ESNI Community – Working Groups


As core part of this initiative, the ESNI community set up 4 Working groups, led by European projects, discussing major challenges with an impact on the nutrient recycling and recovery. At present, the following working groups are active:

  • Technologies for nutrient recycling coordinated by FERTIMANURE;
  • Agronomic performance of fertilising products coordinated by LEX4BIO;
  • Sustainability assessment coordinated by NOVAFERT;
  • Policy coordinated first by NUTRI2CYCLE and currently led by RENU2CYCLE.

  • Technologies for nutrient recovery

This working group focuses on revising and discussing innovative technological approaches for recovering nutrients from different side streams. It aims to boost collaboration among different projects by sharing their scientific findings, bottlenecks and limitations identified, solutions and cases of success.

Discover the outcomes below!

Upcoming activities:

  • Agronomic performance of fertilising products

This working group aims to gather all the knowledge related to assessing the agronomic performance of fertilising products, including laboratory and field testing. Discussion on methodologies used, analysis done, quality assessment etc., are relevant aspects of its activities.


Upcoming activities:

  • Webinar on quality assessment of bio-based fertilisers (date to be confirmed)
  • Sustainability assessment (environmental, economic and social)

Projects in this working group cooperate towards finding common approaches for assessing sustainability aspects of the technologies and recovered nutrients. In this regard, efforts are made to discuss common goals, scopes and methodological choices for developing coherent life cycle inventories.

More information on the upcoming activities will be available soon.

  • Policy

This group aims to thoroughly analyse the regulatory framework affecting the practical use, application and commercialisation of potentially recovered products. Identifying regulatory bottlenecks and potential solutions is expected to work on preparing joint position papers of the projects participating in reaching policymakers and regulatory stakeholders.


More information on the upcoming activities will be available soon.
