Plastic Pollution: A Growing Threat to Patient Health & Sustainable Healthcare

The routine act of providing care—from a simple office visit to complex surgery—generates a significant amount of waste, much of it plastic. Increasingly, healthcare professionals are recognizing that this waste stream isn’t just an environmental concern, but a public health issue with downstream effects on patient wellbeing. A growing body of evidence links plastic pollution to chronic diseases, and current disease management practices often exacerbate the problem. Addressing this requires a fundamental shift in how we approach clinical practice, integrating waste reduction as a core component of patient care.

The sheer volume of waste produced by the healthcare industry is staggering. The U.S. Healthcare system alone disposes of approximately 14,000 tons of waste daily, with 25% of that being plastics. This equates to roughly 7 million pounds of plastic discarded each day, contributing significantly to greenhouse gas emissions – approximately 9% of the nation’s total, and 27% of global emissions attributable to healthcare despite serving only 4% of the world’s population. Medical equipment production, transportation, use, and disposal account for 70% of these emissions.

The Intertwined Crises of Climate Change and Plastic Toxicity

The issue isn’t simply about volume; it’s about the inherent toxicity of plastics and their connection to broader environmental crises. Climate change and plastic toxicity are increasingly viewed as interconnected elements of a “polycrisis.” Healthcare is deeply involved in both, both as a contributor and as a responder to the health consequences. The reliance on plastics in modern medicine, while enabling advancements like dialysis, has also created a dependence on materials derived from fossil fuels and petrochemicals. The plastics industry is on track to triple production, potentially surpassing emissions from coal.

Recycling: A Limited Solution

For years, recycling has been presented as a solution to mitigate the environmental impact of plastic. Though, the reality is far more sobering. In the United States, only about 5% of plastics are actually recycled. The vast majority ends up in landfills, as litter, or is incinerated, releasing toxins into the air. Even “red bag” or biohazardous waste is often incinerated. Plastics don’t biodegrade; they break down into microplastics and nanoplastics, persisting in the environment for hundreds, even thousands, of years. Dialysis waste, for example, will remain in some form for generations.

The Health Effects of Plastic Exposure

Microplastics and nanoplastics have now been found everywhere on Earth, and alarmingly, within every organ of the human body. Research is rapidly uncovering the health consequences of this pervasive exposure. Many plastics contain chemicals known to be carcinogens, neurotoxins, and endocrine disruptors. Studies are increasingly linking plastic pollution to a range of chronic diseases, including cancer, asthma, diabetes, obesity, autism, neurodevelopmental disorders, infertility, heart disease, and adverse pregnancy outcomes.

Specifically, increases in kidney disease, benign prostatic hyperplasia, and bladder and testicular cancers have been associated with plastic exposure. A 2025 study published in The Lancet reported that the number of adults living with chronic kidney disease has more than doubled since 1990, reaching nearly 800 million worldwide, prompting researchers to investigate the role of plastic exposure. A meta-analysis by O’Callaghan and colleagues, also published in 2025, linked increased plastic pollution with the rise in kidney disease, highlighting the “rapidly emerging threat of microplastic contamination within the human urinary tract” and the potential for cytotoxic effects, inflammation, and disruption of cellular signaling pathways.

Practical Steps Towards Reduction

Recognizing the problem is the first step. Sustainability teams across healthcare are actively exploring ways to reduce plastic consumption without compromising patient care. One significant area for improvement is glove usage. Observational studies have shown that gloves are frequently used unnecessarily. Promoting appropriate hand hygiene practices and implementing “Take Off the Gloves” initiatives can significantly reduce waste.

Other low-hanging fruit includes opting for pill formulations instead of intravenous medications when appropriate, using paper cups for medication and water, and switching to reusable utensils in break rooms. Consideration of the plastic footprint should also be integrated into treatment decisions. For example, when choosing a dialysis method, the environmental impact of different dialysate containers should be factored in – canisters have a greater impact than flexible bags, and storage containers have the least.

Innovations in dialysis, such as at-home hemodialysis with concentrated dialysate or point-of-care peritoneal dialysis fluid generated from tap water using on-demand cartridges, can drastically reduce supply needs. The principle is simple: less plastic consumed overall translates to fewer patients requiring dialysis, and less plastic waste generated.

Beyond Individual Actions: A Systemic Approach

Reducing our reliance on plastics requires a systemic approach that extends beyond individual actions. It demands collaboration between healthcare providers, manufacturers, and policymakers. It requires a re-evaluation of our purchasing practices, a commitment to exploring alternative materials, and a willingness to challenge the status quo.

What can you do? Start by assessing your own practice. Identify areas where plastic consumption can be reduced or eliminated. Advocate for sustainable practices within your institution. Educate your colleagues and patients about the health and environmental impacts of plastic pollution.

The oath we take as physicians compels us to “do no harm.” Ignoring the harm caused by our collective plastic consumption is a breach of that oath. By embracing waste reduction as a core principle of clinical practice, we can protect the health of our patients, our communities, and the planet.
