Assuming 3 meals a day are eaten by everyone that is over 1.9 million meals a day, estimates of food waste are around 30%, which is usually discharged at sea, the big problem here is fish normally don’t eat hamburgers it is not a natural food source. Pre-pandemic in 2019 29.7 million passengers took a cruise, by 2021 when cruise ships resumed voyages that number had dropped to 13.9 million , still, that equates to approximately 41.7 million meals (based on 3 per day) with an average of ½ pound or 0.22kg waste per meal . Meaning that over 20 million pounds or 9 million kgs of food waste annually, including leftover food, kitchen waste and uneaten food. Below is a list of challenges faced by cruise lines, however, whilst we are focussing on cruise ships remote location hotels in protected habitats also face similar problems, and the solutions discussed are transferable to university campuses, large hotels, theme parks, hospitals and shopping mall food courts to name a few. 1. Overproduction of food leading to waste. 2. Inefficient food storage practices. 3. Lack of proper tracking and management systems for food waste. 4. Insufficient planning and management of food supplies. 5. Poor waste management facilities on ships. 6. Limited waste reduction and recycling programs. 7. Challenges in keeping freshness and quality of food during extended voyages. 8. Varying Portion sizes 9. Incentive structures that prioritize cost savings over sustainability. Overproduction of food leads to waste. Overproduction of food is a significant issue in the cruise ship industry, leading to a substantial amount of food waste. The demand for a variety of food options, buffets and 24/7 availability of food can drive the kitchen staff to prepare more food than necessary. This often leads to overproduction and waste. Furthermore, with many cruise ships sailing for days or even weeks at a time, it becomes challenging to keep the freshness and quality of food. This can result in uneaten food being discarded, contributing to the problem of food waste. Moreover, to keep up with passenger demands, cruise ships tend to stock up on an excess of supplies, which can also result in overproduction and waste. The excess food is often prepared in copious quantities and left uneaten, contributing to the problem of food waste. To combat the issue of overproduction and reduce food waste, cruise ships can adopt better inventory management systems and implement planning and preparation practices considering the actual demand for food. Additionally, ship operators could implement training programs for kitchen staff to reduce food waste, improve food efficiency, and establish partnerships with local organizations to donate excess food to those in need.
