Since the invention of plastics, it has been widely used in our life. A large number of non-degradable plastics not only bring great convenience to public life, but also cause serious pollution to the environment.
In addition, as the main raw material for plastic production is oil, which has cast a shadow on the energy crisis, the development of biodegradable materials to replace traditional plastics has become a trend.
According to the World Economic Forum in Davos in 2014 BBS forecast data, by 2050, the proportion of non-degradable micro-plastic particles in the ocean to fish will increase from 1:5 to 1:1, triggering an ecological crisis.
By 2050, oil used to produce plastics will account for 20% of crude oil production, triggering an energy crisis. Therefore, the development of biodegradable materials is an effective way to control white pollution and alleviate the energy crisis.
All countries in the world support the development of biodegradable plastics
From the domestic situation, in order to limit the use of non-degradable plastics and support the development of degradable plastics, the central and local governments have issued many policies.
In 2008, the State issued the Plastic Bag Limitation Order.
In 2011, the National Development and Reform Commission issued regulations to encourage the use of biodegradable materials, focusing on supporting the development of biodegradable materials.
In 2014, the National Development and Reform Commission established demonstration zones for the development and promotion of biodegradable products in Changchun, Wuhan, Tianjin and Shenzhen.
In 2015, the Ministry of Agriculture began to carry out biodegradable plastic film tests in 13 provinces and municipalities throughout the country, screening and promoting highly efficient biodegradable plastic films. Among them, Jilin promulgated the "Plastic Ban" to promote the use of PLA35 biodegradable materials in an all-round way.
In 2016, Jiangsu Province promulgated the Circular Economy Regulation, which prohibits the use of non-degradable shopping bags. Hebei Province promulgated the Circular Economy Regulation, which stipulates that the wholesale and retail places of commodities should sell and provide degradable plastic shopping bags.
In 2017, biodegradable materials were included in the 13th Five-Year Plan of material science and technology innovation.
From the perspective of a series of policies, China will further restrict the production of non-biodegradable plastics and continue to support the development of biodegradable materials to protect the environment.
Biodegradable plastics are widely used and have broad market prospects
Biodegradable plastics are mainly used in packaging, fiber, agriculture, medicine and other fields, among which packaging industry is the most widely used. According to BCCResearch data, the demand for biodegradable plastics is expected to reach 1386,000 tons in 2019, and the compound annual growth rate will exceed 15.7%.
Take PBAT as an example, its main market is plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware. China is a big consumer of plastic film. In 2017, China produced 14 million tons of plastic film, including 8.4 million tons of packaging film (60%) and 4.2 million tons of agricultural film (30%).
The potential market is estimated to be about 250,000 tons based on 2% of the total amount of alternative packaging/agricultural film. If the total amount of alternative packaging/agricultural film is estimated to be 5%, the potential market is about 630,000 tons. PBAT has broad market prospects. In the future, packaging is still the main market of biodegradable plastics PBAT. At the same time, with the development of new applications in automotive and electronic industries, the market demand for PBAT will grow rapidly.
From the global market of biodegradable materials, the main regional markets are Europe, North America and Asia-Pacific. Europe is in the leading position in demand and occupies the largest market.
In 2018, Europe accounted for about 36.8% of the global market for synthetic and biodegradable plastics, followed by North America. From 2011 to 2018, the Asia-Pacific market grew by an average of 25.7% annually, but China's market demand was relatively small.
In Europe, on October 24, 2017, the plenary session of the European Parliament voted to support biodegradable plastic films in the amendment of EU fertilizer regulations, with a potential market of about 100,000 tons. Shopping bags and other bio-based and biodegradable materials require about 60-70,000 tons.
As far as China's market is concerned, biodegradable materials rely on policy guidance and government encouragement and support in the short term because of their high cost and low-end application market. However, from the perspective of future prediction, biodegradable materials in China have great potential.
If 30% of China's ordinary shopping bags are biodegradable, the market potential is about 300 - 500,000 tons per year. The "Green Movement for Newbies" plans to replace 50% of traditional plastic bags with biodegradable plastic bags by 2020, creating a market of about 100,000 tons.
到2020年，农业薄膜产业将以生物降解塑料薄膜取代传统塑料薄膜的5%-10%，形成约20 -40万吨的市场。此外，随着城市垃圾分类处理和厨余垃圾堆肥处理的推广，如果30%的垃圾袋被生物降解垃圾袋替代，市场潜力约为6 -10万吨。
By 2020, the agricultural film industry will replace 5% to 10% of the traditional plastic film with biodegradable plastic film, forming a market of about 200-400,000 tons. In addition, with the promotion of urban garbage classification and kitchen waste composting, if 30% of garbage bags are replaced by biodegradable garbage bags, the market potential is about 6-100,000 tons.
At present, "white pollution" has become a key environmental issue of global concern. Various regulations have been promulgated at home and abroad to restrict or even prohibit the development of traditional plastics and to support the development of biodegradable plastics. Biodegradable plastics are widely used and have a broad market. The foreign market, especially the European market, is relatively mature, and the domestic market needs to be developed.
