A Carton Waste Audit: Where Eggs Actually Break

Breakage Is Attributed to the Wrong Stage

Most breakage is attributed to transport, because that is where it is discovered. The cause is often earlier or later.

An audit that measures at each stage localises the loss and changes the fix entirely.

It takes a week and usually finds that the biggest loss is not where the complaints come from.

The Stages

Grading and packing, pallet building, cold storage, loading, transport, distribution centre handling, store delivery and shelf placement.

Measure breakage at the end of each stage by counting cracked and leaking eggs in a defined sample.

Use the same sample size at each stage so the rates are comparable.

The Measurement

Sample one pallet per stage per day and inspect every egg, or a defined fraction if the volume is high.

Record cracks separately from leaks. A crack found at packing is a different problem from a leak found at the shelf.

Assign the loss to the stage where it was found, then check the previous stage to confirm it was not already present.

Likely Findings

Handling at the distribution centre and shelf placement are frequent hidden losses, because both involve manual handling of individual cartons.

Cold storage losses come from moisture-driven strength loss in the carton, which shows as crushed corners rather than cracks.

Transport losses are usually lower than assumed when the pallet is properly built and restrained.

Fixes Ranked by Payback

Pallet pattern and restraint: cheap, immediate, and often the largest single improvement.

Carton moisture specification: changes the purchase specification, moderate cost, protects the whole route.

Handling training at the distribution centre: cheap and effective where manual handling is the cause.

A stronger carton: expensive and often the last thing needed.

What to Record

Per stage: sample size, cracks, leaks, crushed cartons and the date.

Add the carton lot and the storage duration at each stage. Both explain variation between weeks.

Review monthly. A single audit is a snapshot; the value comes from the trend.

Acting on the Result

Fix the largest stage loss first, then re-audit. Do not fix several stages at once, or the result is unattributable.

If the loss is uniform across stages, the cause is the carton or the egg condition, not the handling.

Report the audit to the carton supplier with the data. A supplier given evidence usually responds with a specification proposal.

Questions Buyers Ask

Where does most egg breakage happen?

Often at the distribution centre and at shelf placement, which involve manual handling. Transport losses are usually lower than assumed.

How should a breakage audit be structured?

Measure at the end of each stage with the same sample size, separating cracks from leaks and recording the carton lot.

Why separate cracks from leaks?

A crack found at packing is a different problem from a leak found at the shelf, and the fixes differ.

What is the fastest payback fix?

Pallet pattern and restraint. It is cheap, immediate, and often the largest single improvement.

What if the loss is uniform across stages?

The cause is the carton or the egg condition rather than handling, which points to the specification.
