A Definitive Guide to Medical Waste Disposal
When it comes to medical waste disposal, compliance to federal and state guidelines is essential.
However, compliance gets a bit confusing for healthcare facilities – large and small – because regulations differ between different types of medical waste and their required disposal and treatment methods. Let us help...
Depending on service volume and size of facility, healthcare organizations may generate the following wastestreams:
- Microbiological waste
- Sharps waste
- Biohazard waste
- Infectious waste
- Pathological waste
- Pharmaceutical waste
- Chemotherapy waste (or other chemical waste including laboratory reagents, disinfectants, film developers)
Waste segregation is the first step in maintaining compliance with hazardous waste disposal (even though not all medical waste is deemed hazardous). State and federal guidelines for medical waste management clearly define how each category of waste should be collected and disposed of; for example there is a big difference in how sharps can be disposed of and how chemotherapy waste should be disposed of. Daniels Health understands the importance of clarity, especially when it comes to federal and state guidelines for the storage, transport, and the disposal of non-hazardous and hazardous medical waste.
Storage, Transport, and Disposal Guidelines
According to the Environmental Protection Agency, regulations for the storage, transport, and disposal of medical waste depend on the type of medical waste under consideration. Disposal methods for a syringe with needle are different than disposal of an animal carcass or human tissues.
Specificity is key. For example, when it comes to disposal of sharps, they are to be placed into a container that is:
- Shatterproof, durable (due to heavy handling), leak-proof, and puncture resistant
- Marked with a universal biohazard label
- Designed so that during handling, contents won't fall out
- Equipped with a safe yet accessible opening that enables users to easily determine when the container is full
Guidelines for pharmaceutical waste disposal are more complicated, specifically dependent upon the definition of various hazardous waste categories. The EPA classifies pharmaceutical waste by four categories:
- Regulated hazardous pharmaceutical waste
- Non-regulated hazardous pharmaceutical waste
- Non-regulated "non-hazardous" pharmaceutical waste
- Minimization of pharmaceutical waste
* Other considerations must be factored into these categories such as dosages and form of the pharmaceutical waste (tablet, capsule, injectable).
The Responsibility of Healthcare Facilities
Healthcare facilities are responsible for checking with state regulators as well as federal agencies regarding interpretation of regulations. To remain compliant, healthcare facilities should regularly refer to be rulings and summaries for management standards of hazardous waste pharmaceuticals (42 U.S.C. § 6921-6924). State regulations may be more stringent than federal guidelines and vary from state to state, and those guidelines and regulations are routinely updated. The regulatory agencies that oversee pharmaceutical waste management include:
- The Environmental Protection Agency (EPA)
- Department of Transportation (DOT)
- Drug enforcement administration (DEA)
- Occupational Safety and Health Administration (OSHA)
- State environmental protection agencies,
- State pharmacy boards, and
- Local publicly owned treatment works (PO TW)
The aspect of defining and segregating medical waste for disposal is just the first step. Collection and transport of medical waste is also specifically mandated.
Collection and Disposal of Medical Waste
With each type of medical waste specifically defined by federal and state guidelines, it is imperative that waste is segregated prior to disposal. Removal and transport of medical waste for disposal must be carried out by individuals or companies licensed by the EPA for the collection and transport of medical waste. An individual engaged by the healthcare facility may also transport waste directly to either a hospital with appropriate disposal methods or a waste depot licensed by the EPA.
The disposal of medical waste (hazardous and non-hazardous) is primarily under the purview of the Resource Conservation and Recovery Act (RCRA). The Hazardous and Solid Waste Amendment (HSWA) attached to the RCRA regulations are also applicable in medical waste disposal and biohazard waste disposal, among other types of medical waste. The primary objective of the RCRA is to provide protection to human health and wellness and the environment from the generation, transportation, treatment, storage, and/or disposal of hazardous wastes. These objectives specify that wastes be properly treated before disposal, reducing harm to groundwater, leeching of hazardous waste and particulates into the environment, and reducing toxicity by previously removing or destroying harmful particles and/or constituents of medical waste.
When it comes to treatment standards, special requirements apply to certain types of waste with specific characteristics such as:
- Corrosive waste
- Reactive waste
- Toxic waste
- Ignitable waste
Bottom line - any hazardous waste that will ultimately end up in some form of land disposal or disbursement is required to meet all applicable treatment standards prior to such disposal. Standards applicable to hazardous waste can be found under Title 40 of the Code of Federal Regulations (CFR) §268.40.
Treatment Methods for Medical Waste Disposal
As guardians of our customers' waste compliance, we are committed to performing all treatment in a responsible manner in accordance with legislation, regulations, codes of practice, standards and licence requirements. Where regulations permit, Daniels opt for the most environmentally sustainable methods of waste treatment.
Daniels Health use thermal autoclave treatment for regulated medical waste disposal (RMW). This includes sharps, regulated medical waste and pathological waste (excluding arms, legs and torsos)… just painted a nice picture for you didn’t it! Autoclave is the most environmentally responsible process for the treatment of RMW and other infectious wastes and aligns with our mission of sustainability throughout our operations. Utilizing pressure chambers that sterilize supplies and equipment in steam "baths" of approximately 285°, the Autoclave denatures the waste by way of high pressure steam sterilization.
Autoclave chambers differ in size, with some of the largest ranging 30 feet long, 6 feet wide, and 6 feet tall. Waste remains in the autoclave for at least 20 minutes and the pressure chamber typically runs through three cycles for a total time of 60 minutes. By the end of cycle, the waste contents have been reduced (melted) and comingled with all other waste and represent a volume less than 50% of the original volume. Processed waste is then either compacted or shredded. Other 'non-incinerated' medical waste disposal options are available, including:
- Chemical - most common in the treatment and disposal of liquid wastes and chemical wastes
- Microwave (irradiative) - microwave or irradiation methods are effective for infectious wastes and sharps wastes, but are not intended for use with pathological waste
The focus of technological advancements in the US in regard to medical waste disposal is to reduce hazards to humans and the environment. The most common method for the treatment and destruction of non-RMW medical waste is through incineration, utilized most commonly by Daniels Health for chemotherapy, pharmaceutical and other forms of hazardous waste. Incineration continues to be the most cost-effective method of medical waste disposal, with incinerators burning at temperatures the range anywhere between 1000°F and 2000°F. In the US, research and development continues to seek ways to reduce emissions produced via incineration. The Clean Air Act requires the EPA to review standards for medical waste incinerators every five years, with requirements for lowering emissions from air pollutants and improving segregation and medical waste management methods.
The number of medical waste incinerators in the US has declined approximately 25%, while at the same time promoting less expensive and more environmentally friendly alternatives such as autoclaving. Nevertheless, a fifteen-year plan for upgrades for hospital, medical, and infectious waste incinerators were to be met by February 2018 in regard to existing facility compliance under CAA §129. The ultimate goal of the EPA is to end all incineration methods in the US, promoting instead autoclaving/landfilling alternatives that would reduce the amount of toxic air emissions annually
