- •
Recovery of both lactic acid (LA) and biogas from food waste (FW).
- •
The first-step reaction was LA fermentation using indigenous mixed culture.
- •
LA extraction from the broth by nanofiltration and water-splitting electrodialysis.
- •
LA-fermented solid residue was fermented to biogas by anaerobic digestion.
- •
Recovery of 47 kg LA and 54 m3 biogas (60 USD/ton FW) from 1 ton FW.
