How Can Medical Professionals Reduce Dialysis Waste and Its Impact on the Environment?


Doctors, Patients Want Options to Reduce Dialysis Waste Adding to Climate Change

Dialysis, a life-saving therapy for patients with kidney failure, generates a significant amount of medical waste, contributing to environmental pollution. Recognizing this growing concern, nephrologists and patients are advocating for sustainable kidney care practices to reduce the environmental impact of dialysis.

Understanding the Waste Generated by Dialysis

Dialysis involves removing waste products and excess fluid from the blood. The process uses large amounts of water, energy, and disposable plastic supplies. Each dialysis treatment can generate up to 500 liters of wastewater, along with plastic tubing, bags, and other single-use items.

Waste Disposal and Its Environmental Impact

Currently, there are no established recycling programs for dialysis waste in Canada. Biohazardous waste, including blood-contaminated tubing, is autoclaved and shredded before being landfilled. This disposal method consumes energy and contributes to greenhouse gas emissions.

Additionally, patients on home dialysis often face challenges disposing of their waste. Limited recycling options and the need for extra garbage bags add to their financial burden and environmental concerns.

Nephrologists Advocate for Change

Recognizing the urgent need to address dialysis waste, the Canadian Society of Nephrology has formed a sustainability committee. The committee aims to develop a carbon footprint calculator to measure the environmental impact of dialysis and promote sustainable practices.

“We need a redesign of the systems we’re using in kidney care,” said Dr. Caroline Stigant, a nephrologist and inaugural chair of the committee. “It’s not just for nephrologists, but for administrators, funders of the system, patients, and industry as well.”

Reducing Waste through Prevention and Innovation

Nephrologists emphasize the importance of promoting healthy living to prevent kidney diseases and reduce the need for dialysis. Early diagnosis and access to kidney transplants can also help reduce dialysis dependence.

Innovative approaches to waste reduction include developing biodegradable or reusable materials for dialysis supplies. Researchers are also exploring ways to purify wastewater and minimize the use of single-use plastics.

Patient Perspectives on Waste Reduction

Patients undergoing dialysis express concern about the large amount of waste generated by their therapy. “I find the waste embarrassing and costly to deal with,” said Nancy Verdin, a home dialysis patient.

Patients advocate for more recycling options, better waste management practices, and greater involvement in decision-making related to sustainable kidney care.


Reducing dialysis waste is an urgent environmental and societal issue. Through collaboration between nephrologists, patients, and policymakers, innovative solutions can be developed to minimize the environmental impact of dialysis while ensuring access to life-saving treatment for patients with kidney failure. By promoting sustainable practices and reducing waste, we can protect both human health and the environment for generations to come.
