Dear Mr. Markle:
San Ramon regional Medical Center has owned and operated a Model AS46
Mark-Costello Medical Waste Sterilizer for the past eight years. We are
pleased with performance of this equipment and have had a fine working
relationship with the Mark-Costello Company. The system continues to
function well and allows our facility to avoid the liability and high cost
of packaging and hauling untreated infectious waste.
We Anticipate several more years of operation from this waste treatment

Dear Mr. Markle:
The New England Medical Center purchased our first Mark-Costello sterilizer,
Model AS47, for the treatment of infectious waste in 1989. As our patient
load expanded, and because we were pleased with the operation of the unit,
we purchased a second sterilizer of the same model in 1993. Some years
later, with both of these units now operating. We made the decision to
purchase a third unit for back up capacity. This system is a Model AS5AS 513
which has twice the capacity ( 983 lbs. per cycle ) of the AS47. These three
sterilizers quite comfortably handle our total R.M.W load of approximately
155,000 lbs. per month.
Our cost for treatment and disposal using our Mark-Costello sterilizers is
approximately 6.5 cents per pound. The cost to package and ship untreated
waste off site using a regular medical waste hauler is approximately 18-22
cents per pound in our area.
Sterilizing infectious waste on site using Mark-Costello sterilizers gives
us the security of knowing we have taken the appropriate steps to insure
public safety while minimizing our hospital's liability.
When we have minor interruptions in the operation of our infectious waste
sterilizers we can always depend on the outstanding Mark-Costello Co.
technical service department to take care of our needs quickly and
economically. The cost to maintain three of our units average $700 each per
The New England Medical Center is very pleased with the overall performance,
reliability, simplicity, low maintenance and, above all the great cost
saving over hauling untreated waste off site that we have attained over the
past nine years of ownership.
If we find there is need for still another sterilizer, The Mark-Costello Co.
will be hearing from us again.
Environmental Health & Safety Director
Dear Mr. Markle,
I have been working in the Plant Operations of Hospitals for the past 20
years. During that time I have had the responsibility of maintaining various
autoclaves for the treatment of biohazardous medical waste.
When I came to Doctors Medical Center a year and a half ago I found myself
in charge of maintaining a Mark-Costello Co. autoclave that was nearly eight
years old. After my past experience of trying to keep a high vacuum system
with consistent problems in operation, I find maintaining the Mark-Costello
gravity fed autoclave a pleasure, as there is seldom a malfunction. I
attribute this to the fact they have kept the design simple with no need for
highly technical maintenance and high dollar repair parts.
As a point of information, the Model we operate is a AS 512 equipped with a
unique "pull out drawer" making it easy for the Housekeeping Staff to load.
This unit has a capacity of approximately 750 lbs. per cycle.
We expect to keep our Mark-Costello autoclave in operation for another 8
years or longer !
