The Role of Mild Alkaline Pretreatment in the Biorefinery Upgrade of Spent Coff...
Ribeiro, Gabriel Mota; Martins, Pedro L.; Oliveira, Ana Cristina; Carvalheiro, Florbela; Fragoso, Rita; Duarte, Luís C.ABSTRACT: This work proposes a valorization route for spent coffee grounds (SCG), a widespread lignocellulosic residue, encompassing the production of: biomethane, lignin, and oligosaccharides as value-added products obtained simultaneously during a mild alkaline (NaOH) pretreatment. The studied operational variables were the reaction time (60-240 min), temperature (25-75 degrees C), and the NaOH concentration ...

Ribeiro, Gabriel Mota; Martins, Pedro L.; Oliveira, Ana Cristina; Carvalheiro, Florbela; Fragoso, Rita; Duarte, Luís C.This work proposes a valorization route for spent coffee grounds (SCG), a widespread lignocellulosic residue, encompassing the production of: biomethane, lignin, and oligosaccharides as value-added products obtained simultaneously during a mild alkaline (NaOH) pretreatment. The studied operational variables were the reaction time (60–240 min), temperature (25–75 C), and the NaOH concentration (0–2.5 M). The sev...
