Title: Hiroshi Kumamoto: Innovator in Counterweight Recycling

Introduction

Hiroshi Kumamoto is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of recycling, particularly in the development of counterweights. His innovative approach not only enhances workability but also promotes environmental conservation.

Latest Patents

Kumamoto holds a patent for a "Counterweight and method for recycling the same." This invention provides a counterweight that is capable of reducing manufacturing costs while achieving excellent workability. The method utilizes a metal portion contained in slag produced during the iron-making process or in residue from waste treatment furnaces as a weight material. The recycling method includes several steps: removing the outer shell of a used counterweight, crushing and cutting the filler containing the metal portion, and separating the processed products into high-specific-gravity substances and low-specific-gravity substances. The high-specific-gravity substances are then used as weight materials for newly manufactured counterweights.
