What are the benefits of waste sorting?

  • Garbage classification is a reform of the traditional way of garbage collection and treatment, and a scientific management method for effective garbage disposal. people are facing the situation of increasing waste production and deteriorating environmental and economic conditions. How can we use this waste classification information management to maximize the development and utilization of China's waste resources, reduce the amount of waste disposal, compostable cutleryand improve the state of the corporate living environment? Urgent solutions are of common concern to people of all countries.

    The reason for the increase in garbage is due to the improvement of people's daily life development level and the increase of various consumption. According to statistics, in 1979, the national urban garbage removal freight was 0.3 yuan/ton, and in 1996, the urban garbage removal freight was 1.16 yuan/ton, four times that of 1979. High temperature incineration of waste will not occupy a lot of land, but it is a huge investment. Is there nothing we can do about it? There is a way, which is garbage sorting. Garbage classification is to put garbage into different categories, and make it into resources through sorting, transportation and recycling.

    The advantages of waste sorting are as follows:

    Reduce land erosion

    Some household garbage contains harmful substances, which are not easily degraded, and the land is severely damaged. Garbage sorting removes recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.

    Reduce pollution

    China uses sanitary or even simple landfills to dispose of waste, occupying thousands of acres of land, flies flying everywhere, flooding sewage, and polluting the environment.

    The waste plastics in the soil will reduce the yield of crops; the discarded waste plastics are eaten by animals, which will lead to the death of the animals. Therefore, recycling can also reduce harm.

    Turning waste into treasure

    China uses 4 billion plastic fast food boxes every year, 500-700 million instant noodle bowls, and billions of disposable chopsticks, which account for 8-15% of domestic waste. One ton of waste plastics can be recycled into 600 kilograms of diesel. Recycling 1,500 tons of waste paper can avoid cutting down 1,200 tons of paper. One ton of cans can be melted into one ton of good aluminum blocks, which can save 20 tons of aluminum ore. 30%-40% of the production waste can be recycled, so this small and profitable resource should be cherished. Everyone can also use cans to make pencil cases, which is environmentally friendly and saves resources.

    In addition, other substances in the garbage can also be converted into resources, such as food, grass, wood, and textiles that can be composted to produce organic fertilizers; garbage incineration can generate electricity, heat or refrigeration; bricks, tiles, and lime can be processed into building materials, and so on. If we can make full use of the resource potential contained in the recycling of domestic waste, Beijing alone can achieve economic benefits of 1.1 billion yuan per year. If garbage is sorted in time, recycling is the way to solve the garbage problem.

    Summarizing the benefits of waste sorting is obvious. Garbage is sorted and sent to factories instead of landfills, saving land, avoiding pollution caused by landfill or incineration, and turning waste into treasure. In the "battle" of garbage sorting between people and garbage, people turn garbage from "enemies" to "friends."
