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 !
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 system

Pleased with the equipment
We are quite pleased with our Mark-Costello sterilizer. The sterilizer has been working fine for many years. We recently purchased additional equipment from them, and are impressed with their response time and friendly service. We hope to continue a great working relationship with Mark-Costello in the future for additional pieces of equipment.
“It’s been a great relationship with The Mark-Costello Company; they are very dependable to all of our waste handling requirements and have made us aware of the importance of recycling and the upcoming waste handling issues in the future.”
“We have been very pleased with the performance and the cost savings that the trash compactors from The Mark-Costello Company have provided to our school district.”
My name is David E. and I am responsible for a Mark Costello Co. Auto-Clave, at an inflight Kitchen out here in Kona Hawaii, that is overseen by the USDA / Custom and Borders, federal inspectors. (as you can imagine that is a challenge in its self).
The products that Mark Costello Co. is producing are of good quality. The auto – clave that I am responsible for works 24/7, with very few break downs. This is the only unit available in Kona, making daily operation is critical.
It is nice to know that when I call for tech support and parts, the courteous staff always responds promptly. Being out here in the middle of the pacific, that is crucial to our operation.
I would highly recommend Mark Costello Co.
A self-contained compactor is a waste management system designed for handling trash and recyclables. It works by compacting waste within a sealed container, which prevents odors, leaks, and pests. The compacted waste is stored until it is collected, offering a cleaner, more efficient waste disposal solution.
Self-contained compactors in San Diego help businesses and property managers save on waste collection costs by reducing the frequency of pickups. They also minimize odors and reduce the risk of pest infestations, offering a cleaner and more hygienic waste management solution.
The capacity of a self-contained compactor varies depending on its model and size. However, they typically range from 20 to 40 cubic yards of waste, allowing businesses to store a significant amount of trash before requiring collection. The compacted nature of the waste also maximizes storage efficiency.
Yes, self-contained compactors are environmentally friendly because they reduce the number of waste pickups, lowering emissions associated with transportation. Additionally, they help separate recyclables from general waste, supporting sustainability efforts.
Self-contained compactors are ideal for a variety of businesses, including hotels, restaurants, hospitals, shopping centers, and residential complexes. Any property that generates large volumes of waste can benefit from the space-saving, odor-reducing, and cost-efficient features of these compactors.
Regular maintenance of a self-contained compactor includes cleaning the unit to prevent waste buildup and odors, checking the hydraulic system, and inspecting the seals to ensure they remain airtight. It is recommended to schedule professional service for routine checks and repairs to keep the compactor functioning efficiently.
