Collection and Segregation Technology
- Technology Used: Smart Waste Management Systems
We use automated collection systems and smart sensors that help in the efficient collection of plastic waste from various sources. These systems ensure that the waste is segregated at the point of collection, improving the quality of recyclables from the start.
Specialty: The technology reduces contamination in plastic waste, leading to higher efficiency during the recycling process.
Machinery: Conveyor Belt Sorting Systems
- Role: Conveyor belt systems are used for the initial sorting of plastic waste into different types based on resin codes, color, and contamination level.
- Specialty: The conveyor systems come equipped with optical scanners that can quickly identify and sort different plastic materials.
Cleaning and Washing Technology
- Technology Used: Hot Wash Technology
The hot wash technology uses high-temperature water and detergents to remove contaminants like oils, adhesives, labels, and other impurities from plastic waste.
Specialty: This process is essential for producing clean plastic flakes that are suitable for high-quality resin production. It significantly improves the purity of recycled materials.
Machinery: Friction Washers and Float-Sink Tanks
- Role: Friction washers are used to scrub the plastic flakes, ensuring that they are free from dirt and residues. Float-sink tanks help separate plastics based on density, allowing for the removal of heavier contaminants.
- Specialty: These machines enhance the quality of the recycled plastic by ensuring that only clean and separated materials move to the next stage of recycling.

Shredding and Size Reduction Technology
- Technology Used: Granulators and Shredders
Plastic waste is passed through granulators and shredders that reduce its size into small flakes or granules. This step is crucial for handling large volumes of plastic and preparing them for melting.
Specialty: The granulators are designed to handle a variety of plastic types, including Polyethylene (PE) and Polypropylene (PP), converting them into uniform-sized flakes.
Machinery: High-Speed Granulators
- Role: These machines break down large pieces of plastic into smaller, manageable flakes or granules that are easy to process in the extrusion phase.
- Specialty: The high-speed operation of these granulators ensures efficient processing, reducing energy consumption and increasing throughput.
Extrusion and Pelletizing Technology
- Technology Used: Twin-Screw Extruders
The extruders melt the cleaned plastic flakes, converting them into a uniform resin that can be shaped into pellets. This phase also includes the addition of stabilizers and additives to enhance the resin’s properties.
Specialty: Twin-screw extruders are ideal for producing high-quality recycled resin with consistent properties and color stability.
Machinery: Pelletizing Systems
- Role: Once the melted plastic is processed through the extruder, it is cooled and cut into uniform pellets using pelletizing systems.
- Specialty: The pelletizing system ensures that the recycled plastic resin meets the required standards for reuse in manufacturing new products.
Deodorization and Quality Enhancement Technology
- Technology Used: USFDA Approved Deodorization Units
Our deodorization technology eliminates any volatile organic compounds (VOCs) and residual odors from the recycled resins, making them suitable for food-contact applications.
Specialty: This step ensures that the recycled resins are free from odors, enhancing their usability in sensitive applications like food packaging.
Machinery: Vacuum Deodorization Chambers
- Role: These chambers work under vacuum conditions to extract unwanted gases and odors from the plastic resin, improving its quality.
- Specialty: The vacuum process is highly effective in producing odor-free recycled resin suitable for high-standard applications.
Advanced Filtration Systems
- Technology Used: Fine Filtration and Contaminant Removal
Our fine filtration technology ensures that even the smallest contaminants are removed from the recycled plastic during the melting process, maintaining the highest purity levels.
Specialty: The filtration system guarantees that the recycled plastic resin is free of impurities, enhancing its performance in various industrial applications.
Machinery: Fine Mesh Filters and Continuous Screen Changers
- Role: These systems continuously filter out impurities during the extrusion process, ensuring consistent resin quality.
- Specialty: They enable smooth operation with minimal downtime, making the recycling process more efficient and reliable.
