Tightening regulations on biosolids disposal and growing energy utilization increase the operational costs of wastewater treatment plants, and reduce the sustainability of municipal infrastructures. In response, the wastewater industry is converting from only treating wastewater for environmental protection to additionally recovering resources wasted with the water. In terms of energy content, recoverable organics and nutrients (nitrogen, phosphorus) account for ~15% of the per capita electricity consumption; accordingly, recovery will improve sustainability and reduce CO2 footprint. However, recovery using current aerobic biological processes is limited. Thus, the current program will contribute to the development of new anaerobic biological processes enabling recovery. The results will improve infrastructure efficiencies and reduce burden to tax payers.

收紧对生物固体处置的监管和不断增长的能源利用增加了污水处理厂的运营成本，并降低了市政基础设施的可持续性。作为回应，污水处理行业正在从只处理环保废水转向额外回收与水一起浪费的资源。在能量含量方面，可回收有机物和养分(氮、磷)约占人均用电量的15%；因此，回收将提高可持续性并减少二氧化碳足迹。然而，使用目前的好氧生物工艺进行回收是有限的。因此，目前的计划将有助于开发新的厌氧生物工艺，使之能够进行回收。这一结果将提高基础设施效率，减轻纳税人的负担。
