Enhanced directional butyric acid production and phosphorus fixation in kitchen waste fermentation by potassium ferrate

Key Points

• Butyric acid production increased significantly during fermentation, enhancing overall yield.
• The metric of butyric acid improvement reached levels up to 30% with potassium ferrate addition.
• Analysis of kitchen waste fermentation processes indicated effective phosphorus fixation alongside butyric acid production.
• The approach suggests a sustainable method for waste utilization, although further field trials may be necessary.
