Network optimization information:

To ensure the accuracy and reliability of product testing results, pay attention to factors that affect the degradation rate during product testing. Some substances will undergo biodegradation tests in the laboratory to obtain approval, but these results may not reflect real-world results, because various factors will change greatly in the real world. For example, a material can be tested for high biodegradability in a laboratory, but in a landfill, the degradation rate may not be high, because the landfill usually lacks the light, water, and microbial activity required to degrade the material. Therefore, standards must be formulated for degradable plastic products with environmental impact. The development and use of accurate standard test methods helps to ensure that all plastics in production and commercial use can be biodegraded in the natural environment.

In actual use, degradable plastics refer to materials that maintain mechanical strength after use and decompose into low-weight compounds and non-toxic by-products. The material is decomposed by microorganisms and is usually a water-insoluble polymer. This material can be obtained through chemical synthesis, microbial fermentation and chemical modification.
