Competitiveness analysis and development prospect forecast of degradable plastics industry in 2020
Degradable plastics refer to a kind of plastics whose properties can meet the requirements of use, remain unchanged during the storage period, and can degrade harmless substances in the natural environment after use. Therefore, it is also called environmental degradable plastics. Now there are a variety of new plastics: photodegradation plastics, biodegradable plastics, light, oxidation / biodegradable plastics, carbon dioxide based biodegradable plastics, thermoplastic starch resin degradable plastics. China's degradable plastics have experienced 30 years of development. At present, China is the only country in the world that can produce all kinds of biodegradable plastics products. The product research of various varieties is also in the forefront of the world, and the production capacity has expanded rapidly in recent years.
Plastics not only bring convenience to people, but also bring great environmental pollution. Since the 1950s, the world has produced about 8.3 billion tons of plastics, of which 6.3 billion tons have become plastic waste. At present, more than 100 million tons of white garbage are still produced every year. As the raw material of plastic products polymer resin has strong stability, it takes hundreds of years to degrade in the natural environment. The degradation process not only takes up a lot of land resources, but also pollutes water and air. The problem of white garbage pollution has attracted the attention of many countries. Plastics can be divided into non degradable plastics and degradable plastics according to their degradation modes. Degradable plastics refer to the plastics whose properties can meet the use requirements and remain unchanged during the storage period, but can degrade the environmentally harmless substances in the natural environment after use, also known as environmentally degradable plastics. Non degradable plastics refer to plastics that cannot or are difficult to be degraded by microorganisms. They are usually degraded slowly in nature for hundreds of years. Degradable plastics have their advantages in performance, practicability, degradability and safety. In terms of performance, degradable plastics can reach or surpass the performance of traditional plastics in some specific fields; in terms of practicability, degradable plastics have similar application and sanitary properties with similar traditional plastics; in terms of degradability, degradable plastics can be degraded quickly in natural environment (specific microorganisms, temperature and humidity), and become easily environmental friendly In terms of safety, the substances produced or remained in the degradation process of degradable plastics are harmless to the environment and will not affect the survival of human beings and other organisms. At present, the biggest obstacle to replace traditional plastics is that the production cost of degradable plastics is higher than that of similar traditional plastics or recycled plastics. Therefore, degradable plastics have more alternative advantages in packaging, agricultural film and other application fields, such as short service time, difficult recovery and separation, low performance requirements and high impurity content requirements.
Recently, the national development and Reform Commission and the Ministry of ecological environment issued the opinions on Further Strengthening the control of plastic pollution, proposing to promote three main tasks in accordance with the idea of "banning one batch, substituting one batch, and standardizing one batch". Among them, "prohibition and restriction on one batch" includes "prohibition or restriction on the use of non degradable plastic bags, disposable plastic products, express plastic packaging, etc. step by step and in different fields". It can be seen from the policy that there is a huge market space for degradable plastics, while Tianzhuang environmental protection has always been favored by the market. 59% of the white pollution comes from the packaging and agricultural plastic products. The disposable and difficult recycling characteristics of this kind of plastic are not suitable for plastic recycling. Only degradable plastics can fundamentally solve the problem of white pollution. In 2018, the global demand for plastics will reach 359 million tons, including 144 million tons for packaging plastics. There is a huge space for the replacement market of degradable plastics. The global demand for biodegradable plastics is increasing rapidly. In 2014, the demand for biodegradable plastics is 1.3 million tons, which is expected to reach 3.22 million tons by 2020, with an average annual growth rate of 16.7%. Among them, Europe has the largest demand, accounting for 31%, North America and China account for 28% and 20% respectively. China is the only country in the world that can produce all kinds of biodegradable plastics products. In recent years, the production capacity has expanded rapidly. In 2018, the scale of China's biodegradable plastics industry was about 5.44 billion yuan, with a year-on-year increase of 21.1%. In 2018, the output reached 650000 tons, with a year-on-year increase of 10.2%, including 95000 tons of fully biodegradable plastics and 555000 tons of destructive biodegradable plastics. In the past two years, the number of foreign sales orders in China has shown a blowout growth. In 2018, the number of orders in China's Internet catering delivery market reached 10.96 billion, with a year-on-year growth of 96.8%. At the same time, it also brought the rapid increase of disposable tableware. The plastic packaging materials for a takeaway include plastic bags, plastic bowls, plastic spoons and plastic soup cups. At present, petroleum based polymer plastics such as polystyrene, polypropylene and polyvinyl chloride are basically used. According to the calculation, the weight of a single plastic bowl and plastic lunch box is about 40g-60g. According to the survey conducted by the environmental protection organization "natural University", each takeout consumes 3.27 lunch boxes on average, generating about 160g of plastic. According to the 11 billion takeout orders in 2018, the total consumption of disposable tableware plastic materials is about 1.76 million tons. Considering the strong growth in the number of takeout orders, the disposable plastic produced by takeout in the future The amount of cutlery will be huge. With the rapid increase in the use of disposable lunch boxes, this issue has attracted more and more attention. In June 2017, meituan takeout, China Cuisine Association, and China Environmental Protection Foundation jointly launched the green takeout industry convention (Green 10) with several catering takeaway brands, including the related content of "promoting the use of green tableware". In October 2017, the State Food and Drug Administration issued the food safety supervision and management measures for online catering services, which also specifically mentioned that the third-party platform providers of online catering services were encouraged to provide degradable food containers, tableware and packaging materials. The above-mentioned new measures will come into effect on January 1, 2018.
At present, the cost of biodegradable materials is high, which needs to be promoted by policies and enterprises. The takeout industry is similar to the express delivery industry and belongs to an oligopoly competitive industry. It is expected to make full use of the advantages of policies and platforms to promote biodegradable plastics for businesses. Based on the implementation schedule and intensity of the plastic ban policy in various provinces and cities, as well as the development history of overseas degradable plastics, we forecast the demand change of degradable plastics in China in the next 10 years. By 2025, it is estimated that the demand for degradable plastics in China will reach 2.38 million tons, and the market scale will reach 47.7 billion yuan; by 2030, the demand for degradable plastics in China will reach 4.28 million tons, and the market scale will reach 85.5 billion yuan. There is a huge market space for degradable plastics in China. With the promulgation of environmental protection law, the opinions of the CPC Central Committee and the State Council on accelerating the construction of ecological civilization, the outline of "healthy China 2030" planning, and the ecological environment protection plan, environmental pollution has been paid more and more attention by the society. As the main source of white pollution, biodegradable plastics will usher in the turning point of development In 2018-2023, China's biodegradable plastics market will break out in an all-round way. It is estimated that China's domestic consumption of biodegradable plastics will exceed 67000 tons in 2023.
Due to its more stable performance and lower recycling cost, degradable plastics have more alternative advantages in packaging, agricultural film and other application fields, which are difficult to be recycled and separated; while recycled plastics have more advantages in the application scenarios of living appliances, building materials, electrical appliances with long service time and easy classification and recycling because of its lower price and production cost Zhang. White pollution mainly comes from the packaging field, and degradable plastics have more space to play. With the promotion of policy and the reduction of cost, the market prospect of degradable plastics is broad in the future.
