Clean, Consistent Regrinds

We turn light PIR/PCR plastics into clean, dense flakes for smooth processing.

Clean, consistent regrinds

We use a cutter-compactor to convert light plastic waste (PIR/PCR) into clean, dense flakes. The machine heats the material by friction and cuts it into small, uniform pieces. After screening and metal removal, each batch is checked to maintain size (8–12 mm) and low moisture.

The process controls temperature to prevent degradation while improving bulk density. This makes the material easy to handle and process. The final flakes have stable melt flow and good consistency, making them suitable for compounding, extrusion, and injection at lower cost.


Traceable Feedstock Collection.

We source clean PIR/PCR scrap, sort it carefully, and prepare for safe regrinding.

Feedstock collection

We collect clean plastic scrap from trusted partners. Each batch is weighed, checked for polymer type, color, and contamination, then sorted and packed in jumbo bags for safe handling. This ensures traceability, steady supply, and consistent quality.

We record supplier details and accept only single-grade, non-mixed scrap to reduce processing risk and ensure good performance. The material is stored in a controlled environment to prevent moisture and contamination.

This strong quality control helps us deliver stable, reliable recycled materials suitable for compounding, film, and injection applications.


Reliable Logistics and Material Handling.

We transport materials safely and efficiently through well-managed logistics.

Feedstock collection

We use well-managed trucks to move materials safely and efficiently. Each shipment is handled with care to avoid damage, mixing, or contamination during transport.

Our team plans routes and timing carefully to ensure on-time delivery. This reliable logistics system helps us maintain a steady supply and consistent quality for our customers.


Reliable Regrinding and Material Preparation

Clean plastic scrap is carefully selected and processed into consistent flakes, making it suitable applications.

Feedstock collection

We use modern shredding machines to process plastic waste into clean, uniform flakes. The system runs smoothly, ensuring stable size and high efficiency during operation.

The processed material is easy to handle and suitable for compounding, extrusion, and injection. This helps us deliver consistent performance and reliable quality in every batch.
