This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%).An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.
