Buffet control with computer vision
Measure what is served and what is wasted every service
Computer vision and IoT weighing to track what is served and wasted in real time.
How much food do you throw away without knowing?
Without real measurement, buffet waste is invisible until it hits the P&L.
Replenishment by guesswork
You replenish by routine or when you see the tray is empty. You do not know the consumption rate for each product or the optimal moment to replenish. The result: full trays that end up in the bin.
Unmeasured waste
You know you throw food away, but not how much or which product. Without real data, you cannot act on the root causes. Waste repeats day after day with nobody quantifying it.
Compliance without real data
Food Waste Regulations require measuring and reporting. Today you comply with estimates and manual documents. Without real measurement, compliance is paperwork, not operational.
How the Buffet module works
Hardware + software integrated: computer vision cameras and IoT scales connected to a real-time consumption dashboard with automatic alerts.
Computer Vision per Product
Cameras above the buffet line identify each product on each tray. The system measures fill level, consumption rate and detects when a product is running low or not being consumed.
- Identification per product — it does not measure "total line weight" but how much of each specific dish remains. Salad, salmon, fruit: each with its own consumption curve
- Consumption rate — the system learns how quickly each product is consumed by time slot. Data to decide when and how much to replenish
- Real-time dashboard — view the status of each tray from the kitchen or the central office without walking to the buffet
Smart Replenishment Alerts
The system generates replenishment alerts based on real consumption rate, not fixed schedules. Replenish only when needed and in the right quantity. Less waste, a buffet that always looks attractive to the guest.
- Threshold alerts — when a product level drops below the configured threshold, the kitchen receives the alert automatically
- Suggested quantity — the system calculates how much to replenish based on remaining consumption rate and time until buffet closing
- Replenishment history — every replenishment is logged. Data to adjust the next day's initial production
Waste Traceability
Everything left over at buffet closing is weighed and categorized automatically. You know exactly how many kilos of each product were discarded, at what time and at which site. Actionable data to reduce waste day by day.
- Weighing by category — line waste (leftovers on trays) vs. plate waste (what guests return). Different causes, different actions
- Trends by product — identify which products generate the most waste on a recurring basis. Data to adjust the buffet offering
- Cost of waste — every kilo discarded has an associated cost. The dashboard shows it in euros, not just kilos
Food Waste Regulations Compliance
Food Waste Regulations require measuring, reporting and reducing. Controliza Buffet generates the records automatically with real weighing data, not manual estimates.
- Automatic logging — each buffet session generates a waste record by product, weight and date. No manual intervention
- HACCP reports — documentation ready for audits with full traceability of the production-service-waste cycle
- Benchmark across sites — compare per-capita waste across all sites in the group. Identify best practices and sites that need intervention

The buffet module is not an isolated sensor. Consumption and waste data feed the forecast and purchasing in a closed loop.
Buffet measures real consumption
Cameras and scales record what is consumed, at what rate and what is left over in each buffet session. Granular data by product, time slot and site.
Forecast adjusts production
Real buffet consumption data feeds back into the forecast model. Every day, the forecast becomes more accurate: less overproduction, less waste.
Purchasing orders the right amount
The forecast adjusted by buffet data generates automatic orders with the exact quantity. No over-buying, no shortages. Closed loop.
