Hammer Mills for Recycling Carpet

Why Carpet Recycling Is Gaining Momentum

Over the past several years, multiple U.S. states have introduced or expanded regulations aimed at reducing carpet waste and increasing recycled content in new carpet manufacturing. These initiatives are part of a broader push toward extended producer responsibility (EPR), shifting more end-of-life accountability to manufacturers and suppliers.

Key regulatory trends include:

• Minimum post-consumer recycled (PCR) content requirements in new carpet products
• Restrictions on certain backing materials and additives
• Increased diversion targets to reduce landfill disposal

While requirements vary by state, the direction is clear: carpet must be recyclable at scale. This shift is accelerating investment in processing technologies capable of handling post-consumer carpet efficiently and economically.

The Role of Size Reduction in Carpet Recycling

Size reduction is the foundational step in carpet recycling. By breaking down bulky rolls, tiles, and slabs into smaller, manageable particles, size reduction enables:

• Liberation of fibers from mineral-filled backing systems
• Reduction of material volume for efficient handling and transport
• Preparation of material for downstream separation technologies

Without proper size reduction, carpet materials remain too entangled and inconsistent for effective recovery.

Removing Calcium Carbonate Backing for Material Recovery

Many carpet backing systems contain high levels of calcium carbonate filler. While essential for carpet performance, this mineral content complicates recycling by contaminating fiber streams.

Schutte Hammermill size reduction systems are engineered to:

• Break down backing systems effectively
• Release calcium carbonate from polymer fibers
• Produce material suitable for air classification and separation

This process allows recyclers to recover cleaner polymer fractions while isolating mineral-heavy fines into separate output streams.

15 Series “Liberator” Hammer Mill

Designed for aggressive primary size reduction, การ 15 Series Liberator excels at processing tough, composite materials such as post-consumer carpet.

Key advantages:

• Effective liberation of backing systems and fibers
• Fixed rotor design for consistent, high-impact processing
• Capable of handling rolled, folded, or slab carpet

WA Series Hammer Mills

The modified WA series is ideal for secondary size reduction or refinement following primary processing.

Key advantages:

• Controlled particle sizing
• Consistent output for downstream separation
• Adaptable configurations based on material and throughput goals
