Answering the Growing Need for Risk
Indemnification in Soil Remediation
Development of Guaranty Products for Soil Remediation
With rising environmental consciousness
and the need to redevelop and effectively use land,
Taisei is year by year adding to its list of achievements
in soil remediation by developing soil remediation technologies,
one example of which is a permeable wall that cleans
groundwater.
For transactions involving former factory sites, new
and growing needs to lower contamination risk and fix
expenses for risk-reduction measures have been added
to needs for lower remediation costs. In response, Taisei,
working in cooperation with a non-life insurer, developed
two liability cap guaranties. Under the Shiro Cap Guaranty,
landowners can receive a guarantee that their property
is not contaminated after an examination of its history,
depth studies, and other tests are performed and show
that to be the case. The Cost Cap
Guaranty fixes remediation costs, covering additional
costs even if additional contamination is discovered.
Taisei offers a full complement of both remediation
technology and risk guaranties to promote more effective
land usage now and in the future.
Meeting Needs for Environmental Conditions
that Increase Biodiversity
Ecological Planning - The Noritake Garden Project
Responding to the need for greater biodiversity
in the local environment, Taisei conducted an environmental
revitalization project at Noritake Garden, located in
the heart of Nagoya and deep within an urban setting.
As part of this project, Taisei examined the characteristics
of the natural environment in urban Nagoya, especially
the area surrounding the Noritake Garden site. Using
the results of this study, we then created a landscape
that would allow the formation of a natural network
in which animals and insects could move among the various
green spaces in the surrounding area. We also devoted
significant effort to effectively using existing industrial
assets and the waste resulting from demolition to create
expressions of the history and unique aspects of the
location.
The entire Noritake Garden site is open for use as a
park during the day and is a favorite place to relax
for local residents. The site received the Good Design
Award 2003,the 2nd ecobuild Award,the 23rd Minister
of Land,Infrastructure and Transport Prize Winners of
Green City Awards and many other Awards.

Helping to Bring About a Recycling-Oriented
Society
New Recycling Center PFI Project for Tahara City
Companies are now expected to reduce the
environmental burden of their activities and great significance
is now placed on the creation of a recycling-oriented
society focused on reducing waste.
Taisei designed and built a recycling center for burnable
waste coming from one city (Tahara) and one town (Atsumi)
in Aichi Prefecture, and it is managing a BOT-format
PFI project in which it will operate and maintain the
recycling center, which it will retain for 15 years.
The recycling center is operated by an SPC (Special
Purpose Company) established by Taisei and four other
companies from different industries. Contributing to
the creation of a recycling-oriented society, the SPC
performed a study of the characteristics of the area
to be served and has embarked upon a scheme in which
burnable waste from households and businesses will be
recycled into carbide that will be used as a fuel and
raw material for the manufacture of steel. In addition
to contributing to the creation of a recycling-oriented
society, environmental conservation, reliability of
technology implemented, economical construction and
operation, and risk management have also been included
as important initiatives in facilities and operational
planning. In the future, Taisei will offer other regions
new proposals aimed at creating a recycling-oriented
society.
*BOT (Build, Operate, Transfer): Construction
method in which a facility is transferred after being
operated for a certain period of time after construction.
*PFI (Private Finance Initiative): Projects for pursuing
the construction, renovation, etc. of public facilities
with capital and other inputs from private sources.

In an age of the need for preventing
global warming
Technology of producing fuel grade ethanol
Construction industry in Japan is trying
to reduce and recycle construction and demolition wastes
that account for 20% of all industry wastes because
the greenhouse gas emissions are needed to be reduced
throughout all over the world.
Taisei Corporation is planning to produce fuel grade
ethanol that can contribute to reducing CO2 emissions
and could be an alternative energy resource to petroleum
oil using waste woods from construction debris.
Taisei Corporation has established the company to produce
fuel grade ethanol from construction waste woods as
the largest stockholder of the one and this company
is expected to diffuse the use of ethanol-blended gas
and tackle the tasks of developing global warming countermeasure
technology.
Bringing Back Beautiful Marine
Environments with Appropriate Analysis and Clean-Up
Coastal Clean-Up Technology
In coastal areas where water quality
continues to worsen, tidal flats are being revived
to help restore the ocean's ability to clean itself.
Taisei is engaged in just such an experiment in
Mie Prefecture's Ago Bay, famous for cultured
pearls. There, it is using sludge dredged from
the ocean floor to make artificial tidal flats
and creating marine environments to foster the
growth of eel grass. Taisei is also performing
exhaustive studies of the tides and water quality
in the inner bay, which is suffering from worsening
water quality, and developing an "Aquatic
Simulation System" to produce high-precision
forecasts of changes in seawater and marine ecosystems.
Taisei is working from the perspectives of both
cleaning technology and analytical methods to
achieve its goal of restoring and improving aquatic
environments.
