Abstract

An international project on energy recovery from biomass is described for organic wastes, such as agriculture residues and crops grown for energy recovery. The bioconversion to fuel gas of all these is based on “controlled landfilling”, a low-capital-cost batch digestion method associated with the managed recovery of methane from sanitary landfills. An engineering analysis predicts the digester size for small-scale biogas production. The digestibility of seven municipal and agricultural wastes in laboratory batch systems was experimentally determined by eight investigators on five continents. The reported bioconversion ranged from 0.1 to 0.4 m3 biogass per kg substrate. The relative consistency of the results offers encouragement to evaluate the fuel-gas generation potential in developing countries. An appendix presents a mathematical model of a landfill bioreactor.

结合有机残留物生产低资本成本燃气-全球潜力
介绍了一个从生物质中回收能源的国际项目,用于有机废物,如农业残留物和为回收能源而种植的作物。所有这些生物转化为燃料气体的基础是“控制填埋”,这是一种低资本成本的批量消化方法,与从卫生填埋地管理回收甲烷有关。工程分析预测了小型沼气生产的沼气池尺寸。由来自五大洲的八名调查人员对实验室批处理系统中七种城市和农业废物的消化率进行了实验测定。报告的生物转化率为每千克底物0.1至0.4立方米。研究结果的相对一致性鼓励了对发展中国家的燃气发电潜力进行评价。附录中给出了垃圾填埋场生物反应器的数学模型。
