Recycle

We aim to turn all waste into
resources,
creating a variety of recycled
products and energy.

We have the technology to
manufacture recycled
products whose raw
materials
are waste

More than 100% of the plant’s
electricity use can be
covered
by its own power
generation

Thermal recycling

A recycling method that recovers and
utilizes the “thermal energy” generated
when incinerating waste.

Material recycling

A recycling method that reuses waste
as raw materials for new products.

Thermal recycling

Waste power
generation

We contribute to carbon neutrality
by
generating our own electricity for
our
necessity.

We generate electricity by recovering the
thermal energy
generated during the waste
incineration process as steam. We
secure the
necessary power for use at the plant and sell
any
surplus to the power company. This
reduces energy
consumption and contributes
to the reduction of CO₂
emissions.

Highly efficient power generation!Owns a “turbine generator” that produces
4,950 kW of electricity

Material recycling

Recycled products made
from waste

We manufacture and sell recycled
products made from waste
materials.

*Includes recycled products from group companies.

Artificial sand (Arc sand)

Artificial sand is made from incinerated ash
that has been
calcined to render it harmless
and processed. It can be
used for various
purposes such as roadbed material,
braille
blocks, heat island measures, weed control,
and
water quality improvement.

Molten slag (Melissa)

Molten slag is a melt-processed product of
incinerated
ash, incinerated fly ash, accepted
cinders, fly ash, and
contaminated soil
generated after incineration of solid
materials. The detoxified molten slag is
utilized as a civil
engineering and
construction material.

Recycled oil

We recycle and process liquid waste
discharged from ship tank cleaning
and other
processes to produce
recycled oil that can be
used as
heavy oil. This leads to effective use
of limited petroleum resources.

RC-30･40

RC-30 and RC-40 are recycled aggregates produced by crushing concrete scraps and debris. It is used as roadbed material, asphalt, and other civil engineering materials.

RPF (Solid fuel)

RPF is an auxiliary fuel made from
waste
plastic, wood waste, and paper
waste. With
its high calorie content, it
is attracting
attention as an
alternative fuel to coal. It is
used in
furnaces at paper mills and boilers at
power plants.

Compost

We compost food residue and sludge
using a
microbial self-fermentation
system. We
generate and sell safe
and reliable organic
fertilizers. It
helps create stable soil.

Iron scrap

Steel scrap and other materials
generated at
demolition sites and
factories are cut with a
1,600 tons
guillotine shear. These scraps are
sold to electric furnace makers that
emit less
CO₂ during steelmaking.

Bagasse (Feedstuff)

Bagasse is the fibrous lees from
sugarcane
when the sugar juice is
squeezed out. About
100 million tons
of this waste is generated
annually
around the world. We import some
of
it and reuse it as livestock feed.

Car recycling

Achieve zero car waste

At our car recycling plant, we take in end-of-
life and used vehicles,
regardless of model,
year, or condition,
and properly process them
at the plant to achieve 100% recycling and
zero waste.
We sell economical and environmentally
friendly used automotive parts and
rebuilt
parts both in Japan and overseas.
