There are really many people talking about environmentally friendly garbage bags. Different people have different requirements for environmentally friendly garbage bags: some believe that as long as good raw materials are used to produce garbage bags, it is environmentally friendly, and some believe that adding environmentally friendly materials to garbage bags is environmentally friendly. Yes, and some people think that as long as they see the relevant test report, garbage bags are environmentally friendly. Today, Science and Technology will discuss what kind of garbage bags are truly environmentally friendly.
“Environmentally friendly” plastic bags on the market mainly include these types: degradable plastic bags, biodegradable plastic bags, and compostable plastic bags.
Degradable plastic bag: The polymer in the plastic bag is partially or completely damaged due to ultraviolet radiation, oxidation corrosion, and biological corrosion. This means changes in properties such as fading, surface cracking and fragmentation.
Biodegradable plastic bags: The biochemical process in which the organic matter in the plastic bags is completely or partially converted into water and carbon dioxide, energy and new biomass under the action of microorganisms (bacteria and fungi).
Compostable plastic bags: Plastic bags can be biodegraded under the special conditions of high-temperature soil, and usually require industrial composting to achieve better degradation efficiency.
Only fully degradable garbage bags are truly environmentally friendly garbage bags. They are made of carbon materials extracted from plants such as corn and sugarcane. They can be degraded into water and carbon dioxide without polluting the air and soil. Since photodegradation and water degradation need to be degraded in a specific environment, plastic bags in the market are generally “biodegradable.”
At present, the cost of degradable garbage bags is 3-5 times that of ordinary garbage bags, and the cost of use is much higher than that of ordinary garbage bags. The market share is still at a relatively small stage and there is not much circulation. We can choose to buy Read the instructions carefully and make a choice if you have a goal.
