According to research reviewed by Gram, hospitals generate approximately 46 kilograms of waste daily from nutrition support, feeding tubes and IV nutrition, with nearly half being unused formula discarded without use. An observational audit at an Australian tertiary hospital found that almost none of this waste is recycled, costing about $7,400 annually to dispose of and creating 7 tonnes of carbon dioxide emissions yearly. Better waste management could save hospitals $900 per year while significantly reducing environmental impact.
Hospitals generate massive amounts of waste from patient nutrition support, including feeding tubes and IV nutrition, but nobody was really measuring it until now. Gram Research analysis of a major Australian hospital found that nutrition support creates about 46 kilograms of waste daily, with nearly half being unused formula that gets thrown away. The good news? Hospitals could cut waste by 7 tonnes of carbon dioxide emissions per year and save $900 annually just by managing these materials better. This is the first study to really look at this hidden source of hospital waste.
Key Statistics
An observational audit of nutrition support waste at an Australian tertiary hospital in 2026 found that 45.89 kilograms of waste was generated daily, with approximately half consisting of discarded formula.
According to a 2026 hospital waste audit, nutrition support waste disposal costs approximately $7,400 per year at a single major facility, with potential savings of $900 annually through improved waste management.
A 2026 observational study found that nutrition support waste in hospitals creates about 7 tonnes of carbon dioxide equivalent emissions annually, with potential reductions of 7 tonnes possible through better waste management practices.
Research from a 2026 hospital audit showed that each patient receiving nutrition support generates a median of 0.19 kilograms of waste daily, with negligible recycling rates except for cardboard cartons.
The Quick Take
- What they studied: How much trash hospitals create from feeding patients through tubes and IV lines, where that trash goes, and how much it costs to throw away
- Who participated: One major hospital in Australia tracked on a single audit day; the study looked at all patients receiving nutrition support (eating through tubes or IV lines)
- Key finding: Nutrition support creates about 46 kilograms of waste per day at this hospital, with roughly half being unused formula. Almost none of it gets recycled, most goes to landfill.
- What it means for you: If you’re in a hospital receiving tube feeding or IV nutrition, know that hospitals are working on ways to reduce the waste from your care. Better waste management could help the environment and save hospitals money that could go toward patient care.
The Research Details
Researchers spent one day at a large Australian hospital carefully tracking and measuring every piece of waste created by nutrition support, including feeding tubes, formula containers, IV bags, and unused nutrition products. They weighed everything, sorted it by type, and recorded how it was disposed of (landfill, recycling, or other methods). They also calculated how much the hospital spent throwing away this waste and how much carbon dioxide pollution it created.
This was an observational study, meaning researchers watched and recorded what actually happened rather than testing a new treatment or intervention. They created a checklist tool that other hospitals could use to do the same kind of waste audit in their own facilities. The researchers used basic math and statistics to add up the totals and identify patterns.
Nobody had ever actually measured nutrition support waste in hospitals before. Previous studies looked at hospital food waste from regular meals, but ignored the waste from tube feeding and IV nutrition, which turns out to be a significant problem. By measuring it for the first time, this research shows hospitals exactly where waste is happening and gives them a tool to fix it.
This study is a real-world observation from one hospital on one day, which means the results are accurate for that specific situation but might be different at other hospitals. The researchers were careful and systematic in their measurements, which makes the data reliable. However, because it’s from just one day at one hospital, we can’t be completely sure these numbers represent every day or every hospital. The study is honest about this limitation and provides a useful starting point for other hospitals to do their own audits.
What the Results Show
On the audit day, the hospital generated 45.89 kilograms of waste from nutrition support, that’s about as heavy as a large adult. When divided among patients receiving this type of nutrition, each patient generated about 0.19 kilograms (roughly 190 grams or 6.7 ounces) of waste per day.
The biggest surprise was that approximately half of all this waste was unused formula, nutrition products that were prepared but never given to patients. This could happen for many reasons: a patient was discharged, a feeding tube was removed, or the patient’s condition changed. The other half of the waste came from packaging, containers, tubes, and other supplies needed to deliver nutrition support.
Almost none of this waste was recycled. The cardboard cartons from formula boxes were the only materials regularly recycled. Everything else, plastic bottles, bags, unused formula, and medical supplies, went straight to the landfill. The hospital spent approximately $7,400 per year just to dispose of nutrition support waste.
The researchers calculated that this waste created about 7 tonnes of carbon dioxide equivalent emissions per year, that’s the same pollution as driving a car about 17,500 miles. If the hospital improved its waste management practices, they could reduce this by 7 tonnes annually. The study also found that better recycling and waste reduction strategies could save the hospital about $900 per year in disposal costs. While $900 might not sound like much, it adds up when multiplied across thousands of hospitals worldwide.
This is the first study to specifically measure waste from nutrition support in hospitals. Previous research looked at overall hospital food waste or general healthcare waste, but nutrition support was never isolated and studied separately. This research fills an important gap and shows that nutrition support waste is a bigger environmental problem than anyone realized. It also suggests that hospitals have been underestimating their total waste and environmental impact.
The study only looked at one hospital on one day, so the numbers might be different on other days or at other hospitals. Different hospitals use different nutrition products, have different patient populations, and manage waste differently, so results may vary. The study didn’t track what happened to the waste after it left the hospital, so we don’t know the full environmental impact. The researchers also didn’t test whether their suggested improvements would actually work, they just identified opportunities. Finally, the study didn’t include information about patient outcomes or whether reducing waste might affect patient care quality.
The Bottom Line
Hospitals should implement waste audits like this one to measure their nutrition support waste (high confidence). Hospitals should work to reduce unused formula through better planning and communication between medical teams (moderate confidence). Hospitals should increase recycling of packaging materials and explore reusable containers where possible (moderate confidence). These changes should be made carefully to ensure patient safety and nutrition quality remain the top priority.
Hospital administrators and nutrition departments should care most about this research because they manage food and waste. Environmental advocates should care because this shows a previously unmeasured source of hospital pollution. Patients receiving nutrition support should know this is happening, though it doesn’t change their immediate care. Insurance companies and government health agencies should care because waste reduction could lower healthcare costs. People concerned about environmental sustainability should care because hospitals are major contributors to pollution.
If hospitals implement waste reduction strategies, they could see cost savings within the first year. Environmental benefits would accumulate over time, reducing 7 tonnes of carbon dioxide per hospital per year adds up significantly across thousands of hospitals globally. Changes to reduce unused formula might take several months to implement as hospital teams adjust their processes. Long-term benefits would include both financial savings and measurable environmental impact.
Frequently Asked Questions
How much waste do hospitals create from feeding tubes and IV nutrition?
