Reduce Catering Food Waste Before, During and After Events
Share
Reduce catering waste by measuring what was produced, served and left over for each event. Separate production loss from unserved food and plate waste. Those categories answer different questions and should lead to different changes in purchasing, portioning or service.
Before the event: make assumptions visible
Start with confirmed attendance and the agreed service style. Record expected portions per guest, menu mix and any contingency allowance as explicit planning assumptions. Keep a record of late guest-count changes so overproduction is not incorrectly attributed to the kitchen.
Compare ingredient requirements with usable stock before ordering. Confirm that planned quantities fit approved preparation, holding and transport capacity.
During service: count what actually leaves the kitchen
Record trays or portions sent to service and replenishments. Keep unserved reserve food distinct from food returned from display so authorized staff can evaluate its actual handling history. Do not assume food is suitable for reuse or donation simply because it looks untouched.
At breakdown: use a short waste log
- Event, dish and quantity, using a consistent unit such as portions or kilograms.
- Category: prep loss, unserved overproduction, service return or plate waste.
- Verified reason, such as guest-count change, poor demand estimate or damaged packaging.
- Food cost basis and authorized disposition under the approved procedure.
Example: a banquet with excess portions
If 30 portions remain after a banquet, record which dishes remain and whether fewer guests attended or guests chose other menu items. A full waste bin alone cannot distinguish a guest-count problem from a menu-mix problem.
Review unserved portions per guest and food cost wasted per event against similar bookings. Trial one change, such as reducing a low-demand dish's planned share. Never extend holding periods or retain unsafe food to meet a waste target; donation and reuse need their own applicable safety checks.
