Canteens cook by guesswork.
Bins get weighed, but a bin can’t tell you which dish came back or who didn’t eat. Without that, kitchens over-order, plates come back full, and the cycle repeats.
of food was thrown away in Singapore in 2023. Only about 18% was recycled.
of the world’s food waste comes from food service: canteens, restaurants and caterers.
of global greenhouse gas emissions come from food that is lost or wasted.

One scanner. Two scans.
Look at the camera and put your tray down before you eat, then again after. The AI sees which dishes you had, how much of each you ate and the nutrients in it, in about two seconds. Nobody types anything or carries a card.
The AI recognises each dish on the tray: rice, chicken, kailan, soup, fruit.
Grams served, grams left and grams eaten, for every dish and every person.
Energy, protein, carbs, fat, fibre and sodium actually eaten, plus food groups against My Healthy Plate.
A proven method: research systems that scan trays before and after the meal with a depth camera identify about 89% of foods, and their nutrient estimates closely match the real values (Pfisterer et al., JMIR Aging 2022; Lu et al., 2020).

Loopi
A virtual pet that only eats the lunch you really ate. Less waste keeps it healthy and levels it up. Food groups, not calories, plus challenges and a class race.

Loopi Care
Every meal measured, no food charts. Patients choose tomorrow’s meals, and after a poor meal the nurse sees the alert with their reason.

Loopi Work
A health goal becomes a daily canteen pick. Pre-order to skip the queue, and a 3 pm check-in shows which lunches leave you flat. Private by default.

Every step has a way out.
A queue of hungry students can’t wait for a stuck machine. We walked through every step, found where it breaks, and fixed it. You can try each one in the kiosk demo.
“We couldn’t find you.” Try again, or type a class and register number.
Students can switch it off in the app; the scanner goes straight to the keypad.
The scale waits for hands off, then measures again by itself.
A regular portion is used as the estimate and marked “estimated”.
Students are compared with their own usual; a small plate finished scores full marks.
Consent on day one. Only grams per dish and a tray number leave the scanner.
Measuring waste cuts it.
Caterers that started measuring their food waste cut it by 36% in the first year, with a 6:1 return on what they spent (Champions 12.3: 86 sites in six countries, including Singapore). PlateLoop measures every tray automatically.
Why we expect it: when 86 catering sites in six countries, including Singapore, started measuring their food waste, they cut it by 36% in a year and got a 6:1 return (Champions 12.3, 2018). Our estimate assumes a smaller 30% cut: 190 school days, 25% of food wasted today, S$2.50 of ingredients per meal, 2.5 kg CO₂e per kg of food. To be validated in a pilot.

- Open the kiosk, pick Wei Ling and scan her tray before lunch, then after.
- Open Loopi in another tab: her lunch is in Loopi’s bowl. Feed it, then sweep up what she left.
- Open Kitchen: the tray is in the live numbers, and Purchasing plans tomorrow.
- In Loopi Care or Loopi Work, scan a meal from the demo panel and watch the report change.
