Abstract
Recycled resin is produced by a method including a dismantling/recovery step of dismantling products containing resin moldings and recovering the resin moldings, a removal step of removing unwanted matter including metal components from the resin moldings, a sorting step of discriminating the materials of the resin moldings, and a crushing step of crushing the resin moldings. The method further includes, prior to the crushing step, detecting the metal components, and, after the crushing step, separating out and thus removing metal remaining in crushed material.
Claims9
A method for producing recycled resin comprising:
- dismantling a product containing a resin molding and recovering the resin molding;
- removing unwanted matter including a metal component from the resin molding;
- detecting whether there is any remaining metal component in the resin molding subsequent to the removal of the unwanted matter;
- upon the detection of a remaining metal component in the resin molding, repeating said removing unwanted matter to remove the remaining metal component;
- crushing the resin molding into crushed material;
- and
- separating and removing metal remaining in the crushed material.
A method for producing recycled resin comprising:
- a dismantling/recovery step of dismantling a product containing a resin molding and recovering the resin molding;
- a removal step of removing unwanted matter including a metal component from the resin molding;
- a sorting step of discriminating a material of the resin molding;
- and a crushing step of crushing the resin molding;
- wherein the method further comprises a metal detection step, before the crushing step, for detecting the metal component, and a metal separation step, after the crushing step, for separating and removing metal remaining in crushed material obtained in the crushing step;
- and
- wherein the sorting step further includes a fire resistance testing step of measuring fire resistance of the resign molding.
