Market demand for environmentally friendly materials increases
As a new type of bio-based degradable material, the emergence of PLA material is undoubtedly an important step in responding to the country's green environmental protection policy and "dual carbon" goals. Polylactic acid is made from renewable resources such as corn, cassava, and straw. Its low-carbon green cycle characteristics make it a representative of environmentally friendly materials. In recent years, with the country's attention to "white pollution", degradable materials such as PLA have gradually been regarded as a "good prescription" to solve environmental problems.
In this context, young people who often drink milk tea are no strangers to the "PLA" words commonly seen on straws. As a disposable item, straws have greatly affected the sustainable development of the environment. The promotion of PLA materials is precisely to replace traditional petroleum-based straws, which is of great significance in reducing environmental pollution.
A solid step towards technological independence
In the industry, the production technology of polylactic acid has always been monopolized by a few foreign companies, and domestic development has been slow. The breakthrough of Wuxi Nanda marks the gradual strengthening of my country's independent production capacity in this field. Relying on the scientific research results of the team of Academician Zhang Quanxing of Nanda, the institute has achieved a major breakthrough in catalyst technology, and all major production equipment, processes and control software are developed domestically, breaking the dependence on foreign technology and realizing full localization from raw materials to production processes.
Diverse applications of polylactic acid
The strong application potential of polylactic acid lies not only in the production of disposable environmentally friendly materials, but also in many fields such as textiles, plastics, packaging, and agricultural films. Depending on the polymerization conditions, the properties of the produced PLA vary. Some high-purity polylactic acid is used for products that require higher strength, while low-purity polylactic acid is suitable for rapid degradation. This flexibility and diverse characteristics have enabled PLA to continue to improve its position in the field of sustainable development.
In the future, we can expect more green technology products to gradually replace traditional polluting materials and bring about a more environmentally friendly life. At the same time, with the help of these technological breakthroughs, my country's renewable resource efficiency will also achieve a qualitative leap in various fields.
