How to Sort Plastics: WESORT Advanced Plastic Sorting Solutions

　　Plastic waste recycling is one of the most pressing challenges in today’s sustainability-driven world. Proper plastic sorting ensures high-quality recycled materials, reduces environmental impact, and improves profitability for recycling businesses. While manual sorting is still common, advanced technologies like plastic color sorter machines are transforming the recycling industry. In this article, we explore how plastics are sorted by type, color, and size — and why WESORT Plastic Color Sorter Machines are the best solution for recyclers worldwide.

　　Sorting Plastics by Type

　　The first step in recycling is separating plastics from general waste. This process can be manual or automated.

　　Manual Sorting: Workers identify plastic waste, removing non-recyclable items like PVC.

　　Automated Sorting: Using sensors, optical scanners, and infrared detection, machines can identify different polymers such as PET, HDPE, PP, and PVC, and separate them with pneumatic systems.

　　👉 Note: At this stage, plastic color sorters are not directly applied. Instead, optical and NIR technologies handle polymer-type separation. The plastic color sorter becomes crucial after plastics are shredded into flakes, where precise color and impurity sorting ensures high-quality output.

　　Sorting Plastics by Colour

　　Color separation is where the plastic color sorter machine plays the most important role. Each plastic type contains different dyes and additives, and consistent color separation is essential for producing high-grade recycled materials.

　　Spectrophotometers: Used in lab testing to measure accurate color values.

　　Optical Sorting Machines: High-resolution sensors detect even subtle color variations in shredded plastic flakes.

　　Here is where WESORT Plastic Color Sorter excels:

　　✅ AI-powered algorithms achieve up to 99.8% sorting accuracy.

　　✅ Removes colored flakes, labels, caps, impurities, and foreign particles.

　　✅ Ensures PET flakes, HDPE, and PP achieve maximum purity, ready for reprocessing into new products.

　　Sorting Plastics by Size

　　Before the color sorting stage, plastics are usually shredded or granulated into smaller flakes. This step increases surface area and improves further separation.

　　Shredding & Granulation: Breaks plastics into uniform particles.

　　Washing & Density Separation: Removes dirt, paper, and glue while separating plastics by floatation methods.

　　Optical Sorting with Plastic Color Sorters: Final purification step, where flakes are separated by color, material consistency, and surface defects.
