How does the PS/ABS Recycling Line work?


PS/ABS Classification System for Recovery Lines

Different PSABS materials have other uses and properties and must be carefully sorted before entering the recycling line. The PSABS recycling line utilizes a sophisticated sorting system to ensure that a wide range of materials are correctly processed and recycled.

The PSABS Recycling Line’s sorting system is based on the following criteria:


  • Sorting PSABS Recycling begins with a distinction based on its material, such as Food Grade PSABS, General Purpose PSABS, and Impact Resistant PSABS.


  • PSABS recyclables are sorted according to color, as different colored materials may have different properties and uses.

Level of contamination:

  • The sorting system will also consider the level of contamination of the PSABS recyclate, such as whether it contains paper, metal, or other items.

The sorting process involves the following steps:

Visual Inspection:

  • First, staff will visually inspect and sort the PSABS recyclables according to the above criteria.

Machine sorting:

  • The recyclables are then passed through machine sorting equipment that utilizes optical sensors and conveyor belts for more accurate sorting.

Manual Sorting:

  • Finally, staff will perform manual sorting after machine sorting to ensure accuracy and quality.

Proper sorting of PSABS recovery is crucial as it:

  • Ensures the material is appropriately processed for recycling, ensuring the highest quality recycled product.
  • Reduces the risk of contamination and prevents foreign material from entering the regeneration process.
  • Increases recycling efficiency and maximizes the value of PSABS.


Recycling treatment of PSABS recovery line

The processing stage of a PSABS recycling line is a critical step in replacing collected PSABS with reusable raw materials. During this stage, the recycled material undergoes a series of processing and handling procedures, including:

Crushing and Grinding:

  • The recycled PSABS is crushed into small pieces and ground into fine fragments.

Cleaning and Floating Sorting:

  • The fragments are successively cleaned and floated for sorting to separate the PSABS fragments from the rest of the reconstruction.

Drying and Dewatering:

  • The separated PSABS scrap is dried and made into small pellets through a dewatering machine.

In the final stage of the recycling process, the PS/ABS pellets are graded according to their grading and quality. These pellets will be initialized to manufacture raw materials for new PS/ABS products, such as tableware, packaging materials, or construction materials. Through the regeneration process, the PS/ABS Recovery Line can effectively convert waste emissions into valuable resources and promote sustainable use.

High-tech sorting technology for PSABS recovery lines

The compatibility of PSABS recovery lines relies on high-tech sorting equipment to accurately classify different types of PSABS products. This equipment utilizes advanced sensors and sorting technology to ensure the quality and purity of the recovered materials and enhance the recovery efficiency.

Optical Sorting:

  • Optical detectors are used to remove color and texture differences on the surface of PSABS products and differentiate the gain of different colors of PSABS.

Laser sorting:

  • Laser technology detects the densities of PSABS materials, separating high-density PSABS from other low-density PSABS.

Electrostatic sorting:

  • According to the different characteristics of PSABS particles charged, the electrostatic field sorting out various types of PSABS is used instead.

Flotation sorting:

  • PSABS particles are put into a solution with different densities; the high-density particles will sink to the bottom while the low-density particles will float on the surface, realizing the sorting.

Through these high-tech sorting techniques, the PSABS recovery line can effectively recover damages, such as paper, plastic, and other materials, to ensure the degree of damage to the recovered materials and create favorable conditions for the subsequent processing of regeneration.


Environmental Efficiency Decoding of PS/ABS Recovery Lines

PS/ABS restoration lines play an important environmental role, effectively reducing negative ecological impacts. Firstly, PS/ABS restoration helps to reduce emissions from landfills and incinerators, reducing the impact on the ecosystem. Emission reduction is one of the critical measures to protect the environment, and PS/ABS recovery lines play a driver’s role in this.

Secondly, PS/ABS recovery saves valuable resources by reducing the need to produce plastic products. By recovering for reuse, we can reduce our dependence on non-renewable resources such as oil and reduce the environmental footprint of the extraction and production process. Additionally, PSABS recovery helps by saving energy and water, as recycling PS/ABS requires fewer resources than producing new plastics.

In addition, PS/ABS recovery contributes to the climate change component by reducing greenhouse gas emissions. The production of new plastics produces large amounts of greenhouse gases, and restoration for reuse reduces these emissions, helping to minimize the impact of climate change. At the same time, PS/ABS restoration also promotes resource recycling and prevents waste of valuable materials, which has a definite effect on environmental sustainability.
