Abstract
Anaerobic digestion of the organic fraction from municipal solid waste offers the possibility of producing alternative energy from the produced biogas. Currently, there are eight biogas plants in Poland, where municipal waste is the feedstock for the fermentation process, but in the future, it is likely that much more will be built. For this reason, it is very important to characterise the sources of odour emissions in the plants in order to prevent complaints from residents of the region. The paper presents results of preliminary research in the field of identification and characteristic of odour sources in two selected biogas plants processing municipal waste in Poland: Wólka Rokicka-WR and Stalowa Wola-SW. The basic sources of odour were identified in relation to the biological treatment process and the pre-treatment of waste. The odour intensity and the concentration of odour and leading impurities were analysed. Results of the research of various technological solutions carried out in biogas plants were compared. The majority of big concentrations of odour and odorants are related to the operation of the biological part of both plants. The study revealed a strong dependency between the applied operation procedures, technological regime and the obtained measurement results. The highest correspondence between the results was obtained in both tested installations in the case of odour intensity and odour concentration, and in the case of concentration of NH3 and VOC.
Highlights
Biogas plants processing municipal waste are environmentally friendly investments
The paper presents the effects of local visions at two mechanical–biological waste treatment plants, involving the identification of the basic sources of odour emissions
The innovation potential is the identification of odour sources in biogas installations processing municipal waste both in relation to the biological treatment process and the pre-treatment of waste
Summary
Biogas plants processing municipal waste are environmentally friendly investments. Problems related to public health, land use, resource loss and climate change result in stringent rules on organic waste disposal, and more searches are being undertaken to increase reduction, recycling and recovery of useful materials from waste. A key element that is technically and economically viable for recovery is energy from organic waste fractions of municipal solid waste [1]. Municipal solid waste management is one of the most current challenges from the point of view of sustainable economy for future generations [2,3,4]. Food consumption and changes in chemical composition [4, 8] due to technological progress in the following areas in the food industry make the treatment of municipal solid waste a very important issue [9], which can be solved by various methods: thermal [4, 10] and more sustainable biological methods with energy recovery [4, 11]
