The main advantage of on-site treatment is control. When regulated waste is treated promptly, you reduce the time it sits in holding areas and cut down the number of times it must be moved or stored. That can lower exposure risk, reduce odor and leakage concerns, and create a cleaner, more manageable waste stream overall.
From a compliance standpoint, the biggest value is consistency and documentation. Many facilities want repeatable cycles and clear operating procedures so they can demonstrate due diligence during internal audits or external inspections. A system that supports cycle verification, operator accountability, and clear operational logs helps you stay organized and reduces the chance of “we think we ran that load” uncertainty. Operationally, shredding after sterilization can make downstream handling easier. Treated waste is typically less recognizable and more uniform, which can simplify storage and transport within the facility. It may also help with space planning, since reducing volume can mean fewer containers sitting in your waste room and fewer emergency overflow situations during busy weeks.
Cost control is another major driver. While every facility’s math is different, on-site treatment can reduce reliance on frequent hauling, limit surcharges tied to certain regulated waste categories, and help stabilize budgeting. Instead of reacting to fluctuating pickup needs, you can build a routine around your own throughput, staffing, and schedule. And just as important, it supports confidence. Infection prevention teams and facility managers often want a solution that’s straightforward for staff and easy to standardize across shifts. When your waste workflow is predictable, it’s easier to train new team members, spot process issues early, and keep the facility running without interruptions.

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

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.
Size reduction equipment refers to machinery used to reduce the size of bulk materials or solids into smaller, more manageable pieces. This equipment works by applying mechanical forces, such as shearing, compression, or impact, to break down materials into smaller particles or pieces suitable for further processing.
Size reduction equipment can handle a wide range of materials, including plastics, rubber, metals, wood, food products, chemicals, and pharmaceuticals. It is commonly used in industries such as manufacturing, recycling, and agriculture to process raw materials into more usable forms.
The primary benefits include improved material handling, more efficient processing, better product consistency, and increased productivity. Size reduction equipment also allows for easier transportation and storage of materials, and in some cases, enhances the efficiency of other production processes.
Selecting the appropriate size reduction equipment depends on several factors, such as the type of material being processed, the desired particle size, throughput requirements, and operating conditions. Consulting with an expert or manufacturer can help ensure you choose the right machine for your specific application.
Regular maintenance is essential to keep size reduction equipment operating efficiently. This includes checking for wear and tear on critical components, ensuring proper lubrication, cleaning, and monitoring machine performance. Preventive maintenance can help extend the lifespan of the equipment and reduce unexpected downtime.
Yes, there are various types of size reduction equipment designed for different purposes. Common types include crushers, grinders, mills, and shredders. The specific machine you need depends on the material’s hardness, moisture content, and the desired final product size.
