Innocuous iron oxide nanocrystals dissolve at the demand of methanogenic archaea in order to boost their metabolic activity increasing thus biomethane production and: the increased biomethane production is concomitant with a stabilization of the process and a reduction of the digestate volume and reactivity; the final digestate is enriched in iron ions being a better fertilizer. Increased anaerobic digestion translates into an increased sanitation and process acceleration. Reducing foam due to its particulate nature, keeping a healthy the bacterial consortium, promotes degradation of recalcitrant matter and rescue of sick digestors. Iron also precitpitates SH and P and atenuates pH increase.
