“…Phosphates are found in digestate and are easily available for plants [ 124 ] and can be recovered from the liquid in the form of struvite [ 125 ]. It has been shown that the addition of calcium can have a beneficial effect on the isolation of phosphorus from swine manure, increasing its recovery from 60 to 74%, while improving its ability to be separated into high P content calcium phosphate granules (nearly 80%) [ 126 ].…”

Phosphorus is one of the most important macronutrients needed for the growth of plants. The fertilizer production market uses 80% of natural, non-renewable phosphorus resources in the form of phosphate rock. The depletion of those deposits forces a search for other alternatives, including biological waste. This review aims to indicate the most important ways to recover phosphorus from biowaste, with particular emphasis on wastewater, sewage sludge, manure, slaughter or food waste. A comparison of utilized methods and directions for future research based on the latest research is presented. Combining biological, chemical, and physical methods with thermal treatment appears to be the most effective way for the treatment of wastewater sludge in terms of phosphorus recovery. Hydrothermal, thermochemical, and adsorption on thermally treated adsorbents are characterized by a high phosphorus recovery rate (over 95%). For animal by-products and other biological waste, chemical methods seems to be the most optimal solution with a recovery rate over 96%. Due to its large volume and relatively low phosphorus content, wastewater is a resource that requires additional treatment to recover the highest possible amount of phosphorus. Pretreatment of wastewater with combined methods seems to be a possible way to improve phosphorus recovery. A compressive evaluation of combined methods is crucial for future research in this area.

“…Sin embargo; existen reportes donde se ha implementado el postratamiento en efluentes de sistemas anaerobios que han tratado AR de industrias de lácteos, porcinas, agrícolas entre otros en los que la recuperación de estruvita ha sido viable, lo que se atribuye principalmente a altas concentraciones de fosfato y amonio (Huang et al, 2016a(Huang et al, , 2016bSchott et al, 2022). Por lo que el uso de la metodología planteada para la recuperación de estruvita variando las condiciones de pH y/o concentraciones de los componentes del mineral estudiado, favorecería al proceso de tratamiento de aguas que presenten efluentes con las condiciones ya mencionadas.…”

In this work, different decentralized wastewater treatment systems were evaluated, preselected for the treatment of gray water generated in a house in Iztapalapa of the type "Unique house on land with average occupants of 4”. Housing defined as a case study, taking as a reference the Mexico City mayor's office that presents greater problems of availability of piped water and coverage of wastewater treatment. The evaluation of the systems was carried out through the following phases: Phase 1. Indicators that contribute to the sustainability of the systems were identified and pondered, these being: demand for the system area, as well as its robustness, pollutant removal efficiency, investment costs, energy requirements, greenhouse gas emissions, landscape damage, odor emission and generation of byproducts whit economic or reuse value. Phase 2. The possible systems to be installed in the case study were pre-selected: sequential batch reactor, membrane biological, upflow anaerobic, as well as constructed wetlands and septic tanks. Based on these systems and the previously defined indicators, the available technical information was compiled. Phase 3. A decision matrix comprised the indicators, their weighting, and the preselected systems. Based on the information obtained in Phase 2, the systems were evaluated according to their compliance with each indicator. Once the evaluation was settled, it was weighted to obtain the qualification by alternative. Thus, the upflow anaerobic reactor obtained the highest rating (72.4 points), followed by the sequential batch reactor with only 2.8 points below. Given this result, the systems were compared based on the following criteria: a) Effluent quality and greenhouse gases from the systems operation products: where the sequential batch reactor presented better quality effluents and lower greenhouse gas emissions. b) Environmental impact of the treatment of gray water from the case study: the results showed that the sequential batch reactor was the most environmentally sustainable option.

“…A biological recovery could be simple and inexpensive. However, in pig and cattle manure, approximately 80% and 90% of the phosphorus is present in suspended material, respectively [37,38], being unavailable for biological recovery. For enabling biological recovery of more phosphorus from animal manure, pig and cattle manure would need to be diluted with significant amounts of water to increase the presence of phosphate ions [36].…”
