Under the limitation of plastic vents, ecological intelligence creates new opportunities for the development of the plastic industry?


In recent years, environmental issues have undoubtedly become a hot topic in the process of economic development. Especially after the "double carbon" policy, green sustainability has become a Weather vane for the long-term development of various industries. The layout of the industry around the main line of "carbon neutrality" is rapidly expanding. Following the popularity of new energy vehicles and photovoltaic industries by capital, the development of biodegradable plastics and ecological plastics to reduce the large amount of carbon dioxide generated during plastic production and incineration has become the focus of achieving "carbon reduction" in the consumer end.
According to data from the National Bureau of Statistics, China's plastic product production has increased from 58.306 million tons in 2010 to 80.04 million tons in 2021, maintaining a stable growth trend. While providing convenience for life, plastic products have also become the main culprit of environmental pollution, and white pollution such as Microplastics has gradually returned to the table. At the same time, the dual pressures of sustainable economic development and environmental protection have deepened people's demand for biodegradable materials, which also points the way for the transformation and upgrading of the traditional plastic industry.

Plastic restriction leads the ecological cycle, and the industry develops towards low-carbon direction
With the rapid development of industries such as express delivery and food delivery, the use of plastic products as important packaging materials has also increased exponentially. While driving the rapid development of the plastic industry, the treatment of plastic waste and the "white" pollution caused by improper treatment have become urgent problems that need to be solved in various regions.
According to statistics, out of a total of 9 billion tons of plastic products produced worldwide, only 9% are recycled, 12% are burned, and the remaining 79% are in landfills or flowing into the natural environment. The huge amount of use and waste is not only a waste of land resources, but also has an impact on soil quality, aggravating river pollution, farmland pollution and marine Plastic pollution.
In order to solve this problem, since 2020, the National Development and Reform Commission, the Ministry of Ecological Environment and other ministries and commissions have successively issued several policy documents related to Plastic pollution control, such as the Opinions on Further Strengthening Plastic pollution Control, the Notice on Solid Promotion of Plastic pollution Control, to prohibit or restrict non degradable disposable plastic packaging.
However, for plastic restriction, the key word is not "prohibit" but "replace", which means not completely "prohibit" the use of plastic, but to reduce the use of plastic products to a certain extent and scope, or replace non degradable materials with ecologically degradable and other materials, and replace disposable plastic with reusable plastic.
As a kind of green ecological and environmental protection material, eco degradable plastic is different from ordinary plastic. It shortens the degradation cycle of ordinary polyolefin plastic from more than 300 years to 2 to 3 years through eco plastic technology, and the degradation products are non-toxic and harmless, do not produce Microplastics, and can be directly returned to the ecosystem, solving the secondary pollution of plastic products to the environment from the source. With the gradual implementation of plastic restriction policies, the market size of degradable plastics has seen significant growth, especially in industries such as express packaging, takeout, and hotels, where demand growth continues to rise. Degradable plastics have ushered in new development opportunities.
From the development of the industry in the past five years, the average growth rate of consumption of eco-degradable plastics in China is around 20%. In 2019, due to production restrictions, the domestic consumption of eco-degradable plastics was about 260000 tons, which is basically consistent with production. At this growth rate, it is expected that the demand for biodegradable plastics will exceed 650000 tons in 2024.
"Turn white into green" ecological plastics help low Carbon cycle
In January 2019, the "Shandong Science and Technology Think Tank Forum and the First White Pollution Prevention and Ecological Plastic Development Forum" hosted by Qilu University of Technology and the "the Belt and Road" International Think Tank of the Chinese Academy of Social Sciences was held in Jinan, Shandong Province. The forum aims to accelerate the development of the ecological economic system by exploring typical cases in the prevention and control of white pollution, innovative ecological technologies, and new forms and models of green industry development. In addition, the forum also focuses on the research and promotion of ecological plastics, which is of great significance for promoting the further development of the ecological plastic industry in Shandong.
As a major agricultural province in China, Shandong has always played a leading role in the production and use of agricultural plastic products. In addition, in recent years, the province has promoted and protected Vegetable farming in a large area and encouraged vegetable exports. Therefore, in addition to Zibo, Shouguang, Linyi and other key areas where agricultural film is used, there are also areas where agricultural film consumption is concentrated, such as Yantai and Laiyang.
At the same time, the increasingly serious "white pollution" in farmland has quickly attracted industry attention to the development and application of degradable plastic film replacement technology. Therefore, Shandong has also cultivated a group of high-quality enterprises related to degradable plastics. Among them, in terms of ecological plastic technology, Shandong Tianzhuang Environmental Protection Technology Co., Ltd. added self-developed EBP degradation masterbatch in the production process of ordinary polyethylene products. Without changing the use performance of the original plastic products, it accelerated the transformation into water, carbon dioxide and Soil organic matter through light or thermal oxidation and environmental microbial action, and returned to the ecosystem to achieve degradation.
As a local enterprise growing up in Shandong, Tianzhuang Environmental Protection relies on a mature technical team and has successfully developed a complete series of ecological plastic products, including covering packaging, agriculture, and other ecological plastic products, mainly based on ecological plastic bags and ecological plastic mulch, after more than ten years of scientific research and research. With the experimental demonstration and application promotion of ecological plastic technology nationwide, ecological plastic film has been applied to over 6 million acres, and 1.5 billion ecological plastic bags have been exported.
With the rapid development of technology, technological means have also become an important path to promote the green development of the plastic industry. In December 2022, Qingdao Huicheng Environmental Protection Technology Group Co., Ltd. proposed the chemical recovery "trans phase cracking" technology at the first Eco plastic Low Carbon cycle Industry Development Forum, that is, the conversion of low value plastics into chemical raw materials, triene triphenyl, gradually replacing incineration and landfill, and replacing petroleum resources with garbage, which can not only effectively control Plastic pollution, but also achieve efficient hydrocarbon utilization and chemical cycle process cleaning. In addition, Shandong Senna Plastic Industry Co., Ltd. is also accelerating the production of biodegradable plastic tableware in promoting the use of biodegradable materials to replace traditional plastic production. Currently, it has reached an annual production capacity of 2 million pieces.
As a major plastic production city in China, Rizhao is speeding up the transformation and upgrading of the degradable plastic industry; According to statistics, there are more than 800 plastic product manufacturers in Rizhao, with an average daily output of more than 3000 tons. In order to seize the prospects of degradable plastics, the local government has also created an industry university research platform to assist in the green transformation and upgrading of the plastic industry.
From the perspective of industry development in recent years, circular economy is an important development direction for the plastic industry and also the upgrading and transformation direction for Shandong plastic enterprises. In the future, the Shandong plastic industry will also promote industrial green circulation through technological research and development and technological means, helping the industrial economy and ecological environment to develop simultaneously.
