1. Introduction to the Project

1.1 Project background

1.1.1 Project introduction

Polylactic acid has good thermal stability, processing temperature of 170~230°C, good solvent resistance, and can be processed in a variety of ways, such as extrusion, spinning, biaxial stretching, injection blow molding. In addition to being biodegradable, products made of polylactic acid have good biocompatibility, gloss, transparency, hand feel and heat resistance.

Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials derived from renewable plant resources such as corn. Starch raw materials are saccharified to obtain glucose, and then fermented by glucose and certain strains to produce high-purity lactic acid, and then synthesized polylactic acid with a certain molecular weight through chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in nature after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to the protection of the environment, and is recognized as an environmentally friendly material.

1.1.2 Market prospect

(1) Plastic pollution hazards

With the development of the economy, consumption upgrading, and the rapid development of the express delivery industry and takeaway industries, plastics have become a necessity in our daily life, such as express packaging, takeaway packaging boxes, supermarket shopping bags, etc. In recent years, the consumption of plastics has been increasing, and the environmental pollution problem has become increasingly apparent, which has brought great harm to human health and the ecological environment. Currently, the main problem of environmental pollution is the decomposition of plastics, such as microplastics and chemical additives, many of which are known to be toxic and harmful to the health of humans and wildlife, as well as to ecosystems. The human body is susceptible to plastic contamination of water sources in several ways, which can lead to hormonal changes, developmental disorders, reproductive abnormalities, and cancer. Plastics are ingested through seafood, beverages, and even table salt; when plastics are suspended in the air, they are inhaled and penetrate the skin.

The treatment of plastic pollution should mainly start from four aspects: source reduction, recycling, substitution and cleanup, among which replacing traditional plastics with degradable plastics in the natural environment is an important part of the above treatment work. At present, countries around the world have introduced policies to encourage the use of degradable plastics, and China has also introduced a new version of the plastic ban in 2020 to support the promotion and use of degradable plastics.

According to incomplete statistics, at present, the European Union, North America, Japan, South Korea, Thailand, Pakistan and some countries in Africa have issued different degrees of plastic bans or plastic restrictions, and the data of some countries show that the use of disposable plastic products has declined. Countries around the world have accelerated plastic bans and restrictions.

(2) Application prospect of polylactic acid degradable materials

From the perspective of actual demand, with the support of the plastic restriction and plastic ban regulations of various national and regional governments, the actual global demand for degradable plastics has maintained a continuous growth trend. In terms of downstream applications, polylactic acid has been applied in many fields due to its unique biocompatibility and biodegradability, and the application scenarios are constantly expanding. At present, it has been widely used in food contact packaging and tableware, film bag packaging and other products and fields. For example, the agricultural mulch film made of polylactic acid can completely degrade and disappear after the crop is harvested, which will not reduce the moisture content and fertility of the soil, and can also exempt the additional labor and operation costs required to recycle the mulch film, which is the general trend of China's future plastic film development, and the future development space of the polylactic acid industry is huge.

In recent years, the market size of China's takeaway catering has developed rapidly, and the market size of China's takeaway industry was about 1,525.4 billion yuan in 2024, and it is expected to maintain a strong growth momentum in the next few years, and is expected to reach 1,956.7 billion yuan by 2027. Takeaway requires the consumption of a large number of plastic products, including plastic lunch boxes, plastic bowls, plastic soup spoons, plastic straws, etc. In addition, the “Opinions on Further Strengthening the Control of Plastic Pollution” issued by the state clearly mentions the orderly prohibition and restriction of the production, sale and use of non-degradable plastic bags and non-degradable disposable plastic tableware, and the active promotion of alternative products. It can be expected that the plastic products used in takeaway will be gradually replaced with degradable plastic products, so that the demand for polylactic acid will continue to increase.

Analysis of the market size of polylactic acid, from the perspective of the application field 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, applications such as catering utensils, fiber/non-woven fabrics, and 3D printing materials also provide new growth points for the polylactic acid market. As a biodegradable material, polylactic acid has a good market development prospect, especially driven by factors such as environmental awareness improvement, technological improvement and policy support, the polylactic acid market is expected to usher in more development opportunities.

1.1.3 Technical analysis

Polylactic acid production is based on lactic acid as raw material, and most of the traditional lactic acid fermentation with starchy raw materials. At present, the United States, France, Japan and other countries have developed the use of agricultural and sideline products as raw materials to ferment lactic acid to produce lactic acid, and then produce polylactic acid. The preparation of polylactic acid can be divided into the following three methods.

1. Direct polycondensation method

The polycondensation method is the direct condensation of lactic acid monomers, also known as one-step polymerization. In the presence of a dehydrating agent, the hydroxyl and carboxyl groups in the lactic acid molecule are dehydrated by heat and directly condensed into oligomers. A catalyst is added, the temperature continues to rise, and the low relative molecular weight polylactic acid polymerizes into a higher relative molecular weight polylactic acid.

2. Two-step method

Lactic acid is used to form cyclic dimeric lactide, which is then opened and polycondensed into polylactic acid. This technology is relatively mature, and the main process is that the raw materials are fermented by microorganisms to obtain lactic acid, and then after refining, dehydration oligomerization, high-temperature cracking, it is finally polymerized into polylactic acid.

3. Reaction extrusion to prepare high molecular weight polylactic acid

The combination of batch stirring reactor and twin-screw extruder was used to carry out continuous melt polymerization experiments. Polylactic acid with a molecular weight of 150,000 can be obtained by continuous melt polycondensation. A twin-screw extruder is used to further polycondense the low molar mass of lactic acid prepolymer on the extruder to prepare a higher molar mass of polylactic acid. When the reaction temperature is 150°C, the catalyst dosage is 0.5%, and the screw speed is 75 r/min, the molar mass of polylactic acid can be quickly and effectively improved by twin-screw reaction extrusion polycondensation, and the dispersion coefficient of the reaction extrusion product is reduced and the uniformity is improved. Through the comparison of DSC curves, it was found that the crystallinity of polylactic acid prepared by reactive extrusion polycondensation method was reduced, which was beneficial to improve the brittleness of polylactic acid materials during use.

The project partner company, Donghua Tianye (a subsidiary of Donghua Technology Holdings), is vigorously expanding the industrial chain of degradable materials, is developing the production process of polylactic acid (PLA), and has overcome the production technology of PLA lactide products.

The promulgation of this regulation has clarified the specific timetable of “plastic restriction and ban”, which has played a great role in promoting the application of polylactic acid products in China.

The introduction of policies such as “Opinions on Accelerating the Prevention and Control of Agricultural Mulch Film Pollution”, “14th Five-Year Plan” for the Development of Circular Economy”, “Standard Conditions for Agricultural Film Industry (2017) ”, and “Classification of Strategic Emerging Industries (2018) ” have also brought market demand to polylactic acid.
