Recupero del fosforo nella sessione di laurea di luglio

Over the last few decades, there has been a growing understanding of the finite nature of phosphorus supplies and the significance of phosphorus recovery. Municipal wastewater sludge is a phosphorus source worth investigating since modern technology may transfer over 90% of phosphorus from the wastewater to the sludge fraction. Sewage sludge incineration is one of the most prevalent sludge management techniques, with benefits including volume reduction, eradication of pathogenic microbes and hazardous organic compounds, energy recovery, and production of valuable byproducts. On average, sewage sludge ash (SSA) has been reported to contain 11.6% P2O5 (a form and content comparable to P-rock ores). This thesis aims to examine and review existing technologies for recovering phosphorus from SSA, then provide an estimate of each method’s material and energy flows based on data available in the literature and provided by technology demonstrators. Furthermore, the different approaches regarding the Life Cycle Assessment (LCA) of the mentioned technologies and their environmental impacts in current literature are investigated.
