We would like to introduce our "Reuse and Recycling Business." With the motto of "Do not bury, do not burn, do not discharge," we have equipped ourselves with various facilities to promote the reuse of waste and have obtained the necessary permits. By utilizing our core technologies of "separation and high purity" and "mixing," we are contributing, albeit modestly, to a circular economy by advancing the recycling of waste in the following four key areas. 【Four Key Areas】 ■ Distillation recycling of organic solvents ■ Recycling of precious metals and rare metals ■ Separation and recovery of mixed acids through solvent extraction ■ Mixing, emulsification, and thermal recycling *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our company's "separation and recovery of mixed acids." Etching processes using mixed acids are widely used in the manufacturing of liquid crystals and semiconductors, and at the same time, used mixed acid wastewater has been generated. Traditionally, a portion of this mixed acid wastewater has been used for pickling in steel mills; however, the majority has not been effectively utilized, as it has been neutralized with large amounts of alkali and then incinerated. In response, our company established a technology to separate mixed acid wastewater and recover it as a single acid, in collaboration with Kansai University. The recovered acid can now be effectively utilized as a resource through reuse and recycling. [Features] - Established technology to separate mixed acid wastewater and recover it as a single acid - Recovered acid can be effectively utilized as a resource through reuse and recycling - Recognized as a "device for acid recovery from mixed acid wastewater using solvent extraction" by the Japan Science and Technology Agency *For more details, please refer to the PDF document or feel free to contact us.

Our company separates and recovers rare metals contained in electronic component substrates, catalysts used for exhaust gas purification, and waste from the agricultural and pharmaceutical sectors. In addition to conventional recovery methods such as carbonization, ashing, acid dissolution, and resin adsorption, we utilize our expertise in distillation and low-cost, energy-efficient solvent extraction methods, employing unique recovery techniques developed through the recycling of organic and inorganic chemicals and solids. This allows us to recover from difficult-to-handle waste and trace amounts of contained substances that major companies do not address. 【Features】 ■ Separation and recovery of rare metals ■ Capable of recovering from difficult-to-handle waste and trace amounts of contained substances *For more details, please refer to the PDF document or feel free to contact us.

The distillation recycling of organic solvents is the recycling technology that our company excels at the most. By leveraging our advanced technology and extensive know-how, we can transform organic solvents emitted from various industries into products tailored to our customers' needs. Our company possesses numerous distillation facilities and has obtained patents for our unique distillation technology to carry out resource recovery according to the state of solvent waste and the characteristics of organic solvents.

Our company has established a technology to separate mixed acid waste and recover it as a single acid, initiated through joint development with Kansai University. The recovered regenerated phosphoric acid is used as a nutrient source for wastewater treatment, as fertilizer raw material, and as a chemical raw material. We own equipment that allows for concentration, and we can adjust it to your desired concentration! *For more details, please refer to the PDF materials or feel free to contact us.
