Biodegradable kitchen garbage bags
Release time:
Dec 12,2024
The principle of biodegradable plastic bags is mainly based on biodegradation technology, which can be summarized as follows:
1, material selection: biodegradable plastic bags use biodegradable substrates and add natural materials such as starch and plant fibers. The introduction of these additives makes the plastic bags less stable and thus easier to degrade in the natural environment.
2, the degradation process: in natural conditions such as light and heat, these added natural materials can promote biodegradation of plastic bags. Specifically, the degradation process is carried out through microbial action, hydrolysis, oxidation, etc., to break down the polymer molecules into small molecules, such as carbon dioxide, water and organic matter and other natural substances.
3, degradation conditions: the degradation of degradable plastic bags need to meet certain environmental conditions. For example, the degradation effect is better when the temperature is usually in the range of 60-80 and the humidity is 60-80%. In addition, the participation of microorganisms is also an important factor in the degradation process, generally through the bag into the organic waste compost for degradation.
4, degradation effect: compared with ordinary plastic bags, biodegradable plastic bags in the degradation process of the substances produced will not cause pollution to the environment. They can degrade into water, carbon dioxide and soil fertility substances, which are beneficial to the environment.
