Hydrothermal liquefaction (HTL) has attracted considerable attention for valorizing sewage sludge to biofuels while the solid residue, hydrochar, received little its final application. In current work hydrochar recovered from hot separation in a pilot-scale HTL plant is evaluated nutrient value, particular as sustainable Phosphorus (P) resource. Following thorough characterization of P recovery struvite (NH4MgPO4.6H2O) investigated produce fertilizer with lower heavy metal content that could be used agricultural practices. extraction using inorganic (hydrochloric and sulphuric) organic (citric) acids by applying 0.1- 1 mol/L 1- 12 h liquid/solid ratio 10 mL/g. A second-order polynomial model was established response surface methodology (RSM) predict different acids. The optimum operating conditions maximum (94%) are suggested 0.7 M acid strength (H2SO4) 6.5 time. Addition citric (CA) during precipitation acid-leached solution found improve purity 36.6% 54% reduction content. Furthermore, morphological analysis validated formation struvite. Upon comparison regulations, exceed some limits but low polyaromatic hydrocarbons (PAHs), per- polyfluorinated substances (PFAS) showed toxicity Aliivibrio fischeri. shown reduce contents below regulatory recoveries 40-67%. Thus, an alternative direct land application harvested applied no apparent environmental risk.
