The direct impact
Waste prevented before it exists.
The best disposable pack is the one a venue never needs to buy. ReTray keeps a durable container moving through the same simple loop.
The return loop
One container.
Four clear moves.
- 01
Borrow
The venue issues a tagged container and the demo holds a refundable deposit.
- 02
Enjoy
The customer takes their meal without a disposable pack.
- 03
Return
The venue return point marks the container returned and the demo releases the deposit.
- 04
Reuse
The venue washes the container and puts it straight back into circulation.

A return in real life
Maya’s lunch is finished. The tray is not.
Maya brings RT-024 back to Kora Kitchen. In the demo, one scan confirms the return, releases her EUR 3.00 deposit, and sends the container to washing.
For venue operators
Know where the pool stands.
ReTray gives the counter team three useful answers without turning service into a spreadsheet.
Impact you can count
Every return closes the loop once.
No distant estimate. No vague sustainability score. The product action and the environmental result are the same event.
