At The Mark-Costello Co., the cart dumper program is not a simple product sale. It is a comprehensive program built around understanding each facility's specific waste volumes, floor layouts, existing equipment, regulatory requirements, and staffing realities. Every installation begins with a detailed site assessment to identify where waste is generated, how it is collected, and how it needs to move through the facility to reach its final processing point. Our team helps facilities select the cart dumper model and configuration that matches the type and size of the collection carts already in use, or recommends compatible cart systems if a facility is starting fresh. Models are available to handle a wide range of cart capacities, from smaller departmental carts to large-volume housekeeping carts used in high-output departments such as surgical suites, labor and delivery units, or oncology floors. The cart dumper integrates directly with the downstream processing equipment, whether that is one of our autoclave sterilizer systems, a stationary compactor, or another waste processing unit. The result is a seamless flow from collection cart to processing system, with minimal manual intervention at every step. Controls are straightforward, designed for use by housekeeping and facilities staff without specialized training, and safety features such as cart locking mechanisms, limit switches, and guarding are built into every system. The Mark-Costello Co. also provides training, startup support, and ongoing service to ensure that every program functions reliably over the long term. Our medical waste handling programs are designed to grow with your facility, allowing for additional units or expanded capacity as your waste volumes increase.

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
Saludos,

Esperamos seguir contando con una excelente relacion de negocios en un futuro muy cercano.
Greetings,
This letter is to thank you for your services to our company. Your teamwork has been very attentive and diligent in the way it has been carried out. We are very pleased with the teamwork, the price and the quality of your services.
We expect to continue an excellent business relationship with you in the near future.
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.
Cart dumper equipment is valuable in any healthcare environment that generates significant volumes of regulated medical waste or general solid waste and relies on collection carts to move that waste to a central processing point. This includes hospitals, surgical centers, long-term care facilities, rehabilitation centers, medical office buildings, and university health systems. Facilities with multiple floors or wings that route waste to a central compactor, sterilizer, or dock area see the greatest operational benefit from a cart dumper program.
Manual tipping and emptying of heavy waste carts is a leading cause of musculoskeletal injuries among housekeeping and facilities staff. A cart dumper eliminates the need to lift, tip, or manually empty carts by mechanically raising and inverting the cart to discharge its contents. Workers simply roll the cart into the dumper, engage the controls, and the machine handles the transfer. This dramatically reduces repetitive motion strain, back injuries, and exposure to potentially contaminated materials.
Yes. Cart dumpers are designed to interface directly with a variety of downstream processing systems, including autoclaves, stationary compactors, self-contained compactors, and shredders. The key is ensuring that the dumper discharge height and position align with the receiving opening of the processing unit. During the site assessment phase, our engineering team evaluates the existing equipment and designs the cart dumper installation to integrate smoothly without requiring major modifications to the downstream system.
Cart dumpers are mechanically straightforward and relatively low-maintenance. Routine maintenance includes lubrication of moving parts, inspection of the cart locking mechanism, checking hydraulic fluid levels on hydraulically powered models, and testing safety interlocks and limit switches. The frequency of preventive maintenance depends on cycle volume and the specific model installed. The Mark-Costello Co. provides scheduled maintenance programs to keep all installed equipment operating at peak performance and to catch potential issues before they result in unplanned downtime.
Installation timelines vary depending on the scope of the program, the number of dumper stations being installed, and the complexity of the integration with downstream processing equipment. A single-station installation in a facility with existing compatible equipment can typically be completed in one to two days. Larger programs involving multiple stations, new processing equipment, and conveyor integration may require a phased installation over several weeks. The Mark-Costello Co. works closely with facility operations teams to schedule installations in ways that minimize disruption to ongoing waste management operations.
