How long can biodegradable plastic bags be completely degraded?
Based on my knowledge, the degradation time of biodegradable plastic bags is influenced by various factors, such as temperature, humidity, oxygen content, microbial content, etc. Therefore, the specific degradation time may vary depending on the environment.
Generally speaking, in environments with normal temperature, humidity, oxygen, and microorganisms, the degradation time of degradable plastic bags will be faster. For example, under experimental conditions, the degradation time of degradable plastic bags in artificially simulated soil environments typically ranges from a few months to a year.
However, in nature, under conditions such as composting that contain a large amount of organic matter, carbon, and other complex components, the degradation time of degradable plastic bags may be longer, sometimes taking several years or even longer to fully decompose.
Therefore, the degradation time of degradable plastic bags is not fixed and needs to be evaluated based on actual situations.
