Medical Waste Sterilization, Built to Code
Autoclave systems and sterilization equipment for healthcare facilities, commercial kitchens, and regulated waste processors — sold, installed, and serviced by The Mark-Costello Co. since 1973.
Sterilization equipment operates in some of the most regulated environments in the country.
The Mark-Costello Co. has been manufacturing medical waste autoclave sterilizers for over 50 years. With more than 600 units sold to customers across the United States and internationally, we've built systems for hospital networks, commercial medical waste processors, international airport catering operations, pharmaceutical companies, and university laboratories. Every system is backed by our in-house engineering and service team — the same team that built it.
Steam sterilization is the most reliable, environmentally sound alternative to incineration. Our systems are designed to eliminate all microbial life in the waste stream, meeting national and international standards for regulated medical waste treatment.
Sterilization Systems & Ancillary Equipment
Medical Waste Autoclave Sterilizers
High-pressure steam sterilization for regulated medical waste. Units treat 100 to 1,125 lbs. or more per cycle. Available in gravity-type and semi-automated configurations. Low maintenance cost, simple to operate, and designed for long service life — some units remain in operation after 20+ years.
EZ Waste Disposal System
Our semi-automated and fully automated material handling system. Reduces employee contact with untreated waste from point of generation to final disposal. Designed for facilities that need throughput efficiency without adding headcount.
Medical Waste Grinders & Shredders
Size reduction equipment used before or after sterilization to reduce waste volume and prepare material for disposal. Pairs with autoclave systems for complete treatment lines.
Hydraulic Cart Dumpers & Waste Carts
Autoclavable carts and hydraulic dumpers that integrate with the sterilization system. Eliminate manual handling of biohazardous material at every stage of the process.
