A PET recycling machine processes used polyethylene terephthalate bottles into reusable flakes or rPET pellets through baling, label removal, crushing, washing, drying, and pelletizing. Choosing the right PET recycling machine means matching three variables to your project: throughput capacity (200\u20132,000 kg\/h), feedstock condition (clean baled bottles vs heavily contaminated post-consumer waste), and output target (clean flake for fiber spinning vs food-grade rPET pellet for bottle-to-bottle).<\/p>\n

This buyer’s guide gives plant managers and procurement engineers a side-by-side decision matrix, three-year total cost of ownership data, capacity-specific configurations, and the eight pitfalls that derail PET line investments in emerging markets. Every section answers a real question we get from clients across Southeast Asia, MENA, Africa, and Latin America \u2014 the regions where most new PET recycling capacity comes online in 2026.<\/p>\n

What Is a PET Recycling Machine?<\/h2>\n

A PET recycling machine is a chain of unit operations \u2014 not a single device \u2014 that converts post-consumer or post-industrial polyethylene terephthalate waste into clean flakes or rPET pellets ready for re-extrusion into fiber, sheet, strapping, or new bottles. A complete line bundles 6 to 9 mechanical stages depending on the output grade required.<\/p>\n

Feedstock comes in three forms. Loose bottles<\/strong> arrive direct from collection or municipal MRFs and need a debaler-equivalent feed system. Baled bottles<\/strong> are compressed cubes of 200\u2013500 kg, which a debaler shreds open before processing. Pre-shredded flake<\/strong> bypasses the front end and enters the wash circuit directly \u2014 common when an upstream sorter ships flake-format material to a recycler.<\/p>\n

Output target dictates the line’s complexity. Cold-wash flake<\/strong> ends with sink-float separation and centrifugal dewatering, suitable for low-spec fiber and strapping. Hot-wash flake<\/strong> adds a caustic bath at 80\u201390 \u00b0C plus a friction washer, removing glue and surface contamination \u2014 suitable for sheet, fiber, and lower-grade bottle. Food-grade rPET pellet<\/strong> requires hot wash plus pelletizing with melt filtration and solid-state polycondensation (SSP), and demands FDA or EFSA letter-of-no-objection approval before contact-sensitive end use.<\/p>\n

The 7 Stages of a Complete PET Recycling Line<\/h2>\n

A PET recycling line breaks down into seven sequential stages. Each stage targets a specific contaminant or material transformation. Skipping or undersizing one stage shows up as a defect at the output: caps in flake, label residue in pellet, IV drop, or yellowing.<\/p>\n

Stage 1: Bale Breaking<\/h3>\n

A debaler tears open compressed bottle bales and feeds loose bottles onto the conveyor at a controlled rate. Without a debaler, operators must hand-cut wires and tip bales \u2014 a labor cost of 2\u20133 staff per shift that disappears at lines above 500 kg\/h. See the debaler machine for plastic recycling<\/a> page for capacity specs.<\/p>\n

Stage 2: Pre-Wash and Label Removal<\/h3>\n

A trommel screen removes loose stones, sand, and small debris before crushing. A dry-label remover then strips PVC sleeve labels mechanically, before they smear during wet processing. Hot-melt glue labels survive this stage and remove only after the hot wash.<\/p>\n

Stage 3: Crushing<\/h3>\n

A wet plastic granulator with a 12\u201314 mm screen reduces whole bottles to flake. Wet crushing \u2014 water sprayed into the cutting chamber \u2014 controls dust, cools blades, and starts dissolving water-soluble glue. The wet PET granulator<\/a> is the workhorse here; dry granulators are reserved for clean post-industrial scrap.<\/p>\n

Stage 4: Sink-Float Separation<\/h3>\n

A sink-float tank exploits density difference. PET (1.38\u20131.40 g\/cm\u00b3) sinks; HDPE caps and PP labels (0.91\u20130.95 g\/cm\u00b3) float and skim off. A well-designed tank with overflow weir and bottom auger achieves 99.5 % separation purity at 1,000 kg\/h throughput.<\/p>\n

Stage 5: Hot Wash (Optional but Critical for Bottle-Grade Output)<\/h3>\n

A caustic bath at 80\u201390 \u00b0C with 1\u20133 % NaOH plus a friction washer removes hot-melt glue, oils, and surface contamination. Hot wash is the gating step for food-grade output. Without it, IV value drops below 0.72 dL\/g and the pellet fails bottle-grade specifications. Power and water consumption roughly double when hot wash is added \u2014 plan for it at the start, not as a retrofit.<\/p>\n

Stage 6: Dewatering and Drying<\/h3>\n

A centrifugal dewatering machine<\/a> spins surface water off flake to 1\u20133 % moisture. A thermal dryer<\/a> then drops moisture to under 0.5 % \u2014 required before pelletizing or hot-loading into a silo. Skipping the thermal dryer causes melt-flow inconsistency and surface haze in the pellet.<\/p>\n

Stage 7: Pelletizing (rPET Output Only)<\/h3>\n

A PET flake single-screw pelletizer<\/a> melts dried flake at 270\u2013290 \u00b0C, filters through a 30\u201350 \u00b5m screen changer, and cuts into pellets. For food-contact applications, a downstream SSP reactor raises IV from 0.72 to 0.80+ dL\/g and removes residual VOCs.<\/p>\n

Decision Framework: How to Choose a PET Recycling Machine<\/h2>\n

Choosing a PET recycling machine is a three-axis decision: capacity \u00d7 feedstock condition \u00d7 output target<\/strong>. Get any one wrong and the line either runs starved (wasted CapEx) or overloaded (quality drop and downtime). Work through the three steps below in order \u2014 capacity first, because it locks the equipment class.<\/p>\n

Step 1: Match Capacity to Daily Throughput<\/h3>\n

Capacity is rated in kg\/h. To convert plant volume to a capacity tier, divide annual feedstock tonnage by 250 working days \u00d7 16 production hours (two-shift operation), then add 20 % headroom for downtime and feedstock surge. A plant processing 4,000 t\/year of bottles needs 4,000,000 \u00f7 (250 \u00d7 16) \u00d7 1.2 \u2248 1,200 kg\/h \u2014 round up to a 1,500 kg\/h tier.<\/p>\n

Step 2: Match Configuration to Feedstock Condition<\/h3>\n

Feedstock comes in three contamination grades. Clean post-industrial<\/strong> (factory off-cuts, color-sorted) needs only a basic cold-wash module. Mixed post-consumer<\/strong> (curbside collection, MRF output) needs full sink-float plus hot wash. Heavily contaminated<\/strong> (open dumpsite reclamation, agricultural film mixed with PET) needs an additional pre-sorting line and a double-pass friction washer \u2014 and some plants reject this grade entirely as not commercially viable.<\/p>\n

Step 3: Match Output to End-Market<\/h3>\n

The end-buyer specification determines whether you stop at flake or continue to pellet. Fiber spinners<\/strong> typically buy hot-wash flake at 6,000\u20138,000 yuan\/t. Sheet extruders<\/strong> can use cold-wash flake at 4,800\u20136,500 yuan\/t but accept lower purity. Bottle-to-bottle converters<\/strong> require food-grade rPET pellet at 9,500\u201312,000 yuan\/t \u2014 and only buy from suppliers with FDA or EFSA letters of no objection. Check the buyer specification in writing before sizing the line.<\/p>\n

PET Recycling Machine Types and Energycle Product Lines<\/h2>\n

A PET recycling line draws from seven equipment categories. Each equipment class has a single dominant function, and Energycle manufactures a flagship product in each. The pages linked below cover model variants, capacity ranges, and technical drawings for each category.<\/p>\n

PET Bottle Washing Line (Integrated System)<\/h3>\n

An integrated PET bottle washing line<\/a> bundles stages 1 through 6 into a single coordinated system, with shared PLC control and matched throughputs. Buying integrated rather than mixing components from multiple suppliers eliminates the throughput-mismatch failures that surface months into operation. Energycle ships integrated lines from 500 to 6,000 kg\/h.<\/p>\n

Single-Shaft Shredder for PET Bales<\/h3>\n

A single-shaft shredder<\/a> handles baled feedstock that needs primary size reduction before granulation. For PET-only operations the shredder often gets skipped \u2014 granulators handle whole bottles directly. Plants processing mixed plastic bales benefit from a shredder front end, which reduces granulator wear.<\/p>\n

Wet PET Granulator<\/h3>\n

The wet PET granulator<\/a> is the central machine of the entire line. Water injection during cutting controls dust, cools blades, dissolves water-soluble glue, and pre-rinses fines. A 200 kW model handles 1,000\u20131,500 kg\/h with rotary V-knife geometry. Blade material \u2014 D2 tool steel vs SKD11 \u2014 determines maintenance interval, with SKD11 lasting considerably longer at a higher price.<\/p>\n

Centrifugal Dewatering Machine<\/h3>\n

A centrifugal dewatering machine<\/a> spins surface water off washed flake to 1\u20133 % moisture using a vertical perforated drum at 1,000\u20131,400 rpm. This machine sits between the wash circuit and the thermal dryer; sizing it 20 % above wash-circuit throughput prevents back-pressure that floods the upstream tank.<\/p>\n

Thermal Dryer for Final Moisture Control<\/h3>\n

A thermal dryer<\/a> moves flake through a heated cyclone-and-pipe network to drop moisture from 1\u20133 % down to under 0.5 %. The dryer’s heat source \u2014 diesel burner, natural gas, or electric resistance \u2014 is the largest decision affecting operating cost. In regions with cheap natural gas (Iran, Saudi Arabia, Indonesia) gas is the lowest-cost option; in regions with cheap grid power (China, Vietnam) electric is competitive.<\/p>\n

PET Flake Pelletizer<\/h3>\n

The PET flake single-screw pelletizer<\/a> melts and re-forms dried flake into uniform pellets, with melt filtration removing residual contaminants. Ring-shaped die plates produce 3\u20134 mm pellets at 500\u20132,000 kg\/h. Twin-screw geometries are reserved for engineering plastics \u2014 single-screw is the correct choice for PET regrind.<\/p>\n

PET Bottle Baler (Upstream)<\/h3>\n

A PET bottle baler<\/a> compresses loose collected bottles into 200\u2013500 kg bales for transport between collection points and the recycling plant. While not part of the recycling line proper, the baler determines transport economics \u2014 a truck moving baled bottles carries several times the payload of one moving loose bottles.<\/p>\n

Capacity-Specific Configurations: 200, 500, 1,000, and 2,000 kg\/h<\/h2>\n

Capacity is the single decision that locks the rest of the equipment specification. Power draw, footprint, water consumption, and operator headcount all scale with throughput \u2014 but not linearly. Larger lines deliver lower per-kg processing cost, which is why operators consolidate into 1,000+ kg\/h tiers wherever feedstock volume justifies it.<\/p>\n

200 kg\/h: Pilot or Test Line<\/h3>\n

The 200 kg\/h tier exists for two scenarios: pilot-scale validation before scaling up, and small-batch processing of clean post-industrial scrap. Per-kg processing cost is much higher than at larger tiers, so this line rarely makes economic sense on full post-consumer feedstock. Operators using 200 kg\/h commercially typically supply a single fiber spinner with color-segregated flake at premium pricing.<\/p>\n

500 kg\/h: Entry-Level Commercial<\/h3>\n

The 500 kg\/h tier is the smallest commercially efficient post-consumer recycler. Hot wash becomes standard and staffing settles at around three operators per shift. Plants at this tier serve regional markets \u2014 a single state, province, or city’s collection volume \u2014 and rarely export.<\/p>\n

1,000 kg\/h: Mid-Volume Workhorse<\/h3>\n

The 1,000 kg\/h tier is the most common configuration sold globally. Per-kg processing cost approaches its practical minimum and the line fits a standard hall. This tier is the recommended starting point for any new recycler with confirmed, steady feedstock supply.<\/p>\n

2,000 kg\/h: Industrial Scale<\/h3>\n

The 2,000 kg\/h tier serves large MRF operators and bottle-to-bottle pellet producers. Two-shift operation processes around 8,000 t\/year, enough to supply a regional bottling plant. Plan for significant civil works (pit-mounted shredder, mezzanine, water treatment) on top of the headline equipment cost.<\/p>\n

Total Cost of Ownership: 3-Year Breakdown<\/h2>\n

Purchase price is only part of three-year ownership cost. Power, water, labor, maintenance, and spare parts together typically exceed the initial equipment cost by year three, so two quotes that look close on price can diverge once consumables and downtime are included.<\/p>\n

Per-kg processing cost typically falls as capacity rises, because labor and overhead are spread across more output. This is why operators with confirmed, steady feedstock usually favor larger lines despite the higher purchase price.<\/p>\n
