The suitability of the co-digestion of feedstock-mixtures (by-products and agricultural residues) depends on their ability to produce biogas. In this study, the effects of mixing five feedstocks (citrus pulp, olive pomace, poultry manure, Italian sainfoin silage and opuntia fresh cladodes) on anaerobic digestion for biogas production have been investigated by carrying out biomethane potential (BMP) tests on six different mixing ratios of the selected five biomasses. The BMP test results demonstrated that all the six studied feedstock-mixtures could be potentially used for renewable energy generation by biogas plants. More in detail, two mixing ratios of the studied feedstock-mixtures showed the best biomethane potential of 249.9 and 260.1 NmCH/tVS, respectively. Since this research study made it possible to screen the suitability and technical feasibility of the feedstock-mixtures analysed, the results provide the basis for subsequent pilot scale evaluation of anaerobic digestion in Mediterranean area, where by-products and agricultural residues are profuse and necessary to produce advanced biofuels.
原料混合物（副产品和农业废弃物）的共消化适宜性取决于它们产生沼气的能力。在这项研究中，通过对选定的五种生物质的六种不同混合比进行生物甲烷潜力（BMP）测试，研究了混合五种原料（桔皮、橄榄渣、家禽粪便、意大利三叶草青贮料和仙人掌鲜刺）对沼气生产的厌氧消化的影响。BMP 测试结果表明，所有六种研究的原料混合物都可以通过沼气厂用于可再生能源的产生。更详细地说，两种研究的原料混合物的混合比分别显示出最好的生物甲烷潜力，分别为 249.9 和 260.1 NmCH/tVS。由于这项研究使得筛选被分析的原料混合物的适宜性和技术可行性成为可能，因此结果为随后在盛产副产品和农业废弃物的地中海地区进行沼气消化的中试规模评估提供了基础，这些地区需要生产先进的生物燃料。
