PET Bottle Recycling
Convert baled post-consumer PET bottles into washed flakes for bottle-to-bottle decontamination routes, APET sheet, strap, and fiber. Rumtoo configures de-baling, label removal, hot washing, sink-float separation, metal control, and drying around your bale profile, PVC risk, and final flake specification.

The line is built around contamination control, not just mechanical throughput.
Compressed bottle bales are opened into a stable flow. Pre-sorting removes metal, non-PET containers, and visible PVC or full-body sleeve risk before size reduction.
Bottles are wet-crushed into flake while water-assisted scrubbing starts to release paper, film labels, sugar residue, dirt, and fines before deep washing.
Hot washing dissolves glue, organics, oils, and difficult residues. Friction washers and rinse stages then strip loosened contamination from the flake surface.
Sink-float tanks remove PP/PE caps, rings, and light carryover. Metal detection, centrifugal drying, and thermal stages prepare PET flakes for stable storage, SSP feed, or extrusion.
PET projects fail on small amounts of wrong material. Sorting, label control, and sink-float separation reduce PVC and PP/PE carryover before flakes reach downstream melting.
Dry and wet label removal, hot wash, and repeated rinsing help reduce adhesive residue, sugar, dirt, and odor so the flake is easier to sell or process.
PET is moisture-sensitive. Matched drying and handling reduce hydrolysis risk before downstream decontamination, sheet extrusion, strapping, or fiber production.
PVC contamination, neck-label films, or full-body sleeves damage PET flake value and can ruin melt processing.
Front-end sorting, label removal strategy, and flake purification are built around the actual bottle mix instead of assuming every bale behaves the same.
Residual glue and sticky label debris keep showing up after washing.
Hot wash temperature, chemistry, residence time, and friction stages are tuned to dissolve and remove adhesive rather than simply move it downstream.
Municipal bale quality changes week to week, causing unstable flake purity and more stoppages.
Rumtoo sizes pre-wash, purge points, sorting intensity, and water handling around the contamination baseline instead of a nominal nameplate only.
Flakes leave the line too wet, too dusty, or too variable for the next stage.
Drying, fines management, and discharge handling are matched to the actual downstream route so the flake can move consistently into SSP, extrusion, or packing.
A quick visual check of incoming bottle condition and final flake quality for PET line evaluation.
Real PET bottle projects start with mixed post-consumer input carrying labels, caps, dirt, and moisture. Front-end sorting, debaling, and pre-wash stages have to stabilize this material before deep washing.
Final washed flake quality is judged by cleanliness, label carryover, moisture, and particle consistency. This is the material condition downstream buyers evaluate for sheet, fiber, or pellet routes.
A working view of PET bottle washing, friction cleaning, and line-side material handling.
Super-clean washed flakes prepared for SSP or approved decontamination processes used in bottle-grade recycling projects.
Flakes for sheet extrusion where color, glue residue, and moisture control directly affect clarity and downstream processing stability.
A common route for washed PET flakes when projects target stable feed preparation for spinning and fiber applications.
Washed flakes used in strapping projects that need cleaner feed and lower contamination carryover into extrusion.
High-purity washed flake sold as an intermediate feedstock when the project stops before pelletizing or bottle-grade decontamination.
Lines configured around bottle color mix, label burden, and bale source when output targets are fiber or industrial-grade instead of clear B2B.
| Line Family | Typical Throughput | Target Output Condition | Typical Process Route |
|---|---|---|---|
| PET Line 500-1000 | 500-1000 kg/h | Washed flake for fiber or sheet routes | Debaling + label removal + wet crush + hot wash + sink-float + drying |
| PET Line 1000-2000 | 1000-2000 kg/h | Higher-purity flake with tighter contamination control | Adds stronger sorting, rinsing, and drying control |
| Bottle-Grade Prep Route | 2000-5000 kg/h | Super-clean flakes prepared for SSP input | Requires tighter sorting, hot wash control, metal removal, and final QC |
| Final Moisture Window | Project target | Typically below 1% before storage or extrusion prep | Exact target depends on downstream route and handling method |
| Utilities | Project-specific | Water recirculation, heat, sludge, and QC planning | Sized by bale contamination, label load, and quality target |
Reference values depend on bale source, label mix, PVC risk, PO carryover, color split, downstream route, and the laboratory quality targets defined by the project.
These inputs matter more than a nominal kg/h figure when the project is judged on flake purity and downstream acceptance.
Specify whether the feed arrives baled or loose, then define clear, light blue, green, mixed color, or opaque bottle content, plus the share of water bottles, CSD bottles, oil bottles, trays, or non-bottle PET.
Describe PVC risk, aluminum closures, paper labels, shrink sleeves or full-body sleeves, label substrate density, wash-off or non-wash-off adhesive behavior, sugar residue, dirt, stones, metal, and polyolefin cap/ring load.
Clarify whether the flake goes to SSP, sheet, strap, fiber, or resale, and define moisture, PVC, PO, color, dust, and glue targets if you already test them.
Provide power, water, heating method, sludge and wastewater plan, floor space, and any FAT/SAT or sampling criteria you need for line acceptance.
| Decision Criteria | Basic PET Wash Line | Rumtoo PET Integrated System |
|---|---|---|
| Label and Glue Removal | Limited to a basic mechanical route | Dry/wet removal + hot wash + friction logic matched to bottle mix |
| Contamination Risk Control | Weak handling of PVC and PO carryover | Sorting, sink-float, and purge logic designed around purity targets |
| Moisture and Discharge Stability | Variable moisture and fines load | Drying and discharge matched to SSP, extrusion, or storage route |
| Adaptability to Bale Variation | Set up once and hope for consistency | Project design and operating windows account for changing municipal bale quality |
| Downstream Readiness | Generic washed flake output | Flake route aligned to bottle-grade, sheet, strap, or fiber objectives |
Not every PET project uses the same hot-wash intensity, but most post-consumer bottle lines need a hot wash stage to remove glue, organics, and difficult residue. The right setup depends on bale quality and downstream flake target.
No. Food-contact use depends on the full approved recycling route and regulatory assessment. The washing line is the critical super-cleaning front end, but bottle-to-bottle projects usually still rely on validated downstream decontamination such as SSP and customer-specific compliance review.
At minimum, buyers should define whether the feed is baled or loose, bottle color mix, label format, full-body sleeve burden, adhesive release behavior, PVC risk, PP/PE cap and ring load, dirt and organics, target moisture, and the downstream flake use. Those factors drive sorting, hot wash, sink-float, and drying scope.
Because they influence both sorting and washing performance. Full-body sleeves can hide bottle resin during optical sorting, while adhesive type and label substrate determine how much residue, discoloration risk, and floating contamination remain after grinding, hot wash, and sink-float separation.
PVC can degrade and discolor PET during melt processing, while PP/PE caps and rings reduce final resin consistency. PET lines are judged not just by throughput, but by how tightly they control these contaminants lot after lot.
