One of the first things I noticed while in Japan was the cleanliness of the country. The streets were so clean with absolutely no litter in sight. Not even on roadways, grassy areas, or even in the city. This was very peculiar to me because trash cans were even harder to come by in the country. Another thing I noticed on my early morning walks to the convenience store is that people sweep the streets around their property. This is not something I’ve seen anyone do in the United States, but it is a common practice in West Africa. I even saw a similar straw broom being used. That was a fun little connection I made between Japan and my ethnic background.
What I learned very quickly is that the Japanese are very particular about their trash. Trash in Japan has to be sorted in a very specific way so that it complies with the waste management system in the country. At home, in stores, and throughout cities, trash is always separated into categories of combustible waste, incombustible waste, recyclables, and large waste. I’ve also seen some trash cans that are only specifically for bottles, further sorted into plastic or glass and cans.
On two separate occasions, one in Hiroshima and one in Tokyo, we visited incineration plants to learn more about this unique method of waste management. Usually in the United States, all trash, unsorted and all is sent to the landfill. However, due to overall lack of space and densely populated areas, this is not an option for many Japanese prefectures. For them, incineration is the best option. We learned that in Tokyo, there are 22 incineration plants between the 23 cities.
At the Suginami Incineration Plant, we saw the whole process of combustible waste incineration. First, we saw the trucks deliver the trash to the facility. The whole process of delivery is often automatic. Drivers in the big garbage truck don’t have to get out of the truck to do anything. After their trash is dumped, they drive away to collect more. Then we saw the big claws which are responsible for mixing the pulverizing the trash. The trash is then burned into bottom ash and filtered for incombustible remains. Incombustible waste is sent to the two Waste processing centers in Tokyo either by land transfer or boat transfer. Any large-sized waste is sent to the Large -sized waste Pulverization center.
Something cool that happens at these incineration plants is the heat energy generated from the waste is used to power the facility in some capacities and excess energy is sold to power companies, who can then use it to power households, schools, and other facilities. Hot water generated from the plants is also used for heated pools, botanical gardens, and other public places free of charge. This process is also apparently environmentally conscious. Toxic substances that are generated are highly controlled and reduced before releasing into the air. This method also prevents the spread of bacteria, pests, and odor in the country, contributing to a cleaner and more hygienic environment. Finally, incineration significantly reduces the volume of waste. Incinerated waste produces bottom ash, and this substance can be recycled, it can be used to make cement, burnt sand, or cooled slag. Not only have the Japanese found an innovative way to deal with waste production. They’ve also found a solution that doesn’t harm the environment, but instead can be used to enrich the live of others. By doing so, this method of waste managements contributes to fostering good health of those living in populated prefectures. and Japan as a whole.
