The main three methods of waste plastics treatment in countries around the world
So far, more than 9.1 billion tons of waste plastics have been produced globally . In 2010 alone, there were 4.8 million tons to 12.7 million tons of plastic waste flowing into the ocean. These plastics have spread all over the world. These waste plastics pose a huge threat to human survival. There are currently three main methods for handling plastic waste globally: First, landfill directly. The so-called direct landfill method is to fill the prepared pits with compacted materials to make biological, physical and chemical changes, and to decompose organic matter to achieve the purpose of reduction and harmlessness. Landfill is an effective method for massaging urban domestic waste, and it is also a method commonly used in China. Second, burning. Incineration is a method in which waste is placed in a high-temperature furnace to fully oxidize combustible components, and the heat generated is used for power generation and heating. This method requires strong technical support. If it is only burned violently, it will inevitably lead to greater environmental pollution. Third, composting. The domestic garbage is piled up in piles, stored at 70 °C for storage and fermentation, and the organic matter is decomposed into inorganic nutrients by the ability of microorganisms to be decomposed in the garbage. However, the long-term use of this method is likely to cause soil compaction and groundwater quality deterioration, so the scale of composting is not too large. As an ordinary people, we also need to reduce the use and waste of plastic products through our own efforts. To protect the environment, we should start from ourselves.
