Managing recyclable waste isn’t just about compliance—it’s also about protecting employees and improving the workspace. Loose boxes and packing materials can create trip hazards, block exits, and take up valuable storage areas. By using compacting systems, businesses reduce clutter and lower the risk of injury. The machines themselves are built with safety features like interlocking doors, emergency stops, and clear controls to protect operators.
They also reduce the need for manual handling and repeated trips to outside dumpsters. Beyond safety, balers support smoother operations. In fast-paced workplaces, time spent breaking down boxes adds up. With a baler, staff can load materials on the spot and focus more on their primary responsibilities. These compressed bales are also preferred by recycling companies, as they’re easier to collect, store, and process. In some cases, businesses even earn a small return from selling bales to recyclers. This not only offsets operational costs but also demonstrates a commitment to environmental responsibility—a growing priority for both customers and local governments.

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.
A vertical baler is a machine designed to compress waste materials such as cardboard, plastic, and paper into compact bales for easier storage and transportation. The materials are loaded into the machine’s chamber, where they are compressed by a vertical press. Once the material reaches the desired density, the bale is tied off and ejected for disposal or recycling.
Vertical balers are primarily used to process recyclable materials, such as cardboard, paper, plastics, and textiles. Some models can also handle non-recyclable materials depending on the design and specifications of the baler.
Vertical balers significantly reduce the volume of waste materials, which helps in organizing and managing waste more efficiently. By compacting recyclables into dense, manageable bales, vertical balers reduce storage space and transport costs, making waste management more environmentally and economically efficient.
Vertical balers offer numerous benefits in commercial environments, including reducing labor costs, saving space, and improving workplace cleanliness. They also enhance recycling efforts, which can lead to cost savings through lower waste disposal fees and improved environmental sustainability.
Yes, vertical balers are generally low-maintenance machines. Regular maintenance, such as cleaning, lubrication, and inspecting the parts like the hydraulic system and wires, ensures optimal performance. Manufacturers often provide maintenance guides and support to keep the machine running smoothly.
Vertical balers come in a range of sizes, from compact, low-capacity models suitable for small businesses to large, high-capacity balers for high-volume industrial use. The right size depends on the volume of material you need to process, your available space, and the type of waste materials being compacted.
