In September 2020, China clearly stated the goal of "carbon peak" in 2030 and "carbon neutrality" in 2060. The "Double Carbon" strategy advocates a green, environmentally friendly, and low-carbon lifestyle. The Electronic Paper Industry Alliance based on this concept is located in the Baoshan Yangtze River Software Park. is widely used.
The reporter came to the e-paper industry alliance located in Baoshan Changjiang Software Park. The exhibition hall of more than 300 square meters showed us the application of e-paper in e-book reading, new retail, education, transportation, medical care, industry, civil aviation, logistics, office and other fields. wide application. It is understood that electronic paper is a kind of bistable display technology that does not emit light by itself, relies on ring light reflection imaging, and can permanently maintain images in an uncharged state. Its display effect is close to that of traditional paper.
Taking the 1.6-inch electronic price tag as an example, the carbon footprint of the whole life cycle is 0.1398 kg of carbon dioxide equivalent. only 2 button batteries are needed, it can be refreshed 3-5 times a day, and can be used continuously for more than 7 years. In 2021, 160 million sets of electronic paper price tags will be used globally, and more than 300 million sets will be used in 2022, an increase of nearly 100%.
Under the implementation of education informatization 2.0, it is required to construct user portraits based on students' knowledge mastery map, and support personalized, precise and intelligent adaptive learning. In the K12 education stage, one end for each person becomes inevitable. The smart electronic paper homework itself does not emit light and does not hurt the eyes. AI big data analysis is formed through the homework cloud system, which supports double reduction of homework time statistics. Students can master map statistics on homework knowledge points, and objective questions are automatically assigned to the teacher to reduce the burden. Stage paper 1.789 million tons/year (2.34 million tons of carbon dioxide equivalent/year). More than 100 schools across the country have participated in the three-year pilot operation (more than 20 in Shanghai). At present, it has entered the stage of city-level popularization.
Since 2019, more than 6,000 e-paper stop signs/posts have been built in the Puxi non-electric waiting hall, making it the largest application in the world. Compared with LCD liquid crystal products, the electricity bill can be saved by more than 20 million yuan in 3 years. In August 2022, Shanghai Aoma Technology and BSI (British National Standards Institute), a subsidiary of Juss Bus, adopted the ISO international carbon footprint standard and completed the world's first carbon neutral project for electronic bus stop signs (42.9 tons of carbon emissions, purchased through carbon sinks and achieve zero carbon emissions).
According to statistics from the China Post Bureau in 2021, there are 108.3 billion express parcels in China, and 50% of the cartons are discarded, which is a lot of waste. In the Chinese national standard "Express Recycling Box" that is being formulated, electronic paper sheets are included. On November 11, 2021, led by the Electronic Paper Industry Alliance, the "Common Management Requirements for Green Circular Packaging of Major Appliances" was officially established, which will stimulate leading brand enterprises in the major appliance industry, logistics and distribution companies, and recyclable packaging companies to jointly promote the smart recycling of major appliances Green packaging.
The Secretary-General of the Electronic Paper Industry Alliance said: "I hope that by building an ecological platform for the industry alliance, the upstream and downstream of the industrial chain will be aggregated to play the role of an industrial amplifier with 1+1 greater than 2, and a display base for the electronic paper industry chain will be formed in Baoshan. I hope more industrial ecology The leading enterprises gathered in Baoshan, helping Baoshan to build the main position of Shanghai Science and Technology Innovation Center.”
As of 2020, hundreds of millions of electronic paper display screens have been shipped, driving the output value of the upstream and downstream industries to exceed 100 billion yuan. It is reported that the E-Paper Industry Alliance is jointly initiated by E Ink, BOE, and Xingtai Technology. It is composed of well-known enterprises such as Lenovo, Ali, Tencent, Hisense, HKUST Xunfei, Hanshow, Zhikong, and Yangtze River Software Park, as well as related companies in the e-paper industry chain. , research units, and experts spontaneously formed. With the mission of replacing traditional paper, the Electronic Paper Industry Alliance actively promotes the innovative application of green, low-carbon, recyclable, and digital economy smart IoT, and earnestly implements the national development concept of "lucid waters and lush mountains are golden mountains and silver mountains".
