Can biodegradable plastic polymers be converted into organic fertilizer?

Biodegradable plastic polymers can indeed be converted into organic fertilizers under certain conditions. This transformation process mainly relies on the decomposition of microorganisms, which break down organic matter in plastics into nutrients needed by the soil, such as nitrogen, phosphorus, potassium, etc., thus becoming organic fertilizers that plants can absorb and utilize.
Specifically, the main raw material for biodegradable plastics is bio starch, such as starchy foods like potatoes, corn, sweet potatoes, etc. Its production process consumes less energy and has low carbon emissions. Under the action of microorganisms, these biodegradable plastics can be completely degraded within a certain period of time (such as 90 days) and converted into organic fertilizers. This degradation process not only reduces the pollution of plastic waste to the environment, but also promotes ecological cycling and soil fertility improvement.
In addition, some studies have shown that bioplastics such as isosorbide based polycarbonate can be converted into nitrogen rich fertilizers such as urea under mild conditions through specific environmentally friendly processes. These degradation products can be directly used for plant growth, promoting healthy growth and development of plants.
In summary, biodegradable plastic polymers can indeed be converted into organic fertilizers under the action of microorganisms or specific environmental protection processes, providing nutrients to the soil, promoting plant growth, and promoting the healthy development of ecological cycles.
