Introduction

Katsuhito Kawamura is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of materials recovery, particularly in the recycling of metallic tin from electroplating sludge. His innovative methods have implications for both environmental sustainability and resource efficiency.

Latest Patents

Kawamura holds a patent for a method aimed at recovering metallic tin from electroplating sludge. This method involves leaching the sludge with water at a pH of 7 or less, followed by the separation of iron-containing sludge. The process alkalifies the filtrate obtained from the first separation step to deposit tin-containing sludge. This tin-containing sludge is then separated and recovered, redissolved in an alkaline solution, and subjected to electrolytic reduction. The result is the recovery of high purity metallic tin at a high yield, along with the recovery of other materials for reuse, all while maintaining an environmentally friendly operational process. He has 1 patent to his name.
