Recycle to Reduce Your Waste Costs
Here's how to start a recycling program that's kind to your budget and the environment.

If your ORs produced 500,000 pounds of waste last year, you probably spent about $25,000 to dispose of it. That's twice what it need be, and not because you didn't get the best deal with the trash hauler, but because you weren't environmentally responsible enough. Here's how two activities - converting red-bag waste into clear-bag waste and recycling clear-bag waste - can save your facility thousands of dollars.

Red bag to clear bag
Our hospital generates more than 6,000 tons (that's 12 million pounds) of waste each year. Our 42 ORs were responsible for about 30 percent (788,000 pounds) of it. You can sterilize and shred much of what would otherwise be regulated medical waste to dispose of it as clear-bag waste, which usually costs at least five times less per pound to dispose of than red-bag waste (about 5 cents per pound versus about 30 cents per pound). Of course, you can't recycle this converted medical waste, but you'll save big on disposal costs, because this processed waste is safe to dispose of in a landfill.

Here at Brigham and Women's Hospital, we're lucky enough to have a service center that works with environmental services to sterilize our regulated medical waste. That department ensures our regulated medical waste meets the requirements that let it be accepted for disposal in a landfill:

  • All infectious waste must be treated (sterilized or autoclaved, for example) to make it non-infectious.
  • The waste must be deemed and labeled non-infectious.
  • Sharps must be ground up or their physical hazards otherwise eliminated.

Now, if you wanted to send regulated medical or chemical waste to an incinerator instead, you'd have to place all waste in rigid, leak-resistant containers and label it with the facility's name, address and phone number. You must label untreated waste with the international biohazard symbol. It must then travel with an infectious waste manifest.

A sorted affair
Surgical services produces the largest percentage of hospital waste, consisting generally of solid waste including paper, metal, glass and plastic, which makes up the largest portion of a healthcare facility's waste - 70 to 80 percent. About half a facility's solid waste is paper and cardboard, which can be easily reduced and recycled.[1]

Not Recycling?

Hospitals produce more than 2 million tons (that's 4 billion pounds) of waste annually. That works out to about 6,000 tons each day, and the environmental impact is steep:

  • Solid waste landfills consume enormous areas of land.
  • Incinerated waste is no better - it increases harmful air emissions.
  • Both incineration and landfills increase pollution of ground and surface water for drinking.
  • Medical waste, when incinerated, is the third largest contributor of dioxin, a potent carcinogen that causes hormonal defects.
  • Specialized disposal increases costs.
  • Facilities spend more than $5 billion per year on energy for waste processing (more than any other type of building per square foot space).

Know Your Waste Streams

A waste stream is the flow of discarded materials and fluids that eventually return to the land, water system or air. There are four such streams, as defined by Hospitals for a Healthy Environment (known more commonly as H2E):

  • Regulated medical waste. Items that have the potential to transmit infectious diseases, such as infectious medical waste, biohazardous waste, red-bag waste and items such as sharps, blood and body fluids, and laboratory waste products. Also known as red-bag waste.
  • Hazardous chemical waste. Chemicals that may cause or contribute to an increase in serious, irreversible or incapacitating illness; or that pose a substantial present or potential hazard to human or environmental health when treated, stored, transported, disposed of or otherwise managed. HCM is regulated by the Environmental Protection Agency via the Resource Conservation Recovery Act. Also known as yellow-container waste.
  • Recyclable and reusable materials. Any item that can be diverted from landfills or incinerators through recycling or reuse, such as paper, aluminum, food and compost.
  • Solid waste. All waste that is not infectious, hazardous, recyclable or reusable. This is sent to landfills or incinerators, contributing to pollution of ground water and decreased air quality. Also known as clear-bag waste.

Much of what gets tossed into clear bags is recyclable: paper, cardboard, plastic packaging from sterile supplies and so forth. Adding recycle bins to your facility can make a huge difference. Here are simple steps to launch a recycling campaign.

  • Start with what you buy. Paper should be chlorine-free and 30 percent or greater post-consumer recycled. Reduce your purchase of polyvinyl chloride products, which can have harmful effects when used in patient products and can damage the environment when incinerated as medical waste.
  • Introduce separate bins for recyclables to the staff lounge first. This lets staff get in the habit in a more informal environment, even if they're only tossing morning newspapers in the paper bin and soda cans in the aluminum bin.
  • Market your recycling program. Put together a presentation on what you're doing and, more importantly, why you're doing it. Get the facility's administrators on board, too. Our hope was that we could convince our perioperative colleagues to at least try the recycling program - but, much to our delight, the presentation was so well received that everyone jumped on board.
  • Hit the perioperative area. Next, introduce paper and cardboard and plastic bins for pre-op, PACU and the ORs. Our hospital already recycled about 400 tons of cardboard per year, but we stepped up our efforts to keep clean cardboard out of red-bag trash. Stress two main activities with your staff. First, only open necessary supplies and equipment in the ORs. Second, meticulously sort all trash. Remind your nurses that they won't have to make special trips to the bins. Eventually, at some point in every case, they'll have to leave the room to get something - when leaving, they can gather plastic wrappers and drop them in the plastic recycling container right outside the OR door. Our patient care assistants are instrumental in making this project work; they also assist staff in the recycling effort by transporting the plastics and cardboard to the recycle bins when the need arises. In PACU, toss those unused lab slips and requisitions into a recycle bin specifically for paper next to the nurses' station.

A small FYI: No. 1 and No. 2 plastic represent the largest volume of plastic in the OR. They're used for packaging items such as cement systems, staplers and reloads, to name only a few.

  • Educate non-nursing disciplines. Our anesthesia pro-viders were throwing everything in biohazard trash, including saline IV bags and pourable sterile saline and water bottles. The CDC's rule of thumb: You can dispose of items that aren't dripping or saturated with blood and body fluids, even if they've been used in the OR, in the solid waste stream.
  • Who's handling the back end of the program? Whether it's environmental services or a maintenance person, make somebody responsible for providing the bins and routinely emptying them. At our hospital, plastic, cardboard and paper are collected and taken to the service center, where they're baled for pickup by our recycling hauler. We are reimbursee for plastic, but it's just enough to cover the costs of the baling efforts, making the endeavor a break-even proposition. Still, it doesn't end up in a landfill. Since our program began in August, BWH's ORs have baled and recycled about 1.5 tons of plastic - and we're doing more every month.

Doing your part
AORN calls for nurses to conserve supplies, reprocess where possible and recycle in its 2006 position statement on environmental responsibility. The Ameri-can Hospital Association and EPA have joined to form H2E or Hospitals for a Healthy Environ-ment and the movement is picking up momentum. Further, more states are cracking down on institutions that discard of cardboard rather than recycling it. Professionally, ethically, monetarily and practically, you've every reason to get involved and start making a difference.

Thinking Outside the Box (Literally)

Wouldn't it be great if you had less waste to dispose of to begin with? At least one manufacturer is pitching in on that front: Kimberly-Clark has reconfigured packaging for its new Sterling Nitrile, and the changes can reduce exam glove and packaging waste disposal costs for your facility by more than 39 percent on average, says the company.

  • 150 Sterling Nitrile gloves fit in a standard, 100-count-sized box, making it possible to decrease glove storage by 33 percent, freeing up about 2,000 cubic feet per year for other supplies and equipment, as these photos illustrate (left to right: the space taken up by original packaging; the space saved when gloves with the new packaging are put in the same space; and how much more you can then put in that newly freed-up space).
  • More gloves in the box decreases packaging material by 40 percent.
  • If your facility uses 6,000 standard cases of gloves annually, you could reduce your disposal burden by more than 20 tons of medical waste every year.
  • All boxes are fully recyclable, as per the company's 10-year-old landfill-free manufacturing initiative.

"Just from a cost-savings perspective, if you can throw out more than 20 tons less trash per year just by switching gloves, depending on your per-pound rate, you can see a big reduction in spending on disposal," says Lon Taylor, a global product manager for Kimberly-Clark's infection control business.
