| Material | Recycling Rate | Energy Saved Through Recycling |
| Plastic | 9% | Significant energy savings compared to virgin plastic production |
| Paper | Higher than plastic | Energy savings vary by type of paper product |
| Metal | Higher than plastic | Substantial energy savings, especially for aluminum |
Plastic pollution harms our environment and food chain. It also hurts industries like fishing and tourism, costing $2.5 trillion a year. Knowing the plastic problem is key to solving it.
Understanding Different Types of Plastic
It’s important to know the different plastics for recycling. Each type has its own uses and recyclability.
Plastics are sorted into seven classes by resin codes. These codes help identify plastics and their recyclability. The seven types are:
- PETE (or PET) – used in food containers and bottles;
- HDPE – in sturdier items;
- PVC – versatile but rarely recycled;
- LDPE – very resilient;
- PP – in injection molding;
- PS – rarely recycled; and Other, including bioplastics.
PET (Code 1) and HDPE (Code 2) are most recycled. They have established recycling processes. At IPG, our equipment can handle many plastics, but some need special care.
What is the Process of Recycling Plastic: Step-by-Step
Recycling plastic involves many steps. It’s a complex process that needs precision and special equipment. We turn old plastic into valuable resources.
Collection and Sorting: The recycling journey starts with picking up plastics from recycling bins. They then go to recycling centers. There, plastics are sorted by type, color, thickness, and use. This step is key for correct and efficient processing.
| Sorting Criteria | Description | Method |
| Type | Plastics are categorized based on their resin type. | Manual or Automated Sorting |
| Color | Plastics are sorted by color to ensure uniformity. | Visual Inspection |
| Thickness | Plastics are sorted based on their thickness for processing. | Mechanical Sorting |
Cleaning and Shredding: After sorting, plastics get cleaned to remove dirt and residue. Then, they are shredded into smaller pieces. This makes the next steps more efficient.
Identification and Separation: Next, technologies help sort the shredded plastics further. Density tests and air classification are used. This ensures plastics are correctly separated.
Melting and Pelletizing: The final steps melt the plastics into a liquid state. This liquid is then shaped into new forms. The molten plastic is turned into pellets, ready for making new products. At IPG, we focus on making high-quality pellets.
Every step in recycling is vital for quality materials. Understanding these steps shows the importance of recycling plastics.
The Critical Role of Plastic Pelletizers
Plastic recycling pelletizings are key in recycling, and IPG specializes in them. Our pelletizers turn processed plastic into uniform pellets. These pellets are raw materials for new products.
Plastic pelletizers convert plastic waste into pellets. These pellets are used to make new plastic products, reducing virgin plastic use. At IPG, our equipment optimizes recycling, ensuring quality pellets.
The pelletizing process has several steps. First, molten plastic is extruded and cut into uniform pieces. Our pelletizers use advanced systems to purify the plastic. This transforms plastic flakes into standard pellets for manufacturing.
| Pelletizer Type | Material Processed | Output Quality |
| Single Screw Pelletizer | Polyethylene, Polypropylene | High-quality pellets with consistent size and shape |
| Twin Screw Pelletizer | Complex plastic mixes, including additives | Pellets with precise composition and minimal contaminants |
| Underwater Pelletizer | Various plastic types, including fragile materials | Pellets with smooth surface finish and uniform size |
Our pelletizers turn recycled plastic into high-quality pellets. This adds value to recycling, helping make new products with less environmental impact.
How IPG’s Pelletizing Equipment Works
At IPG, our equipment is designed to change the plastic recycling game. As leaders in plastic pelletizers, we use the latest technology. This ensures efficiency and quality in our pellets.

Challenges in the Plastic Recycling Industry
The plastic recycling industry faces many challenges. These affect its efficiency and effectiveness. Understanding these challenges is key to improving recycling rates and reducing environmental harm.
Contamination Issues
Contamination is a big challenge in plastic recycling. Mixing non-recyclable plastics with recyclable ones or having food residue, chemicals, or adhesives can mess up the recycling process. Food residue is a major contaminant that can ruin entire batches of recyclable material.
Economic and Logistical Hurdles
The industry also faces economic and logistical challenges. Market prices for recycled plastic can change, making recycling hard to do at times. Collecting, transporting, and sorting plastic waste across different areas is also a big challenge.
| Type of Plastic Packaging | Recyclability | Common Challenges |
| Single-material packaging (e.g., PET bottles) | High | Contamination with food residue |
| Multi-layer or multi-material packaging | Low | Difficulty in separation and processing |
| Plastic packaging with adhesives or labels | Moderate | Adhesives and labels can contaminate recyclables |
At IPG, we design our equipment to help solve some of these problems, especially with mixed plastic streams. We think solving these challenges needs teamwork from manufacturers, recyclers, consumers, and equipment providers like us.
