Hyundai Construction Develops Korea's First Odor Management System 'HOMS'

[Asia Economy Reporter Yuri Kim] Hyundai Engineering & Construction announced on the 24th that it has developed 'HOMS (Hyundai Odor Management System),' the first odor management system in Korea for environmental infrastructure facilities such as food waste treatment plants and sewage treatment plants.

HOMS is an odor management system that monitors odor concentration in real-time inside environmental infrastructure facilities and along site boundaries, preventing the spread of odors to surrounding areas. It is a "ventilation control system for odor generation sites using complex odor information," for which a patent application was completed in June.

Existing complex odor sensors measure individual odor-causing substances with dedicated sensors and then combine these to represent complex odors. To measure hundreds of thousands of odor-causing substances individually, many expensive sensors are required, making it difficult to measure various odors inside and outside the facilities.

The newly developed HOMS by Hyundai Engineering & Construction has its own algorithm that expresses complex odors based solely on measurements from five sensors in each room: temperature, humidity, ammonia, hydrogen sulfide, and volatile organic compounds. Since multiple dedicated sensors for individual odors are unnecessary, it significantly reduces costs compared to existing complex odor sensors and enables monitoring of multiple indoor spaces at the same cost.

HOMS applies differential pressure control technology. Utilizing the property that air flows from high pressure to low pressure, it increases air pressure in rooms where no odor is generated and lowers air pressure in spaces where odor occurs, ensuring that odors are not released outside and are smoothly captured.

HOMS was pilot-applied at the 'Chungju Food Waste Bio Energy Center,' which Hyundai Engineering & Construction completed in 2016 and participates in as a research institution. The facility, covering 100,716 square meters and capable of processing 80 tons of food waste per day, was used to verify the odor management efficiency of HOMS, according to the company. Plans are underway to expand its application to various environmental infrastructure facilities.

A representative from Hyundai Engineering & Construction’s Technology Research Institute said, "As the importance of preventing and managing odor pollution grows, HOMS developed by Hyundai Engineering & Construction will be a good solution. We will continue to lead efforts to establish systems that prevent and manage environmental pollution in advance through ongoing research."
