AI Technical Summary

Technical Problem

The existing recycling methods for building materials like exterior urethane panels incur high costs due to sorting, crushing, and transportation, and the separation of valuable materials from waste is inefficient and complicated.

Method used

A recycling method that involves scrapping exterior urethane panels directly into an electric furnace without separating waste and valuable materials, allowing urethane to be decomposed at high temperature, leaving iron to be rolled and formed into steel, which is then reused as building materials.

Benefits of technology

This method reduces costs associated with sorting and transportation, enables efficient recycling of valuable materials, and establishes a circular economy by reusing recycled steel as building materials, contributing to sustainable resource management.

Abstract

To provide a method for efficiently recycling a recycle target having valuables and wastes.SOLUTION: A recycle method includes a first step of collecting and scrapping an object to be recycled before scrapping that includes a valuable and waste, a second step of charging the object to be recycled after scrapping of the first step into an electric furnace without separating the waste and the valuable, and a third step of taking out the valuable object remained in the second step by removing the wastes from the object to be recycled and rolled the valuable to form a recycled product.SELECTED DRAWING: Figure 1
