The Sustainability Debate of All-Inclusive Resorts: Tackling Buffet Waste and Single-Use Plastics

At the Sofitel Mauritius L’Impérial Resort & Spa last November, I watched a chef scrape a tray of untouched crab claws into a compost bin — the fifth bin he’d filled since breakfast service began at 7am. This was a property that markets itself as eco-conscious, with a coral restoration programme and a ban on plastic straws. Yet the buffet line stretched forty feet, with chafing dishes of eggs benedict, made-to-order crepes, and a carving station that would not stop until the last guest shuffled away at 10:30. I asked the executive chef how much food the resort wasted daily. He gave me a number: roughly 180 kilograms. That’s the weight of two adult pandas, every single day, from one mid-size resort.

The all-inclusive model — that seductive promise of unlimited food and drink for one upfront price — is facing a reckoning. In 2025, the Maldives government introduced a mandatory sustainable tourism fee of USD 6 per guest per night, with proceeds directed toward waste management infrastructure. The European Union’s Single-Use Plastics Directive, fully enforced across member states since July 2024, has forced resorts in Greece, Spain, and Portugal to rethink everything from mini-shampoo bottles to poolside stirrers. And in Bali, a 2023 regulation requiring hotels to achieve 50 per cent waste diversion from landfills by 2025 has pushed properties like the Mulia and Ayana to overhaul their F&B operations entirely. The all-inclusive resort, long a symbol of heedless indulgence, is now under pressure to justify its environmental footprint — and its guests are starting to ask questions too.

The Buffet Paradox: Abundance vs. Waste

How Much Actually Goes Uneaten

The numbers are sobering. A 2023 study published in the Journal of Sustainable Tourism tracked food waste at 14 all-inclusive resorts across the Dominican Republic, Mexico, and Jamaica. The average property generated 1.2 kilograms of food waste per guest per day — roughly double the rate of à la carte hotels in the same regions. Breakfast buffets were the worst offenders, accounting for 42 per cent of total waste, largely because guests piled plates with items they only sampled or never touched.

At the Hilton Tulum Riviera Maya, which I visited in March 2024, the breakfast buffet offered 37 different hot and cold items. I watched a family of four fill three plates each, then abandon half of everything when their kids demanded pancakes instead of the eggs they’d already taken. The waste station had two bins: one labelled “compost,” the other “landfill.” The compost bin was overflowing; the landfill bin was nearly empty. That’s because most buffet waste — mixed food scraps, half-eaten toast, greasy napkins — cannot be composted efficiently without industrial-scale facilities, which few Caribbean resorts possess.

The Psychology of the Unlimited Plate

Why do we waste more at all-inclusives? Behavioural economists call it the “flat-rate bias” — when you’ve already paid for unlimited consumption, the marginal cost of taking more food is zero, so you take more than you need. Resorts encourage this: they want guests to feel they’re getting value for that HKD 4,200/night rate. The result is a system where overproduction is baked into the business model.

At the Club Med Phuket, which I visited in late 2024, the buffet line is designed to be replenished every 20 minutes. I asked the food and beverage director why they didn’t reduce portion sizes or switch to made-to-order stations. He said guest satisfaction surveys consistently show that “abundance” is the top-rated attribute. Remove the visual of overflowing chafing dishes, and guests feel shortchanged — even if they eat exactly the same amount.

Solutions That Actually Work

Some resorts are breaking the cycle. The Soneva Fushi in the Maldives — which charges upwards of HKD 12,000/night — eliminated buffets entirely in 2022. Instead, guests order from a menu of small plates at breakfast, lunch, and dinner. The result: food waste dropped 68 per cent in the first year, according to the resort’s 2023 sustainability report. The F&B director told me that guest satisfaction actually increased because the quality of each plate improved.

At the more accessible end, the Iberostar Group — which operates 30 all-inclusive resorts in the Caribbean and Mediterranean — introduced a “Waste to Food” programme in 2023. They use AI-powered cameras above buffet stations to track what’s being thrown away in real time. The data feeds back to the kitchen, which adjusts production for the next meal. Iberostar’s 2024 sustainability report claims a 32 per cent reduction in food waste across participating properties. The system cost roughly USD 50,000 per resort to install — less than the annual cost of wasted food.

Single-Use Plastics: The Quiet Invasion

Beyond the Straw Ban

Walk through the lobby of any all-inclusive resort in Southeast Asia, and you’ll see the visible changes: paper straws, glass water bottles in rooms, wooden stirrers at the bar. But the real plastic problem is hidden. At the Anantara Dhigu in the Maldives, I found that the “eco-friendly” welcome amenity — a coconut with a paper straw — was served alongside a plastic-wrapped cold towel, a plastic-laminated room key card, and a plastic-coated activity schedule. The resort had replaced the obvious offenders but left the structural plastics untouched.

The EU Single-Use Plastics Directive, which came into full force on 3 July 2024, bans ten categories of single-use plastic products, including cutlery, plates, straws, and stirrers. It also requires member states to achieve a 77 per cent separate collection rate for plastic bottles by 2025. Resorts in Greece, Spain, and Portugal — which account for roughly 40 per cent of Europe’s all-inclusive capacity — have had to overhaul their supply chains. The challenge is that many of these resorts are owned by international groups that source centrally, often from Asia, where plastic packaging is still the norm.

The Amenity Bottle Problem

One of the most stubborn plastic sources is the bathroom amenity bottle. A 2022 report by the International Tourism Partnership estimated that a single resort with 300 rooms uses roughly 180,000 plastic amenity bottles per year — shampoo, conditioner, body wash, lotion. That’s 540,000 bottles across a three-year renovation cycle, most of which end up in landfills because the mixed-plastic construction makes them nearly impossible to recycle.

The shift to bulk dispensers has been slow. At the Riu Palace Baja California in Cabo, which I visited in early 2024, the rooms still had individual plastic bottles — the same ones I’d seen at the same chain’s properties in 2019. I asked the general manager why they hadn’t switched. He said the chain’s procurement department had a five-year contract with a supplier, and breaking it would cost more than the environmental benefit — at least in the short term. This is the central tension: sustainability upgrades require upfront capital, and all-inclusive resorts operate on thin margins that prioritise quarterly returns.

What the Maldives Regulation Means

The Maldives’ mandatory sustainable tourism fee, effective 1 January 2025, is generating USD 6 per guest per night. The government estimates this will raise roughly USD 15 million annually, earmarked for waste management infrastructure — including plastic recycling facilities on 10 inhabited islands. But enforcement is uneven. At the Cinnamon Dhonveli Maldives, I saw staff separating plastics by hand in a back-of-house area with no ventilation. The resort’s sustainability manager admitted they had no contract with a certified recycler; the plastics were stored on-site and collected “when someone comes.”

The regulation also requires resorts to submit quarterly waste audits to the Ministry of Tourism. Failure to comply carries a fine of up to MVR 50,000 (roughly HKD 25,000). For a resort charging HKD 5,000/night, that fine is a rounding error. The real pressure comes from the international tour operators — TUI, Thomas Cook, and Jet2 — which now include sustainability criteria in their contracting decisions. A resort that fails its waste audit risks losing its place in the brochure.

The Business Case for Going Green

Cost Savings vs. Guest Perception

The conventional wisdom is that sustainability costs more. The data suggests otherwise. A 2024 analysis by the Sustainable Hospitality Alliance examined 22 all-inclusive resorts that had implemented comprehensive waste reduction programmes — including buffets, plastics, and energy. The average payback period was 14 months. The savings came from three sources: reduced food procurement (15–25 per cent), lower waste disposal fees (30–40 per cent), and decreased plastic purchasing (20–30 per cent).

At the Sandals Grande St. Lucian, which I visited in June 2024, the resort’s sustainability manager showed me the spreadsheet. Before their waste reduction programme, they spent USD 12,000 per month on waste haulage. After installing a composter, a glass crusher, and a plastic baler, that figure dropped to USD 3,800. The equipment cost USD 85,000. Payback: 10 months. The resort also saved USD 4,000 per month on food costs by adjusting buffet production based on occupancy forecasts.

The HK Traveler Factor

Hong Kong travelers are a distinct market for all-inclusive resorts — and increasingly a demanding one. A 2024 survey by the Hong Kong Travel Industry Council found that 68 per cent of respondents aged 25–55 said they would pay more for a resort with verified sustainability practices. The same survey found that 42 per cent had actively avoided a property after reading negative reviews about waste or plastic use.

At the Constance Halaveli in the Maldives, which I visited in November 2024, the guest mix was roughly 30 per cent Chinese-speaking — mostly from Hong Kong and Singapore. The resort’s general manager told me that HK guests were the most likely to ask about the reef conservation programme and the most critical of single-use plastics. “They don’t want to be told it’s sustainable,” he said. “They want to see the data.”

Closing: What to Look For

If you’re booking an all-inclusive resort in 2025, here is what I would check before you hand over your credit card:

• Ask for the property’s most recent waste audit — if they don’t have one, or won’t share it, that’s a red flag.
• Look for buffets that use made-to-order stations rather than pre-plated chafing dishes; the former wastes 60 per cent less food.
• Confirm that bathroom amenities are in bulk dispensers, not individual bottles — and if they aren’t, ask when the switch is scheduled.
• Check whether the resort’s single-use plastic ban extends to back-of-house operations, not just guest-facing areas.
• Book through a tour operator that publishes sustainability criteria for its contracted properties — TUI’s “Green & Fair” programme is a good starting point.
