Reducing food waste by 2025: an invisible experiment, a collective strategy
June 16 2025In a central kitchen, production starts at 4:30 am. No dish will be sold. No customer will pay for a meal. And yet, every gram produced must correspond to a real, anticipated, consumed need. This is the challenge facing contract catering groups.
In 2025, reducing food waste is no longer an ethical gesture: it's a regulatory, financial and operational imperative. Let's dive into a full cycle, from planning to post-service, to understand how AI, automation and data are silently transforming waste management within a multi-site network.

At the central kitchen, the data speaks before the knives activate
4:45 am. The production manager consults his interface. The day before, the AI modeled the volumes needed for the 12 establishments to be delivered. Quantities are adjusted according to forecasted headcount, past consumption rates, weather and menus. No manual adjustments. Everything is ready to go: weights, recipes, assemblies. Objective: produce just, with no initial waste.
| Key element | Perception terrain | AI processing |
|---|---|---|
| Projected staffing | Absentee feedback table | Crossing of attendance forecast by establishment |
| Daily menus | Entry validated on D-1 | Calculation of historical consumption variances by menu / profile |
| Grammages | Standard scales by age | Dynamic adjustment according to remains observed at equivalent period |
The projection engine runs on a centralized Adoria base (menus, guests, absentees, data sheets). It simulates required quantities and acceptable losses per product, based on actual network data. This planning is refined by an AI model of corrected consumption curves, which integrates the history of non-recoverable waste.
Business objective: Avoid waste upstream of the chain, without degrading quality or regularity. It's an invisible preventive logic, but vital for multi-site groups that produce centrally and then deliver.
In school catering, AI adjusts without interruption
11:28 am. In a school canteen, the first pupils settle in. The hot trays are in place, the quantities prepared follow the planned volumes. But from the very first rotations, an anomaly appears: the vegetable gratin is consumed less than expected. The field teams don't have to react alone. The system has already detected it and proposes a silent adaptation on the following services: reorientation of quantities, change of ration for the remaining classes, escalation of alert to the central kitchen.
| Key element | What the team perceives | What the AI drives |
|---|---|---|
| Take rate hot dish | Less popular dish | Real-time analysis of number of catches vs. forecast |
| Student behavior | Partially filled trays | Correlation with history of similar dish rejection (autumn vegetable gratin) |
| Site reactivity | Kitchen adjustment request | Preparation of a cold supplement available in back-office |
Real-time control relies on interconnection between production module, distribution module and sensors (counting, temperature, post-consumption weighing if present). The AI cross-references distribution deviations with behavioral histories according to age, season, and type of dish. It prevents wider wastage upstream by activating short readjustment loops in the kitchen or internal logistics.
Business objective: Reduce waste at the key moment: that of consumption. Rather than identifying losses a posteriori, AI enables immediate regulation, adapted to the reality on the ground, without overloading teams. This is the key to achieving 2025 targets without cutting back on perceived quality or menu diversity.
It's all about the quality of the food.
Collective catering: turning data into sustainable action
What we throw away today is often the result of a decision made 10 days ago. To act effectively, we need to gain control of flows, forecasts and uses. That's what the Adoria platform is all about: offering you a clear, unified and automated vision of your operations.

After service, AI debriefs, learns and anticipates
2:10pm. Calm has returned to the schools. Service teams tidy up, leftovers are sorted, weighed, thrown away or recycled according to protocols. For the agents, the day is almost over. For the AI, it's just beginning. She collects, analyzes and cross-checks all the day's data: volumes served, leftovers found, rate of return per dish, discrepancies between expected and consumed. Less than two hours later, a summary report is sent to production management.
| Element analyzed | Data collected | AI interpretation |
|---|---|---|
| Rest tray | Average weight per platter at end of service | Rejection rate per recipe → ranking of over/under-consumed dishes |
| Expected/served variance | Theoretical vs. actual quantity per delivery point | Adjustment of projection coefficients for J 7 |
| Seasonality and preferences | Consumption by segment (age, site, menu) | Automatic recalibration of upcoming menus and alerts on dishes with low palatability |
The AI module exploits weighing data (automatic or manual), volumes served from the Adoria production module, and menu/consumption histories. Deviations are modeled as coefficients of variation, which the engine feeds back into the preparation of the next cycle. Restitutions can be visualized in a Power BI dashboard connected to Adoria, or integrated into an automated report sent to site referents and production management.
.
Business objective: Learn from each department. Far from simply taking a snapshot of waste, AI turns every day of production into an iteration. This automated feedback process is the key to piloting network-wide waste, without analysis effort or administrative overload.
Collective intelligence, at the service of every gram avoided
In 2025, the fight against food waste can no longer be won with goodwill and Excel spreadsheets. It is played out on a network scale, in the finesse of invisible adjustments, in the ability to make one day's data speak for itself to better produce the next.
What AI brings to foodservice groups is not a miracle solution. It's a foundation of automation, prediction and continuous learning, capable of:
- Reduce upstream volumes at risk, without impacting the offer or nutritional commitment
- Adapt in real time what is served to what is actually expected
- Capitalize on each day to refine the next cycle, site by site
Environmental performance then becomes a logical extension of operational performance. And this is precisely where the paradigm shift takes place: waste is no longer a cost to be borne, it's a business signal to be exploited.
Environmental performance then becomes a logical extension of operational performance.
