Proper treatment of waste-activated sludge (WAS) involves three pivotal processes,
dewatering, anaerobic digestion, and pollutants removal, which need to be re-assessed …

Poor and unpredictable dewatering performance of fecal sludge is a major barrier to
sanitation provision in urban areas not served by sewers. Fecal sludge comprises …

A “cradle-to-grave” life cycle assessment was conducted to examine the energy and
greenhouse gas (GHG) emission footprints of two emerging sludge-to-energy systems. One …

Landfill avoidance for organic wastes is now a high priority worldwide. Two fractions of the
