SEOUL -- A state nuclear energy research institute has commercialized an odor-reducing technology for livestock farms. The technology involves a particle accelerator that shoots electron beams to disintegrate substances that create bad smells.

Fumes of putrid-smelling gases produced at animal farms contain harmful substances such as ammonia, hydrogen sulfide and methanethiol. Also, it is harder to filter and purify gases at farms because they have a higher rate of organic compounds than gases created at homes or industrial facilities.

Normally, water and chemicals are used at farms to dissolve or wash away such harmful substances. However, such methods are not very efficient and require a cleaning process including the disposal of liquid wastes.

The Korea Atomic Energy Research Institute (KAERI) said in a statement on September 29 that the research institute has transferred the electron beam-based odor-reducing technology to Taesung, a domestic company with environmental monitoring and odor tracking technology, for commercialization.

The technology was developed as part of a project by South Korea's environment ministry to tackle one of the country's hard-to-solve problems. Quarrels and legal conflicts often take place between livestock farms and nearby residents due to bad smells.

KAERI said that its new electron beam technology can destroy in-air substances that cause bad smells. Particle accelerator operators will check the density of substances in real-time and control the strength of electron beams. About 95 percent of bad smells can be reduced using the particle accelerator.
