STATE
OF POLLUTION CONTROL IN FOUNDRIES
| TYPE
OF POLLUTION |
WHAT
COULD BE DONE |
AIR POLLUTION
1.
Cupola emissions and fumes
2.
Induction and oil furnace exhausts
and fumes
.
3. Sawdust and planer chips from
pattern shops
4.
Dust from molding and cleaning equipment
|
All
of these could be controlled with
dust collectors |
WATER POLLUTION
1.
Cooling water from furnace coolers
2. Cooling water from heat exchangers
3.
Drain water from washing operations
This could be treated before draining
away.
|
These
could be treated and recycled. |
SOLID WASTE
1.
Spills from pouring operations
2.
Returns from casting operations
3.
Rejects from poured castings
4.
Slag from melting operations
5.
Sludge from wet dust collectors
All of these could be properly disposed
or sold for fill.
6.
Waste used sand from molding operations
|
All
of these could be recycled and remelted. |
WHAT
HAS BEEN DONE
|
ON
AIR POLLUTION
|
Most
foundries have dust-collectors integral
with dust producing machinery. |
| ON
WATER POLLUTION |
1.
Cooling water is invariably recycled;
but, probably not treated.
2.
Waste, or drain, water is not being
treated before disposal.
|
| ON
SOLID WASTE |
1.
All spills, returns, and rejects are
being recycled by remelting.
2.
Disposal of this type of waste has
not been determined.

ON
THE ENVIRONMENT PROBLEM
o
We agree that control of pollution is
mandatory for a cleaner environment and
we shall do our share . .
o
We note that the foundry industry is just
a minor contributor to environmental pollution;
it's just a fraction of that coming from
vehicles and other types of manufacturing
plants.
o
The foundry industry is as basic an industry
as basic can be in industry (note that
all manufacturing starts here!).
o
Despite this very important role, the
foundry industry is still a very marginal
industry in this country because it is
not fully appreciated, and thus is practically
neglected, by the powers that be (yes,
it is not quite well understood).
o
The major problem of the industry now,
as regards environment, is that pollution
control equipment add to the cost, but
not to the quality, of the product.
THEREFORE,
ERGO:
o
THE PRIORITY IN EXPENDING MEAGER RESOURCES
WOULD NATURALLY GO TO PRODUCTION EQUIPMENT
TO IMPROVE PRODUCTIVITY IN THE FACE OF
TODAY'S GLOBALIZATION.
o
OR, FACE EARLIER ANNIHILATION AND POSSIBLE
EXTINCTION.
o
HOWEVER, WE COMMIT TO DO OUR SHARE TO
AVOID THE FURTHER DEVASTATION, AND AVERT
THE ULTIMATE DESOLATION OF OUR MOTHER
EARTH!
Desolation
at its BEST; IT COULD BE WORSE!
