Nowadays, degradable plastic bags are widely used in supermarket shopping bags, and some takeaway packaging bags are also using degradable plastic bags. When promoting, businesses will say that the use of degradable plastic bags can reduce the use of ordinary plastic bags and reduce environmental pollution.

How many days does it take for a degradable plastic bag to degrade? About 180 days, compared with the 300-year degradation cycle of ordinary plastic bags, it is very friendly. But can all the biodegradable plastic bags we see in the market really be degraded? The answer is that basically none of them can be completely degraded.

At present, the materials used in degradable plastic bags mainly include PLA (polylactic acid) and PBAT (copolymer of butylene adipate and butylene terephthalate). Some are mixed with other ingredients, that is, if they enter the composting process, they can become fragments in the soil, rather than decomposing completely.

We will see that the ingredients on the biodegradable plastic bags, the label on the drink bag of a fast food restaurant, says that it can be recycled or composted, and the labels on most supermarket and takeaway plastic bags indicate that It is recommended to recycle.

We know that most of the plastic bags are not reused and go into the recyclable garbage, which is recycled by the factory. If biodegradable bags are recycled together with ordinary plastic bags, it does not reflect the value of degradability, and because of the high processing cost, it does not realize its environmental friendly value.

So, what should we do with biodegradable plastic bags? My opinion is that if it is marked as compostable, then I will throw it in the kitchen waste. Although the plastic bag enters the kitchen waste disposal link, it will bring some troubles to the disposal, and it may be separated as an ordinary plastic bag Go out, but I believe that with the development of technology, there will be treatment facilities for biodegradable plastic bags. If it is not a fully degradable plastic bag, it is recommended to reuse it and throw it into the recyclable trash can for recycling and reprocessing.

No matter what material the packaging we use becomes in the future, we hope that its recycling or degradation rate will be higher and higher. But even so, the most important thing is to minimize the use of plastic bags, otherwise, the impact of millions of tons of plastic packaging on the environment every year is irreversible.
