Ecotechnologies for the recovery of nitrogen and phosphorus from anaerobic digestate: Effectiveness of products as fertilisers

This research paper review examines the effectiveness of ecotechnologies, specifically struvite precipitation and ammonia stripping, for recovering nitrogen and phosphorus from the liquid phase of anaerobic digestate to provide plant nutrients and renewable energy while reducing environmental waste impact.

• The liquid phase of anaerobic digestate serves as a concentrated source of nutrients, and two promising technologies for recovering these nutrients are ammonia stripping and struvite precipitation.
• Combining anaerobic digestion with nutrient recovery technologies on digestate allows for the simultaneous production of plant nutrients and renewable energy.
• Increasing the recycling of nutrients from organic waste streams back into agriculture is required to improve rural–urban sustainability.
