Improve waste management and recycling
Hospitals can improve waste management and recycling by adopting circular economy principles and reducing, reusing, and recycling materials. Firstly, hospitals should review their waste management processes to ensure that recyclable materials are recycled. This includes establishing clear sustainability criteria for waste management and reinforcing sustainable practices. For example, hospitals can partner with medical device companies to reprocess single-use medical devices instead of discarding them. Implementing reuse and recycling schemes in non-clinical areas, such as food and dining services, can also help tackle the issue of single-use plastics. Hospitals can reduce surgical waste and toxic chemicals, as well as properly dispose of medications to prevent them from ending up in drinking water. Additionally, food waste can be reduced by opting for locally sourced food and collaborating with local organizations to produce compost, which can be used in hospital gardens or shared with local food producers.
Furthermore, hospitals can minimize waste by designing buildings with reduced energy needs and incorporating renewable energy sources, such as solar power and rainwater harvesting. This not only reduces the carbon footprint associated with energy consumption but also leads to long-term financial savings. For instance, the Texas Health Harris Methodist Hospital Alliance in North Texas achieved the highest level of Leadership in Energy and Environmental Design (LEED) certification by constructing a green building that utilizes renewable energy sources.
To further improve waste management, hospitals can also focus on sharing durable assets, such as transportation fleets, buildings, and medical equipment, within their networks. This reduces the need for each hospital to purchase new equipment, lowering overall waste and expenses. By adopting these waste management and recycling practices, hospitals can contribute to environmental sustainability and positively impact the health and well-being of their communities.

Source local, healthy food
Hospitals have long been associated with causing environmental degradation that impacts people's health and well-being. They are the second-most energy-intensive commercial buildings in the United States, contributing 10% of the nation's carbon emissions. However, hospitals can significantly reduce their carbon footprint by adopting simple changes, such as reducing surgical waste, toxic chemicals, and installing renewable energy sources.
One way hospitals can become more sustainable is by sourcing local, healthy food. This can be achieved by partnering with local organizations like The Common Market, which offers a variety of programs to integrate local food into hospitals. By purchasing wholesale from The Common Market, hospitals gain access to a range of seasonal produce, including hydroponic lettuces, whole grains, flours, rice, and a growing selection of dairy, proteins, and value-added products. This not only helps to reduce food waste and the hospital's carbon footprint but also provides patients and staff with healthy, flavorful options.
The benefits of local sourcing extend beyond environmental sustainability. By supporting small and medium-sized farms and ranches in the region committed to regenerative farming practices, hospitals can bring equity to their food service operations. Furthermore, local food initiatives can be used to promote healthy habits beyond the hospital walls. For example, The Common Market's Farm-Fresh Box Program delivers boxes of locally grown fruits and vegetables to hospitals, providing healthcare staff and the wider community with nutritious meals.
Additionally, hospitals can work with local organizations to compost food waste, fueling hospital gardens or other local food producers. This further reduces waste and encourages the adoption of sustainable practices. Lankenau Medical Center in Wynnewood, PA, for instance, prioritizes the link between diet and health outcomes and works to ensure access to wholesome food for all. Their partnership with The Common Market has resulted in lower rates of diet-related chronic diseases among those who received their fruit and vegetable boxes.
