He has made significant contributions to the field of materials recovery, particularly in the efficient extraction of metallic tin from electroplating sludge. His innovative methods not only enhance recovery rates but also promote environmental sustainability.

Latest Patents

Ishikawa 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 includes alkalifying the filtrate to deposit tin-containing sludge, which is then separated and recovered. The tin-containing sludge is redissolved in an alkaline solution, leading to electrolytic reduction. This technique allows for the recovery of high-purity metallic tin at a high yield, while also enabling the reuse of other materials without polluting the operational environment. He has 1 patent to his name.
