Frequently Asked Questions

What is medical waste?

What is medical waste? Medical waste is defined as: potentially infectious waste materials generated at health care facilities, such as hospitals, clinics, physician’s offices, dental practices, blood banks, and veterinary hospitals/clinics, as well as medical research facilities and laboratories.

The Medical Waste tracking Act of 1988 defines medical waste as “any solid waste that is generated in the diagnosis, treatment, or immunization of human beings or animals, in research pertaining thereto, or in the production or testing of biologicals.” This definition includes, but is not limited to:

  • blood-soaked bandages
  • culture dishes and other glassware
  • discarded surgical gloves
  • discarded surgical instruments
  • discarded needles used to give shots or draw blood (e.g., medical sharps)
  • cultures, stocks, swabs used to inoculate cultures
  • removed body organs (e.g., tonsils, appendices, limbs)
  • discarded lancets
What types of waste can I put in my mail back kit?

All mailback kits under 8 gallons in size are sharps only containers. The following list of waste can be disposed of using these kits:

  • Needles, syringes, lancets, broken glass with blood on it
  • Suture needles, scalpel blades, butterflies (both traditional and safety)
  • Vacutainer tubes (both plastic and glass)
  • Phlebotomy needles with vacutainer tube holder attached
  • Capillary tubes (both plastic and glass)
  • IV catheters
  • Dental anesthetic carpules with blood
  • Dental wires and endodontic files
  • Other sharp objects contaminated with blood such as box cutters and broken glass


All medical waste mailback kits 8 gallons or greater in size are considered “Medical Professional Kits”

These kits can be used to dispose of bagged and twist tied regulated medical waste. Sharps waste can also be disposed of using these kits, only when placed in a secure and properly closed sharps container. No loose sharps are permitted inside the bulk container.

How do I package my medical waste?

Per DOT and USPS regulation, our medical waste mailback kits are to be packaged as follows:

  1. Unpack the contents of your medical waste mailback kit and carefully read the packaging instructions. Make sure to keep both boxes the kit was shipped in. This is also your return shipping box.
  2. Make sure that all items under the “Contents” section are present and undamaged. If anything is damaged or missing contact Green Frontier to receive a replacement.
  3. If pre primary sharps containers are included, snap lid on container securely and place in a safe place, away from pets, children or high traffic areas in a medical office.
  4. Begin to fill sharps container as needed. If you are using a “Medical Professional kit” line the bulk container with the provided plastic bag and fill with bagged and closed regulated medical waste with the red bags and twist ties provided.
  5. Do not fill container to more than the listed maximum weight on the outside of the box.
  6. When the container is full, attach prepaid shipping label to the outside of the box, fill out and retain one copy of the hazardous waste manifest and place the remaining copies in the plastic pouch affixed to the outside of the box.
  7. Schedule a pick up through USPS or UPS. UPS is used to ship sharps only containers and USPS is the only courier who ships our “Medical Professional Kits” using our unique permit number.
What should not be placed in my medical waste mailback kit?

​In order to reduce your processing volumes and remain compliant, the following items should NOT be placed into your medical waste containers:

  • Loose syringes or needles or other sharps. Placing these items into an open waste container can result in injury to other employees or service providers
  • Loose liquids in excess of 20cc
  • Chemical or radioactive wastes
  • Hazardous, chemical, radioactive, or DEA controlled pharmaceuticals or substances
  • Compressed gas cylinders or containers under pressure
  • Any mercury containing material or device including, but not limited to, thermometers, non-contact and contact amalgam dental products, and fillings
  • Food wastes or other non-infectious garbage
Can I fill the 18 or 28 gallon “Medical Professional Kits” supplied by Green Frontier with my own sharps containers?

Yes. Any FDA approved sharps container can be placed inside the bulk mailback container to be disposed of, as long as it is closed properly and allows the bulk container lid to close properly.
