Spent coffee grounds biochar from torrefaction as a potential adsorbent for spilled diesel oil recovery and as an alternative fuel

A new approach using torrefied spent coffee grounds (TSCG) as a bioadsorbent is presented for marine oil spill recovery. The adsorbent after diesel adsorption is referred to as “oilchar”. The torrefaction of spent coffee grounds (SCG) is performed at 200, 250, and 300 °C where the solid yields are 9...
