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

The document argues that recycling nutrients from organic waste streams is essential for rural-urban sustainability and global food security. It identifies the liquid phase of anaerobic digestate as a concentrated nutrient source and highlights struvite precipitation and ammonia stripping as promising recovery technologies that, when combined with anaerobic digestion, provide both renewable energy and plant nutrients.

• Recycling nutrients from organic waste streams back into agriculture is necessary to improve rural-urban sustainability and support global food security, which currently relies on animal manure and manufactured fertilisers.
• Struvite precipitation and ammonia stripping are identified as two promising technologies for recovering nutrients from the concentrated liquid phase of anaerobic digestate.
• Integrating anaerobic digestion with nutrient recovery technologies allows for the simultaneous production of plant nutrients and renewable energy.
