Automotive Shredder Residue (ASR) is an inevitable by-product of vehicle dismantling and metal recycling. It typically consists of plastics, rubber, fibers, foams, coating fragments, and small amounts of metal, with a complex composition and large density differences. If disposed of directly in landfills, it not only occupies land but may also cause environmental pollution. Converting ASR into Solid Recovered Fuel (SRF) provides an effective way to utilize these materials as a resource, creating economic value for enterprises.
Challenges in ASR Processing
Although ASR is combustible, its processing faces three major technical challenges:
Complex composition and difficult separation
ASR contains various plastics, rubber, and fibers that are tightly interwoven, making separation inefficient and limiting fuel purity.
Irregular material shape and inconsistent particle size
ASR often consists of lightweight, flexible, and sheet-like materials. Uneven particle sizes after shredding can impact the efficiency of downstream separation processes and the quality of the final SRF product.
High impurity content and equipment wear
ASR often contains metal fragments, glass, and coating residues, which can accelerate cutter wear, require frequent maintenance, and affect production continuity and operating costs.
GEP ECOTECH's Solution
To address these challenges, GEP ECOTECH introduced an ASR pre-treatment solution centered on a four-shaft shredder (ASR shredder). This system has been successfully implemented at a large automotive dismantling facility in southern Taiwan. The solution efficiently converts ASR into SRF, not only resolving residue accumulation but also achieving resource recovery, delivering both environmental and economic benefits.
Key Advantages
Powerful shredding and wide adaptability
The four-shaft structure provides high torque and continuous cutting, efficiently handling complex, flexible, and interwoven materials. It ensures smooth feeding and reduces the risk of blockages.
Consistent particle size for improved separation
The shredded output can be controlled to approximately 30 mm, producing uniform particles. This enhances the efficiency of downstream separation and improves the overall quality of SRF production.
Stable operation and durable design
Equipped with wear-resistant cutters and a robust structure, the machine can operate continuously for long periods, reducing maintenance frequency and ensuring production stability and reliability.
ASR recovery is an inevitable trend in the automotive dismantling industry. With extensive experience and customized solutions, GEP ECOTECH helps clients efficiently convert ASR into usable energy. If you have similar needs, please feel free to contact us for professional solutions.
