A greener future: created packages that degrade in seawater Source:

coming Soon in Japan, more expensive packages, but they are environmentally friendly

The fact that our planet suffers from a surfeit of plastic waste on land and the oceans, knows almost everyone. First, all visible to the naked eye — look out the window, and you will surely see on the ground plastic bottles and bags. Secondly, about the problem of humanity is spoken daily in the news. To save the planet, many countries are trying to reduce the amount of plastic waste and much success in this business reaches Japan. Earlier, the government ordered merchants to charge customers not less than 2 yen (about 1.36 ruble) for each plastic bag — it is believed that through such measures, people will be less likely to use them. Anyway, packages, people still needed and actively being used, so recently, Japan had created a material that decomposes faster than the plastic. So, it is ecologically harmless and familiar, but what is its drawback?

New replacement plastics

About creating a new material for making packages, said the Japanese . Worked on development of one of the units of the Mitsubishi — known car manufacturer. Details about how employees have managed to create a new material at the moment. But journalists know what raw materials, packages are made, how they look and what is their only drawback.

So look new packages from Japan — it is customary to "t-shirts"

It is Reported that the new material based on vegetable raw materials, among which is sugar cane. This perennial plant grows in the tropics, it is not able to harm the environment and human health. What other elements used in the production are not reported, but among them there must be something "not natural". According to the Japanese publication, in sea water made from a new material packages decompose in about a year. Sounds like a long time, but when you consider that the current plastic products do not decompose for millennia, this is an excellent result.

pollution of the oceans

The Developers emphasize that the packages particularly quickly decompose in sea water. The fact that it inhabits much less bacteria than on land, because of which plastic products can not disappear over a thousand years. What caused rapid decomposition, the researchers did not report. It may well be that "natural" material that attracts more bacteria, which jointly can split the package.

This picture can be seen almost anywhere in the world

As mentioned above, informed the government of Japan urged the outlet owners to charge people extra for plastic bags. Perhaps, in addition to the use of new packages, the authorities will introduce several innovations. According to plans, by 2050 Japan will cease to be a source of debris falling to the ocean.

As for the drawback of the packages of new material — it lies in the fact that their production requires large forces. Accordingly, they will be more expensive than the current plastic bags. The exact cost is still unknown, but it is reported that the price will be higher about six times. Maybe it will encourage people to abandon such packages and transfer to paper materials. The paper also decomposes in about a year.

In General, Japan should be praised. The fact that the fast decaying material in the past 5-10 years has been developed a lot, but ready-to-use products of them showed only one. For example, in 2017, my colleague Vladimir Kuznetsov told about the new eco-friendly polyethylene . He, too, was created on the basis of vegetative raw materials, but at the moment in the shops of our country used ordinary polyethylene, which is superlatively safe for the environment. In Japan, a new package will be clearly embedded samples already exist, and the plans of the authorities seem to be very serious.

But to save our planet one reduction of the production of plastic little. Simultaneously with the creation of eco-friendly materials, it is important for scientists to invent a way to clean up existing waste. About one interesting technology for the destruction of plastic waste we have been told — last year, scientists proposed a method of splitting the plastic to carbon dioxide and water. Read more about this technology can be read .
