Plastic bags are divided into two categories, one is biodegradable shopping bags, which is an environmentally friendly shopping bag that will not cause any pollution or harm to the environment; the other is non-degradable shopping bags, which are ordinary shopping bags. Since non-degradable plastic bags cause a lot of harm to the environment, people now prefer to use degradable shopping bags. So who knows, what materials are biodegradable shopping bags made of?
Raw materials for biodegradable shopping bags
Degradable plastic bags are also called biodegradable shopping bags. They are made of materials extracted from plants such as plant starch and corn flour. These raw materials will not cause any harm to the human body and the environment.
The use of degradable shopping bags can be disposed of by landfill. It only takes a period of time for the shopping bags to be degraded into biological particles and then absorbed by the soil. Degradable plastic bags not only will not have any impact on the environment, but can also be used as fertilizers for plants and crops to promote plant growth.
Therefore, the use of degradable shopping bags is now popular, and the use of non-degradable shopping bags is slowly decreasing. Non-degradable shopping bags will cause great harm to human health and the ecological environment.
The dangers of non-degradable shopping bags
The opposite of degradable shopping bags is non-degradable shopping bags. In fact, ordinary shopping bags can also be degraded, but it has been degraded for a very long time, as long as two hundred years. What’s more, the amount of plastic bags used in human society is so large now. If non-degradable plastic bags are used again, the ecological environment of the earth will become worse and worse.
People don’t have a good recycling method for shopping bag waste, either incinerate or landfill. No matter which method is used to dispose of non-degradable shopping bags, it will have an impact on the environment. For example, incineration will emit an unpleasant smell and produce a large amount of black ash; if it is disposed of in landfill, it will take hundreds of years for the earth to decompose plastic bags.
Comparing degradable plastic bags with non-degradable shopping bags, degradable plastic bags are more environmentally friendly.
