Green Chemicals: Combining & Refining High-Purity Chemicals without Environmental Destruction


Green Chemicals Division

+81-3-5822-6182


We offer solutions for increasing and restoring value to solvents.

In our Green Chemical business, we refine chemicals to high levels of purity and recycle solvents.

The Green Chemicals division uses techniques for synthesis, distillation and purification developed over the last fifty years to recover waste solvents and volatile organic compounds (VOC) at our 6,500t/month capacity distillation plant.
In response to the increasing demand of high purity solvents that are used in manufacturing of flithium ion battery materials or electronic materials, in April 2013, we completed new AWAJI PLANT in Awaji-shi of Hyogo.
By distilling and purifying these recovered chemicals using advanced recycling technology, we regenerate solvents and other chemicals to their virgin state.
We also market various synthetic products made with our unique synthesis technologies.
