The cheapest degradable polymer today is Polybutylene adipate terephthalate (PBAT)

Polybutylene adipate terephthalate (PBAT) is a type of degradable polymer that has gained attention in recent years due to its low cost and environmental benefits. It is considered one of the cheapest degradable polymers available today. PBAT is made from the combination of adipic acid, terephthalic acid, and butanediol.

PBAT is part of a group of polymers called biodegradable polymers, which are designed to degrade under specific conditions. These polymers offer a more sustainable alternative to traditional plastics, which can take hundreds of years to decompose. PBAT, in particular, has been found to degrade within a relatively short period of time, making it an ideal choice for various applications.

One of the main advantages of PBAT is its low production cost. Compared to other degradable polymers on the market, PBAT is more affordable, making it a popular choice for manufacturers and businesses looking to switch to more sustainable packaging options. The low cost of PBAT also helps to make eco-friendly products more accessible to a wider range of consumers, as the price point is more competitive compared to other alternatives.

In addition to its affordability, PBAT offers several environmental benefits. When PBAT breaks down, it transforms into carbon dioxide, water, and biomass, which can easily be absorbed by the environment. This process is known as complete biodegradation. As a result, PBAT does not contribute to the accumulation of plastic waste in landfills or oceans, reducing the negative impact of plastic pollution.

PBAT also has excellent mechanical properties, making it a versatile material for various applications. It can be molded into different shapes and used in the production of films, fibers, and injection-molded products. Its flexibility and durability make it suitable for applications such as packaging films, agricultural films, and disposable food containers.

Another advantage of PBAT is its compatibility with other degradable polymers, such as polylactic acid (PLA) and starch-based polymers. These materials can be combined to create blends that enhance the overall performance and degradability of the product. This compatibility opens up opportunities for the development of even more sustainable packaging solutions in the future.

Despite its many advantages, PBAT does have some limitations. It requires specific conditions, such as a composting environment, to fully degrade. If PBAT ends up in a traditional landfill where these conditions are not met, it may take longer to decompose. Additionally, the production process of PBAT still relies on fossil fuel-based resources, although efforts are being made to develop more sustainable alternatives.

In conclusion, Polybutylene adipate terephthalate (PBAT) is currently recognized as the cheapest degradable polymer available today. Its low cost and environmental benefits make it an attractive option for businesses and consumers looking to reduce their environmental impact. PBAT's affordability and compatibility with other degradable polymers also contribute to its market advantage. While there are still challenges to overcome, PBAT's potential to replace traditional plastics and reduce plastic waste cannot be overlooked.
