Because the main chain of the polymer containing benzene ring is relatively stable and high, many people think that the biodegradable plastic containing benzene ring cannot be degraded by microorganisms, but because of the biodegradable aromatic polymer, due to the special nature of its chemical structure, nature There are also microorganisms that can degrade benzene rings, so they can also be degraded by peribiotics, and the toxicity of the degraded products will not cause harm to the environment. The figure below shows the changes in organic carbon and its microorganisms (hyphae) during the degradation of PBAT.

The organic carbon of each structural unit of the PBAT chemical structure is decomposed by microorganisms in the soil, including filamentous fungi, etc., and new substances are formed. Studies have shown that organic carbon does not affect plants after degradation.

Sanle plastics is a biodegradable plastic bottle manufacturer and aim to deliver the eco-friendly plastic bottles all over the world. Here we studied about the degration situation of the PBAT material, and find out that they can be degrated completely in the nature. To learn more, please contact us.
