Development Scale of International Recycling Networks

According to data from the Global Polystyrene Sustainability Alliance, 72 countries participating in the United Nations plastic pollution treaty negotiations had established expanded polystyrene (EPS) recycling systems by 2023. Notably, over 30% of these countries achieved EPS recycling rates exceeding the critical 30% threshold, reflecting global recognition of the material’s recyclability. The United Nations Environment Programme has identified polystyrene as one of the six major plastic materials with large-scale recycling potential, underscoring its unique role in the circular economy.

Standardized Recycling Process Flow

The mainstream polystyrene recycling process follows a three-stage model of “crushing-compaction-pelletizing.” Professional recycling plants typically adopt a sequential procedure of crushing followed by compaction, ensuring thorough material processing. Against this backdrop, integrated EPS compactors that combine crushing and compaction functions have gained broad market acceptance. However, in practical applications, not all customers require compaction. For example, manufacturers producing cushioning packaging for express delivery using shredded polystyrene materials only need to process raw materials to the appropriate size. Additionally, some recycling users exclusively handle diverse non-metallic materials such as woven bags, plastic products, paper, wood, fiber, and rubber. In such cases, specialized crushing equipment offers better adaptability.

Equipment Applicability Analysis

Using food processing equipment as an analogy: a soybean milk machine may struggle to process sugarcane due to hardness beyond its tolerance—leading to blade jamming, juice extraction rates dropping to around 30%, or even equipment damage. Similarly, recycling equipment requires professional matching. While all-in-one EPS compactors offer simple operation and high efficiency, their crushing capacity may fall short for recycling enterprises with high processing demands or just need shredder. Such enterprises often opt for dedicated crushers, leveraging large-capacity crushing chambers and high-strength blade designs to achieve efficient preprocessing of diverse materials.

Equipment combination

For the recycling users who have subsequent requirements for compaction,these are then paired with hydraulic cold-compaction lines or hot-melt production systems for material compression. This specialized equipment configuration effectively avoids the efficiency bottlenecks that “all-in-one” machines may encounter when processing specialized materials.

Recommendations

We hereby recommend the Qinfeng CF Series Shredders:

The CF-SS Single-Shaft Shredder processes various materials including plastics, paper, wood, fiber, rubber, organic waste, and multiple non-metallic materials. Output can be used directly or fed into further size-reduction processes.

The CF-TS Dual-Shaft Film Shredder is tailored for medium-hardness and soft materials like films, woven bags, container bags, and paper. Its dual-shaft design operates at medium speed while offering low noise, high efficiency, and automatic feeding without push-feeding requirements.
