What You'll Learn
Flexible portion sizes
Hospitals generate over 30 pounds of waste per bed per day, with 10-15% of an average hospital's waste being food waste. This costs hospitals around £230 million annually in the UK alone. In the US, hospitals spend $0.06 to $0.10 per pound for waste removal, which can be reduced by implementing effective food waste management strategies.
One of the most effective ways to reduce food waste in hospitals is to offer flexible portion sizes. This strategy allows patients to choose the amount of food they receive, reducing the amount of food that goes to waste. For example, UCSF Health has added more made-to-order stations, allowing them to minimise the creation of large quantities of food in advance, which often goes to waste.
Implementing flexible portion sizes can also increase patient satisfaction and reduce food waste. Patients with different nutritional needs and appetites can adjust their portion sizes accordingly, reducing the amount of food left on their plates. This approach has been successful in Lebanese hospitals, where studies have shown that flexible portion sizes can reduce plate waste generation.
Additionally, flexible portion sizes can be combined with electronic ordering systems, allowing patients to choose their portion sizes in advance. This helps hospital staff predict the number of meals they need to prepare, further reducing waste. For instance, Freeman Hospital in Newcastle, UK, introduced a new meal ordering system where patients order 12 hours in advance, resulting in a significant reduction in food waste.
By offering flexible portion sizes, hospitals can reduce food waste, increase patient satisfaction, and improve their environmental impact. This strategy is a crucial step towards more sustainable food service systems in healthcare facilities.

Food donations to food banks
Hospitals generate over 30 pounds of waste per bed per day, with food waste accounting for 10-15% of an average hospital's total waste. This is a significant issue, not only from a financial perspective but also due to its environmental impact. Food waste is the most common material found in landfills, and it accounts for approximately 8% of global greenhouse gas emissions.
One way to reduce food waste in hospitals is to donate excess food to food banks. This strategy, known as "feed hungry people," is suggested by the EPA's Food Recovery Hierarchy, which provides a framework for reducing waste and promoting a circular food economy. The framework includes six levels, with source reduction being the first step, followed by feeding hungry people, then feeding animals, industrial uses, composting, and lastly, the least preferred option of landfill or incineration.
To implement successful food donation programs, hospitals can take several steps. Firstly, hospitals should connect with their food service staff to foster a shared interest in reducing food waste. They can then support these staff members in finding food donation partners within the community. It is also essential to celebrate and communicate the social benefits of the program. Hospitals can also explore ways to report their food donation efforts accurately to showcase their community impact.
By implementing these steps, hospitals can contribute to addressing food insecurity while also reducing their environmental impact and cutting costs associated with food waste. It is a strategy that, when effectively managed, can benefit the hospital, the community, and the environment.

Food waste sorting
The EPA Food Recovery Hierarchy provides a framework to reduce food waste and promote a circular food economy. The hierarchy has six levels, with source reduction being the first step. This involves reducing waste at the production stage, saving resources and reducing emissions. The second step is to feed hungry people, with food banks and donations being a way to divert edible food waste. The third step is to feed animals, though this is subject to regulations. The fourth step is industrial uses, such as generating energy, followed by composting as the fifth step. The last step is disposal methods such as landfill or incineration.
Hospitals can implement strategies to reduce food waste at each step of the hierarchy. For example, flexible portion sizes and made-to-order stations can reduce plate waste. Food donation programs can address food insecurity and reduce waste, though hygiene regulations may pose challenges. Implementing waste dehydration systems or bio-digesters can reduce waste weight and enable water reuse. Additionally, hospitals can improve food purchasing and menu planning to minimise waste and cut costs.
Overall, food waste sorting and reduction in hospitals can have economic and environmental benefits. By adopting sustainable practices and policies, hospitals can contribute to addressing global food waste and climate change issues.

Sustainable food service systems
Hospitals have a responsibility to link human health and the environment, but food waste in hospitals is often much higher than in other areas of the food supply chain. The financial and environmental implications of food waste are significant, and hospitals are in a unique position to reduce their climate impact.
Implementing sustainable food service systems is an important step in achieving sustainability goals and reducing food waste in hospitals. Here are some strategies that can be employed:
Flexible Portion Sizes
One of the most effective ways to reduce plate waste is to offer flexible portion sizes. This allows patients to choose the amount of food that suits their appetite, reducing the amount of leftover food. This can be facilitated by made-to-order stations, where food is prepared in smaller batches, reducing the concept of preparing large quantities of food in advance.
Menu Planning and Food Purchasing
Menu planning and food purchasing offer significant opportunities for waste reduction and cost savings. Hospitals can be smarter about their food choices, taking into account patient preferences, clinical needs, and meal timing to reduce waste.
Food Donation and Diversion
Food donation to food banks and food recovery programs can help feed hungry people and address food insecurity in the community. Hospitals can partner with local organizations to divert edible, unused food to those in need. This strategy is a viable humanitarian and waste prevention approach, although it may be limited by food hygiene regulations and litigious concerns.
Food Waste Repurposing
Implementing culinary education programs can promote food repurposing strategies, such as composting or using food waste to feed animals. For example, some hospitals have installed bio-digesters to recycle and reuse waste and water.
Staff Engagement and Training
Engaging and providing training to food service staff can instill a sense of pride and improve job satisfaction. Staff can be encouraged to contribute creatively to waste reduction efforts and find innovative solutions.
By adopting these sustainable food service systems, hospitals can significantly reduce food waste, lower costs, and positively impact the environment and the community.

Food waste quantification
Another approach is to examine patient plate waste, which refers to the food served but not consumed by patients. This can be done through visual estimation or by weighing plates before and after meals. By understanding the factors contributing to plate waste, such as portion sizes, food preferences, and clinical issues, hospitals can develop targeted strategies to reduce waste. For instance, flexible portion sizes and increased food choices through selective menus can help patients only take what they can eat, reducing waste.
Additionally, hospitals can implement waste tracking systems to monitor food waste generation over time. This involves recording the type and quantity of food discarded, which can identify patterns and areas for improvement. For example, certain food items or meals that are consistently wasted can be identified, and hospitals can adjust their purchasing and menu planning accordingly. This also helps to identify areas where food waste can be repurposed or donated, such as through food banks or animal feed, as outlined in the EPA Food Recovery Hierarchy.
Furthermore, hospitals can also quantify food waste by measuring the environmental impact of their waste generation. This includes calculating the greenhouse gas emissions associated with food waste disposal, such as methane emissions from landfills. By understanding the environmental footprint of their food waste, hospitals can prioritize waste reduction strategies that align with sustainability goals.
Lastly, hospitals can also assess the financial implications of food waste. By calculating the cost of food waste disposal, including waste removal fees and the value of wasted food, hospitals can quantify the economic benefits of waste reduction strategies. This financial data can be a powerful tool for justifying investments in waste reduction initiatives and demonstrating cost savings to hospital administrators.
