Most kitchens
cook food.
I cook the food system.

I built Europe's first zero-waste restaurant. A regenerative farmhouse menu in Ibiza. A 1.5°C-aligned menu for COP28 delegates. Now I'm reshaping the kitchens of the hospitality groups, festivals and wellness brands that are ready to lead the food transition — not narrate it.

The Premise

The food system is the biggest climate lever no one is pulling. Chefs are the only profession with their hands on it every single day.

For thirty years, sustainability in hospitality meant a recycled menu card and a paragraph about provenance. I wanted to know what would happen if you ran a kitchen as if the planet were actually on the pass — not as a side project, but as the whole brief.

So I started building working prototypes. Europe's first zero-waste restaurant in Notting Hill. A regenerative farmhouse menu in Ibiza, sourced from growers within four kilometres. A 1.5°C-aligned menu cooked for COP28 delegates. And now MOANA — the working consolidation of a decade of arguing.

The point is never the building. The point is the proof. Restaurants are the most public lab we have for what people will accept on a plate. Change the plate, and you change demand. Change demand, and you change the field.

MOANA.

Partner · Investor · Head Chef & Culinary Concepts

My current operating home. At MOANA I sit on three sides of the table at once — equity partner, investor, and the chef in the kitchen building the culinary concept from the ground up. It's where everything I've argued for over a decade gets fused into a single working business: regenerative sourcing, whole-plant cookery, ocean-aware seafood, climate-aligned menu architecture — and a guest experience that doesn't lecture, it just lands. This is the model I'm now scaling.

Tiny Leaf ↗

Europe's first zero-waste, organic, plant-based restaurant. Notting Hill. Four floors — bistro, fine-dining room, cinema and events space, botanical cocktail bar. Menus rewritten each morning from would-be-waste deliveries.

50 tonnes of food surplus diverted from landfill in year one.

Founder · Concept → Catering

SATIVA

Originally conceived as a circular-economy vertical-farm restaurant at London's King's Cross — grow on site, generate its own energy, feed waste back into the system. The restaurant itself was never built. The concept evolved into a sustainability-led catering business that carries the same closed-loop principles into other people's events, venues and brand activations.

From concept restaurant to working catering business — the principles survived the pivot.

Can Mimosa ↗

A farmhouse restaurant in Santa Gertrudis, Ibiza. I built out the kitchen garden, partnered with regenerative growers and artisans within a 4 km radius, and rebuilt the menu around the seasonal rhythm of the island. A model for what hospitality looks like when it's local-first by structure.

Farm-to-table, but redrawn — the farm is the kitchen, the kitchen is the field.

Head Chef

FIELD by Fortnum & Mason ↗

Heritage institution, contemporary mandate. Running the kitchen at Fortnum & Mason's sustainability-led restaurant — taking the principles I've spent a decade proving in independents and embedding them inside one of Britain's most recognised hospitality brands.

Field to fork to future.

Climate-Conscious Catering · 2023

COP28 — A 1.5°C Menu

Worked on the Climate Conscious Catering initiative launched at COP28: building 1.5°C-aligned menu options for delegates. Tasty. Nutritious. Climate-honest. Proof that the world's most-watched sustainability summit can actually eat like the future it negotiates.

Notting Grill ↗

A food channel built with filmmaker Phil Sansom. The kitchen as a content platform — refusing the default, on camera. Recipes, provocations, and the working backstage of a sustainable practice. Follow along on @nottinggrill.

The Manifesto

Five things I'm willing to argue about.

  1. Waste is a design flaw — not a fact of cooking.
  2. The kitchen is the most underused climate lever we have.
  3. Plant-forward isn't deprivation. It's the future of pleasure.
  4. Wellness without ecology is theatre.
  5. If hospitality won't lead the food transition, it gets left behind by it.
Work With Justin

Three ways I show up. All of them deliver.

01

Keynotes & Festival Programmes

Headlining stages on food, climate, regenerative agriculture and the new wellness economy. Punchy, evidence-led, made for festivals that want a chef who can argue the case — not just plate the canapés. Closing keynote, panel chair, demo plus talk, or a curated dinner-as-keynote.

For: sustainability festivals · wellness summits · industry conferences
02

Hospitality Consultancy

For hotel groups, restaurant brands and wellness retreats ready to actually move. Holistic menu design, supply-chain redesign, zero-waste kitchen build-outs, regenerative sourcing strategy, and the operational change-management that makes any of it stick. Retainers, residencies, transformation projects.

For: hotels · restaurant groups · wellness brands · resorts
03

Signature Residencies & Climate-Conscious Catering

From a COP-grade 1.5°C menu for 500 delegates to a season-long residency at a wellness retreat. Pop-ups, takeovers, launch dinners, retreat partnerships and event catering — all built around the regenerative supply chain, with the storytelling that gets the press to show up.

For: brands · summits · retreats · launches · private clients
In Their Words

The case, on the record.

"Change people's perception of what waste is, and then we can change how much waste we create."

Justin Horne — Hospitality Interiors ↗

"Vegetarian cuisine is a great medium — I don't think they're always given their place. There's no reason why you can't make something amazing out of vegetables alone."

Justin Horne — on Tiny Leaf ↗

"Through a more conscious approach to eating we can change our behaviour and sustain the planet and the human race."

Justin Horne — Scoolinary ↗

"Founder of the first zero-waste, organic, plant-based restaurant in Europe, and specialist in holistic menu design."

Scoolinary — Chef Profile ↗
