Mixed organic waste containing plastics, metals, or chemicals reduces digester efficiency and increases maintenance frequency.

Approximately 31% of facilities report inconsistent feedstock composition as a recurring operational concern. Seasonal agricultural harvesting patterns also affect biomass availability during different months of the year. Digesters require carefully controlled temperatures between 35°C and 55°C for optimal microbial activity, increasing operational complexity.
