Professional Production Line EPS Recycling Machine With 14.2kw Connected Load

Working Process

1. Feeding: Waste EPS is loaded into the machine, often via a hopper or conveyor belt.
2. Crushing: Large foam pieces are shredded into small flakes (≈1–5 cm), reducing volume by 50–70%.
3. Melting & Compression: The flakes are heated and pushed through an extruder, where they melt into a viscous liquid. The screw mechanism applies pressure to remove air and compact the material into a solid form (e.g., ingots or pellets).
4. Output: The final product (recycled polystyrene) is discharged, with a volume reduction of up to 90% compared to raw EPS waste.

Types of EPS Recycling Machines

1. By Processing Method

• Thermal Compression Machines
  • Use heat to melt EPS, suitable for clean, dry waste.
  • Example: Industrial-scale extruders used in waste management plants.
• Cold Compression Machines
  • Mechanical pressure (no heat) to compact EPS into blocks.
  • Ideal for on-site recycling in offices, supermarkets, or small factories.

By Capacity

• Small/Portable Machines
  • Processing capacity: 5–50 kg/h.
  • Used by small businesses or for mobile recycling units.
• Medium/Large-Scale Machines
  • Processing capacity: 100–500+ kg/h.
  • Deployed in recycling facilities or manufacturing plants.

Benefits

1. Environmental

• Reduces Landfill Waste: EPS takes hundreds of years to decompose; recycling diverts it from landfills.
• Low Carbon Footprint: Recycling EPS requires 75% less energy than producing virgin polystyrene.
• Plastic Circularity: Converts waste into raw materials for new products (e.g., picture frames, automotive parts, building insulation).

2. Economic

• Cost Savings: Reduces waste disposal fees (e.g., landfill taxes or hauling costs).
• Revenue Generation: Recycled polystyrene can be sold to manufacturers at ≈30–50% of the price of virgin material.
• Compliance with Regulations: Meets EU plastic recycling targets (e.g., 50% plastic packaging recycling by 2030) and corporate sustainability goals.

3. Operational

• Space Efficiency: Reduces EPS volume by 90%, lowering storage and transportation costs.
• User-Friendly: Automated machines require minimal labor and can operate 24/7 with basic maintenance.

Applications

• Waste Management Facilities: Process bulk EPS waste from commercial and residential sources.
• Manufacturing Industries: On-site recycling for EPS used in product packaging (e.g., electronics, furniture, appliances).
• Food & Beverage Sector: Recycle EPS cups, coolers, and packaging from restaurants and supermarkets.
• Construction & Insulation: Reclaim EPS from demolition waste for reuse in insulation boards.

Technical Considerations

1. Material Purity

• Contaminants (e.g., paper, glue, moisture) can degrade output quality. Pre-sorting and drying are often required.
• Solution: Install pre-treatment lines (e.g., sieves, dryers) for contaminated waste.

2. Energy Consumption

• Thermal machines require significant electricity for heating (≈50–200 kW/h, depending on capacity).
• Energy Efficiency Measures:
  • Use waste heat recovery systems.
  • Opt for cold compression machines for low-energy applications.

3. Output Specifications

• Recycled pellets typically have a density of 1.05–1.1 g/cm³ and a melt flow index (MFI) of 5–15 g/10 min (similar to virgin polystyrene).
• Customizable outputs: Pellet size, color, and additive blending (e.g., flame retardants for industrial use).

Market Trends

• Growing Demand: Driven by global plastic recycling policies (e.g., China’s "No Waste City" initiative, U.S. EPA’s Sustainable Materials Management program).
• Technological Innovation:
  • Development of hybrid machines (combining thermal and cold compression).
  • Integration with AI for real-time quality control (e.g., sensors to detect contaminants).
• Key Players: Companies like INTCO Recycling (U.S.), UNTHA (Austria), and TOMRA (Norway) lead the market in EPS recycling solutions.
