According to the European Union Directive 2009/28/EC, the goals of obtaining 20% of all energy requirements from renewable sources and a 20% reduction in primary energy use must be fulfilled by 2020. In this work, an evaluation was performed, from the environmental and energy point of view, of anaerobic digestion as a valid solution for the treatment of the byproducts obtained from the coffee-roasting process. In particular, thermophilic anaerobic digestion tests were carried out. Output values from the laboratory were used as input for the MCBioCH₄ model to evaluate the produced flow of biogas and biomethane and two different biogas valorization alternatives, namely, the traditional exploitation of biogas for heat/energy production and biomethane conversion. The results of the preliminary simulation showed that a full-scale implementation of the coffee waste biogas production process is technically feasible and environmentally sustainable. Furthermore, the performed analysis validates a general methodology for energy production compatibility planning.

用可能的解决方案的模型评估对生咖啡烘焙沼气进行评估

根据欧盟指令2009/28 / EC，到2020年必须实现从可再生资源中获取20％的能源需求并减少20％的一次能源使用的目标。在这项工作中，从环境和能源的角度来看，厌氧消化是一种有效的解决方案，可用于处理咖啡烘焙过程中产生的副产物。特别地，进行了高温厌氧消化测试。实验室的输出值用作MCBioCH _4的输入该模型可评估沼气和沼气的生产流量，以及两种不同的沼气增值替代方案，即用于热量/能源生产和沼气转化的传统沼气开采方法。初步模拟的结果表明，咖啡渣沼气生产过程的全面实施在技术上是可行的，并且在环境上是可持续的。此外，执行的分析验证了能源生产兼容性计划的通用方法。
