Development prospects of polylactic acid

Polylactic acid (PLA), as a new type of biodegradable material, has received widespread attention and application worldwide in recent years. The characteristics of the polyester polymer obtained by polymerizing lactic acid as the main raw material make it an environmentally friendly material choice.

With the increasing global emphasis on environmental protection and sustainable development, polylactic acid has shown broad market development potential in multiple fields. Especially in major economies such as China, the European Union, and the United States, the support for biobased materials continues to increase, providing policy guarantees for the development of biodegradable materials such as polylactic acid. For example, China's 14th Five Year Plan clearly sets out the goals of green and low-carbon development and ecological civilization construction, while the European Union's "European Green Agreement" and multiple environmental initiatives in the United States emphasize reducing plastic use and promoting the development of bio based materials. These policies are not limited to restricting the use of plastics, but also directly promote the expansion of the polylactic acid market through subsidies, tax incentives, and other means, making the development environment of the polylactic acid industry more favorable and providing clear development directions for enterprises.

In China, the market demand for polylactic acid reached 400000 tons in 2024, demonstrating its wide application and market demand in multiple fields. The polylactic acid market is showing a significant growth trend.

With the global attention to plastic pollution and the implementation of restrictions on disposable plastic products by multiple governments, polylactic acid, as an alternative to environmentally friendly materials, has rapidly increased in market size with the growth of the domestic food delivery market. With the trend of "replacing non degradable plastics with biodegradable materials", it continues to penetrate and develop into other fields where plastic materials are widely used.

Especially in the fields of packaging, disposable tableware, agricultural film, textiles, and medical supplies, the application of polylactic acid is gradually expanding. This indicates that the upstream raw material chain and downstream terminal market of polylactic acid have been fully connected, and the construction of an independent and controllable full industry chain has been completed, forming a "dual circulation" pattern with the polylactic acid industry chain abroad.

From the perspective of the application fields of polylactic acid, packaging materials are currently the largest consumer area, accounting for more than 65% of the total consumption. With the improvement of environmental awareness and the requirements of sustainable development, the application of polylactic acid in the packaging field is expected to further expand. At the same time, the application fields of catering utensils, fiber non-woven fabrics, 3D printing materials, etc. have also provided new growth points for the polylactic acid market.

Technological innovation is an important driving force for the development of the polylactic acid market. In recent years, by optimizing fermentation efficiency, improving polymerization processes, and diversifying raw materials, the production cost of polylactic acid has been reduced and its performance has been significantly improved. For example, using non grain crops such as corn stover and cassava waste as raw materials not only reduces dependence on food resources, but also broadens the sources of raw materials and reduces raw material costs. Meanwhile, through modification technology, the performance of polylactic acid materials in terms of heat resistance and toughness has been optimized, expanding their possibilities in high-end application fields. These technological advancements have lowered the terminal selling price of polylactic acid products and improved market competitiveness.
