The Lodge at Ashford Castle Leads the Way in Food Waste Reduction with Innovative Sustainability Initiatives

Published on July 12, 2025

Sustainability is not merely a fad at The Lodge at Ashford Castle; rather, it is the foundation of the hotel’s operations. The Lodge has successfully cut its food waste by almost 60% by weight in the last year, demonstrating a daring attempt to address one of the hidden issues facing the hospitality sector. The outcomes of this reduction, which is a component of a larger plan to become more environmentally conscious and self-sufficient, are astounding. The hotel has reduced its carbon footprint by almost 50 tonnes by preventing 230,000 pounds of food from going to waste in addition to saving more than €16,000 a year.

The Lodge at Ashford Castle, a 19th-century villa offering opulent lodgings surrounded by Ireland’s lush countryside, is tucked away in the picturesque County Mayo of western Ireland. Its 64 rooms make it a more personal alternative to the nearby medieval Ashford Castle, which is renowned for its majesty and historic charm. What really makes the Lodge unique, though, is its dedication to sustainability and minimizing food waste. A strong supporter of sustainability, Executive Chef Jonathan Keane has spearheaded the hotel’s efforts to drastically cut down on food waste, repurposing what would otherwise be thrown away into useful resources.

The Lodge’s No-Food-Waste Initiative

The Lodge’s “no-food-waste” policy is the cornerstone of its sustainability initiatives. Produce peels, food scraps, and leftover ingredients are no longer thrown away; instead, they are being turned into syrups, canapés, and even welcome drinks for visitors. What was formerly regarded as waste is now essential to giving tourists distinctive and environmentally responsible experiences. In addition to cutting waste, this strategy strengthens the hotel’s dedication to sustainability and adds a creative touch to the dining experience.

The kitchen crew has learned how to turn food scraps into useful ingredients under Keane’s direction, turning what would otherwise end up in the trash into muffins, sauces, and even garnishes. Keane and his team adopted a bold, methodical approach: to identify and address the largest contributors to waste, rather than depending on a variety of small initiatives. They have succeeded in making the kitchen a sustainable model by concentrating on significant improvements.

Technology and Data-Driven Insights

Working with Winnow, a food waste analytics company based in the UK, was a key component of this change. Winnow’s AI-powered solutions track food waste in real time using image recognition technology. This enables The Lodge’s culinary staff to keep tabs on exactly what is thrown out each day and look into the reasons behind it. Keane gets an email every morning with information about the day’s food waste, including pictures of what was thrown in the trash.

For instance, Keane can see exactly what was thrown away and take action to stop it from happening again if two kilograms of onion skins are thrown away. “I get a report every morning that tells me exactly what went into the bin,” Keane says. “I’ll see a picture if two kilograms of onion skins ended up in the trash. After that, I can look into why that occurred rather than those skins being used for stock or another purpose.

The kitchen staff at The Lodge has been able to modify their procedures and repurpose ingredients in previously unthinkable ways by employing data to identify the sources of food waste. The hotel has been able to reduce food waste by 60% in just one year thanks to this data-driven approach, proving that careful management and precise tracking can produce noteworthy outcomes.

The Biodigester and Sustainable Practices

The Lodge has made an environmentally responsible move by implementing a biodigester in addition to upcycling ingredients. This machine turns organic matter into nutrient-rich compost, processing any leftover food waste, no matter how small. The sustainability cycle is then completed by using this compost to fertilize the large gardens that encircle the hotel.

Food waste is just one aspect of the hotel’s dedication to environmental stewardship. Self-sufficiency has been a key priority, and the biodigester is only one component of the larger strategy. The garden project at the Lodge has grown into a major endeavor. Keane and his staff started growing a garden during the pandemic to provide local, fresh ingredients for the hotel’s meals. The ultimate objective is to run a completely self-sufficient system that supplies the hotel with its own herbs, fruits, and vegetables.

A tunnel greenhouse, a distillery with its own orchard, and even an aquaponics system—where fish and vegetables grow symbiotically—are some of the even more environmentally friendly projects Keane has in mind for the hotel. He states, “The long-term goal is to be fully self-sufficient,” highlighting the fact that sustainability is a guiding principle for the hotel’s future rather than merely a temporary project.

Hospitality’s Food Waste Problem

One of the biggest causes of food waste in the world is the hospitality sector. A significant environmental concern, hotels, restaurants, and other hospitality establishments produce over 25% of the 1.3 billion tonnes of food waste produced worldwide annually, according to the UN Environment Programme. A large portion of this waste is dumped in landfills, where it releases the powerful greenhouse gas methane.

Systemic change is necessary to address this problem, and Keane hopes that other businesses in the sector will be motivated by The Lodge’s model. Winnow’s zero-waste culinary advisor Vojtech Végh says, “Once we start measuring food waste, we can then focus on what exactly we need to reduce.” He thinks the industry can drastically cut waste and create a more sustainable and eco-friendly hospitality sector by providing chefs and hotels with data.

A Growing Industry Shift

Other hotels all over the world are starting to embrace sustainability as The Lodge at Ashford Castle keeps setting the standard. Chefs at the Hilton Tokyo have begun using food scraps, such as fruit peels and vegetable trimmings, in soups, desserts, and beverages. Winnow’s AI tools have contributed to a 50% reduction in food waste at Novotel London Excel in recent years, highlighting the industry’s increasing dedication to sustainability.

Initiatives like Yindii are assisting hotels and restaurants throughout Southeast Asia in connecting local diners with surplus food, providing meals at a discount via an app, and avoiding the waste of perfectly good food. Even though they are still in their infancy, these initiatives suggest that the hospitality sector will eventually reduce food waste as a standard procedure.

A Cultural Shift in the Kitchen

According to Keane, sustainability involves more than just procedures; it also entails altering kitchen culture. He asserts that encouraging a positive, accepting environment among the kitchen staff is crucial for long-term success, saying that “sustainability has a lot to do with people.” To build this culture, Keane regularly takes his team out into nature to forage for wild vegetables and mushrooms. These excursions are not only team-building exercises but also reinforce the hotel’s commitment to using local, sustainable ingredients.

Visitors are also encouraged to participate in these foraging excursions, where they will quietly learn about local produce and sustainable practices. Instead of lecturing about sustainability, Keane encourages visitors to get involved and take the lessons with them when they depart.

The Future of Sustainable Hospitality

The Lodge at Ashford Castle is leading the hospitality sector by demonstrating that sustainability can have positive effects on the economy and the environment. The industry as a whole can get closer to a more sustainable future as more hotels adopt eco-friendly operations, self-sufficiency, and food waste reduction strategies. The hospitality sector can set the standard for reducing its environmental impact with sustained innovation, and Keane and his team’s efforts are only the start of a larger movement toward sustainable tourism.
