A waste autoclave sterilizes and reduces the volume of waste materials on site, eliminating the need for off-site processing. The device uses heat, steam, and pressure to kill pathogens and can operate in batch or continuous modes. Proper loading and periodic testing are necessary for effective sterilization.
A waste autoclave is a device that processes waste materials to kill pathogenic organisms. Such devices can achieve complete sterilization when the technician operates them correctly. They also reduce the overall waste volume, which reduces space requirements for disposal bins. Hospitals and other facilities that handle potentially harmful materials can use a waste autoclave to handle their needs on site instead of shipping the waste to another site for processing and eventual disposal.
The device contains a large chamber with a locking door. A technician can load the autoclave by hand or by pushing trolleys and trays filled with waste into the slots. Once the autoclave is full, the technician can turn it on. Increase the pressure and heat inside the chamber and create steam. This combination kills infectious organisms and can fully sterilize materials that are loaded correctly and cycled long enough.
The heat, steam and pressure inside the autoclave also destroy some of the contents, reducing the volume of the load. At the end of the waste autoclave cycle, the technician can remove the material and shred or compact it for disposal. A waste management company can take the material for transport to an appropriate disposal site. The treatment ensures that infectious organisms are not released into the environment, as none will be present at the end of the treatment cycle. This reduces the risk of spreading disease or causing environmental problems.
Some models have a design for batch operations. The technician loads and processes the material in single batches which can vary in size, depending on the capacity of the chamber. For industrial waste control, this may not be sufficient, due to the large volume of material generated. Instead, a facility may use a continuously operating design. This design feeds materials to continuously sterilize new material while ejecting processed material at the other end.
Using a waste autoclave requires periodic testing of the waste to confirm that it is clean. Technicians must also learn how to properly load the device, as overpacking or not dispensing the contents can result in imperfect sterilization. Test kits allow technicians to periodically collect samples and check for the presence of common bacteria. Regulatory authorities such as health department officials may periodically inspect the facility and take samples of their own in the interest of protecting human health and safety. If they discover violations, the facility will need to correct them and may have to halt operations until the problem is resolved.
