No. 2 Japan Environmental Calcium Research Institute Ltd.
This time, I visited EBRI’s trend spotter, Mr. Yamamoto from the Japan Environmental Calcium Research Institute Ltd, and his office.
I got off at the Shukugawara station in Kawasaki City, Kanagawa Prefecture; after a short walk, I came to an attractive path with a row of cherry blossom trees... In front of my very eyes, there it was: Mr. Yamamoto’s office.
What is Heisei Kaizuka?
“Heisei Kaizuka” was made for the effective utilization of incinerated ash produced after burning rubbish, which means not simply throwing it away at a final disposal site, but making a system of reposition→re-use→recycle. Its banking material is a consolidated mixture of incinerated ash, water and carboniferous innocuous stabilizing agent, preventing leakage to subsurface water and rainwater infiltration through the use of rubber sheet capping. It also offers various features and functional capabilities such as solar energy generation and heliport, and can even act as an emergency shelter for potential natural disasters. Also, this resource can be dug up again after a few decades and recycled.
What triggered you to start this business?
Originally, I used to work in the real estate industry, dealing with company housing.
However, after the collapse of the bubble economy, I started to consider doing environmentally-friendly real estate business, and I thought about what is essential in this society, but hard to make at the same time… and I came up with the final disposal site.
Then I began to study the subject and finally arrived at an idea, which was “Heisei Kaizuka.”
When I worked in the real estate industry, clients were large companies. There were no large companies dealing with final disposal sites from an environmentally-friendly perspective and I began to deal with local governments.
When I thought about how to propose my final disposal site idea to local authorities, I came up with the idea of coordinating the plan through the private sector, and once it has been built, just renting it to local governments, since it would be difficult to sell.
However, local authorities picked up on issues surrounding dioxin, and started to say “rubbish thrown away at final disposal sites is dangerous!”, stating that if they didn’t rebuild incinerators and build new melting furnaces, the central government would not give the local government any subsidy money. Furthermore, they started to talk about things like melting burnt rubbish and turning it into liquid slag, which, if this was to happen, would make everything I proposed meaningless.
It was at that time the Kyoto Protocol was released and because of its energy consumption readjustment, a reduction in subsidy money by the central government was seen all over the country. I expected this to happen beforehand, and was waiting to capitalize on this opportunity.
After this event, I was contacted by a local government who was interested in “Heisei Kaizuka,” and in May 2008 I received an order from them.
After the interview, we went out for a drink. We talked about our businesses and EBRI; it was very exciting.
