Abstract
Valuable metals contained in Automobile Shredder Residue are intricately entwined with resin and fiber, which cannot be separated or recovered using existing separation technology. For this reason, these metals are currently unutilized without being recycled.
Not only for solving this problem, but also for an energy-efficient transformation of resin into alternative fuels to coal, the application of Low-temperature embrittlement technology to this treatment system was studied. In addition, necessary crushing and separation technologies were studied on a commercial scale system to effectively recover valuable metals from embrittled products.
As a result, the following three technologies were developed: thermal embrittlement technology that produces embrittled products with a high residual calorific value and good crushability, crushing technology that provides the ability to control particle size and has the toughness needed to deal with hard metals, and separation technology that makes it possible to recover valuable metals with high efficiency.
