Anaerobic co-digestion of sludge from recycled pulp and paper industry (RPPS) with vinasse effluent from alcohol distilleries (VW) was performed under mesophilic conditions (37 °C) at laboratory scale, using one-liter continuous stirred tank reactors (CSTRs). The physicochemical parameters were monitored during the process. The average pH and alkalinity were 7.7 and 1000 mg CaCO₃ Kg⁻¹, respectively, indicating that the process is working well without the risk of acidification. The methane yield and biodegradability of this mixture were determined. The methane yield was about 112 (NmL CH₄ g⁻¹ VS added) and biodegradability reached 73%. Nevertheless, in monodigestion of RPPS, the methane yield was 94 (NmL CH₄ g⁻¹ VS added) and biodegradability 65%. The anaerobic co-digestion of (RPPS) with (VW) at a proportion of (70:30) improved methane production by 16% and biodegradability by 11%. Bioenergy recovery from industrial (RPPS) is promoted by co-digestion with (VW), and the removal efficiency of 73% indicates the performance of the process adopted. A kinetic study was performed using five models Richards, modified Gompertz, Logistic, Cone, and first order. The results show that Richards' was the most appropriate model for adjusting methane production from (RPPS) and (VW) co-digestion.

使用一升连续搅拌釜式反应器，在实验室规模的中温条件下（37°C），对废纸浆和造纸工业（RPPS）的污泥与酒精蒸馏厂（VW）的酒糟废水进行厌氧共消化。在该过程中监测理化参数。平均pH和碱度分别为7.7和1000 mg CaCO ₃  Kg ^-1，表明该工艺运行良好，没有酸化的风险。测定该混合物的甲烷产率和生物降解性。甲烷产率为约112（加入NmL CH ₄  g ^-1  VS），生物降解性达到73％。然而，在RPPS的单消化中，甲烷产率为94（NmL CH ₄ 添加 g ^-1 VS）和65％的生物降解性。（RPPS）与（VW）比例为（70:30）的厌氧共消化可将甲烷产量提高16％，并将生物降解性提高11％。与（VW）共消化可促进从工业（RPPS）回收生物能源，其73％的去除效率表明所采用工艺的性能。使用五个模型的Richards，改进的Gompertz，Logistic，Cone和一阶模型进行了动力学研究。结果表明，理查兹（Richards）是最合适的模型，用于调节（RPPS）和（VW）共消化的甲烷产量。
