Reusable bottle guide
Reusable-bottle sorting and quarantine before washing
Reusable-bottle washing should start before the machine. Returned bottles need sorting, quarantine and reject rules so damaged, unknown-history or out-of-scope containers do not consume washing capacity or create avoidable safety and quality risk.

Key questions answered on this page.
Use these answers to prepare a clearer bottle-washing enquiry before machine selection.
Which returned bottles should be separated before washing?
Returned bottles should be separated when their source, previous contents, damage, closure, label system or contamination level could change the washing result. Sorting before washing protects the process from bottles that are not recoverable or need a different route.
- Broken, chipped or cracked glass
- Unknown previous contents or chemical contamination
- Excessive soil, foreign objects or heavy dried residue
- Unsupported bottle sizes, neck openings or base shapes
- Labels or adhesives known to require a separate removal stage
How should quarantine be used in a reusable-bottle process?
Quarantine should hold bottles whose condition cannot yet be accepted or rejected. The decision might depend on inspection, sample washing, label-removal testing, chemical review or confirmation from production. Quarantine prevents uncertain bottles being mixed into the main recoverable population.
- Create a physical quarantine area
- Label the reason for quarantine
- Record source, date and bottle family
- Decide who can release, rewash or reject the bottle
- Keep quarantine samples out of the normal clean-bottle stream
Useful infeed information includes crate or pallet presentation, manual or conveyor loading, bottle orientation, expected reject percentage, bottle family range and whether labels are removed before or after sorting. The handling route should suit real returns, not only perfect sample bottles.
- Incoming container method
- Operator sorting position
- Reject bin or recirculation route
- Label-removal order
- Bottle accumulation before washing
- Inspection point after washing
How to use this guide in a bottle-washing project.
Use the guide to prepare information for discussion; final machine suitability still depends on bottle samples, site services, safety review and the agreed scope.

Keep uncertain returns separate from accepted bottle flow
Create a simple decision record at the sorting point. Identify the return source, bottle family and reason an item is accepted, quarantined or rejected. The record does not need to predict every problem; it should make unclear cases visible to the person responsible for the next decision.
Map the physical routes for each outcome. Returned containers, quarantine items and accepted washed bottles should be identifiable through the workflow. Include the handling of crates, loose closures and labels so the washer is specified around the real incoming stream rather than an idealised supply of empty bottles.
- Decision ownership
- State who may release a quarantined bottle family and what evidence that decision requires.
- Capacity record
- Track incoming quantity separately from the number accepted for washing and the number released afterwards.
Why record rejected bottles before the washing stage?
The record helps explain the difference between incoming volume and useful output and identifies return conditions the proposed process is not intended to handle.
