The White Paper sets out recommendations for stakeholders and policymakers, including establishing a harmonised EU definition for BBFs, creating a European BBFs Observatory, offering financial incentives, promoting long-term agronomic trials, and providing training to build social acceptance.

The BPB documents production methods, nutrient composition, field performance, environmental impact, and agronomic efficiency of BBFs, including nitrogen-loaded zeolites, algae powder, Bio-NPK-C compounds, Smart BBFs, recovered salts, and ammonium sulphate. It presents results from pilot trials, maturity upscaling, and lessons learned, supported by harmonised evaluation protocols and SWOT analyses.

The document acts as a guide in bridging the integrated WalNUT technological solutions with market and user acceptance. It addresses those partners who are developing market-competitive technologies and products to be demonstrated at TRL5 on a large scale.

This deliverable focuses on the on standardisation of common terminology in a joint understanding with other European projects. In addition, it provides a harmonised protocol for field evaluation of the agronomic efficiency of bio-based fertiliser in the WalNUT project

The document presents a summary of the results obtained in the tasks of nutrient recovery technology at lab scale, focusing on the best combinations of technologies and feedstocks. Comparisons between different technologies with the same aim, different feedstocks, pre-treatments, adsorbents or regenerants are included.

The research aimed to study and optimise the operational conditions of the technology proposed in WalLAB for nitrogen recovery, to scale-up this technology in further WalNUT activities. In this regard, several tests were performed concerning ion exchange and membrane contactor technologies.
