SummarySummarySummarySummary
! Wastewater facilities are a potential resource t f t bi lid dcenter for water, biosolids, and energy
! Biosolids are a valuable resource! We can think in terms of maximizing the
conversion of resources rather than minimizing biosolidsminimizing biosolids
! Anaerobic digestion of organic waste has the potential to meet the plant energy demand
! Distributed resource centers can be integrated for reclaimed water, biosolids, and
tenergy management
