We strive to contribute to the utilization of beneficial processes for clients, humanity and nature. We hope that our invention and innovation will change the earth better.

EZER will investigate and develop the technology for Membrane, Catalyst, and Biofuel. Furthermore, we are to search for new ways that Membrane and Catalyst may be applied to the existing processes.

Particularly in regard to Biofuel, we are currently making an effort to produce biobutanol from biomass. We have already completed the pilot plant construction. We are developing and scaling up into a demo plant of 1.5 MTD, the world’s first bio-butanol production process which contains solid handling, microbial reaction system, membrane separation and sulfuric acid treatment.

Along with fulfilling the above urgent tasks, our capability would not be limited to categories above. We ceaselessly expand our horizon into areas not touched by others before. We explore even the smallest possibilities to pave the way for unprecedented technological innovation. The table below shows that we have accomplished technical innovation in energy efficiency and process improvement.
