Effects of Biodegradable film on Soil

The biodegradable film can pass through composted and decomposed by the ocean, which is gradually obtained by society. According to composting, the biodegradable film is buried in the soil and decomposed by bacteria in the soil environment. However, the impact of these natural degradation processes on soil bacteria is unclear, and there is concern that the breakdown of the biodegradable film by bacteria will disrupt the soil bacterial community structure. Several studies have shown that biodegradable films lead to increased microbial biomass and enzyme activities in soil, increased soil fungal abundance, and altered soil microbial community structure, ultimately altering carbon cycling and storage in soil.

If the soil structure is changed, there will be almost no pressure on the subsequent soil cultivation, but it will have a significant impact on the soil, such as moisture and temperature. However, these biodegradable films do not exhibit ecotoxic effects, so they do not hurt the environment. In addition, the biodegradable process needs certain conditions and a period before it can be completely decomposed and returned to nature. Therefore, the biodegradable film in the market must achieve strict conditions to approve this certification.

As the concepts of environmental protection, energy saving, low carbon, emission reduction, and sustainable development are highly respected around the world, the research on biodegradable films will continue to increase. The transformation of the biodegradable film will become a research hotspot and research trend for soil membranes. In the future, research trends in this field will be diversified in many countries. Therefore, Kae Hwa also continued to develop biodegradable film, mainly using PBAT materials that are currently available in the market.
