Whole-Bottle
Sorting Before
Shredding
The MAS-B Bottle Sorting Series classifies mixed post-consumer bottle streams by polymer, color and bottle class upstream of size reduction. Delivering purer fractions, higher flake quality and greater recycling efficiency.




Feed
Whole bottles conveyed in original form.
Inspect
Evaluate material, color and bottle class using advanced detection.
Classify / Eject
Accurately separate accepted fractions and reject streams before shredding.
Why MAS-B
Make bottle-level decisions while you still can.
MAS-B sorts whole bottles before shredding, when bottle color, material direction, label and shape are all still readable.
Sort whole bottles, before shredding
Make routing decisions while bottle-level information is still visible, not after everything becomes mixed flakes.
Cleaner downstream routing
Send target bottle classes to the right washing, grinding and flake-preparation path from the start.
Class by color, material & condition
Bottle color, material direction, label coverage and deformation are reviewed together against your classes.
Real-sample configuration
Built from your actual accepted and off-class bottles, including labeled, capped and crushed examples.
Earlier off-class removal
Pull non-target bottles out before they are shredded into a harder, lower-value flake mixture.
Existing-line friendly
Feed, spacing, reject outlets and downstream handoff are planned around your current line.
Main applications
Sort bottles before they become flakes.
MAS-B is positioned by the bottle decision you need to make early, while bottle-level information is still visible and useful.

Application 01
Pre-shredding bottle routing
Sort mixed bottle intake while it is still whole — route target bottles to the right downstream path before shredding turns everything into a harder flake mixture.

Application 02
PET vs non-PET bottle classes
Separate clear and mixed-color PET bottles from non-PET, or recover a selected PE bottle stream — all defined by your real bottle classes.
Whole-bottle stream
Bottle feed, accepted bottles and off-class rejects.
MAS-B decisions start before shredding. Bottle color, material direction, label condition and deformation should be represented in the sample set.

Visual examples are illustrative. Bottle sorting results depend on the material, presentation, selected configuration and operating conditions.
Raw materials
Bottle classes MAS-B is built to separate.
Switch between bottle families and click any class to see the feed, the accepted bottle stream and the off-class rejects.
Recovering a clean PET bottle stream from mixed intake.

Mixed feed
Incoming whole bottles — PET mixed with non-PET, labeled, capped and compressed examples.
Accepted and reject classes are always confirmed on your representative samples before a configuration is quoted.

The platform
A whole-bottle sorting platform that fits ahead of shredding.
Consistent bottle singulation, class-aware inspection and reliable diversion are tuned to the bottle classes you confirm in testing.
How it works
Bottle sorting needs spacing and line context.
The workflow should not be described as a generic flake sorter because bottle presentation drives the decision.
- 01Customer-prepared
Open & feed bottles
Baled or loose bottles are opened, metered and fed onto the line. Compression level and dirt set how well each bottle can present to the inspection zone.
- 02Singulation
Singulate & present
Bottles are spaced and oriented so each one is seen individually, with labels, caps and deformation in view rather than overlapping in a pile.
- 03Bottle inspection
Inspect the bottle class
Each bottle is read for color, material direction, label coverage and shape against the bottle classes you defined for the project.
- 04Accept / reject
Decide against your samples
Bottles are matched to the accepted and off-class examples from your real stream, including the difficult labeled, capped and crushed cases.
- 05Diversion
Divert & route
Off-class bottles are diverted to reject; accepted bottle classes continue toward shredding, washing and flake preparation on the right downstream path.

Buyer questions
What buyers ask before specifying a MAS-B.
Straight answers on sorting before shredding, bottle classes, labels and deformation, and what to send for a sample review.
Is MAS-B for flakes?
No. MAS-B is for whole-bottle sorting. Flakes should be reviewed under MAS-C, MAS-P or MAS 3D.
Can MAS-B handle labeled bottles?
Labeled bottle streams can be reviewed, but detectability depends on labels, presentation, target class and configuration.
Can MAS-B guarantee bottle purity?
No fixed purity should be promised without representative sample testing and line-context review.
Where does MAS-B fit in a recycling line?
It fits before size reduction when bottle-level sorting is useful before shredding or washing.
Real sample testing
Use your own bottle stream before finalizing the sorting direction.
A MAS-B project should start from real whole bottles, including target bottles, off-class bottles, labels, caps and deformation.
