Operations & sourcing · Saint-Barthélemy

Less waste.Sourcing done with integrity.

What the world wastes, why a small island feels it first, and what reaches the sea around Saint-Barthélemy. For villas, restaurants, hotels and private estates that want operational excellence without the hidden cost.

1. The world picture

In 2022, the world wasted 1.05 billion tonnes of food — 132 kilograms per person, and almost one fifth of all food available to consumers. Households account for 60% of it, retail for 12%, and food service — restaurants, hotels, catering — for 28%.¹

This is not only a moral question. UNEP estimates that food loss and waste generate 8–10% of global greenhouse-gas emissions.² Every plate that goes back to the kitchen untouched was bought, shipped, stored, cooked and served — and then has to be disposed of.

2. Why islands feel it first

Research on small island developing states finds an average of 2.30 kg of municipal solid waste per person per day, against 1.18 kg in Europe and Central Asia. The same research names six barriers islands face compared with the mainland: limited physical space, lack of capital and financing, vulnerability to extreme events, high operating costs, small markets and diseconomies of scale, and changing norms around reuse and repair.³

UNEP reports that, because of small size, limited disposal capacity and prohibitive export costs, over 80% of mismanaged waste in these states ends up in the ocean.⁴

Saint-Barthélemy is a French overseas collectivity, not one of these states, and it manages its waste far better than that average. But it shares the same physics: every tonne that arrives has to be dealt with on 25 square kilometres, or sent back across the sea.

3. What happens to waste here

Since 2001, the island has turned its waste into energy. The steam produced by incineration goes directly to the neighbouring desalination plant. The operator reports two ovens and 15,000 tonnes of waste treated in 2025⁵, and that the plant can generate a third of the energy needed to desalinate the island's water.⁶

In 2017, the operator at the time described handling 20,000 tonnes a year, of which about half was incinerated; the rest was sorted and shipped to the United States and mainland France.⁷

In other words: on this island, what a kitchen throws away can become part of the water in the tap — and what cannot be burned or composted leaves by boat. Reducing waste at the source is not a gesture. It lowers the load on infrastructure the whole island depends on.

4. The sea around the island

The waters of Saint-Barthélemy lie inside the Agoa Sanctuary, which covers the entire exclusive economic zone of the French Antilles and is dedicated to marine mammals.⁸ The plateau shared by Saint-Martin, Anguilla and Saint-Barthélemy is a breeding zone for humpback whales; from January to May, divers can hear the males sing. Sperm whales and several dolphin species have also been observed in these waters.⁹

Marine debris reaches these animals in two ways. Large pieces are swallowed: in 2012 a sperm whale found dead on the coast of southern Spain was documented as dying from ingesting large amounts of plastic debris.¹⁰ Small pieces arrive through the food chain: a 2022 study in Nature Communications estimated that a krill-feeding blue whale may ingest 10 million pieces of microplastic a day, a fish-feeding humpback about 200,000 — and that 99% of it comes via their prey.¹¹

That study was conducted off California, not in the Caribbean. We cite it for the mechanism, not as a measurement of local waters.

5. What the discipline covers

Operations and sourcing is offered as its own engagement, or as part of a wider diagnostic. It works on four fronts:

1. i.Waste reduction. Audit menus, prep flows and inventory to remove avoidable loss — less food waste, less overproduction, fewer hidden margin leaks across the season.
2. ii.Standardization as models. Repeatable menu architecture, prep stations and service rhythms, so excellence does not depend on who is present in a given week.
3. iii.Fair & ethical procurement. Sourcing relationships built on transparent pricing, honest contracts and respect for producers and intermediaries upstream.
4. iv.Supply-chain integrity. End-to-end design that respects island logistics, seasonal realities and every link in the chain — from producer to plate.

Built by someone trained formally in Business Excellence and Supply Chain Management, and Carbon Literacy certified. Operational rigour and ethical standards are not in tension here. They are the same discipline.
