Anaerobic Digestor of Organic Waste Processing: A Biomass Energy ProductionProjectAbstract:Biogas is produced when organic matter is degraded in the absence of oxygen. The process, fromdegradation to gas production is called anaerobic digestion. The research in this study focuses on thefeasibility of the design and implementation of an operational digester, the monitoring and control of thedifferent biodegradation process variables and experiments to boost or maximize the gas production. Ourgoals in this phase of the study are: (i) to get an understanding on the characteristics of organic wastefrom hotels and restaurants and study the feasibility of implementing the proposed anaerobic digester forbiogas production for District of Columbia hotels and restaurants, and (ii) to build a mini anaerobicdigester that can generate biogas in the laboratory and to provide preliminary data and identify keyaspects of the design for an efficient, reliable, and low-cost anaerobic digester for waste processing. Thespecific research objectives for goal (1) include understanding of organic waste collection methods inhotels and restaurants and possible quantification of organic waste. The research methodology include(i) Preparation of survey questioner to collect the data about the current generation and wasteprocessing of organic waste from a variety of sources, (ii) Implementation of survey through site visits, (iii)Quantification of daily organic waste and evaluation of waste processing through the experimentalanaerobic digester. The specific research objectives for goal (ii) include design of a small scale anaerobicdigester that can be operated with a minimum of monitoring, regulating, and adjusting and optimization ofthe experimental condition to maximize the amount of biogas produced per unit time with the proposedmini digester. The research methodology includes (i) design and fabrication of laboratory scale minianaerobic digester, and (ii) analysis of the content of the biogas produced by the proposed mini digesterusing Gas Chromatography (GC) under different experimental conditions.
