ブログ について JFE Plast Advances Sustainable Plastic Recycling with New Pellet Tech

Discarded plastic bottles and packaging materials are undergoing remarkable transformations through advanced recycling processes. What was once considered waste now serves as raw material for durable flower pots, heavy-duty logistics pallets, vehicle safety components, and even rainwater collection systems. This circular economy approach represents the cutting edge of sustainable manufacturing.

Recycled plastic pellets—uniform granules measuring 3-5 millimeters—are produced through a meticulous process involving collection, sorting, washing, melting, and extrusion. These pellets simplify plastic product manufacturing while giving discarded materials new purpose through resource recovery.

Leading manufacturers employ two sophisticated pelletization methods to meet diverse industrial requirements:

• Composition: Primarily polyolefin-based for versatile applications
• Melt Flow Rate: 3-4 g/10min (190°C, 2.16kg) for optimal processing
• Physical Properties: Cylindrical shape (3φ×3mm) with bulk density >0.5 g/cm³
• Quality Standards: Moisture content <0.5%, chlorine concentration <0.3%

• Enhanced Characteristics: Elliptical cylindrical form (3φ×3mm) with bulk density >0.55 g/cm³
• Superior Purity: Foreign matter content <0.2% for high-performance applications
• Processing Advantages: Consistent melt flow properties ideal for automated production

High-grade recycled pellets demonstrate exceptional performance across multiple sectors:

• Horticulture: Weather-resistant planters and propagation trays with extended service life
• Logistics: Structural components for material handling systems
• Automotive: Safety-critical interior components meeting rigorous standards
• Urban Infrastructure: Water management systems supporting sustainable cities

Modern recycling facilities combine substantial production capacity—reaching 4.8 metric tons per hour—with precision extrusion technology. Twin-screw (150φ) and single-screw (105φ) extruders enable efficient large-scale processing, while specialized strand-cut systems produce finer 60-mesh granules for demanding applications.

Through rigorous quality control and continuous process optimization, recycled plastic pellets now match virgin materials in performance for many industrial uses. This technological advancement represents a significant step toward circular material economies and sustainable manufacturing practices.
