A sterilizer is most effective when it is treated as part of the full waste stream, not a standalone machine. That means looking at where waste is generated, how it is collected, and how it moves through the building before it is staged for pickup. When these steps are mapped out clearly, sterilization becomes a routine part of the day instead of a bottleneck.
Most facilities succeed with sterilization when they standardize a few basics: clear signage, defined container types, and simple training that focuses on what staff actually do each shift. It also helps to set rules for when waste is treated, who verifies the cycle is complete, and how records are stored. These details can make a major difference during inspections, internal reviews, or when leadership needs a clean snapshot of compliance.
Many sites also run multiple waste solutions in parallel, and the equipment needs to work together without creating extra steps. For example, a facility may manage general waste volume with a Trash Compactor Dumpster, support consolidation with a Waste Management Compactor, handle high-volume dry waste with stationary Compactors, and still maintain a dedicated path for Medical Waste that requires controlled handling and documented treatment.
Here is what facilities typically gain when sterilization is designed into the workflow from the start: Reduced handling steps, because waste is treated on-site and staged in a more controlled way. Cleaner waste rooms and improved odor control when waste is processed consistently. Clearer staff roles, which lower confusion across shifts and departments. Better readiness for audits, with routine logs and repeatable procedures. More predictable scheduling, because waste storage becomes more manageable. A Waste Sterilizer in a paramount setup should also be planned with space, access, and safety in mind. The best installations account for doorways, carts, floor drains where applicable, ventilation needs, and safe loading and unloading zones. This prevents congestion in hallways and reduces the chance of spills or mishandling. When the sterilizer is placed where waste naturally flows, staff adoption is higher, and results are more consistent.

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

To whom it may concern,
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.
Two-ram balers use separate rams for compression and ejection, allowing them to handle higher volumes, more materials, and deliver denser, more uniform bales. This design increases speed, reduces jamming, and is better suited for diverse or heavy-duty waste streams.
Our 2 ram balers can compact a wide range of materials including OCC (old corrugated containers), newsprint, PET, aluminum and steel cans, plastics, and with the optional metals package, non-ferrous scrap like copper and aluminum.
Routine maintenance includes hydraulic fluid checks, changing out wear liners, blade sharpening or replacement, and occasional adjustments to the ram hold-downs. Our machines are designed with easy service access and come with extensive support through our nationwide parts and service network.
Yes. Our Maestro™ control system lets you fine-tune compression settings, adjust bale length, and modify ejection speed. The NexDoor™ adjustable door also ensures consistent output, regardless of material type or size.
Absolutely. They’re designed specifically for industrial environments with safety features such as emergency stop controls, hydraulic lockouts, and protective guards. The hydraulic systems are built to handle continuous use without overheating or mechanical failure.
Yes, we offer full installation, training, and ongoing support for all our equipment. Our technical service team is available for routine checkups, emergency repairs, and remote troubleshooting to ensure your system stays up and running.
