The reporter recently tracked the Japanese garbage destination, specifically visited two garbage recycling treatment plant. In Japan, garbage is mainly divided into combustible, non-combustible and resource waste three categories. Resource waste is roughly divided into plastic bottles, beverage cans, glass bottles and used newspapers. The Tokyo Metropolitan Minato Ward Resource Center is a resource waste intermediate treatment plant. Intermediate treatment is the initial sorting, classification, screening, and compression of resource waste collected from various locations to turn the waste into primary raw materials for further processing into end products. Most parts of Japan's waste sorting and treatment are assembly line operations, and the processing efficiency is very high.
Tamada Shuji, director of the Port Resource Center, told reporters that here is responsible for the initial classification and processing of a variety of resource waste, newspapers, magazines, cardboard boxes as a class, bottles and cans are classified in accordance with the material properties of the glass bottles are subdivided into transparent, teal and other colors, and so on. The main work of this intermediate treatment plant is: crushing glass bottles, plastic compressed together, the waste newspaper compressed into a huge cube, and aluminum cans and iron cans first by the magnetic separator to distinguish between the aluminum and iron cans after being distinguished into the machine and then compressed processing, the formation of a block of cubes for easy handling. Shuji Tamada said the Port Resource Center can process about 30 tons of waste paper, 15 tons of glass bottles and metal cans, and about 3 tons of plastic a day.
In Japan, household waste separation and recycling of many provisions may seem cumbersome, but it ensures that the resource waste can be recycled effectively. Such as recycling plastic bottles require unscrewing the cap, tear off the label as combustible garbage, wash the bottle and dry and flatten and then discarded to the designated recycling point, for the intermediate treatment and post-processing to provide a convenient. Paper boxes should be disassembled and bundled, and newspapers and magazines should be bundled and disposed of at the designated time. Although not everyone does exactly what is required, the conscious action of most people has improved the operational efficiency of the waste treatment plant.
Where does the waste go after the initial sorting process? With this question, the reporter contacted another resource waste processing company "Tokyo Plastic Bottle Recycling" (TPR for short), this company to "reuse resources, and work together to realize a resource recycling-oriented society" as the core concept, recycling used TPR collects used plastic bottles and produces recycled plastic sheets by screening, crushing, washing and drying them. Here, plastic bottles that have been compressed into bundles at an intermediate processing plant are delivered to a machine that first separates ordinary PVC bottles from colored bottles, and then sent to a pulverizer to be crushed and refined into recycled plastic powder through chemical decomposition and polymerization reactions. These powders are used to make plastic recycled products, from small garbage bags, business cards and buttons to large outerwear, school bags and sporting goods, covering almost all areas of clothing, food, housing and transportation.
The reporter in the TPR company to see, here the degree of mechanization is very high, the whole company less than 10 employees, but the hourly processing capacity of 1.8 tons, can be 24 hours a day operation, the daily processing capacity of about 43 tons.
Teruaki Noguchi, representative director of the company, said the plastic is made from oil, waste plastic can also be reduced through the technology, processed into fuel, and some people even waste plastic is compared to the "urban oil fields.
In Japan, the government at all levels of waste classification and recycling and management efforts to be in place. For the Japanese people, garbage classification has become their habits, is a conscious behavior of family life.
