The total and available (water extracted) content of selected metal were determined in co-pyrolyzed SSL with willow (8:2, 6:2 w/w) at 500, 600, 700 °C using two different carrier gases (N2 or CO2). study investigated the relationship bioavailability to toxicity biochars towards bacteria (Vibrio fischeri), plants (Lepidium sativum), arthropods (Folsomia candida). For biochar produced a ratio 6:4 (SSL:willow), most metals significant decrease (P ≤ 0.05) from 5.9% 28.9%. Co-pyrolysis decreased water extractable concentrations (Ba, Cd, Cu, Fe, Mn, Ni, Zn) 8.0% 100%. CO2 resulted 6 200 % increase relative pyrolyzed N2. An pyrolysis temperature caused higher concentration biochars. 9 100 %. adverse effect these on living organisms was reduced due stronger binding (especially Cu Cd) matrix. negative impact Cr, also confirmed by principal component analysis (PCA).

Per- and polyfluoroalkyl substances (PFAS) are persistent organic chemicals detected in biosolids worldwide, which have become a significant concern for applications due to their increasing environmental risks. Hence, it is pivotal understand the magnitude of PFAS contamination implement effective technologies reduce prevent hazardous aftermaths. Thermal techniques such as pyrolysis, incineration gasification, biodegradation been regarded impactful solutions degrade transform into value-added products like biochar. These can mineralize compounds under specific operating parameters, lead unique degradation mechanisms pathways. Understanding pave way design technology optimize process conditions. Therefore, this review, we aim review compare thermal treatment incineration, smouldering combustion, hydrothermal liquefaction (HTL), biodegradation. For instance, perfluorooctane sulfonic acid (PFOS), firstly C-S bond cleavage occurs followed by hydroxylation, decarboxylation defluorination reactions form perfluoroheptanoic acid. In HTL, PFOS carried through OH-catalyzed series nucleophilic substitution reactions. contrast, involves three-step random-chain scission pathway. The first step includes cleavage, perfluoroalkyl radical, radical chain propagation Finally, termination produces very short-fluorinated units. We also highlighted important policies strategies employed worldwide curb biosolids.

Biochar is the solid residue that recovered after thermal cracking of biomasses in an oxygen-free atmosphere. has been used for many years as a soil amendment and general applications. Nonetheless, biochar far more than mere amendment. In this review, we report all non-soil applications including environmental remediation, energy storage, composites, catalyst production. We provide overview recent uses material science, thus presenting cheap waste-derived high value-added carbonaceous source.
