Mitsubishi
Heavy Industries is expanding its business in systems for
recycling the soil unearthed at construction sites. The
company has developed and refined technology for processing
soil inexpensively. It has designed processing equipment
that is compact and easy to set up at any construction site.
And it has upgraded the equipment to achieve extremely fast
processing speeds.
Getting the water
out
Removing the water from sludge at construction sites is
an important issue in recycling the earth. Mitsubishi Heavy
Industries uses absorptive materials to dewater the sludge.
The resultant soil then is suitable for foundation or construction
materials. Each of Mitsubishi Heavy Industries' recycling
units can process 10 cubic meters of soil per hour.
Mitsubishi Heavy Industries has supplied
its recycling technology to a civil engineering project
site. At that job site, the company's system recycled muddy
soil discharged from an underground tunnel to use in a dike.
The Japanese government cited that system and its performance
as a model project for recycling. And an industry organization
established to promote recycling has recognized the system
with an award. |

is what the soil-recycling equipment from Mitsubishi
Heavy Industries looks like. |

A
long with recycling soil,
Mitsubishi Heavy Industries is reducing the environmental
impact of air conditioners. It has raised energy efficiency
38% even while adopting a new refrigerant that is harmless
to the ozone layer of the atmosphere.
The new product is the result of cooperation
with three electric utilities. It stores energy during the
night, when overall demand for power is low, by making ice.
And it recovers the energy during the daylight hours. That
saves money for users. And it contributes to overall efficiency
in electric power grids by reducing the differential between
daytime and nighttime demand.
Mitsubishi Heavy Industries' new refrigerant,
HFC-407C, is completely ozone-safe. Several technical advances
have allowed for maintaining high energy efficiency with
the new refrigerant, even in comparison with other heat
storage systems. And the new system uses 90% less energy
during summer daylight hours than conventional systems do.
