Whole bottles
Post-consumer bottles before shredding, with caps, labels, color and deformation still in the stream.
Buyer's Guide
Choose the right sorter for your material.
Don't start from a machine name. Start from what you're sorting and the result you need — then match it to the MAS platform that fits, and prove it on your own material.
01
Start from your material form
How the material arrives at the sorter decides the platform before anything else.
Prepared flakes & rigid fragments
Washed or unwashed plastic flakes and rigid pieces that have already been size-reduced.
Crushed glass cullet
Recycled glass cullet that needs color recovery and removal of ceramics, stone, porcelain and metal.
Grains, seeds & nuts
Rice, beans, seeds and nuts sorted by visible color, shape, size and foreign material.
02
Define the sorting boundary
What separates an accepted piece from a rejected one — color, material, or shape and foreign material?
Color & appearance
Separate by visible color, transparency, surface staining or discoloration — keep the clean fraction, reject off-color or off-class pieces.
Material type
A color-correct piece can still be the wrong material — PVC hiding in clear PET, or ceramic in glass. You need to remove non-target material a visible check cannot catch.
Shape, size & foreign material
Broken, deformed or undersized pieces plus stones, husk, shell, metal and other non-target objects that have to leave the stream.
03
Match it to a MAS platform
Mayson platforms cover plastic, glass and food & grain streams. Find the row that matches your input and boundary.

04
Validate with a material test
Before you commit, confirm the result on your own samples — accepted, rejected and borderline pieces.
A representative test turns a shortlist into a verified configuration. Send accepted classes, the rejects you need removed, and any borderline or contaminated examples from your line.
FAQ
Quick answers before you choose
Whole bottles or flakes?
Decide before you size-reduce. If you still have whole bottles, MAS-B classifies them before shredding so contamination never enters the flake stream. If the material is already flaked, look at MAS-C, MAS-P or MAS 3D.
Color sorting or material sorting?
If a visible color check defines your quality, MAS-C is enough. If color-correct pieces can still be the wrong polymer — for example PVC hiding in clear PET — you need material sorting with MAS-P, or MAS 3D when both matter.
What about grains, seeds, nuts or glass?
The same logic applies beyond plastics. Rice, beans, seeds and nuts sort on color, shape and foreign material with the MAS RG, MAS AS and MAS N platforms; recycled glass cullet sorts on color and contaminants with the Glass Recycling Sorter.
Do I still need a material test?
Yes. Final capability depends on your material, color overlap, additives, contamination, and the selected configuration. A representative sample test finalizes the sorting route and machine setup.
