“…It clearly shows that IVOC accounted for the major fraction (37–62%) of components. The high fraction of IVOC indicates that combustion emission played an important role in urban PM 2.5 . In addition, besides the uncertainty of this volatilty estimation method, sampling artifact (e.g., IVOC in the gas phase absorved on quartz-fiber filters) and the higher sensitivity to the extraction solvent of methanol and reversed-phase C18 column for IVOC compared to LVOC and ELVOC may overestimate the fraction of IVOC in the urban PM 2.5 samples .…”

Volatility of organic aerosols (OAs) significantly influences new particle formation and the occurrence of particulate air pollution. However, the relationship between the volatility of OA and the level of particulate air pollution (i.e., particulate matter concentration) is not well understood. In this study, we compared the chemical composition (identified by an ultrahigh-resolution Orbitrap mass spectrometer) and volatility (estimated based on a predeveloped parametrization method) of OAs in urban PM 2.5 (particulate matter with aerodynamic diameter ≤ 2.5 μm) samples from seven German and Chinese cities, where the PM 2.5 concentration ranged from a light (14 μg m −3 ) to heavy (319 μg m −3 ) pollution level. A large fraction (71−98%) of compounds in PM 2.5 samples were attributable to intermediate-volatility organic compounds (IVOCs) and semivolatile organic compounds (SVOCs). The fraction of low-volatility organic compounds (LVOCs) and extremely low-volatility organic compounds (ELVOCs) decreased from clean (28%) to heavily polluted urban regions (2%), while that of IVOCs increased from 34 to 62%. We found that the average peak area-weighted volatility of organic compounds in different cities showed a logarithmic correlation with the average PM 2.5 concentration, indicating that the volatility of urban OAs increases with the increase of air pollution level. Our results provide new insights into the relationship between OA volatility and PM pollution levels and deepen the understanding of urban air pollutant evolution.

“…Comparison of advantages and disadvantages of the combustion process[55][56][57].COMBUSTION Technology widely known and used on a massive scale, high availability of boilers and infrastructure,  The technological process does not raise objections from society due to its universality,  Combustion reduces up to 90% of the volume of the burned material.  Combustion releases carcinogenic compounds such as dioxins and furans, as well as increases the emissivity of greenhouse gases and other air and atmosphere pollutants.,  The need to adapt an expensive exhaust gas treatment system,  The greatest source of low emission is heat production (the combustion of low-quality fuels in boilers).…”

The main goal of the study was to assess the possibility of practical use of products of pyrolysis of refuse-derived fuel (RDF), i.e., pyrolysis gas, biochar and pyrolysis oil, as an alternative to standard fossil fuels. The subject matter of the paper reaches out to the challenges faced by the global economy, not only in the context of the energy crisis, but also in the context of the energy transformation currently beginning in Europe. The increase in fuel and energy prices prompts countries to look for alternative solutions to Russian minerals. At the same time, the growing amount of municipal waste forces the implementation of solutions based on energy recovery (the amount of municipal waste per EU inhabitant in 2021 is 530 kg). One such solution is pyrolysis of RDF, i.e., fuels produced from the over-sieve fraction of municipal waste. In Poland, insufficient processing capacity of thermal waste conversion plants has led to significant surpluses of RDF (1.2 million Mg of undeveloped RDF in Poland in 2021). RDF, due to their high calorific value, can be a valuable energy resource (16–18 MJ/k). This issue is analyzed in this study.
