The European Union's Single-Use Plastics Directive (SUPD)—Directive (EU) 2019/904—has transitioned from a future compliance obligation to an immediate operational reality. As of January 2025, every PET beverage bottle placed on the European Economic Area (EEA) market must contain a minimum of 25% post-consumer recycled plastic content, calculated as an average across all PET bottles placed on the market by each member state. The mandate escalates to 30% mandatory recycled content from January 2030.
For recycling plant operators, washing-line investors, and plastic converters worldwide, this regulatory architecture creates structural, non-discretionary demand for food-grade recycled PET (rPET) pellets—and by extension, for pelletizing equipment capable of producing food-contact-compliant output. Non-compliant EU member states face potential infringement proceedings, and brand owners whose supply chains fail to meet recycled-content thresholds risk market-access restrictions and reputational damage.
This article analyzes the compliance landscape, explains why CE-certified plastic pelletizing lines are essential for European market access, and demonstrates how Chenxing Machinery's PP/PE/PET dry-strips-cutting granulation system addresses the technical requirements of food-grade rPET production.
The SUP Directive represents a fundamental shift in regulatory philosophy. Prior to 2019/904, recycled-content targets were predominantly voluntary, industry-led initiatives with no enforcement mechanism. The SUPD transforms recycled-content procurement into a legal compliance obligation with direct financial consequences.
| Deadline | Requirement | Material Scope |
|---|
| January 2025 | 25% minimum recycled plastic content | PET beverage bottles (primary component) |
| January 2030 | 30% minimum recycled plastic content | PET beverage bottles (primary component) |
| Ongoing | Separate collection target: 77% of placed-on-market volume by 2025, 90% by 2029 | All single-use plastic beverage bottles ≤3 liters |
The directive's recycled-content calculation methodology—specified in Commission Implementing Decision (EU) 2021/1752—requires member states to compute the average recycled content as a proportion of all PET bottles placed on the national market. This averaging mechanism means that every bottle entering the EU supply chain contributes to the compliance denominator, creating demand that extends far beyond the premium-brand segment.
While the SUPD's recycled-content mandate currently applies explicitly to PET beverage bottles, several legislative developments signal imminent expansion:
The proposed EU Packaging and Packaging Waste Regulation (PPWR)—which has advanced through trilogue negotiations—introduces recycled-content targets for contact-sensitive packaging (including food-contact polyolefins) and all plastic packaging by 2030 and 2040, respectively.
The EU Ecodesign for Sustainable Products Regulation (ESPR) , which entered into force in July 2024, establishes a framework for mandatory recycled-content requirements across product categories including electronics, textiles, and construction materials.
National-level legislation in Spain, Italy, France, and the Netherlands is exceeding EU minimum thresholds, creating a patchwork of progressively stringent sub-national requirements.
These developments confirm that the SUPD represents the beginning—not the end—of a regulatory trajectory that will systematically expand recycled-content mandates across polymer types and application sectors. Recyclers who invest now in pelletizing lines capable of producing food-grade rPET and high-purity rPE are building capacity for demand that will intensify through 2035 and beyond.
Food-contact recycled plastics entering the EU market must be produced through recycling processes that have received a positive scientific opinion from the European Food Safety Authority (EFSA) . While EFSA evaluates the complete recycling process—including washing, decontamination, and extrusion—the pelletizing stage plays a critical role in maintaining the material purity achieved upstream.
Producing EFSA-compatible rPET pellets imposes specific technical demands on the pelletizing line:
Contamination prevention: The pelletizing system must prevent re-contamination of decontaminated material through contact with non-food-grade surfaces, lubricants, or environmental pollutants.
Temperature control: Precise melt-temperature management in the extruder module preserves intrinsic viscosity (IV)—a critical quality parameter for bottle-grade rPET. IV degradation during granulation directly affects downstream preform injection and stretch-blow molding performance.
Pellet uniformity: The 3 mm uniform pellet length produced by the rotating-blade cutter (Φ200 × 200 mm) and vibrating sieve screening unit ensures consistent melt behavior in downstream processing, reducing scrap rates for bottle manufacturers.
Residual moisture control: The integrated dryer/blower module must reduce surface moisture to levels compatible with food-contact processing, preventing hydrolytic degradation during subsequent SSP (Solid State Polycondensation) or extrusion steps.
According to Kitech Recycling's analysis of SSP-compatible rPET pelletizing systems, energy consumption for the pelletizing stage runs approximately 0.2–0.4 kWh/kg, with combined SSP and pelletizing line energy at 0.5–0.9 kWh/kg total. Uniform pellet IV—with a coefficient of variation (CV) below 0.04 dL/g—is significantly more valuable to downstream bottle manufacturers than higher average IV with wide variation, as it enables tighter process control and consistent bottle quality.
Machinery placed on the EEA market must bear CE marking, indicating conformity with applicable EU health, safety, and environmental protection requirements. For recycling and pelletizing equipment, relevant directives include the Machinery Directive (2006/42/EC) , the Low Voltage Directive (2014/35/EU) , and the Electromagnetic Compatibility Directive (2014/30/EU) .
Chenxing Machinery holds CE certification across its pelletizing and recycling equipment portfolio, alongside ISO 9001:2015 quality management system certification. This dual-certification framework provides European buyers with documented assurance of:
Machinery safety compliance under the Machinery Directive
Electrical safety conformity under the Low Voltage Directive
Quality management processes covering design, manufacturing, inspection, and after-sales service
For recyclers targeting the European market, purchasing CE-certified equipment eliminates the need for independent conformity assessment, accelerates installation and commissioning timelines, and reduces regulatory risk. Non-CE equipment may be denied entry at EU customs or require costly retroactive certification.
While rPET dominates the regulatory conversation, recycled polyethylene (rPE)—including rHDPE and rLDPE/LLDPE—represents a massive, growing market segment that operates under less stringent food-contact constraints. The washing and recycling production line combined with a multi-material pelletizing line enables recyclers to produce:
rHDPE pellets for pipe extrusion, blow-molded containers, and construction profiles
rLDPE/LLDPE pellets for film production, garbage bags, and construction sheeting
rPP pellets for automotive components, injection-molded consumer goods, and pallets
The Asia-Pacific region's dominance in recycled-resin production—accounting for over 56% of global capacity, with China producing approximately 34 million tons in 2025—positions regional recyclers to serve both domestic and export markets. Chenxing's manufacturing base in China provides proximity advantages for Asia-Pacific customers, while CE certification ensures European market access.
For recyclers who seek to integrate upstream material handling with downstream pelletizing, Chenxing's automatic compounding system and mixing units enable precise dosing, blending, and feeding of recycled flakes, regrind, and additives—reducing labor costs and improving batch-to-batch consistency.
The pelletizing technology landscape offers multiple architecture choices, and the selection decision carries significant implications for product quality, energy consumption, and operational complexity.
| Parameter | Dry-Strips-Cutting (Chenxing PP/PE/PET Line) | Water-Ring Pelletizing | Underwater Pelletizing |
|---|
| Cooling medium | Ambient air / cooling section | Water ring | Pressurized water |
| Residual moisture | Minimal (blower/dryer removes surface moisture) | Requires centrifugal drying | Requires intensive drying |
| Material compatibility | PVC, PE (all grades), PET, engineering plastics | Primarily polyolefins (PE, PP) | Broad compatibility |
| Energy consumption | 15–55 kW (modular) | Higher (pump + dryer energy) | Highest (pressurized water system) |
| Pellet shape | Cylindrical (cut from strand) | Spherical / lenticular | Spherical |
| Maintenance complexity | Low (modular, accessible) | Medium | High (die-face cutting) |
The dry-strips-cutting architecture offers distinct advantages for recyclers processing post-consumer waste streams with variable composition:
Feedstock flexibility: Unlike water-ring systems optimized for polyolefins, dry-strips-cutting accommodates PVC, PET, and engineering plastics without requiring extensive changeover procedures.
Lower energy intensity: At 15–55 kW across the 50–300 kg/h capacity range, the system's energy profile supports favorable unit economics, particularly in regions with elevated electricity costs.
Simplified maintenance: The modular, linearly arranged architecture—with extruder, cooling section, dryer, cutter, and sieve as physically distinct units—enables targeted maintenance without full line shutdown.
Reduced water consumption: By eliminating the water-ring process loop, the system avoids wastewater treatment costs and water-scarcity constraints applicable in many recycling-intensive regions.

The mandate applies to products placed on the EU market, regardless of manufacturing location. Non-EU recyclers exporting rPET pellets to European converters must ensure their material meets the recycled-content threshold and is produced via an EFSA-evaluated process. Chenxing's CE-certified pelletizing line provides a documented equipment foundation for this compliance pathway.
Food-grade rPET must meet EFSA decontamination standards ensuring that potential chemical migrants from post-consumer waste are below levels of toxicological concern. Fiber-grade rPET has less stringent purity requirements. The pelletizing stage must preserve the decontamination achieved in upstream washing and SSP processes.
