As an effective agricultural auxiliary material, agricultural film is widely used to increase crop yields, improve soil quality and water resources management. Currently, the global demand for sustainable agriculture is becoming increasingly urgent, and biodegradable plastics have become one of the focuses of attention. As one of the representative materials, PBAT provides a new solution for achieving sustainable agriculture.

1. Agricultural film overview

• Types and uses of agricultural films

Agricultural films include covering films, greenhouse films, mulch films and other types, which are widely used in many aspects such as planting, covering and protection. Various films play a unique role in agricultural production, but they also bring environmental problems, especially the refractory nature of traditional plastic films.

• Challenges of traditional agricultural films

With the large-scale application of traditional agricultural films, problems such as plastic waste and resource waste have gradually become prominent. This has prompted people to actively search for biodegradable materials to reduce the negative impact of agricultural films on the environment.

• Introduction and advantages of PBAT

PBAT is a biodegradable plastic with superior degradability and environmental protection properties. Compared with traditional plastics, the application of PBAT in agricultural films is regarded as a disruptive technology that is expected to solve many problems faced by traditional agricultural films.

2. Benefits of sustainable agriculture

• Reduce plastic pollution

The widespread application of biodegradable plastics can help slow down the environmental pollution of traditional plastics and reduce plastic waste in farmland and waters.

• Soil protection and ecological balance

By using degradable agricultural films, we protect the soil structure, promote soil ecological balance, and reduce the negative impact of agricultural activities on the ecosystem.

• Improvement of agricultural production efficiency

Sustainable agricultural practices not only help protect the environment, but also improve agricultural production efficiency, reduce production costs, and increase farmers' income.

3. Features and advantages of PBAT

• Definition and properties of PBAT

PBAT is a degradable polyester plastic with good degradability, mechanical properties and thermal properties. These properties make PBAT an ideal choice for agricultural films.

• Degradability and environmental protection characteristics

PBAT has high biodegradability and can be quickly decomposed in the natural environment, reducing pollution to soil and water resources. Its environmentally friendly features have injected new vitality into the agricultural film field.

• Application of bio-based plastics in agricultural films

In addition to PBAT, there are other bio-based plastics used in agricultural films. What these materials have in common is that they are degradable and environmentally friendly, providing multiple options for the sustainable development of the agricultural film industry.

4. Application of PBAT in agricultural films

• Farmland mulching film

In an agricultural area in China, farmers use PBAT farmland mulching film to increase soil temperature and promote the growth of early-maturing crops. Compared with traditional films, PBAT films not only effectively increase soil temperature during use, but can also quickly degrade after the end of the life cycle, reducing soil pollution. This application not only increases farmland yields but also reduces negative environmental impacts.

• Greenhouse film

In some modern greenhouse farms in the Netherlands, PBAT is widely used in the manufacture of greenhouse films. This film not only has the insulation and light-blocking functions of traditional films, but also naturally decomposes after the season. In this way, farmers can maintain high yields in vegetable production without worrying about the environmental impact on the land.

• Land conservation and water management

In some agricultural fields in Australia, farmers use PBAT mulching to prevent soil erosion. Compared with traditional mulch films, PBAT mulch films can not only cover the land for a long time to protect the soil, but also can quickly degrade into substances harmless to the land after the end of its service life. This approach improves land use efficiency while minimizing pressure on water resources.

5. Find a PBAT supplier

Dawn Group has completed the construction of a 60,000-ton/year plant, and successfully tested it in March 2023. The products are exported to Italy, Germany, the Netherlands, India, Vietnam, Australia, South Korea, Central America and other countries and regions, and the product quality has been recognized by customers.

Dawn Group's degradable plastic PBAT has applied for and accepted 9 national invention patents, and has obtained degradable certification and food contact certification issued by international authoritative organizations such as EU DIN CERTCO, US BPI, and Australian ABA.
