Key takeaways
- Fulfilment sites hit the generator problem and the consumer problem at the same time, which is what makes peak expensive.
- Count one normal week of empties before volume rises; sites commonly underestimate their own generation.
- Collection and equipment capacity is finite and tightens as peak approaches, so asking early costs little.
- Single-size carton lots from one inbound stream may be reusable stock rather than recycling feedstock.
Every autumn, fulfilment operations discover that they need a lot of bulk boxes right now, plus somebody to take away the large number of empties blocking a door. Both are possible. Neither is as easy as it would have been a couple of months earlier.
The two problems arrive together
This is the specific difficulty of peak in e-commerce and third-party logistics: inbound volume rises, which means more empties accumulating, at exactly the moment floor space becomes most valuable and staff have least time. The generator problem and the consumer problem peak at the same time.
A site that has not planned for it ends up paying for emergency clearance while also buying containers at the last minute, in the same week, having spent the preceding weeks losing productivity to congestion.
The calendar that works
| When | Do this | Why then |
|---|---|---|
| July | Count one week of empties | Establishes the real generation rate before volume rises |
| Early August | Ask about collection capacity for September to December | Capacity is easier to find before it fills up |
| Mid August | Ask suppliers about container stock against forecast | More choice of size and grade |
| September | Start regular scheduled collection | Prevents accumulation reaching crisis level |
| October – December | Frequent collection, stock in and empties out on the same visit where possible | Keeps doors and floor space clear |
| January | Post-peak clearance and reconciliation | Returns create a second wave of material |
Why counting in July is the whole thing
Almost every fulfilment site underestimates its own generation of reusable containers. Bulk boxes arrive full and leave flat, so they are invisible in a way that pallets and cartons are not.
One week of counting in a normal month gives you a base rate. Multiply by your expected peak uplift and you have a number you can hand to a supplier, which converts an anxious conversation in October into a plan made in August.
The carton mistake
Single-size carton lots from one inbound programme can be reusable stock, not just recycling feedstock. Baled as old corrugated they are worth little by weight. Sorted and bundled, cartons in a consistent size may find a buyer as cartons.
During peak, when nobody has time to sort, those cartons go in the baler. The fix is not extra labour; it is a decision made in advance about where the receiving team puts them, because they often arrive already separated.
Returns, the January problem
Peak has a tail. Returns processing in January generates a second wave of mixed containers and cartons, often in worse condition and more mixed than the inbound wave. Sites that plan for December and stop are dealing with that one at a difficult time for staffing.
Build January into the schedule in August. Freight is often easier to find after the holidays, and fewer people are competing for the trucks.
