Will Biodegradable Film & Bag release harmful substances or pollutants during degradation? What are the potential effects of these substances on the environment and organisms?

Biodegradable Film & Bag generally do not release harmful substances or pollutants during degradation. Such products are designed to be converted into water, carbon dioxide and other harmless small molecules through biodegradation in the natural environment. This degradation process is mainly participated by microorganisms such as bacteria, which decompose organic pollutants into smaller molecules through biooxidation or other biological transformations.
Specifically, studies on products such as biodegradable mulch (reference article 3) show that their effects on the abundance, activity and community structure of soil microorganisms are positive. This further supports the safety of biodegradable materials in the natural environment.
However, it should be noted that although biodegradable pollutants will eventually be completely decomposed into harmless substances, some biodegradable pollutants themselves may be toxic, such as olefins, naphthalene, anthracene, phenoxyacetic acid herbicides, etc. However, the use of such substances in biodegradable films and bags is not common.
As for the potential impact of these substances on the environment and organisms, it mainly depends on their specific types and degree of degradation. If they can be completely degraded into harmless substances, the impact on the environment and organisms will be minimal. However, if the degradation is incomplete or these substances are toxic in themselves, they may have negative effects on the environment and organisms, such as water hypoxia, ecological balance disruption, etc. (Reference article 2).
In general, biodegradable films and bags will try to avoid using toxic or harmful substances during the design and production process to ensure that they do not release harmful substances or pollutants during the degradation process. However, consumers still need to pay attention to the product description and certification information when choosing such products to ensure their safety and environmental protection.
