Although China compostable packing bags are environmentally friendly and harmless, it does not mean that China compostable packing bags can be thrown away casually and discarded in the soil at will, and they can be naturally decomposed and turned into carbon dioxide and water. China compostable packing bags are still chemical products after all, and they also need to be degraded in a specific environment.
Let us first understand the China compostable packing bags, compostable raw materials mainly include PLA, PBAT and starch. Judging from the flow chart: the material is extracted from cornstarch as raw material, and then composted to become organic fertilizer. The whole process is not harmful to the environment. But all of this is based on the final composting treatment. China compostable packing bags need to be sent to specialized industrial composting sites for composting.

Industrial composting conditions: sufficient oxygen, high temperature above 50°C, humidity conditions and proper flora. Composting can speed up the process of degrading plastics to complete their decomposition.
But at present, the country has not done a good job in this aspect, and the industrial composting equipment is limited, and the number of composting plants is not large.
Environmental protection requirements are becoming increasingly stringent, and the application of China compostable packing bags is becoming more and more extensive, but the supporting facilities must be gradually improved. First of all, in terms of concept, it is necessary to change people's thinking. China compostable packing bags are not "rapidly degradable" in the full sense, nor can they degrade by themselves in the natural environment. Secondly, the construction of composting plants needs to be accelerated in order to keep up with the increasing production capacity.
