“…TP concentrations in biosolids‐derived char increased by 40% to 50% at 700°C, indicating P was associated with the inorganic fraction of biosolids (Hossain et al, 2011; Yuan et al, 2015). Due to less biomass lost during pyrolysis, TP concentrations in char are lower than concentrations in incinerator ash, which can be as high as 14% (Table 4; Krüger et al, 2014; Ma & Rosen, 2021). High concentrations of TP in incinerator ash may increase its potential as a fertilizer, but it is bound in mineral forms that are not readily available to plants (Gorazda et al, 2017; Ma & Rosen, 2021).…”

High P concentrations are also a challenge for reuse as a construction material due to detrimental effects on the strength of cement (Ottosen et al, 2013; Ottosen et al, 2020).…”

“…According to the survey, approximately 20% and 25% of the sewage sludge produced in the United States and the European Union are incinerated, respectively [10]. In addition, The sludge after incineration contains a lot of beneficial elements (such as P, N and K), which can be recycled for land use [11].…”

“…A wide range of organic wastes may be used, either directly or following appropriate treatment, in the biological and/or chemical reclamation of degraded areas [1]. For this purpose, municipal sewage sludge (MSS), which is predominantly sourced from wastewater treatment plants, can be used [2,3]. Another aspect is directly related to MSS itself, whose ever-increasing volume requires safe management methods to be developed [4].…”
