Everyone knows that China has long been encouraging Chinese people to reduce the use of disposable items and try to use reusable cloth bags. Supermarkets have also begun to take corresponding measures. For example, shopping bags need to be purchased. This is also To encourage people to go out shopping and pack their own cloth bags. These measures are also to protect our environment, prevent pollution from reaching uncontrollable levels, and live greenly. Japan has developed a plastic bag that can be degraded in seawater in about a year. This is undoubtedly an achievement that has made a great contribution to mankind.
One year? For people who don’t know how long it takes to degrade ordinary plastic bags, it feels very long. In fact, one year is very short, which is a great improvement. According to research by relevant personnel, it takes an incredible amount of time to degrade ordinary plastic bags in the soil. It takes about two hundred years to degrade. Some researchers originally believed that only when plastic bags are completely decomposed into carbon dioxide and water can they be considered completely degraded. , so the degradation of ordinary plastic bags is estimated to take more than 200 years. If there are no plastic bags developed in Japan that can degrade in seawater for a year or if relevant measures are not taken to control the use of ordinary plastic bags, the earth's environment will be in danger.
The plastic bags developed in Japan that are degradable in seawater contain a variety of plant ingredients, such as sugar cane. This degradable plastic bag only takes about a year in seawater. Its degradation principle is as follows: The principles of microbial degradation of garbage in the soil are similar, which is also the magic of this research. The greatly shortened degradation time is also inseparable from the composition of plastic bags.
Although this kind of plastic bag is good, its price is much higher than that of ordinary plastic bags, which is six times that of ordinary plastic bags.
The advent of this kind of biodegradable plastic bag in seawater is a good thing, but in terms of its price, it cannot be popularized. Corresponding measures must be taken to control the use of plastic bags. At the same time, R&D personnel are also actively researching a variety of technologies to utilize in environmental protection.
