Anaerobic mono- and co-digestion of coffee pulp (CP), cattle manure (CM), food waste (FW) and dewatered sewage sludge (DSS), were assessed using biochemical methane potential tests. The effects of two different inocula, anaerobically digested cattle manure (ADCM) and anaerobically digested waste activated sludge (ADWAS), and five different co-feedstock ratios for CP:CM and FW:DSS (1:0, 4:1, 2:1, 4:3, and 0:1) on specific methane yields were also evaluated. Mono-digestions of both CP and FW yielded the highest methane yield compared to the co-digestion ratios examined. Furthermore, no synergistic or antagonistic effect was observed for any of the co-digestion ratios tested. Nine different kinetic models (five conventional mono-digestion models and four co-digestion models) were compared and evaluated for both mono- and co-digestion studies. For CP:CM, cone and modified Gompertz with second order equation models were the best-fit for mono- and co-digestion systems, respectively, while for FW:DSS, superimposed model showed the best-fit for all systems.

咖啡果肉 (CP)、牛粪 (CM)、食物垃圾 (FW) 和脱水污水污泥 (DSS) 的厌氧单消化和联合消化使用生化甲烷潜力测试进行评估。两种不同的接种物、厌氧消化的牛粪 (ADCM) 和厌氧消化的废物活性污泥 (ADWAS) 以及 CP:CM 和 FW:DSS 的五种不同共同原料比率（1:0、4:1、2: 1、4:3 和 0:1) 对特定甲烷产率的影响也进行了评估。与检查的共同消化率相比，CP 和 FW 的单一消化产生了最高的甲烷产量。此外，对于所测试的任何共同消化率，均未观察到协同或拮抗作用。对九种不同的动力学模型（五种传统的单消化模型和四种共同消化模型）进行了比较和评估，用于单消化和共同消化研究。对于CP：
