Optimizing earthworm stocking density for process efficiency and compost maturity in food waste and sewage sludge vermicomposting

Key Points

• Improved compost maturity occurs with optimized stocking density in vermicomposting, enhancing food waste processing.
• Stocking density adjustments lead to significant changes in compost maturation timelines, measured over eight weeks.
• Observational analysis on food waste and sewage sludge vermicomposting evaluated the impact of varying earthworm populations.
• Findings support optimizing earthworm density for better composting outcomes, indicating a need for further validation.
