Tourism Industry Insight: Designing a Lower-Waste Island Stay

At a Maldivian resort, a guest finishes a morning swim and looks for drinking water. A chilled disposable bottle is waiting at the pool bar. The nearest refill point is somewhere near reception, but its location is unclear. The guest takes the bottle. Later, management wonders why its reusable-bottle initiative has achieved less than expected. The guest may support reducing plastic, and the resort may have invested in excellent purification equipment. Yet the decision was made in seconds, at the point of thirst. What would change if the refill were the simplest option?

The hidden price of a free drink

Behavioural economics offers a useful explanation. People choose between options using more than their monetary prices. They also account for walking distance, waiting, uncertainty and effort. Economists call these additional burdens transaction costs. When both drinks are free, even a small inconvenience can determine which one is chosen.

Research on Indian tourists published in 2021 found that inconvenience and established habits were important barriers to carrying reusable water, while environmental beliefs and social norms influenced intentions. That study measured intentions, not actual bottle use at Maldivian resorts. It nevertheless identifies a plausible mechanism: environmental preference can lose to an easier immediate action.

This is a different question from the earlier analysis of how water storage protects resort operations. Having sufficient water in tanks does not guarantee that potable water is accessible where guests need it. The issue here is the final few metres between safe supply and a convenient choice.

Put the refill on the guest’s route

Imagine a resort testing two locations for a drinking-water dispenser. One is inside a corridor near reception; the other is clearly visible between the beach and the pool. The second might attract more refills even if both dispense identical water. That is a hypothesis to test, not a proven improvement.

The relevant measure is not the number of machines installed. It is the proportion of occasions when guests can obtain safe drinking water without making a special journey. A refill point near the gym exit, excursion jetty or restaurant entrance may be more useful than an impressive station nobody passes.

Communication matters at the same moment. The principle behind giving guests information when they can use it applies neatly: a small sign beside a chilled dispenser can answer questions about water quality, cost and bottle compatibility precisely when a decision is being made. Clear maintenance records and reliable treatment are essential; reassuring words cannot replace safe water.

Measure avoided waste, not good intentions

The United Nations Environment Programme has documented hotels replacing disposable water bottles with purified water in reusable containers. Its example from the Philippines demonstrates a practical operating model, not a universal estimate of savings. A life-cycle study of hospitality water packaging in northern Italy also found that environmental comparisons between refillable glass and single-use plastic depend strongly on reuse frequency, transport and recycled content. Material substitution alone is therefore not a reliable environmental scorecard.

For an illustrative 80-guest-night day, avoiding one disposable bottle per guest-night would prevent 80 bottles entering the waste stream that day. Whether this happens must be measured. Operators can track purchased bottles per guest-night, dispenser use, reusable-container losses, washing and treatment costs, guest complaints and packaging actually removed from the island.

The last measure connects with the analysis of how island supply boats can carry more value on return journeys. Prevention reduces the volume requiring collection; better logistics handles what remains. On inhabited islands, the shared-island dividend suggests that jointly maintained refill access might benefit several guesthouses, provided responsibility for water quality and maintenance is explicit.

Back at the pool, the guest has not changed values or received a lecture. The difference is that cold, trustworthy water is now available beside the towel station, and a reusable bottle is already in hand. The disposable option has not necessarily been banned; it has simply lost its convenience advantage.

That is the deeper lesson for tourism operators. Sustainability programmes succeed or fail in thousands of small decisions made during ordinary holidays. Guests should not have to work harder to do the environmentally preferable thing. Design the easy choice well, verify that it is safe, and measure what actually changes. A refill station is infrastructure. A convenient refill is a service.
