Hybrid (NET No. 363)  
It took almost 4 years to develop Exen’s hybrid odor control system, which is aimed for the global market, through the MOE’s technology development project. This world-class odor control system has been accredited as a New Excellent Technology. In particular, this system is composed of the simplest and most innovative techniques such as immobilization based on microorganisms and yeast, malodor monitoring, self-diagnosis and active control, a combination of scrubbers for pretreatments, and the biofilter.
