Solid-State Fermentation: A New Way to Turn Waste into Valuable Products

What is it about?

The research explored the potential of solid-state fermentation (SSF) to treat and valorize organic waste by transforming it into valuable bioproducts. The research highlighted SSF's similarity to composting, while emphasizing its goal of producing bioproducts such as enzymes, biopesticides, and bioplastics. A key focus was the integration of SSF with anaerobic digestion, utilizing solid digested materials as substrates, thereby yielding both renewable bioenergy and bioproducts. The research identified challenges in scaling up bioreactor design and optimizing downstream processes, which are critical for commercial viability. Furthermore, the study outlined the role of machine learning and artificial intelligence as promising tools for overcoming scale-up issues. The research underscored the necessity for additional studies to refine downstream processing, ensuring the production of high-quality end products at competitive costs.
