Medical Waste Sterilizers for Sale

How Can We Help?

Businesses that produce medical waste need to treat and sterilize the garbage before throwing it in the dumpster. Failure to do this is dangerous, as hazardous or infectious waste could wind up in landfills. From there, the garbage could contaminate the soil and water, and pose a threat to the environment and public health.

Sterilization, therefore, is necessary when eliminating medical waste.

Medical Waste Sterilizer


A medical waste autoclave system is a machine that sterilizes garbage. It treats the waste using steam heated to 300 degrees Fahrenheit.

The size of a medical waste autoclaving sterilizer varies. Some span as high as 10 feet and as long as 25 feet. The differences in sizes help accommodate different types of medical garbage.

The Mark-Costello Co. has been building high pressure steam autoclave type waste sterilizers for 42 years. Safe and economical treatment and disposal of biohazardous waste is becoming an issue, not only in the United States, but around the world. Along with medical facilities, our current long list of customers, both here and abroad, include International Airports and their Catering Services, Pharmaceutical Companies, Laboratories and Regional Medical Waste Processing Centers.

Systems and Applications

The Mark-Costello Co. Sterilizers use the basic principle of high temperature
steam under pressure in an enclosed fully automatic steam retort. The
sterilizer comes completely assembled and ready for simple final
connections. All chamber vessels are built in accordance with requirements
of the ASME Pressure Vessel Code. All Mark-Costello Co Sterilizers are
equipped with multiple safety features necessary when operating pressure
vessels. The entire control panel for the standard sterilizer is Underwriters’
Laboratories listed and labeled.

  • A sterilizer consists of a steel chamber sealed by a charging door. Steam is introduced into the inside chamber which is designed to withstand elevated pressures. Because air is an effective insulator, the removal of air from the chamber is essential to ensure penetration of heat into the waste. This is done by gravity displacement or vacuum.
  • A steam sterilizer is designed to use steam under pressure as the sterilizing agent. Steam or moist heat is the most effective and practical sterilizing agent in general use today. Bacteria and their spores are destroyed within minutes when exposed to direct contact with moist heat under pressure.
