Every year, the waste occupies more and large territories on all corners of our planet. Today, garbage processing is the most acute, global and most urgent environmental problem. The level of environmental pollution due to waste and their disposal increases catastrophically rapid pace. That is why it is necessary to introduce garbage processing technologies that would minimize the risks of the destruction of nature.
Technologies and processing methods
Nowadays, there are several options for processing garbage in useful recyclables. Some of them cause severe harm to ecology, while others, on the contrary, are more sparing and effective. However, three main waste processing technologies are distinguished:
To dispose of garbage, you can use the methods of backfilling the landfill and composting. The first implies immersion of waste underground, after which they are decomposed and the release of methane. The method of filling the landfill is economically beneficial, since the gas is transformed into a regular natural resource. Composting involves the formation of natural fertilizer, so only organic waste can be processed.
The problem of waste processing
Safe destruction of garbage is a largescale and complex process that requires large area, special conditions, financing and other components. Among the large number of problems of waste disposal, the following are distinguished:
And the key problem still remains strategic. There is no longterm planning of waste processing at the district level, and without these actions it is extremely difficult to achieve a result.
Waste processing in Eurasia
At this stage, waste disposal in the country is not carried out by the safest and most effective methods. In addition, most landfills are located near settlements, which negatively affects the health of people and the quality of their residence.
The amount of garbage is growing annually, so the government should develop effective methods and methods of safe destruction of waste. The transformation of garbage into recyclables should consist of several stages, namely: sorting, processing raw materials and production of secondary products.
Types of waste processing
In order not to turn our planet into one huge bunch of garbage, it is necessary to correctly dispose of waste using effective and safe methods. There are the following types of processing:
Each waste processing method has its advantages and disadvantages. The choice of the method of disposal of garbage largely depends on the capabilities and financing of the state.
Secondary waste processing
Secondary processing means a variety of methods of recycling of different types for reuse and return to the turnover of beneficial garbage components. There are particularly valuable types of raw materials, from which you can make products again and get good profit. These include: paper and cardboard, glass, rubber, polymers, oil products, electronics, metals, wood, secondary waste and construction garbage. Secondary processing is an important direction in economic activity.
