Systém pro recyklaci lahví z PET určených pro potravinářství | Drcení a mytí

As global sustainability initiatives gain momentum, food-grade PET bottle-to-bottle recycling has emerged as a critical process for beverage and packaging manufacturers. This advanced closed-loop system ensures that post-consumer PET bottles are efficiently converted into high-quality, food-grade recycled PET (rPET) suitable for new beverage and food packaging. Central to this operation are industrial shredding, crushing, and washing solutions—technologies that guarantee material purity, operational efficiency, and compliance with international safety standards.

Food-grade PET recycling supports a circular economy by significantly reducing plastic waste, conserving resources, and lowering production costs. With regulations tightening on single-use plastics and consumer demand shifting toward eco-friendly packaging, investing in a reliable recycling system is no longer optional—it’s a strategic business decision.

Understanding the PET Bottle-to-Bottle Recycling Process

The transformation of used PET bottles into food-grade rPET involves multiple stages, each designed to remove contaminants and ensure the material meets stringent safety requirements.

Shredding & Crushing

The process begins with shredding and crushing, where post-consumer PET bottles are reduced into uniform flakes. This step increases surface area, improving the efficiency of subsequent washing and cleaning stages. Industrial shredders, like those from Rumtoo Machine, are engineered for high throughput, low energy consumption, and minimal maintenance.

Pre-Washing & Sorting

After shredding, flakes undergo pre-washing to remove labels, adhesives, caps, and other non-PET materials. Advanced sorting mechanisms, including air classifiers and sink-float tanks, separate PET from PVC, PP, or PE contaminants.

Hot Washing & Chemical Treatment

Flakes are subjected to hot caustic washing, which effectively eliminates oils, glue residues, and organic matter. This stage is critical for achieving the purity levels required for food-contact applications.

Rinsing & Drying

Thorough rinsing removes any remaining cleaning agents, followed by centrifugal drying and hot air treatment to reduce moisture content. Proper drying prevents microbial growth and ensures product integrity.

Decontamination & Pelletizing

The clean PET flakes are extruded, decontaminated under high temperature and vacuum, and pelletized into uniform rPET resin. This material is tested to meet FDA, EFSA, and other global food safety standards before being approved for reuse.

Applications of Recycled Food-Grade PET

Recycled PET is versatile and meets rigorous safety and performance standards across industries:

• Beverage Bottles: rPET is widely used in producing new water, juice, and soda bottles.
• Food Packaging: Ideal for clamshells, trays, and containers due to its clarity and durability.
• Pharmaceutical Containers: Complies with strict hygiene and material purity regulations.
• Textile Manufacturing: Converted into polyester fibers for sustainable apparel and home textiles.
