Aluminum-Plastic Pyrolysis Plants In Vietnam

To address the client’s dual requirements for handling medical aluminum-plastic composites and automotive waste tires, we engineered a multi-feedstock, semi-continuous pyrolysis system. The customized solution comprised two 15-ton-per-day (TPD) pyrolysis reactor lines, running in parallel to maximize daily throughput and ensure operational redundancy.

First, the system utilizes a hydraulic auto-feeder designed to handle both shredded tires and compressed aluminum-plastic bales without requiring extensive manual pre-sorting. Inside the rotary reactor, the materials undergo oxygen-free thermal degradation at precisely controlled temperatures between 280°C and 320°C. For aluminum-plastic composites, the plastic polymers vaporize into oil gas, while the solid aluminum foil remains intact for highly profitable post-process recovery. When the client switches the batch to waste tires, the rubber similarly vaporizes, leaving behind carbon black and scrap steel wire.

To ensure superior yields and exceptional safety, both plants were equipped with a highly efficient multi-stage tubular cooling system that rapidly condenses the oil gas into premium fuel oil. A critical component of this tailored solution was the environmental control infrastructure. We integrated a specialized syngas recycling loop that routes non-condensable combustible gases back to heat the furnace, drastically reducing external fuel consumption and lowering overhead costs.

Furthermore, a state-of-the-art flue gas purification system—featuring water spray towers and activated carbon adsorption—was installed to ensure all emissions strictly comply with Vietnam’s national environmental protection standards. This closed-loop design successfully transformed the client’s waste liability into a sustainable, compliant energy enterprise.
