Sustainable valorization of food waste for microalgal production of value-added compounds, bio-oil, and biochar

Key Points

• The aim is to explore strategies for converting food waste into valuable microalgal products, reducing environmental impact.
• Utilized food waste as a substrate for microalgal cultivation.
• Assessed the production of bio-oil and biochar from microalgae.
• Analyzed greenhouse gas emissions before and after the process.
• Increased microalgal yield by 30% using food waste as a nutrient source.
• Generated bio-oil with 20% higher energy content compared to traditional methods.
• Reduced greenhouse gas emissions by 25% in the upcycling process.
