Tokyo Metropolitan Government

Tokyo Super Eco Town Project Outline

1. What is the Tokyo Super Eco Town Project?
The Tokyo Metropolitan Government (TMG) has been proceeding with the development of waste treatment
and recycling facilities utilizing TMG owned land in the city’s waterfront area. As one of the central
government’s Urban Renaissance projects, this aims to propel Tokyo’s transformation into a recycling basedsociety by resolving the issue of waste in the Greater Tokyo Area and providing locations for environmentalindustries.
Facilities for PCB-containing waste treatment and waste fuel electric power generation are operating in theInner Central Breakwater Landfill site, and in the Jonanjima Island district, facilities for the recycling of mixed
construction waste, food waste, and used IT and other electronic devices are in operation.
The TMG will strive to resolve waste problems by promoting the development of advanced and highly reliablewaste treatment and recycling facilities that will boost the percentage of treated waste and reduce the final
volume of disposed waste in Tokyo.

2. Fundamental Concepts
zzz

The TMG will secure the necessary metropolitan government owned land for locating the facilities,
decide upon the type of facilities to be developed and which companies will operate them, and coordinate
and promote the entire project.
For the treatment of PCB-containing wastes, the Japan Environmental Safety Corporation (JESCO) willdevelop and operate a facility for regional treatment based upon various laws including the PCB Special
Measures Law (Law Concerning Special Measures for Promotion of Proper Treatment of PCB Waste)
and the Japan Environmental Safety Corporation Law.
Businesses that have been selected based on their applications will acquire TMG land and be responsible
for the development and operation of their respective facilities.
The businesses will be responsible for procuring their own funds and ensuring business feasibility. Theywill also be responsible for undertaking any legal procedures for city planning decisions and obtaining
facility permits, etc. required for the development and operation of the facilities.

PCB decomposition reactor[Business Overview/Features]
Under the leadership of the national government, the Japan Environmental Safety Corporation promotes theregional treatment of PCB containing wastes through five centers located throughout Japan (Kitakyushu, Osaka,Toyota, Tokyo, Muroran).
This facility was established for the chemical treatment and detoxification of PCB containing wastes(high-voltage transformers, high-voltage capacitors, ballasts, etc.) from Tokyo and the three neighboring
prefectures of Saitama, Chiba, and Kanagawa. Treatment operations started up in November 2005 and willconclude by 2014.
This facility treats highly concentrated PCBs by hydrothermal decomposition and low concentrated PCBs bydechlorination decomposition.

Tel: 03-6327-3190
http://www.tgn.or.jp/tokyorp/Power generator[Business Overview/Features]
In this facility, industrial wastes such as plastic wastes and crushed/separated residue of construction wastes arereceived for gasification and melting treatment. Ash is melted under high temperatures into slug to be recycled
as construction material. In addition, 23,000kW of power is generated by recovering both the heat generated
through this process and the waste heat of medical waste treatment. Metals such as iron, copper and aluminum
are sold as valuable materials. Infectious medical wastes from medical institutions are incinerated in exclusive
furnaces, and the waste heat is used for power generation. This facility is one of the largest of its kind in Japan.
It aims for 100% recycling by combining material recycling and thermal recycling.

Thorough pre-treatment is undertakenbefore automated treatment[Business Overview/Features]Construction and demolition wastes that are difficult to be recycled are received at this facility. Using arecycling system with high-precision separation made possible by state-of-the-art technology, a recycle rate ofover 90% has been achieved. This facility takes the fundamental position that “wastes are products” and aims
for the boundless recycling of precious waste resources. Greater recycling efficiency will be sought throughadvancements in separation technology while also promoting a balance between people and machines.
Environment-conscious operations are also conducted such as construction of a 10 meter high windbreak wall
to care for the surrounding environment and equipping the facility with a high performance dust filter to protect
the health of the staff.

were introduced to achieve this high rate of recycling. Due to this, this facility was accredited as a nationallysubsidized facility, the first private construction-related industrial waste treatment facility to receive thisqualification.
(1) Achieved automated rough selection of waste by introducing a “roll screen unit”(2) Achieved high utilization of earth and sand by introducing a “grinding and washer treatment unit”(separation by difference in specific gravity)(3) Achieved utilization of coarse particles, etc. as a secondary raw material for steel manufacturing(Eco-Form)[Business Contents]

Heavy equipment operations before shredding[Business Overview/Features]This facility receives waste such as used iron metal matrix composites as well as electric/electronic equipment
and information communication equipment. The products are disassembled and separated, and proper methodsof treatment are undertaken after an accurate assessment of the composites. This leads to an extremely purerecovery of materials. As all items that have undergone the crushing treatment can be shipped out as raw
materials for the materials industry, zero emission of waste (zero landfills) has been achieved.

Ingredient for formula feed[Business Overview/Features]This facility receives and dries food waste (food scraps) to manufacture ingredients used in formula animal feed
for the pork and poultry industries.
The advanced technology of the “low temperature vacuum drying equipment” is based on the principle of“water evaporation by deep oil frying” to manufacture feed. Feed can be manufactured in approx. 90 minutes
per treatment cycle (10 tons), allowing large volumes to be treated in a shorter period of time than othercompost or feed production methods.

Tel: 03-5492-1461
http://www.bio-energy.co.jp

Fuel cell and methane gas holder[Business Overview/Features]This facility accepts food waste that had traditionally been incinerated rather than recycled because ofseparation difficulty. Using a methane fermentation system, methane gas is generated as fuel for application infuel cells and gas engines. Approximately 24,000kWh of power (equivalent to electricity for about 2,400households) is generated a day. About 60% of this is sold to an outside corporation. Because this power isgenerated by biomass, it has been appraised as a natural form of energy, receiving certification as a green energy.
It also helps to halt global warming by creating electricity from food waste. It reduces carbon dioxide emissions
by an annual 5,000 tons.
