According to the Japanese Broadcasting Association (NHK), marine plastic waste has become an urgent environmental problem worldwide. In this context, Japans large-scale chemical products manufacturers have developed a new type of environmental protection shopping bag. The shopping bags are made of materials that are easy to degrade in seawater and are expected to contribute to reducing marine plastic waste.
The bags were developed by Mitsubishi Chemical, a large chemical company, and a packaging material manufacturer in Nagoya.
The material is made of sugarcane and other plant materials, and the principle of microbial degradation of garbage in soil is applied.
Although there are not as many microorganisms in seawater as in soil, the new material is easy to degrade even in seawater. It is reported that shopping bags made of it can be completely degraded in seawater in about one year.
However, as the production process needs to be supported by advanced technology, its price is estimated to be more than six times that of ordinary shopping bags.
We hope to contribute to solving the problem of marine plastic waste by promoting this new type of shopping bag, said Ichiro bergu of Mitsubishi Chemicals sustainable polymers division
Fujitsu industries, Japans largest shopping bag manufacturer in Ehime County, is also working with qunma university to develop plastic bags that are easy to degrade in seawater and prepare for the market. At present, various parts of Japan have begun to implement the charging system for plastic shopping bags, and peoples environmental awareness is constantly improving. In this context, the extent to which new environmental protection shopping bags will be popularized has attracted the attention of all parties.
