Ariake Incineration Plant, Clean Authority of Tokyo

Today I will talk about waste, actually waste processing of Clean Authority of Tokyo. How they process their waste so the city can be very clean like that? Yes, the city really really clean!

The Background and Purpose of Establishment

The 23 cities and The Tokyo Metropolitan Goverment had discussed for many years. One result of these discussion was that, on April 1st, 2000, the duties of municipal waste management were transferred to 23 cities. At that time, it was decided that each of the 23 cities would independently manage its own waste collection and transfer, while management of intermendiate treatment (incineration, pulverization, etc) was determined to be handled jointly. This was due to the presence of some cities that had no incineration plant within their cities, and for the purpose of optimizing treatment efficiency.

Each city collect/transfer waste and collect resources

1. Collection

Waste processing in the 23 cities is free of charge for household waste (excluding the disposal of waste exceeding 10kg per day), while large sized waste and business generated waste are charged.

2. Transfer

Transfer methods are determined based on the type of waste

a. Combustible waste, directly transfered to an incineration plant.

b. Incombustible waste, transferred to either the Chubo Incombustible Waste Processing Center or the Keihinjima Island Incombustible Waste Processing Center.

c. Large sized waste

Large sized waste is delivered to the large sized waste pulverization processing facility. Cities that have a transfer station conduct relayed transfer by reloading it from smaller collection vehicles onto larger vehicles. Such relayed transfer contributes to improved transfer efficiency, reduce traffic congection, and alleviation of air pollution due to exhaust.

Intermediate Treatment of Waste

1. Processing combustible waste

Incineration prevents bacteria, vermin and foul odor, and maintains a sanitary environment. By incineration waste, is volume is reduced to approximately on-twentieth. By recycling a part of bottom ash into cement materials, and by melting it into slag, the amount going to the landfill is further reduced.

Emision of hazardous subtances within exhaust and wastewater from the incineration plants is controlled and reduced to lower impact on the environment.

In an incineration plant, power generation and heat supply are performed using the heat energy of waste incineration.

If I can say, this process is high efficiency and recycle principle is very applicable.

2. Environmental measure to prevent exhaust and wastewater emissions

the measurement consist of measurement of soot and dust, heavy metal, odor, waste water emission, noise and vibration etc. To differentiate the heavy metal like from e-waste, they use melting point principle to further treatment, this treatment does to make sure that it is not dangerous again for environment.

3. Putting the heat energy generated from incineration to beneficial use.

Incineration plants use the heat energy generated from waste incineration beneficially in power generation and in supplying energy, Electricity and hot water produced at plants are used within facilities to operate the plant, thereby reducing electricity purchaces and fuel costs. Surplus electricity is sold to power companies. All of the plants sell electricity, and four plants sell heat as hot water to other facilities. Very good job, guys!!!!

From the explanation above, I can conclude that actually nothing is very high tech that we (Indonesia) impossible to do. The overall processing system have been taught in the university level in Indonesia. But the big question is Can the goverment of Indonesia make this kind of system? Yes, Should to be Yes. And then, the biggest question is Can the society of Indonesia support this system establish? Of course, Should to be yes!
