The raw material of ordinary garbage bags is PE, no matter how good the raw material is, it is not degradable. According to the traditional methods of burying or incineration, it will cause pollution, so it is not “environmental protection” in the true sense.
Some garbage bags add a degradable “starch machine” to the raw materials, but they can only degrade locally, dispersing the garbage bags into “flakes”, and the broken garbage bags still cannot be degraded, so it is also Not really “environmental protection”.
Only fully degradable garbage bags are truly environmentally friendly garbage bags. They degrade into water and carbon dioxide without polluting the air and soil. Since photodegradation and water degradation need to be degraded in a specific environment, “biodegradation” is relatively common in the market.
At present, the cost of degradable garbage bags is 3-5 times that of ordinary garbage bags, and the use cost is much higher than that of ordinary garbage bags. There are not many users who actively choose degradable garbage bags.
The market share of biodegradable garbage bags is still very small, and there are not many circulations. We must be careful when choosing to buy.
