Abstract This study aimed to characterize the carbon isotopic signatures (δ 13C-CH4) of several methane waste sources, predominantly in the UK, and during field campaigns in the Netherlands and Turkey. CH4 plumes emitted from waste sources were detected during mobile surveys using a cavity ring-down spectroscopy (CRDS) analyser. Air samples were collected in the plumes for subsequent isotope analysis by gas chromatography isotope ratio mass spectrometry (GC-IRMS) to characterize δ 13C-CH4. The isotopic signatures were determined through a Keeling plot approach and the bivariate correlated errors and intrinsic scatter (BCES) fitting method. The δ 13C-CH4 and δ 2H-CH4 signatures were identified from biogas plants (−54.6 ± 5.6‰, n = 34; −314.4 ± 23‰ n = 3), landfills (−56.8 ± 2.3‰, n = 43; −268.2 ± 2.1‰, n = 2), sewage treatment plants (−51.6 ± 2.2‰, n = 15; −303.9 ± 22‰, n = 6), composting facilities (−54.7 ± 3.9‰, n = 6), a landfill leachate treatment plant (−57.1 ± 1.8‰, n = 2), one water treatment plant (−53.7 ± 0.1‰) and a waste recycling facility (−53.2 ± 0.2‰). The overall signature of 71 waste sources ranged from −64.4 to −44.3‰, with an average of −55.1 ± 4.1‰ (n = 102) for δ 13C, −341 to −267‰, with an average of −300.3 ± 25‰ (n = 11) for δ 2H, which can be distinguished from other source types in the UK such as gas leaks and ruminants. The study also demonstrates that δ 2H-CH4 signatures, in addition to δ 13C-CH4, can aid in better waste source apportionment and increase the granularity of isotope data required to improve regional modelling.
Highlights Isotopic 13C signatures from 71 waste sources in UK, NL and TR determined. Feedstock types have an impact on carbon isotopic signature of generated biogas. Open and active landfill status has a great impact on carbon isotopic signature. Sewage treatment is more enriched in 13C than from other waste sources. Average δ13C isotopic signature of waste sources is −55.1 ± 4.1‰.
