Key takeaways
- Waste is a planning problem before it is a plate problem.
- Measure it — what is weighed gets managed.
- Portion control and batch cooking deliver quick wins.
- Good waste practice supports ESG reporting.

Safe handling of surplus food
Surplus from the serving line should only be reused or donated where food-safety rules allow, with correct temperature control. Never compromise safety for savings.
