A field-scale evaluation of the removal of odorous gases by a plant material-based deodorant

The composting process emits various volatile chemicals, including hydrocarbons, nitrogen compounds, sulfur and oxygenated compounds. These gases must be removed to avoid atmospheric pollution. Spraying extracted materials from plants, such as tea tree oil, onto the surface of a windrow is novel odor-reduction technique for treatment gaseous emissions facilities. In this study, plant material-based deodorant mixture coconut, lemon, essential oils was sprayed directly with spraying frequency three times day. Odorous compounds were measured before after evaluate performance deodorant. After spraying, ammonia concentration decreased 10,000 7,000 μg/m 3 . There large decline in alcohols, aromatics, carbonyls 30,612, 12,270, 5,138 4,965, 4,669, 2,253 , achieving efficiencies 83%, 62%, 56%, respectively. removal terpenes, fatty acids, lower than former, falling within range 24%–36%. theoretical total odor 23,757 at beginning 13,056 end, revealing that most bad smell had been eliminated.
