“…The P-recovery from WAS incineration ashes is also under investigation nowadays [177][178][179][180]. These ashes contain high amounts of P, mainly due to the considerable volume reduction of up to 90 % [181].…”

“…The mineral composition of the ISSA can vary for different plants; however, but in many publications the above-mentioned mineral phases are common [e.g. 8,10,11,19], with the only differences being in their amount and the morphology. The APC residues comprise light gray, very fine material, where particles below 100 µm constitute over 95 vol%, and the water-soluble material content is ca.…”

To support the rational management of raw materials in the European Union more attention is being paid to the resource potential of waste materials, which are increasing in volume due to industrial development and the world population growth. One of the methods to reduce the amount of produced and landfilled waste is incineration. As a result of sewage sludge incineration, fly ash (ISSA-incinerated sewage sludge ash) and APC (air pollution control) residues are produced. The goal of this study was to characterize incineration residues from waste water treatment plant in Polish city with ca. one million inhabitants using mineralogical, chemical methods, and to estimate the recovery potential of valuable components. Both incineration products accumulate elements which are of valuable concentrations, such as P (17 wt% of P 2 O 5 on average in the ISSA), as well as significant amounts of metals such as Zn, Pb, Cu, Ni, and Cr. Small particle sizes < 125 µm in both materials favor the accumulation of elements of higher volatility during incineration, but they are usually dispersed within a matrix, main minerals or amorphous substance, or are present in the form of micro inclusions or grains < 10 µm, which thus excludes their easy recovery.

“…Another interesting option is a recovery of phosphorus from sludge ash. The P-recovery from ash after sludge incineration is under wide investigation nowadays [18,19]. A two-step thermal treatment is suggested.…”

In 2015, the European Commission has adopted an ambitious Circular Economy Action Plan (CEAP), which includes measures that would help stimulate Europe’s transition towards a circular economy. In general four key action areas have been defined: production, consumption, waste management and secondary raw materials. Actions will lead to the resource-efficient and environmentally friendly outcomes. Biological materials should be returned to the natural metabolic cycles after necessary pre-treatment while waste that can not be prevented or recycled is to be used for the energy recovery. Sewage sludge is a large-tonnage waste produced at wastewater treatments plants (WWTPs). Its utilization causes some problems. High water content in sludge, hazardous substances as heavy metals, organic toxins and pathogens limit some potential methods of sludge utilization. Thermal treatment methods offer a solution, some hazardous substances can be destroyed or removed, energy can be recovered and some nutrients can be obtained from ash or other by-products.
