“…From the viewpoints of public health and air quality, the exhausts from rendering plants must be treated using a novel technology of high treatment efficiencies for reducing the long-standing complaints from community residents for the odors (Vieira et al, 2016;Sazakli and Leotsinidis, 2021;Sazakli et al, 2022). Chemical oxidation technology has been developed and widely applied for abating industrial odors over 30 years, especially for the odor emissions from various biological sources (Cheremisinoff, 1992;Capelli et al, 2019;Chou, 2009Chou, , 2019Wysocka et al, 2019;Zarra et al, 2019;Senatore, 2021). However, aldehydes emitted from the rendering processes have been seldom treated by a chemical oxidation system using hydrogen peroxide as an oxidant.…”

Rendering plants treat dead livestock and produce grease and bone meal. In a rendering plant, the cooking and drying processes are the main sources of odor emissions. Non-fresh dead livestock reduce the performance of odor control devices, and in Taiwan, the treatment facilities in a rendering plant mostly are operated in a batch feeding, which causes volatile organic compound (VOC) emissions in the exhausted gas, that always caused complaints from the nearby neighborhood. This study used respectively ozone and hydrogen peroxide to evaluate the removal efficiencies of pentanal, hexanal and toluene those are common VOCs in the rendering exhaustion. Experimental results indicated that ozone could not effectively reduce aldehydes and toluene, and the residual ozone remaining in the exhaust gas is a secondary air pollutant and irritate the human respiratory tracts. Oppositely, hydrogen peroxide effectively removed pentanal as a feasible VOC treatment oxidant by adding into a contact reactor. When the pentanal exhaustion concentration from the rendering process was around 36.23 ppm in the flue with the flow rates from 100 to 250 Nm 3 min -1 , the reaction rate constant of pentanal for the first-order reaction by aqueous hydrogen peroxide of 1,000 mg L -1 was obtained as 0.536 1 s -1 , and then the pentanal reduced to 0.68 to 2 ppm. Based on the simulation using the Gaussian dispersion model, the concentration ranges of pentanal in the exhausted stream resulted in the pentanal emission rate lower than 0.01 g s -1 , which no longer causes surrounding residents' complaints.

“…Different techniques, such as field inspection, electronic noses, and portable olfactometer, may be used to determine odor concentrations in the ambient air. [ 21,22 ] There are several standard olfactory methods for measuring odor concentrations, such as the dynamic olfactometry method and the triangle odor bag method. [ 23 ] These methods have advantages and disadvantages, and the choice of methodology depends on the particular aims and needs of the research.…”

The main goal of the present study was to highlight how crucial odor evaluation methods may be for raising the general standard of living in a region. For this, the dispersion of odor concentrations detected by an olfactometric method in an area of Kocaeli, Turkey, where odor problems are frequently experienced, was investigated using the AERMOD atmospheric dispersion modeling system. According to the findings of the olfactometric measurement, the mean odor concentrations in the industrial area was high at 1342 OU m–3, while in the residential areas the values were lower, at 578 OU m–3 within the selected study area. As a result of the modeling study, the maximum odor concentration was 2081 OU m–3 at the 1 h. The model also showed that the coordinate points where the maximum odor concentration was observed changed with time, and that the concentrations recorded at the 1 h may decrease by as much as 88%–91% at the 24 h. In the study, a survey was also conducted to identify possible effects of odor pollution on people. The survey findings showed a statistically significant difference (p < 0.05) between the two areas (industrial and residential) for seven variables of a total 28. We suggest that measuring odor concentrations, modeling their distribution, and conducting surveys are effective methods when managing the urban planning process.

“…Firstly, as outlined by [66], public engagement in odour pollution can provide further knowledge about it, through the high numbers of "sentries". Collecting several citizen complaints about odours could be an advantage to identify efficiently the potential receptors and pathways of the gas pollutants, with reference to a specific industrial installation.…”

The potential of citizen science to address complex issues has been recognized since the 1990s. However, the systematic integration of public opinion in research has been developed only recently, thanks to the spread of questionnaire web-based surveys and artificial intelligence techniques for data elaboration. Starting from this point, we decided to investigate the literature published in Scopus during the decade 2013–2023, regarding citizen science applications for environmental purposes. More specifically, the focus of our study was to evaluate citizen science’s benefits and limitations for managing odour emissions in national industrial plants, as well as to discuss the potential integration of a participatory approach in such a field. In fact, according to European Directive 2010/75/EU, the integrated environmental permits released to reduce industrial pollution should also encourage strong public participation. In this systematic review we first applied the principles of PRISMA methodology to select the most significant papers. Then, we discuss the results of 14 publications, through bibliometric statistics and meta-analysis. Only three of them were discovered to have a specific focus on odour emissions. Overall, we pinpointed the main advantages and limitations of citizen science applied to odour pollution management, to open the door for further research.
