There are significant discrepancies between official inventories of emissions and estimates derived from direct atmospheric measurement. Effective emission reduction can only be achieved if sources are properly quantified, and mitigation efforts are verified. Stable isotope analysis is widely used to characterise sources. Methane from biogas plants is biogenic origin and can vary with waste feed type, temperature and production process, which results in variation of emissions with time of day and time of year. In addition, the sewage treatment plants and sugar beet factories produce biogas by combusting the sludge/ by-products and their emissions can also be identified by analysing the methane isotopic composition, as different source types are characterised clearly by distinct δ13C signatures. We report δ13C measurements for methane plumes emanating from 20 diverse biogas plants. Samples were collected during campaigns in 2018 and early 2019 in SE England and the Netherlands. The air samples were collected from anaerobic digesters of food waste, agricultural waste, sludge waste and sugar beet remaining pulp facilities. Even different waste feed type can cause distinct isotopic signatures, there is not a typical isotopic signature for each type of waste feed due to different production processes.
