Exploring the Importance of Waste Acceptance Policies

A healthcare facility generates many different types of waste, some of which are biohazardous and need to be separated from other waste streams for treatment prior to end disposal. On average, hospitals in the U.S. produce 5 million tons of waste per year. The World Health Organization (WHO) states that out of the total amount of waste generated by healthcare activities, about 85% is general, non-hazardous waste, and the remaining 15% is considered hazardous material that may be infectious, toxic, or radioactive.

As a waste generator, a healthcare organization is responsible for adequately sorting the waste it produces and preparing it for disposal. There can be safety, compliance, and financial consequences if done incorrectly. In the U.S., medical waste is primarily regulated at the state and local levels, which can contribute to confusion among healthcare providers; therefore, it is crucial to understand the regulations that waste providers should follow to manage waste correctly.

The Relevance of Waste Acceptance Policies

Waste Acceptance Policies (WAPs) are a waste vendor’s requirements outlining what it will and will not accept, and under what conditions. These policies are often tied to considerations such as:

  • Regulations
  • Permit conditions
  • Business decisions
  • Safety
  • Operational capabilities

A Waste Acceptance Policy, which is often included with and incorporated into the service contract, may be stricter than applicable regulations. Healthcare facilities need to ensure that WAPs from all of their waste vendors are shared with those within the organization that are responsible for waste management. Stericycle’s WAPs are available online for ease of reference.

For its core medical waste services, Stericycle has a WAP for “Non-Incineration Services for Regulated Medical Waste and Sharps” and one specific to “Incineration Services.” The applicable WAP will depend on the waste streams generated and the services purchased.  For non-incineration services, most medical waste will be autoclaved.

Autoclaving: Autoclaving is the primary method for treating regulated waste. This process relies on steam at high temperature and pressure to kill pathogens and render materials non-infectious.

Incineration: Incineration burns regulated waste at elevated temperatures and reduces it to ash. Incineration is the recommended treatment option for some types of regulated waste such as pathological waste, trace chemotherapy waste, and pharmaceutical waste.

Understanding What Waste Streams Should be Autoclaved vs. Incinerated

Wastes Acceptable Under Both of Stericycle’s Policies (Autoclave & Incineration Services)


  • Biohazardous, biomedical, infectious, or regulated medical waste as defined under federal, state, or local law.
  • Waste known or reasonably expected to contain a pathogen.
  • A waste or reusable material derived from the medical treatment of an animal or human, which includes diagnosis and immunization, or from biomedical research, which includes the production and testing of biological products.

Sharps Waste (if containerized):

  • Any object currently contaminated with a pathogen or that may become contaminated with a pathogen through handling or during transportation and capable of cutting or penetrating the skin or packaging material.
  • Needles, syringes, scalpels, broken glass, culture slides, culture dishes, broken capillary tubes, broken rigid plastic, and exposed ends of dental wires.

Wastes Acceptable for Incineration Services ONLY

The items listed below are not accepted for autoclave treatment but can be incinerated if packaged appropriately per Stericycle’s guidelines.

  • Pathological Waste (human or animal tissues, organs, limbs, surgical specimens, and other body parts)
  • Paraffin Wax Blocks (wax blocks with human or animal tissue embedded)
  • Animal Carcasses
  • Prion Waste
  • Pharmaceutical Waste (non-hazardous, non-controlled pharmaceutical waste that is not regulated as hazardous by the U.S Environmental Protection Agency (EPA), or equivalent state agency)
  • Trace Chemotherapy Waste (any waste contaminated through contact with, or having previously contained, chemotherapeutic agents)

Non-Conforming Waste: RMW and Incineration Services

Items that are never accepted by Stericycle, regardless of autoclave or incineration treatment, include:

  • Complete human remains (including heads, full torsos, and fetuses)
  • Select agents or toxins, and untreated Category A infectious substances
    • Note that for certain untreated Category A infections substances, such as waste associated with the treatment of patients with Ebola virus, Stericycle may be able to engage a subcontractor to provide services. Visit our Ebola Waste Preparedness page to learn more.
  • Controlled substances: Substances that are regulated by the U.S. Drug Enforcement Administration (DEA) or equivalent state agency (including medical cannabis)
    • Note that Stericycle does offer services for ultimate users (patients) to dispose of controlled substances. Visit our Safe Community Solutions page to learn more.
  • Hazardous Waste (any waste that is classified as hazardous by the U.S. Environmental Protection Agency or equivalent state agency)
  • Large volumes of liquid and uncontained liquid
  • Universal wastes (such as batteries, fluorescent lamps, or mercury-contaminated equipment)
  • Chemical wastes (such as solvents or cleaning products)
  • Compressed gas (cylinders, canisters, aerosol cans, or metered dose inhalers)
  • Electronic or battery powered equipment (such as cauterizers)
  • Radioactive waste
  • Loose sharps waste, or sharps waste that is not in a sharps container
  • Any container that is overweight, damaged, leaking, or improperly packaged
  • Any waste that is prohibited by law

Facilities Need a Waste Management Plan

The types and volumes of the waste streams you generate, and how they are regulated, may change over time. It is crucial to be as well-prepared as possible to address such situations. A Waste Management Plan outlines how a business will identify, segregate, store, and otherwise manage its wastes. The benefits of such a plan include:

  • Personnel safety
  • Regulatory compliance
  • Protection of the environment
  • Compliance with disposal vendor Waste Acceptance Policies
  • Compliance with 40 Code of Federal Regulations (CFR): § 60.55c Waste management plan if your healthcare facility uses incineration services
