“…The authors indicated acetic acid, butyric acid, valeric acid, isovaleric acid, and dimethyl sulfide as the most odor-generating substances. Wiśniewska et al (2019Wiśniewska et al ( , 2020 researched the emission of odorants and odors from 6 MBT plants in Poland, which had the installation for anaerobic decomposition (fermentation) of the organic matter contained in mixed municipal waste (Wiśniewska 2020a, Wiśniewska 2020b, Wiśniewska and Szyłak-Szydłowski 2021, Wiśniewska et al 2019. The conducted research concerned mainly the analyzes of substances such as VOC (measured values of a dozen or so ppm on average), ammonia (a dozen or so ppm on average), hydrogen sulfide (not more than a few ppm), dimethyl sulfide, methyl mercaptan (usually below one ppm) and analyzed the concentration of odors using field olfactometry.…”

“…This stems from the fact that municipal waste generated by people contains organic waste (Alwaeli 2015, den Boer 2010, Burnley 2007, Chen 2018, which undergoes biological degradation, i.e., biodegradation, which is the main cause of the emission of odors and odorants to the air (Bruno et al 2007, Sonibare et al 2019. Biodegradation can occur both under aerobic (He et al 2020) and anaerobic (Wiśniewska 2020a) conditions. The processes related to the management of municipal waste containing organic fractions, which can generate odors, include: waste collection at residential areas (Liu et al 2020, Shi et al 2020, Tan et al 2017, transport (Tan et al 2017, waste transfer stage at transfer stations (Chang et al 2019 and the activities related to waste management at mechanical-biological treatment (MBT) plants and biological waste treatment plants (Colón et al 2017, Hou et al 2013, Kulig and Szyłak-Szydłowski 2016, Sironi et al 2006, including aerobic stabilization and anaerobic stabilization technology, in the case of mixed municipal waste treatment, as well as composting and anaerobic digestion, in the case of selectively collected bio-waste (Mustafa et al 2017, Sánchez--Monedero et al 2018, Sironi et al 2007, Wiśniewska et al 2019, thermal treatment of waste in waste incineration plants (Guo et al 2017, Çetin Doğruparmak et al 2018 or landfilling (Duan et al 2021, Zhang et al 2021.…”

Waste management faces more and more serious challenges, especially given the growing amount of municipal waste generated in Poland and the resulting environmental impact. One of the significant environmental aspects of waste management is the emission of odorants and odors. Taking into account the odor problem, the majority of municipal waste generated is being collected as mixed waste (62% of municipal waste), which by weight contains approximately 32.7% of kitchen and garden waste. These organic fractions are mainly responsible for the emission of odor and odorants. Those substances can be emitted at every stage: from the waste collection at residential waste bins, through transport, waste storage, and transfer stations, up to various respective treatment facilities, i.e., mechanical-biological waste treatment plants, landfills, or waste incineration plants. The gathered data during the study showed that it is necessary to increase the share of different waste management methods, i.e., recycling, composting, or fermentation processes rather than landfilling to meet all necessary regulations and to fulfill provisions of the waste hierarchy. One of the actions indicated in the legal solutions is expansion, retrofitting, and construction of new sorting plants, anaerobic digestion plants, composting plants, and increase in thermal treatment capacity. Variety of different processes that could emit odors and a diversity of different odor-generating substances released from particular waste management steps should be taken into consideration when building new facilities which are suitable for waste treatment. The overall aim of the work was to characterize and summarize available knowledge about waste management system in Poland and to gather information about odor-generating substances emitted from different waste management steps and facilities, which could be a potential source of information for preparing legal solutions to reduce possible odor nuisance form broadly understood waste management.
