- Current FW valorization methods have limitations impacting efficiency and scalability.
Purpose of the Study:
- To review and assess key food waste valorization techniques.
- To explore the potential of producing high-value chemicals from food waste.
- To propose strategies for enhancing FW valorization through technological integration.
Main Methods:
- Review of thermochemical (pyrolysis, gasification, hydrothermal carbonization) methods.
- Assessment of biological (composting, anaerobic digestion, microbial fermentation) processes.
- Evaluation of green extraction techniques (cold plasma, supercritical fluid, microwave-assisted extraction).
Main Results:
- FW valorization offers sustainable solutions, moving beyond simple biofuel production to high-value chemicals.
