The reuse factor is how much resale extends the life of a product. When calculating production, logistics and disposal, the different stages of a product's life were summed up: from CO 2 emissions to consumed resources. To estimate emissions of CO 2 , water and energy , platform experts used the international database Ecoinvent . It was created in order to find out how much resources are spent on the production of cotton fiber or the transportation of cars by road train. To calculate the amount of materials used, Avito used data from manufacturers and scientific publications, and then revealed the average value by category.

Logistics costs were estimated in two stages. At the first stage, they calculated the average moible number data path to the ports or airports of Russia. On the second, the remaining section of the land route to a specific region was calculated. Disposal costs depended on the methods that prevail in each of the categories. For electronics, GESP figures were used . What does it mean The main function of the ozone layer is to protect the Earth from ultraviolet radiation that comes from the sun.



Ozone holes are places where ozone concentration is low. In 1974 , scientists found that ozone holes appear when sunlight comes into contact with substances containing chlorine or bromine. Derivatives of these compounds at low temperatures in the atmosphere can destroy ozone.  in 1985 in the Southern Hemisphere over Antarctica. At the beginning of 2023, scientists told when the ozone layer on Earth will be completely restored. Their predictions appeared in a scientific report by the World Meteorological Organization.
