This category includes the following categories of technologies for biogas upgrade to biomethane: Pressure Swing Adsorption (PSA), Pressure Water Scrubbing (PWS), Membranes, Cryogenic, and Organic Physical Scrubbing (OPS). It includes an emission of 0,03 MJ CH_(4)/MJ biomethane for the emission of methane in the off-gases. This category includes the following categories of technologies for biogas upgrade to biomethane: Pressure Water Scrubbing (PWS) when water is recycled, Pressure Swing Adsorption (PSA), Chemical Scrubbing, Organic Physical Scrubbing (OPS), Membranes and Cryogenic upgrading. No methane emissions are considered for this category (the methane in the off-gas is combusted, if any). Biomethane production system Technological option Greenhouse gas emissions – typical value (g CO_(2)eq/MJ) Greenhouse gas emissions – default value (g CO_(2)eq/MJ) Biomethane from wet manure Open digestate, no off-gas combustion – 20 22 Open digestate, off-gas combustion – 35 1 Close digestate, no off-gas combustion – 88 – 79 Close digestate, off-gas combustion – 103 – 100 Biomethane from maize whole plant Open digestate, no off-gas combustion 58 73 Open digestate, off-gas combustion 43 52 Close digestate, no off-gas combustion 41 51 Close digestate, off-gas combustion 26 30 Biomethane from biowaste Open digestate, no off-gas combustion 51 71 Open digestate, off-gas combustion 36 50 Close digestate, no off-gas combustion 25 35 Close digestate, off-gas combustion 10 14
