Adsorption of organic micropollutants onto biochar: a review of relevant kinetics, mechanisms and equilibrium

“…In this section, biochar surface properties are discussed. Biochar surface properties depend on the characteristics of feedstock biomass, the pyrolysis process, and post-pyrolysis handling/treatment of biochar 16,45 .…”

Sub-Pilot-Scale Autocatalytic Pyrolysis of Wastewater Biosolids for Enhanced Energy Recovery

“…The biosolids derived bio-oil can also be co-digested anaerobically to produce more renewable fuel (i.e., biogas) via specific pretreatment or using acclimated biomass [42]. Therefore, the autocatalytic pyrolysis process can be coupled with other existing technologies and applications to simultaneously enhance energy recovery, minimize adverse environmental impacts, and generate value-added products from wastewater [43,44].…”

Comment on “Pyrolysis of dried wastewater biosolids can be energy positive”

“…Public health, pathogen reduction, and pollutant removal must also be considered while reducing energy demands. Biosolid pyrolysis has potential benefits of yielding a valuable soil amendment product (Carey, McNamara, & Zitomer, 2015;Liu et al, 2018), sequestering carbon (Singh, Cowie, & Smernik, 2012), reducing the concentration of emerging contaminants returned to land (Hoffman, Zitomer, & McNamara, 2016;Kimbell, Kappell, & McNamara, 2018;Ross, Zitomer, Miller, Weirich, & McNamara, 2016), and recovering energy from dried biosolids (Liu, McNamara, & Zitomer, 2017).…”
