists a "big meal" of cultural tourism with rich cultural flavor and many new ways to play, so that tourists can experience the different winter in magical Ningxia in one stop. It must be said that the relevant departments have really made great efforts in tourism promotion. When it comes to visiting Ningxia, most people think that the best time period is the warmer weather season, and winter is the off-season of tourism. In fact, tourism has no off-season market, only off-season ideas. Seasons have never been the key factor that restricts the development of tourism. The key is whether the seasons can make a different feeling. Even if winter is not the most beautiful season in the traditional sense of Ningxia, as long as it is done with characteristics, it can ignite the "fire" of off-season tourism and give tourists a different experience.

To "break the ice" in the off-season, thoughts must be "thawed" first. Pursuing the "difference" of winter tourism is rooted in the change of thinking mode and working mode. Continue to explore the characteristic culture, enrich the tourism format, gather the tourist popularity, improve the industrial chain, carefully study what are their own characteristics and advantages, and then, with the confidence of winning and effective measures, promote the winter tourism market to flourish, which will surely make more tourists feel the unique winter scenery, come to Ningxia and fall in love with Ningxia.

Warriors Clippers reached a 3-for-1 deal! George teamed up with Curry! Paul returned to Los Angeles.

The Warriors Clippers reached a three-for-one deal, and George teamed up with Curry Paul to return to Los Angeles. With the deepening of Hugh Secchi, many teams have completed the reinforcement of their lineup. For the Golden State Warriors, their lineup is not perfect enough.

I have to admit that Chris Paul still has some trading value on the court, and many players played in his series for the Suns last season, and Booker is very grateful to Paul.

He said, in fact, when I was young, I learned to play like Paul, but I never had the opportunity to join hands with him. After joining hands with him, I also made up for my previous organizational deficiencies, and he will become one of the most important teachers in my basketball career. Paul himself must be very happy to have such praise.

According to saxophone, the management of Golden State Warriors is currently in contact with the management of Clippers, and they seem to want Paul George very much. The Los Angeles Clippers also think they need a mature point guard, so the Warriors may exchange Chris Paul for Paul George. What do you think of this deal?

Brief introduction of Artificial Intelligence (AI)

The development history of Artificial Intelligence (AI) can be traced back to 1950s. The following are the main stages of the development history of AI:

  1. Logical reasoning and problem solving (1950s-early 1960s): The early AI system was based on symbolic logic, and solved problems through logical reasoning of facts and rules. However, this method has limitations, and it is difficult to deal with a large number of uncertain and fuzzy information.
  2. Machine learning and pattern recognition (1960s-1980s): The research of AI began to turn to machine learning and pattern recognition. Machine learning is a method to learn and optimize algorithms by training data, while pattern recognition is a method to realize intelligence by identifying and classifying patterns. These methods have been widely used in image recognition, speech recognition and natural language processing.
  3. Expert system and knowledge representation (1980s-1990s): AI research began to pay attention to expert system and knowledge representation. Expert system is an intelligent system based on expert knowledge and inference rules, which can simulate the decision-making process of human experts. Knowledge representation is a method to organize knowledge and information into a form that can be processed by computer, and it is an important foundation to realize AI.
  4. Statistical learning and deep learning (1990s-2010s): With the continuous development of computer hardware and algorithms, AI research began to pay attention to statistical learning and deep learning. Statistical learning is a machine learning method based on statistical model and data analysis, which can handle a large number of data and complex nonlinear relationships. Deep learning is a machine learning method based on neural network, which can handle more complex and high-dimensional data.
  5. Self-learning and multi-modal AI(2010 to present): AI system is gradually realizing the ability of self-learning and self-optimization, and can continuously improve its own model and algorithm according to feedback and data. Multi-modal AI is an AI technology that can handle a variety of data types and perceptual information, including images, voices, texts, etc., and can realize more comprehensive and intelligent human-computer interaction.

Important events:

  • In 1956, the concept of artificial intelligence was put forward at Dartmouth Conference, which marked the birth of AI.
  • In 1962, Arthur Samuel developed a self-learning program, which was an early application of machine learning.
  • In 1969, Marvin Minsky and Seymour Papert published Perceptrons, which revealed the limitations of single-layer neural networks and promoted the development of neural networks.
  • In 1975, John Holland developed genetic algorithm, which is an optimization algorithm that imitates the process of biological evolution.
  • In 1981, Japan launched the first commercial robot WABOT-1.
  • In 1997, IBM’s deep blue supercomputer defeated Kasparov, the world champion of chess, indicating that computers can surpass human intelligence in some fields.
  • In 2011, IBM’s Watson artificial intelligence system defeated human players in the program "Dangerous Edge".
  • In 2016, AlphaGo defeated Li Shishi, the world champion in the Go competition, marking an important step in the application of artificial intelligence in complex games.
  • In 2018, the GPT-2 model developed by OpenAI made a major breakthrough in the field of natural language processing, which can generate high-quality natural language texts.

The latest development trend:

  1. Self-learning: AI system is gradually realizing the ability of self-learning and self-optimization, and can continuously improve its own model and algorithm according to feedback and data.
  2. Deep learning: Deep learning is a machine learning method based on neural network, which can handle a large number of data and complex nonlinear relationships, and is one of the main trends of current AI development.
  3. Artificial intelligence chip: Artificial intelligence chip is a chip specially designed for AI application, which can realize efficient calculation and data processing and is an important technical support for AI popularization and application.
  4. Multi-modal AI: Multi-modal AI is an AI technology that can handle a variety of data types and perceptual information, including images, voices, texts, etc., and can realize more comprehensive and intelligent human-computer interaction.
  5. AI and Internet of Things: The combination of AI and Internet of Things can realize more intelligent and efficient automatic production and management, including intelligent energy, intelligent transportation, smart home and other fields.
  6. AI Ethics and Law: With the continuous development and application of AI technology, AI ethics and legal issues have attracted more and more attention, including privacy protection, data security, and responsibility distribution.
