Anaerobic bioconversion of food waste into energy: A critical review

- More than 400 papers in the last 5 years have been published on FW into energy.
- Food waste complexity and composition affects anaerobic conversion.
- Scaling up of the AD process is fundamental to assess the real methane potential.
- Methanogenesis is often rate limiting step leading to pH drop and instability.
- Strategies to improve AD performances and stability are here reviewed.
