In a world overwhelmed by plastic waste, this new 200,000 tons/year mixed waste plastics recycling project marks a bold pivot. It doesn’t just reduce landfill use — it converts contaminated, hard-to-reuse plastics into high-value chemicals. The breakthrough hints that our circular economy ambitions may finally have scalable, industrial muscle behind them.

Project Overview: Turning Trash Into Treasure

This facility is engineered to accept varied streams of waste — from municipal mixed plastics to agricultural film, paper mill rejects, and other low-value plastic blends. Its core mission: reclaim value from what was once considered irredeemable.

With an input size typically between 100 mm and 400 mm, it shreds material to ≤ 30 mm, producing a consistent feedstock for downstream chemical recycling. The goal? To feed the chemical sector with propylene, ethylene, and other valuable monomers.

Key Technology: Harden SG2200RP Single-Shaft Shredders

At the heart of the plant are six Harden SG2200RP single-shaft shredders. Each unit is engineered for stability, durability, and versatility.

• Integrated screening system capable of refining output to 20 mm when required
• Four-edge rotatable blades to reduce wear costs and extend blade life
• Variable torque drive adapts to feedstock diversity
• Quick-adjustable cutting gap supports throughput up to 15 t/h (depending on input and material)

Why These Features Matter

Mixed waste plastics often vary in composition, contamination, and geometry. The adaptability built into the Harden SG2200RP ensures stable throughput, manageable energy consumption, and minimal downtime — essential in a large scale 200,000 ton/year operation.

Environmental & Economic Impacts

This project is far more than a shredder farm. It integrates chemical recycling downstream, enabling output of high-purity monomers ready for re-entry into manufacturing. Its impacts include:

• Reduced landfill and incineration: diverting plastics that otherwise escape reuse or recycling
• Lower greenhouse gas emissions: reclaiming value rather than burning or burying waste
• Water & energy savings: chemical recycling avoids resource-intensive purification of virgin feedstocks
• Creation of circular supply chains: enabling manufacturers to use recycled propylene and ethylene instead of fossil feedstocks

“By recycling instead of discarding, this plant unlocks plastics once thought unrecoverable — delivering both environmental and economic value.”

How It Handles Complexity in Mixed Waste Plastics

“Mixed waste plastics” is a notoriously messy category: multi-polymer blends, contamination, timing differences, and variable consistency. This project’s design mitigates those challenges:

• Pre-sorting and input grading to reduce oversized inert materials
• Adaptive torque control in shredders to avoid jamming
• On-line screening and recirculation to achieve uniform particle size
• Close integration between shredding and chemical recycling to buffer feedstock variation

Conclusion: A Leap Toward a Circular Plastic Economy

This 200,000-ton/year mixed waste plastics recycling project is more than an engineering feat. It’s evidence that with the right technology, we can reclaim value from the most challenging plastic waste streams. By merging adaptive shredding (via Harden SG2200RP) with chemical recycling, it reduces environmental burden and delivers usable, high-purity feedstock back to industry.
