Workshop: Advancing Anaerobic Digestion of Wastewater Solids and Food Waste for Energy and Resource Recovery: Science and Solutions Location: Alexandria, VA. Date: June 5, 2017.

1632734 fillmore带厌氧沼气池的水资源回收设施可以通过将食物垃圾与废水固体共消化来增加沼气的产量，用于能源回收。用于共消化的大部分非废水有机材料是食品垃圾，通常来自食品工业运营、商业食品垃圾和机构或住宅来源的消费后食品垃圾。产生的沼气（甲烷）可用于供热、发电和/或发电。本次研讨会将为最佳实践的发展提供重要的科学基础，以确保通过共同消化适当设计和实施可再生能源回收的好处，并尽量减少副作用，从而减少目前实践的这一过程。本次研讨会还将讨论联邦政府的一项目标，即通过废水固体和食物垃圾等可再生原料促进沼气利用和扩大沼气工业。据估计，目前位于美国的100个水资源回收设施进口有机废物与废水固体共消化。随着共消化的实施，一些城市收集厌氧消化器性能和操作的经验数据。利用水资源回收设施内已建成的基础设施，将食物废物与废水残渣共同消化，转移堆填区的有机废物，并以具竞争力的能源成本，以可持续的方式回收食物废物中的能源。然而，用于预测添加食物垃圾的沼气池性能的可用数据远远少于仅用于废水固体的数据。了解科学和操作实践之间的关系对于使共同消化成为公用事业公司实施的有效过程至关重要，从而成为处理食物垃圾和促进可再生能源回收的可行选择。通过科学改进厌氧消化的过程和实践是有潜力的。本次研讨会将为共消化提供一个技术、经济和实用的框架，并确定当前和未来的研究差距、工艺改进和控制点。水环境研究基金会（WERF）建议举办一个研讨会，将研究成果和推进厌氧消化和共消化的科学与WRRF AD从业者的需求相结合。世界经济论坛有条件召开这次研讨会并传播其成果。WERF拥有270多名成员，代表了大部分下水道人口，并在共消化方面进行了8年的研究，已成为行业领导者。

1632734FillmoreWater resource recovery facilities with anaerobic digesters can increase their production of biogas for energy recovery through co-digestion of food waste with wastewater solids. Much of the non-wastewater organic material used in co-digestion is food waste, typically from food industry operations, commercial food waste and post-consumer food waste from institutions or residential sources. The biogas (methane) produced can be used to generate heat, power, and/or electricity. This workshop will provide a significant scientific basis for the development of best practices to ensure the benefits of appropriately designed and implemented renewable energy recovery through co-digestion with minimization of side-effects that can curtail this process as currently practiced. This workshop will also address a Federal goal to promote biogas utilization and expand the biogas industry through renewable feed-stocks such as wastewater solids and food waste. It is estimated that 100 water resource recovery facilities located in the United States currently import organic waste for co-digestion with wastewater solids. As co-digestion is implemented, some municipalities collect empirical data on anaerobic digester performance and operations. The co-digestion of food waste with wastewater residuals using the built infrastructure at water resource recovery facilities, diverts organic wastes from landfills and recovers the energy in food waste in a sustainable manner at a competitive energy cost. However, there are far less data available to predict digester performance with the addition of food wastes than for wastewater solids alone. Understanding the relationships between the science and operational practice is essential to make co-digestion an efficient process to be implemented by utilities so to become a viable option for food waste disposal and promote renewable energy recovery. There is potential to improve the process and practice of anaerobic digestion through science. This workshop will provide a technical, economic and practical framework for co-digestion, and identify current and future research gaps, processes enhancements and control points. The Water Environment Research Foundation (WERF) proposes to hold a workshop to integrate research findings and advance science on anaerobic digestion and co-digestion with the needs of WRRF AD practitioners. WERF is well positioned to convene this workshop and disseminate the results. With more than 270 members representing much of the sewered population, and 8 years of research on co-digestion, WERF has become the industry leader.
