Dewatering and granulation of sewage sludge by biophysical drying and thermo-degradation performance of prepared sludge particles during succedent fast pyrolysis

► Novel biomass recovery using fast biophysical drying (BPD) coupling with fast pyrolysis. ► Extreme thermophilic amendment and enhanced convective evaporation combined in BPD. ► BPD adjustment contributed for moisture removal, fragmentation, and organic preservation. ► Fabricated BPDS bio-particle exhibited good features for residue-derived energy. ► BPDS fast pyrolysis was characterized by hydrogen-rich gas generation.
