Food Waste Odor, No More~

Suwon City plans to begin construction in February to install a vertically-stacked cylindrical fermentation unit (sealed type) at the food waste resourceization facility in Godsaek-dong to resolve resident inconvenience and complaints caused by food waste odor issues.

According to the city on the 10th, it revealed plans to complete the cylindrical fermentation unit by May, investing a total project cost of 855 million won to process 50 tons per day.

The cylindrical fermentation unit pursued by the city is a completely sealed steel structure that prevents odors from leaking out during the fermentation process for food waste composting, and is characterized by easy deodorization work.

The treatment process of the cylindrical fermentation unit involves a total treatment cycle of 36 days, including a 15-day fermentation process, with 2 of the 3 fermentation units introduced to comply with environmental ministry standards serving as fermentation tanks and 1 serving as a maturation tank, producing stable compost.

With the detailed design of the fermentation unit completed on the 9th, the city plans to select a constructor through public bidding by the end of this month and begin fermentation unit construction next month.

Once the cylindrical fermentation unit is completed, the city expects to resolve the food waste odor problem that has caused inconvenience to residents in the West Suwon area, as well as produce fully-matured compost to supply to farms growing crops and fruit trees, thereby achieving food waste resourceization and environmental improvement effects.

Yu Wan-sik, head of the Sanitation Administration Division, said, "The operation of the cylindrical fermentation unit will bring an effect of removing more than 80% of odors generated from the existing food waste treatment process," and added, "It will contribute to resolving resident inconvenience and addressing environmental issues."
