NKK Enters Waste Incinerator
Dismantling Business
NKK has entered the waste incinerator dismantling business
with its proprietary mobile dioxin-removal device. The company has already
landed its first order from Kamishimo-Kitayama Sanitation Union in Nara
Prefecture. The ¥633 million contract calls for NKK to dismantle
the union's existing waste incinerator in order to build a new waste
treatment plant. Work is slated to be completed in December this year.
The NKK waste incinerator dismantling system uses an
on-site mobile dioxin-removal device for full detoxification, ensuring
that pollutants are not discharged outside the area. The burner-heated
kiln is able to treat 1,000kg of dioxin-polluted waste each hour, detoxifying
it to a level below 0.1 ng-TEQ/g. Waste material generated from the
dismantling process is sorted into recyclables, dangerous substances
and toxins for appropriate treatment. Recyclable substances are put
to effective use whenever possible.
NKK has been involved in the construction of waste treatment
and recycling plants at more than 120 locations in Japan. The company
has also applied its abundant dioxin detoxifying, blast furnace rebuilding
and other plant dismantling expertise as well as environmental protection
technologies to develop the nation's first mobile waste incinerator
dismantling system.
Abandoned waste incinerators have become a pressing matter
in Japan in conjunction with dioxin-related issues. Recent years have
seen efforts for the central government to provide funds for incinerator
dismantling projects. Efficient wide-area waste treatment projects are
also becoming more common. Anticipating demand for some 500 existing
incinerator dismantling projects over the next five years, NKK aims
to secure about 20 orders, in cooperation with group companies specializing
in environmental solutions.
