Event Description Please provide a detailed description of your proposed event. Viewing wastewater treatment as the integrated resource recovery of water, biosolids, nutrients, and energy has been beneficial in the planning process at both privately and publicly owned facilities. Recognizing the interfaces between water, energy, air, soil and transportation has helped usher holistic solutions which satisfy the economic, environmental, social, and operational objectives of the owner. An integrated approach to maximizing the resource potential of our water sector facilities will be the driving challenge of our industry through the next decades. There is an interrelationship between water, energy, air, soil and transportation and this provides an opportunity to develop synergistic solutions that maximize the potential of these resources. Sustainable solutions with multiple benefits can be realized by taking a holistic, integrated approach to planning. Sound value-based decisions can be made by viewing wastewater treatment as a process to recover water, biosolids, nutrients, and energy. Economic, environmental, social, and operational objectives can be met to satisfy a multi-faceted bottom line. Organic waste can be diverted from a landfill and fed to anaerobic digesters to produce biogas and biosolids. Biogas can be fed to cogeneration systems or it can be processed into biomethane and compressed to fuel compressed natural gas (CNG) vehicles. Energy can be recovered from sludge incineration or carbon can be sequestered by the land application of biosolids. Biosolids management alternatives have different air quality impacts and carbon footprints, along with physical footprints and economic issues. This workshop will provide an overview of the major resource opportunities and shed light on their role in the resource nexus. Topics of discussion will include: incineration with energy capture, soils, gasification, heat drying, air emission and organic waste management. Please list at least three learning objectives for this event. Demonstrating how the WWTP is a resource center at the heart of a potential opportunity to integrate water, energy, air, soil and transportation assets Defining the economic value of each of the resource opportunities available and determining applicability to individual WWTP operations Defining the environmental implications including greenhouse gas emissions, carbon footprint and trucking impacts. Examining other non-economic criteria such as operator flexibility and public perceptions to the various approaches and technologies. Highlight any hands-on or interactive components of your event.
