We would like to introduce a case where we implemented our distillation equipment for in-house solvent recovery and purification. Before the implementation, we relied on a waste solvent recovery company for collection and purification, which incurred costs, and we had to adjust production based on the timing of waste solvent collection. Therefore, we conducted distillation tests using waste solvent samples and evaluated the results. We then introduced a recovery and purification system that reflected those results, allowing us to purify waste solvents in line with our production schedule. 【Case Overview】 ■Challenges - We were incurring costs by relying on a recovery company for waste solvent collection and purification. - The cost of purified solvents was nearly that of new ones. - We needed to adjust production based on the timing of waste solvent collection. ■Results and Effects - We were able to purify waste solvents in accordance with our production schedule. - We significantly reduced the amount of new solvents purchased. *For more details, please download the PDF or feel free to contact us.
