The Conventional Problem of Biodegradable Takeaway Bags
The recent phase of the rapid development of the food and beverage takeaway industry, the major takeaway platform competition is very fierce, which also gives consumers to provide more convenient life. But a takeaway will produce a lot of disposable tableware and bags, for the environment and human health has brought a great negative impact on the regular issue of biodegradable takeaway bags we take a look at the contents of this.
1, whether only composting treatment
This is not necessarily, can be degraded in composting conditions, can also be degraded under other conditions, but also in the natural environment, such as soil and seawater and other conditions of biodegradation, but the specific and the chemical structure of the plastic, the product formula and other degradation environment is related, so that only in the composting treatment is not right, in the above conditions can be degraded.
2, in the anaerobic digestion device is not able to completely degrade
The main reason why degraded takeaway bags can be degraded by microorganisms is because their chemical structure is different from that of traditional plastics, so they can be degraded by microorganisms. Most of the current explainer materials can be degraded under the anaerobic digestion device.
3. Is it completely degradable in the soil
Under uncontrollable conditions such as natural soil, temperature, moisture and microorganisms, the conditions of the composting process in controllable conditions are relatively uncontrollable. Most degradable plastics are currently biodegradable under field soil conditions, such as PBAT, PHA, PCL, PBS, etc. They can be completely degraded within 5 months of being buried in soil under normal climatic conditions and will not affect plants; PLA materials degrade more slowly and take a long time, but can be completely degraded in about half a year after mixing with PBAT and other materials.
