The Ohio State University Wexner Medical Center is committed to being a responsible steward of our resources through efficient operations, innovative research and ideas and to “first, do no harm.” Great health starts with a healthy environment, which is why the wellbeing of our patients, employees and community members inspires us to work harder. From waste to energy to the food we serve, we have a responsibility to demonstrate health in our operations.


Sustainability Goals

All of our sustainability efforts align with our Strategic Plan and The Ohio State University’s resource stewardship goals. The progress toward sustainability initiatives at the medical center is extraordinary and this page only captures a small sample of the outstanding work and our successes.

FY21 Sustainability Report


Sustainability Program: Waste

Hospitals produce an average of 29 pounds of waste per patient stay. Health care’s complex waste stream is also expensive, with regulated medical waste costing 10 times as much as solid waste. The medical center is committed to first preventing waste upstream and managing it appropriately through landfill diversion, recycling, composting and ensuring items end up in the correct waste stream.

  • We increased the diversion rate to 35% with efforts such as blue sterilization wrap collection expansion, food waste reduction efforts and continued expansion of recycling infrastructure.
  • Reusable sharps container implementation in the last quarter of FY21 already prevented 7.5 tons of plastic from going to the landfill.
  • In fiscal year 2021, the medical center diverted 145 tons of pre-consumer food waste by using a digester (a machine that converts food to a liquid that drains to a wastewater line), donated 11 tons and composted two tons of pre-consumer food waste, which resulted in a total of nearly 160 tons of food diverted from landfills.

Sustainability Program: Energy

Per Energy Star, hospitals use about two and a half times more energy per square foot than an office building of the same size. From research, we know that emissions from fossil fuels are linked to a multitude of health conditions — which is why the Ohio State Wexner Medical Center is working to improve energy efficiency and transition to more renewable energy sources.

  • In partnership with the Ohio State Energy Partners, we’re continuing to complete the LED retrofit, began construction on energy conservation measures and finished installation of smart meters.
  • In fiscal year 2021, approximately 16% of the electricity supplied to the medical center at main campus and 100% for off-site medical center locations was carbon neutral through the use of renewable energy credits.
  • The Building Automation System team worked to institute scheduled setbacks in multiple buildings, leading to significant energy savings, such as at McCampbell Hall with a nearly 30% decrease in energy use intensity.

Sustainability Program: Greening the OR

According to Practice Greenhealth, operating rooms drive up to 60% of a hospital’s revenue while producing more than 30% of a facility’s waste and two-thirds of its regulated medical waste and consuming nearly three to six times more energy per square foot than anywhere else in the facility. The Ohio State Wexner Medical Center formed a Greening the OR task force to look at best practices and implement new procedures to improve efficiency and reduce waste.

  • One goal of the task force was to lower the environmental impact of gases associated with anesthesia, with a special focus on reducing the use of the anesthetic desflurane, which has 10 times the global warming potential as sevoflurane, which is a similar alternative to desflurane. The task force achieved a 46% reduction of desflurane across the health system, realizing nearly $300,000 in cost savings over a two-year period.
  • Collection of blue sterilization wrap (used to keep instruments sterile) continued at two new additional OR pavilions in FY21 and has resulted in more than 5 tons diverted from landfills.

Sustainability Program: Sustainable Procurement

Hospitals purchase an enormous amount of goods and services, which presents an opportunity to make sustainable purchasing decisions that positively impact our community and the environment.

  • Since 2011, we have diverted nearly 115 tons of single-use devices from the landfills through a reprocessed medical device program and saved $9 million.
  • We developed sustainable procurement guidelines and integrated sustainability criteria into the request for proposal (RFP) scoring matrix.
  • In fiscal year 2021, 16% of all food purchased by the medical center was sourced locally, thereby supporting local businesses and farmers.
  • In fiscal year 2021, 75% of the medical center’s spending through its group purchasing organization, Vizient, had at least one environmental attribute, such as a product containing forest stewardship certified wood or a plastic that’s recyclable.
  • In fiscal year 2021, the medical center’s Space and Facility Planning and Supply Chain departments partnered together to integrate sustainability criteria into the procurement process for all current and upcoming construction projects.
  • Not only have 80% of all materials installed met the sustainability criteria, but the medical center will also realize immediate cost savings and additional savings over the life cycle of these more-sustainable building materials.

Sustainability Program: Green Building

The Ohio State University launched its new Sustainable Design and Construction Policy in February 2021.

  • All construction projects now incorporate more sustainability elements based on project type, project scope, jurisdiction and budget, and require suppliers to be more transparent around sourcing, material content and the carbon footprint of materials.
  • One exciting example of the impact these standards have already had is the under-construction inpatient hospital that’s diverting 86 million pounds, or 39,000 tons of materials — which translates to 98% of the waste materials being recycled.

Sustainability Program: Employee Engagement and Education

Employees who believe they can make a direct social and environmental impact through their job report higher satisfaction levels, according to a Net Impact survey. Attracting and retaining the top talent in clinical care, research and education is a priority for the medical center. Acquiring top talent allows us to accelerate the pace of discovery, quickly translate research findings into treatments and prevention methods, and ensure that we have well-trained and engaged health care providers in the years ahead.

  • One way for faculty and staff to make a direct impact is through the Green Team, a group of volunteers who support sustainability initiatives throughout the organization. The Green Team was created in 2018 and now has more than 700 employees eager to make a difference.
  • Between January and June 2021, the Ohio State College of Medicine’s student-led Sustainability in Medicine group recruited 120 households with 180 individuals to participate in a composting and recycling program. This initiative diverted 6 tons of recycling and 24 tons of compostable materials from the waste stream in just six months.
  • Over 40 department leaders participate in the Sustainability Council by leading sustainability initiatives within their respective departments and participating in monthly education and information-sharing calls.
  • The Ohio State Wexner Medical Center Green Team hosted an Earth Day event in April 2021 that collected and recycled more than 3,250 pounds of unwanted documents and gave away 150 native sapling trees for employees to plant during activities to celebrate Earth Day 2021. In addition, the Green Team collected 5.3 cubic yards of electronics and 50 pounds of batteries and donated more than 70 pairs of shoes to be recycled. More than 5,800 faculty and staff participated in the “Every Day is Earth Day” Your Plan for Health Challenge, in which they kept track of actions they took for the good of the Earth and their health.
  • In FY21, a group of medical school students, residents, fellows, faculty, deans, sustainability staff and practicing clinicians came together to integrate climate change, health and environmental justice issues into The Ohio State University College of Medicine’s existing curriculum, as well as into professional development offerings for established physicians.
  • Sustainability leaders from the medical center contributed to the growing conversation around sustainability in health care in FY21. Solid Waste Authority of Central Ohio (SWACO) and Waste Today magazine featured Aparna Dial, MS, MBA, LEED AP, senior director for Sustainability and Strategic Services for The Ohio State University and the Ohio State Wexner Medical Center.


Transportation is the No. 1 contributor of the nation’s greenhouse gas (GHG) emissions, according to the U.S. Energy Information Administration. As major employers with complex supply chain logistics, hospitals are wellpositioned to reduce transportation GHGs by influencing employee commutes, transitioning to low- or zeroemission fleet vehicles and optimizing supply chain distribution practices.

  • In FY21, telehealth encounters grew to 369,161 and saved patients nearly 22 million miles driven and 1 million gallons of gasoline, and reduced appointment-related waste by 12 tons and 7,700 metric tons of carbon dioxide.
  • A group of undergraduate students developed a formula to determine that the nearly 500,000 patient telehealth visits since the onset of the pandemic accounted for a reduction of more than 15.8 tons. While the appointment-related waste is primarily small items — exam room table paper sheets, gloves and aftervisit summary documents, it still has a significant aggregate impact.
