Across the globe, healthcare facilities strive to provide high-quality nutrition to patients, yet a substantial portion of this food ends up in the trash. Hospitals around the world are major contributors to food waste.
For instance, hospitals in the U.S. are responsible for a significant amount of food waste, with estimates suggesting that about 10-15% of all food prepared in hospitals is discarded. In the U.K., it has been reported that approximately one in four hospital meals is thrown away, resulting in nearly 100 million meals being discarded each year. This waste represents not only a loss of resources but also a substantial financial burden for the healthcare system.
Key factors contributing to food waste
Patient preferences and dietary restrictions: Hospitals cater to diverse patient populations with varying dietary needs and preferences. However, standardized meal plans often do not align with individual tastes, leading to a significant amount of uneaten food. A study conducted in public hospitals in East Malaysia found that about 36% of the food served was wasted, with patients citing different food preferences as one of the primary reasons for not finishing their meals. This study highlights the disconnect between hospital meal offerings and patient preferences, indicating that a considerable portion of food goes uneaten when meals do not meet individual taste.
Meal timing and interruptions: Hospital routines, such as the timing of medical treatments, tests, and other procedures, often disrupt mealtimes, which significantly contributes to food waste. This issue is particularly prominent because patients might be absent during meal delivery or may have reduced appetite due to the proximity of medical procedures to mealtimes. A study reviewing hospital food waste in the Eastern Mediterranean region highlighted that long intervals between meal ordering and consumption, along with service interruptions, were key factors leading to increased plate waste. These disruptions make it difficult for patients to consume their meals as scheduled, resulting in higher levels of uneaten food.
Overproduction and portion sizes: Hospitals tend to prepare more food than necessary to ensure that all patients receive adequate nutrition. This results in large quantities of food being discarded. A comprehensive review of food waste in hospitals found that overproduction is a significant contributor to this waste, as hospitals commonly prepare extra food to accommodate all patients, including those who might require additional servings or have specific dietary needs.
Innovative solutions: on-site biodigesters
One of the most promising solutions for valorizing food waste in hospitals is the adoption of an on-site biodigester. The solution offers a sustainable way to manage food waste by converting it into valuable resources like biogas, electricity and natural fertilizer, to co-power the hospital. This approach not only reduces the volume of food waste sent to landfills and incinerators, but also generates renewable energy that can be utilized within the hospital, creating a closed-loop system. As every Waste Transformer biodigester is connected online, the hospital receives daily data to understand their energy generation, waste transformation and average CO2 reduction.
This Waste Transformer transforms municipal food waste into clean energy.
At The Waste Transformers, we believe in turning food waste into value. Our on-site biodigester solutions offer hospitals a powerful tool to not only reduce food waste but also contribute to the local environment . As healthcare facilities worldwide continue to seek ways to enhance their operations and reduce environmental impact, an on-site Waste Transformer biodigester will be crucial in achieving those goals.
