Nationwide & Overseas
Our remediation track record to date
An excerpt from our oil and VOC remediation record across all 47 prefectures and overseas: facility type, medium, contaminant, method and region.
54 sites shown (26 prefectures plus Taiwan).
This is only an excerpt of our track record. A fuller list of remediation projects is being prepared.

Featured Case Studies
Representative cases
Nakhodka Oil Spill
Contributing to the cleanup of the Nakhodka heavy oil spill
In one of Japan's largest marine pollution incidents, caused by heavy oil that leaked from the Russian tanker "Nakhodka" in January 1997, the remediation effectiveness of our bioremediation was demonstrated.
Waste Oil Cleanup in Rice Fields
Breaking down waste oil that contaminated rice fields with the power of microbes
It was demonstrated that our bioremediation could remediate waste oil that, due to an accidental discharge by an industrial waste contractor, had spread across rice fields and withered the rice.
