It seems that scientists finally found a way to rid the planet of debris. Imagine one plastic bottle in nature decomposes for more than 100 years! What can we say about whole garbage dumps and tons of waste on them.
MICROBES AGAINST GARBAGE
The industrial production of plastic has generated more than 8 billion tons of waste in the world, and 80% of them are not processed. The discovery of English scientists can save humanity from debris. Changing in the laboratory the structure of one of the bacteria found in Japanese landfills, the researchers created mutants that devour plastic. It sounds threatening, but it's not worth worrying, because these mutants, being mutated bacteria, are visible only under a microscope and for people do not pose a danger. The enzyme synthesized in the laboratory is completely harmless to the environment and recycles plastic in just a few days! Week against the whole century of natural decomposition of waste! A real breakthrough in recycling garbage - to this day a very time consuming and expensive process. By the way, like many important discoveries, this is the purest chance. Scientists did not intend to create something like this, they simply studied bacteria from different landfills, but received an invention that could save the Earth in the future.
The man filled up with garbage not only his own planet, but got to space. For more than 60 years of its development, hundreds of thousands of debris of various space technology have accumulated in orbit. This becomes a problem, since a collision with them can turn into a catastrophe not only for the satellites, but also for the ISS crews and even for us.
SPACE CLEANING
Various specialists have already proposed a lot of methods for cleaning the Earth's orbit from unnecessary trash: giant magnets, space networks, tug-boats and much more. Now a team of scientists from China came up with the idea of splitting the largest fragments of space debris from super-powerful satellite lasers. Formed fragments can later be burned in the atmosphere or collected and sent away from the Earth, experts say. According to their calculations, it is quite feasible to create and launch such satellites, but the efficiency of their operation will depend on the height at which they will be located and at what angle the garbage will be fired. The wrong position of the satellite can several times increase the time of destruction of debris and energy consumption.
In the meantime, scientists from Tomsk have developed a new way to purify water of all kinds of impurities. At first glance, it is very radical and is based on the explosive destruction of droplets. What kind of principle is this?
EXPLOSION DROPS
If the contaminated water is heated to 300-500 degrees, the liquid will evaporate, incombustible impurities will precipitate, and combustible, respectively, will burn out. After the condensation of the steam, purified water will be obtained, which can be reused, for example, for technological needs. Such a method of purification is useful in industrial enterprises. Its main advantage is the ability to use secondary energy resources. For example, smoke boiler plant in the factory. Such water purification is much cheaper than analogues and does not harm the environment.
It would seem that the problems of ecology are the problems of states, not ordinary citizens. However, every time throwing out trash on the lake, in the forest or in the field, think about the numbers. Simple office paper decomposes for about 2 years, iron - 20 years, and foil, batteries and plastic - more than 100. So you can count on scientists and politicians, but you always have to start with yourself.
