Hospitals exist to protect and improve health. However, the health care sector is also a significant contributor to environmental waste and greenhouse gas emissions. In the United States, hospitals generate millions of tons of waste annually and consume large amounts of energy and water. In response, many institutions are implementing sustainability initiatives that reduce waste, lower costs, and improve community health outcomes.
Why Sustainability Matters in Health Care
The U.S. health care sector accounts for nearly 10 percent of the nation’s greenhouse gas emissions. Hospitals operate around the clock, relying on energy-intensive equipment, single-use medical supplies, and complex supply chains. These operations produce regulated medical waste, solid waste, and emissions that impact air quality and climate change.
Environmental stewardship aligns directly with the mission of health care organizations. Reducing pollution and conserving resources supports public health, strengthens operational resilience, and can produce significant financial savings.
Examples of Hospitals Leading Sustainability Efforts
The Ohio State University Wexner Medical Center
Ohio State University Wexner Medical Center has implemented a medical device reprocessing program that diverts significant waste from landfills. By reprocessing pulse oximeters, catheters, and other single-use devices through certified vendors, the medical center has diverted approximately 60 tons of waste while reducing procurement costs.
Providence
Providence has adopted systemwide waste optimization tools to track landfill diversion, recycling, and reuse. Several Providence hospitals have reduced landfill waste by up to 50 percent through composting and improved waste segregation programs.
OSF Saint Anthony’s Health Center
OSF Saint Anthony’s Health Center has received recognition for sustainability efforts that include collecting and reusing medical device sensors and expanding recycling programs. These initiatives significantly increased landfill diversion rates while lowering disposal costs.
UCLA Health
UCLA Health has committed to diverting at least 50 percent of its waste from landfills and has reduced total waste generation since 2018. The health system integrates waste reduction with energy efficiency, water conservation, and sustainable purchasing strategies.
Practical Strategies for Hospitals Seeking to Reduce Waste
Hospitals of all sizes can adopt evidence-based strategies to improve sustainability performance.
Establish Baseline Measurements
Tracking waste generation, recycling rates, energy use, and water consumption provides the data needed to identify opportunities and measure progress.
Improve Waste Segregation
Proper separation of regulated medical waste from general waste can significantly reduce disposal costs and environmental impact. Staff education and clear labeling are essential.
Reprocess Eligible Medical Devices
Working with certified reprocessing vendors allows hospitals to safely reuse certain single-use devices, lowering both waste volume and supply expenses.
Expand Composting and Food Waste Diversion
Cafeteria and patient food waste can often be composted rather than sent to landfill, reducing methane emissions and disposal fees.
Invest in Energy Efficiency
Upgrading lighting systems, optimizing heating and cooling operations, and incorporating energy-efficient equipment can reduce operating costs while lowering emissions.
Adopt Sustainable Purchasing Policies
Selecting suppliers that prioritize recyclable materials, reduced packaging, and safer chemical profiles can influence the broader health care supply chain.
Create Interdisciplinary Sustainability Committees
Green teams that include clinicians, administrators, facilities staff, and supply chain leaders can ensure sustainability initiatives are integrated across departments.
Hospitals across the nation are demonstrating that environmental sustainability is both achievable and aligned with clinical excellence. Through waste reduction, energy efficiency, device reprocessing, and responsible procurement, health care organizations can reduce environmental impact while improving operational efficiency.
As the health care sector continues to respond to climate-related risks, sustainability initiatives will remain an essential component of delivering high-quality care and protecting community health.
