This deliverable contains the outcomes of our exploitation task in the project Circular Agronomics. Five technologies, namely solar drying, microfiltration, vacuum degasification, K struvite recovery and membrane treatment had been transferred to a potential replication site and been evaluated under these large-scale conditions. The studies consider a site description, the integration of technology into the site, a cost estimation, a forecast on emissions, legal aspects to be considered and finally some conclusions on roll-out and/or further technology development. To date the technologies reached TRL 6 or 7 and are applied to solid or liquid fraction of agricultural digestate or wastewater and waste streams from food industry. The scale of installations varies from concept studies for a capacity less than 1 m³/h towards 15 m³/h resulting in different cost profiles. A cross-cutting conclusion on different influencing factors such as technology readiness, their environmental benefits, their cost sufficiency and political factors influencing potential replication is delivered. The final paragraph of each concept study concludes with the recommendations for technology provider and or site owner in terms of further development and provides answers about uncertainties in terms of investment decisions. A further synthesis of the main finding of this work will be published in Deliverable 6.9 - a brochure about the technologies.

As part of their communication activities, multi-actor approach projects are required to produce short “practice abstracts” (PAs) which outline their plans and main findings. The information should be easy understandable and provided throughout the project’s life-cycle. This information must therefore be shared in a specific format (the “EIP Common format”) which is specially made so that project info and results can be shared with those who can apply the findings. The format includes: a short and understandable title, a succinct summary of the issue tackled and the main outcomes and recommendations produced, and contact details to find further information. The content of the submitted practice abstracts can be updated at any moment according to new findings.

Circular Agronomics, aims to foster the transition from a linear economy to a circular economy. Therefore, this deliverable focuses on circular solutions for waste and wastewaters originating from the food industry. In 2019, the “Best Available Techniques (BAT) Reference Document for the Food, Drink and Milk Industries” (BREF-document) was published by the European Commission. Based on that, the deliverable summarizes the state of the art of the technologies already in use and concludes their suitability for circular economy solutions. In Circular Agronomics, new technologies for the recovery of carbon, nitrogen, phosphorus and potassium are developed and investigated. So far, those technologies are not included in the BREF-document yet. Therefore, the concepts of the technologies are introduced in the deliverable. For a potential integration of those technologies in the BREF-document, the technologies are described in detail in the annex according to the required structure in the BREF-document. However, since the technologies are still under development, those descriptions are considered as a first draft. The authors suggest to update those descriptions at a later stage of the project prior to their potential integration in the BREF-document. Referring to the goal to recover carbon and nutrients, the deliverable presents a detailed characterization of the waste and wastewaters originating from the food industries. Based on that, the five most promising waste and wastewater streams regarding carbon recovery, nitrogen recovery, phosphorus recovery and potassium recovery were selected. For those streams and the corresponding recovery technologies four new concepts are suggested in the deliverable. In order to show the technology providers an overview of potential clients for their technologies and for those concepts, for each selected industry, the European country with the highest production rate was chosen. For this country, the regional distribution of the certain industry was determined.
