Recovery of Phosphorus and Metals from the Ash of Sewage Sludge, Municipal Solid Waste, or Wood Biomass: A Review and Proposals for Further Use

Materials, Год журнала: 2023, Номер 16(21), С. 6948 - 6948

Опубликована: Окт. 29, 2023

This review provides an overview of methods to extract valuable resources from the ash fractions sewage sludge, municipal solid waste, and wood biomass combustion. The addressed here include critical raw materials, such as phosphorus, base precious metals, rare earth elements for which it is increasingly important tap into secondary sources in addition mining primary materials. extraction technologies prioritized this are based on recycled acids or excess renewable energy achieve optimum environmental profile extracted provide benefits form local industrial symbioses. cover all scarce chemical contained ashes above certain concentration limits. Another part defining potential applications mineral residues remaining after extraction. Therefore, aim combine knowledge resource technology with possible construction related sectors fully close material cycle loops.

Phosphorus-Related Ash Chemistry at High Temperatures: Role of Aluminum on Particle Adhesion

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(11), С. 4655 - 4661

Опубликована: Март 6, 2024

Phosphorus-containing ash generated from the thermochemical conversion of biomass is expected to be applied as a phosphorus resource. Handling important in utilization. In this study, effect Al, coexisting element ash, on P-related particle adhesion at high temperatures was investigated using synthetic ashes, which are model compounds understand phosphorus-related chemistry. Synthetic ashes containing P, Al and Si (P–Al–Si) were prepared, their adhesiveness quantified tensile strength 500–900 °C. Below 20 wt % increased slightly with increasing P concentration. At concentrations or higher, rapidly easily reacted derived resulting formation P–Al P–Al–Si compounds. Since slag these systems higher than that P–Si system, P-containing suppressed increase adhesion. On other hand, excess due Addition Al2O3 nanoparticles showed strongest for decreasing because phase promoted.

Recycling, Год журнала: 2024, Номер 9(4), С. 62 - 62

Опубликована: Июль 26, 2024

The concept of the circular economy represents most relevant mainstream approach to reducing negative environmental impact waste. Anaerobic digestion has proved be one leading and widely adopted techniques for sewage sludge treatment under principles economy. purpose this study is forecast economic indicators through modeling extensive utilization biogas technologies with a case an administrative territorial unit. proposed methodological framework involves use averaged specific based on relationship between inhabitants, waste generation rates, yield, greenhouse gas emission mitigation energy potential. widespread anaerobic according methodology in instant scenario will ensure yield 10 million Nm3 within considered territory unit population 4.2 P.E., which ultimately can expressed electricity thermal potential 20.8 24.8 kWh*y, respectively, annual elimination 119.6 thousand tons CO2 equivalent capital investment attraction EUR 65.18 million. Furthermore, all subjected disinfection stabilization procedures its safe utilization. findings offer opportunity wide range stakeholders assess benefits adoption technologies. developed utilized inform management decisions forecasts.
