The unique needs for varied medical waste disposal for labs

In any sort of civilized and developed area, medical care becomes more than a luxury. The industry of caring for others encompasses a broad variety of situations ranging from accidents and injuries to illnesses and allergies. In each case, care both consumes resources and creates waste. This waste is anything used to treat an individual that is unable to be used again without risk of infecting another individual in some way. This translates to infections, but some do not realize that the unique balance of genetics and chemicals within the body can be infectious as well to others. In order to contain any possible issue, the majority of materials used to treat, heal, or assist an individual is disposed of. Much of that is determined to be biomedical waste, which is any kind of waste containing infectious or even potentially infectious materials. It also includes innocuous items such as packaging, unused bandages, infusion kits, and other laboratory items that are removed to ensure a sterile and safe environment for future care.

Another aspect would be ‘sharps,’ which are disposed of regardless of use or not in the very real case of their nature. Needles and blades that are easily capable of piercing the skin can not only spread infection, but create opportunities for such. Therefore, they are treated with great care and if even the possibility of infection is present, they are dealt with accordingly. Biomedical waste can be solid or liquid as well. In addition to the materials mentioned, it also includes materials like blood, microbiological cultures, portions of the body from tissue samples to portions that had to be amputated, and any bodily fluids. For the same reasons they are disposed of properly in a medical care environment, this form of waste is not handled by normal trash removal. To prevent further infection, it must be handled carefully and dealt with accordingly. Such requires specialized equipment and measures.

Generation of material

Another location known for generating medical waste are laboratories. Earlier, the concept of a hospital laboratory was mentioned. These are purpose-built locations on-site. By no means are these the only laboratories available. Offsite labs are often far more expansive and diverse in their nature of research. These locations are possibly the most diverse in their forms of medical waste because of that variety. Medical waste comes in many forms, including infectious and pharmaceutical waste that is common with hospitals and nursing homes. While hospitals and laboratories do often create similar waste, labs often create larger quantities of chemical and radioactive wastes. Depending on the nature of their research, laboratories can create a broad range of waste. In facilities where medical issues are being researched such as treatments or cures for current diseases, the medical waste will be far more infectious. In others where the focus is on advancing medical technology, the proportion of sharps will likely be higher. Regardless of the nature of research, laboratories will create a uniquely hazardous form of waste that must be disposed of appropriately.

Methods of disposal in Laboratories

The entire point of disposing of materials is to remove them from the area. However, this simply means moving them somewhere else. In order to truly dispose of materials is to make them both no longer a threat in any way, and to make them unrecognizable. This process will either drastically reduce any risks, or eliminate them entirely. Depending on the nature of the material, several methods are available. Biomedical waste is often incinerated, turning any infectious waste into ash. The controlled burning of chemical and biomedical or surgical waste is the most often used form, with some reports claiming up to 90% of medical waste being disposed of in this fashion. Some states prohibit this form of disposal because of the environmental impact, but other options do exist.

When incineration is not an option, another method is to use auto-claving. Autoclaves are sealed chambers that combine intense heat and pressure, occasionally steam as well, to sterilize medical equipment. Doing this will destroy any microorganisms on surgical waste, allowing the tools to be used again. This sterilization technique will destroy any living material, making it safe for further use, and preventing the waste from entering a landfill once dealt with. Such makes this method quite popular with labs and hospitals, as the materials can be reclaimed instead of disposed of and new being required. Because of this, strict measures are in place to ensure the safety of materials reclaimed from an autoclave such as extensive training for operators, and appropriate time to ensure sterilization for any biomedical waste.

When the waste is liquid, or small quantities of waste, a sterilization solution can be used to neutralize any and all biological presence. Often, a 1-10% solution of bleach can be used to disinfect the materials. Solutions of various disinfectants such as sodium hydroxide also may be employed depending on the nature of the liquid waste. Additional methods include the use of alkaline digesters to dissolve and destroy materials, or even the use of microwaves to instantly kill any living or infectious material. Regardless of how waste is neutralized, unless the autoclave is used to reclaim materials, a shredder of some sort is often employed to further destroy the material as a final step before being done with the disposal process. It is important to ensure that all possible steps are taken not only to remove the threat of infection, but also to keep from further injury to any individual that comes in contact. This means ensuring the sharps are destroyed as much as the infections neutralized.
