Fugitive halocarbon emissions from working face of municipal solid waste landfills in China

Trace gas emissions from municipal solid waste landfills: A review

“…A more recent study conducted by Liu et al (2017) and carbon tetrachloride). The production of ODS in China was banned in 2010, which was at least 10 years later than the more developed European countries and the USA, meaning that many halogen-containing products have not or just reached the end of their lives and will go into the waste stream, thus resulting in high emissions from landfills.…”

“…Halogenated compounds are xenobiotic and derive from the direct volatilisation of compounds contained in dry-cleaning solvent, refrigerants, aerosols, foam-blowing agents, soft foam plastics, paint remover and fire extinguishers (Allen et al, 1997;Hodson, 2008;Liu et al, 2017;Slack et al, 2005;Young and Parker, 1983). Some of the simpler halogenated compounds can be produced from the degradation of higher molecular halogenated compounds; for example, vinyl chloride can be generated through anaerobic hydrogen/halogen substitution of tetrachloroethylene and trichloroethylene in waste (Vogel and McCarty, 1985).…”

“…S2), and the highest concentration in raw LFG has been reported by Tassi et al (2009) at 5.8⋅10 4 µg m -3 for tetrachloroethylene. In addition, considerable amounts of CFCs have also been detected in several studies, probably due to the disposal of CFC-containing products (Liu et al, 2017). Vinyl chloride, albeit at relatively lower concentrations in raw LFG (average concentration was 1.9⋅10 3 µg m -3 ), might pose a carcinogenic risk to human health when released into the air.…”

“…Reference Source type (Schuetz et al, 2003) S3. (Liu et al, 2018(Liu et al, , 2017(Liu et al, , 2016b, measured between 2014-2015.…”

Mitigation of methane and trace gas emissions through a large-scale active biofilter system at Glatved landfill, Denmark

“…Some species are often associated with odour problems and provoke opposition from surrounding residents (Fang et al, 2012;Lim et al, 2018;Palmiotto et al, 2014). Compounds such as benzene and vinyl chloride are known carcinogens (de Sá Borba et al, 2017;Durmusoglu et al, 2010;Yaghmaien et al, 2019), while chlorofluorocarbons (CFCs) can contribute to ozone depletion and global warming (Hodson et al, 2010;Liu et al, 2017;Wallington et al, 1994). Hence, the establishment of mitigation measures is necessary to reduce gaseous emissions from landfills.…”
