Managing food waste is a significant challenge for many businesses, especially those in the food service and hospitality sectors. The daily accumulation of food scraps can quickly overwhelm traditional waste management systems, leading to overflowing bins, increased disposal costs, and unpleasant odors. Moreover, food waste that ends up in landfills contributes to methane emissions, a potent greenhouse gas that exacerbates climate change. This environmental impact, coupled with the operational inefficiencies and costs associated with frequent waste pickups, makes food waste management a pressing concern for many organizations.
The problem is further complicated by the need to comply with stringent environmental regulations that govern waste disposal. Businesses are under increasing pressure to adopt sustainable practices, but finding cost-effective and environmentally friendly solutions for food waste management can be challenging.
Traditional methods, such as sending waste to landfills or incineration, are not only harmful to the environment but are also becoming less viable due to regulatory and societal shifts toward sustainability.
Mark Costello’s food digesters provide an effective solution to these challenges by processing food waste on-site and converting it into biogas and digestate. This reduces the volume of waste that needs to be transported and disposed of, lowering operational costs and minimizing environmental impact. The biogas generated can be used as a renewable energy source, further reducing a business’s carbon footprint.

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.
An eco-friendly food digester is a sustainable solution designed to break down food waste into organic material that can be safely disposed of or used as compost. It helps reduce the environmental impact of food waste by converting it into a non-toxic, environmentally friendly substance.
Food digesters use natural biological processes to decompose food waste. The system typically involves microorganisms that break down the organic material in an oxygen-controlled environment, turning food scraps into water vapor, carbon dioxide, and nutrient-rich compost or slurry.
Using an eco-friendly food digester helps minimize the amount of food waste sent to landfills, where it would otherwise produce methane gas—a harmful greenhouse gas. It reduces landfill waste, lowers carbon emissions, and contributes to a circular waste management process.
Yes, food digesters are versatile and can be used in both residential and commercial settings. In homes, they help reduce food waste and create compost, while businesses like restaurants and hotels can use them to manage larger volumes of food waste more sustainably.
Most food digesters can process a wide range of organic materials, including fruits, vegetables, meat scraps, dairy products, and coffee grounds. However, it’s important to avoid large bones, oils, and certain non-food items, as they may clog the system or inhibit the digestion process.
Yes, eco-friendly food digesters are designed to be energy-efficient, using minimal electricity to power the decomposition process. Over time, they save money by reducing waste disposal costs and providing an alternative to landfill waste, while also contributing to environmental sustainability.
