The focus was on how the pretreatment Lignocellulosic biomass aﬀects the biodegradability, methane production, and proﬁtability of thermochemical dispersion disintegration Disintegration (TCDD) based on liquefaction and soluble lignin. The TCDD process was eﬀective at 12,000 rpm and 11 min Lignin under the optimized thermochemical conditions (80 °C and pH 11). The results from biodegradability tests imply Methane that 30% liquefaction was suﬃcient to achieve enhanced biodegradability of about 0.280 g-COD/g-COD. When biodegradability was > 30% inhibition was observed (0.267 and 0.264 g-COD/g-COD at 35–40% liquefaction) due to higher
