Unmanaged packaging materials not only create visual clutter but can also introduce serious safety risks. Piled-up boxes can block access points, present fire hazards, and increase the risk of trips or falls. Having a dedicated baling system helps maintain order in high-traffic areas. Cardboard is loaded, compressed, and secured in one designated zone, freeing up valuable space and keeping operations moving efficiently. For many businesses, this system also saves time. Instead of having staff manually break down and move materials to exterior dumpsters, balers let teams manage waste at the point of generation.
Most units are designed with built-in safety features to support proper and secure usage. These include automatic locking doors, emergency shut-off switches, and clearly marked operating instructions. Once a bale is complete, it can be tied off and removed using basic tools or automated ejection features, depending on the model.
This predictable process reduces the chance of improper handling and ensures materials are processed consistently. The result is a more organized workplace and a faster, safer cleanup routine.
Cleaner spaces also impact how a facility is viewed during health, safety, or environmental inspections. Whether you're running a commercial kitchen, warehouse, or retail store, maintaining visible cleanliness and waste control reflects well on your company’s standards. Organized waste handling supports everything from employee morale to brand image—and balers play a key role in that system.

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

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.
A cardboard baler is a heavy-duty machine—typically powered by hydraulics or pneumatics—that compresses loose or flattened cardboard into dense, manageable bales. The user loads the cardboard into the chamber, activates the press, and waits while a metal platen applies high pressure to compress the material. Once compacted, the bale is securely bound with wire or strapping and then ejected for storage or recycling
Businesses accumulate high volumes of cardboard, which can clutter spaces and raise disposal costs. A baler can reduce waste volume by up to 90%, saving on dumpster space and collection frequency. Plus, baled cardboard is more attractive to recycling vendors—businesses may even earn revenue from selling bales. This system promotes greater workplace safety by minimizing clutter and fire hazards, while also helping meet sustainability goals and compliance with waste regulations
The most common configurations are vertical and horizontal balers. Vertical balers are compact and ideal for lower-volume environments like backrooms and warehouses—they operate with a platen that presses downward. Horizontal balers, on the other hand, are larger and suited for continuous, high-volume baling with added shearing capabilities. The choice depends on your volume, space, and material handling needs
While designed primarily for cardboard, many balers can also process paper, plastic film, aluminum cans, and more—but only one material at a time. Mixing materials in the same bale is not recommended, as it can contaminate the bale and reduce its market value. Operators should bale types separately and follow the machine manufacturer’s guidelines .
Modern balers are equipped with safety features such as emergency stop buttons, interlocks, and automatic shutoffs to prevent misuse. Operators must be 18+, properly trained, and follow manufacturer protocols. Routine maintenance—such as hydraulic checks, lubrication, and cleaning—is essential; most systems require at least annual servicing. If bales come out loose or strange noises occur, pressure settings, hydraulic fluids, or filters may need attention
Acceptable inputs include clean, dry cardboard—both flattened boxes and corrugated sheets—as these can be efficiently compacted. However, soiled or greasy cardboard (e.g., soaked with food residue), or items containing metal, plastic, or polystyrene parts, must not be baled. Such contaminants can degrade bale quality, damage machinery, and lead to vendor rejection
