dc.description.abstractLaboratory-scale anaerobic degradation of monoethanolamine waste (MEAw) with co-substrate organics was conducted at roomtemperature and organic loading rates from 0.19 to 5.03 kg COD/m3 day for 486 days in a hybrid digester. 90 % feed COD conversion tomethane was obtained at the lower loads and only 45 % at the highest MEAwaste/COD ratio (MEAwr) of 0.62 due to inhibition of methanogenesis. Inhibition at comparable loads decreased with time, implying that the culture adapted to the challenging feed. Methane yield was negatively correlated to MEAwr applied and inhibition avoided at MEAwr\0.5. Acetate accumulation implies inhibition of acetoclastic methanogenesis that can be caused by ammonia, a product of MEAw degradation. Moderate total ammonia nitrogen and free ammonia nitrogen accumulation, maximum 2.2 g N/l and 90 mgN/l, respectively suggests, however, that other components of MEAw, and/or degradation products of such, also inhibitmethanogenesis, disturbing the digester performance.no
