Characteristics of volatile compound emission and odor pollution from municipal solid waste treating/disposal facilities of a city in Eastern China

Abstract

Transfer station, incineration plant, and landfill site made up the major parts of municipal solid waste disposal system of S city in Eastern China. Characteristics of volatile compounds (VCs) and odor pollution of each facility were investigated from a systematic perspective. Also major index related to odor pollution, i.e., species and concentration of VCs, olfactory odor concentration, and theoretic odor concentration, was quantified. Oxygenated compounds and hydrocarbons were the most abundant VCs in the three facilities. Different chemical species were quantified, and the following average concentrations were obtained: transfer station, 54 VCs, 2472.47 μg/m; incineration plant, 75 VCs, 33,129.25 μg/m; and landfill site, 71 VCs, 1694.33 μg/m. Furthermore, the average olfactory odor concentrations were 20,388.80; 50,677.50; and 4951.17, respectively. The highest odor nuisance was detected in the waste tipping port of the incineration plant. A positive correlation between the olfactory and chemical odor concentrations was found with R = 0.918 (n = 15, P< 0.01). The result shows odor pollution risk transfer from landfill to incineration plant when adopting thermal technology to deal with the non-source-separated waste. Strong attention thus needs to be paid on the enclosed systems in incineration plant to avoid any accidental odor emission.

Effects of intermittent chemical dosing on volatile sulfur compounds in sewer headspace

“…It might be attributed to the degradation of sulfur-containing amino acids such as methionine and cysteine in wastewater, which was usually decomposed to VOSCs by deamination and demethylation. The result in this study was constant with the previous study which showed VOSCs were the highest concentration of the detected VSCs[14]. In Phase II, the intermittent addition of FeCl 3 , H 2 O 2 , and KNO contributed to significant decreases in the VSCs concentrations in the first three days.The total VSCs in the headspace decreased from 22,000-24,500 µg/m 3 to 6,200-7,500 µg/m for ferric iron and nitrate intermittent addition, from 20,000 µg/m 3 to 9,800 µg/m 3 for H 2 O 2 addition.…”

“…The theoretical odor concentration (ThOC), which was widely used to determine the main odorous substances [14], was used in this study to assess volatile compounds' pollution potential and to identify the main odorous compounds in the sewer system. The sulfur compounds include…”

Chemical Recycling of Plastic Waste: Comparative Evaluation of Environmental and Economic Performances of Gasification- and Incineration-based Treatment for Lightweight Packaging Waste

“…Incineration reduces waste volume, weight, and pollution potential while generating electricity and/or heat as useful products [18]. Additionally, the extraction of minerals as construction materials and "pure" metals make it an attractive alternative to landfilling [18][19][20][21][22]. However, the downside of incineration is that via the incineration process potentially recyclable carbon-containing LWP fractions such as plastics and cardboard will be converted into greenhouse gas (GHG) emissions.…”

Investigation and Evaluation of Flue Gas Pollutants Emission in Waste-to-Energy Plant with Flue Gas Recirculation

“…In China, the composition of MSW is complex, being primarily composed of kitchen and building waste, textiles, plastics, and metals [11,12]. The components and calorific value of MSW are related to the developing level of the economy.…”
