A waste grinder works by using sharp, fast-rotating blades to shred leftover food into fine particles. These particles can then be easily managed through composting, wastewater systems, or other processing methods. This not only improves sanitation but also reduces the load on landfills. Some systems are designed for continuous use, making them a good fit for high-volume operations.
For companies already using systems like industrial waste compactors or industrial waste shredders, a waste grinder adds another layer of efficiency. It can even be paired with conveyor systems or slider bed conveyors to streamline the movement of organic waste to collection points. Many operations also benefit from combining food grinders with cardboard balers or modern waste systems, especially when managing mixed waste streams.

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

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 food waste grinder is a device designed to efficiently break down food scraps into smaller pieces. It works by using a motorized grinding mechanism to shred food waste, making it easier to dispose of through plumbing systems or other waste management methods. It helps reduce food waste volume and supports cleaner kitchen environments.
Using a food waste grinder helps reduce the amount of food waste sent to landfills, leading to a reduction in waste and environmental impact. It also saves space by eliminating the need for composting or storing food scraps, and it can help prevent odors and pests in your kitchen by ensuring waste is disposed of immediately.
Yes, food waste grinders are environmentally friendly. They reduce the need for food waste to be sent to landfills, where it can contribute to methane emissions. Many waste grinders connect to sewer systems, helping waste break down more efficiently. Some models even allow for the repurposing of the waste in composting systems.
While food waste grinders can handle a wide range of food scraps such as fruits, vegetables, and small amounts of meat, they should not be used for hard bones, fibrous materials, or large amounts of grease. Using non-recommended materials can damage the grinder or cause blockages in the plumbing.
Maintaining your food waste grinder involves regularly cleaning the unit to prevent odors and buildup. Run cold water while using the grinder to ensure smooth operation. Periodically clean the grinding components using grinder-safe tools or citrus-based cleaners to remove debris and buildup from inside.
Food waste grinders typically use minimal electricity, but their energy consumption depends on usage. While the power required is low, it’s important to run the unit only when needed and avoid overloading it. Many models are energy-efficient, ensuring they don’t significantly affect your energy bill.
