D2.5. BBFs production and characterisation vs. time (list, average composition, and composition variability)

Abstract

The FERTIMANURE concept integrates a set of innovative treatment schemes to efficiently valorise animal manure and to obtain fertilizing products with high added value. FERTIMANURE pursues the improvement of several technologies that are either currently under development or that have been successfully used for similar applications and proposes innovative integrated solutions to finally reach a zero-waste manure management approach. In WP 2, five different on-farm pilots were implemented during the first year of the project, and they have been operated and optimised from M13 to M42. WP2 activities were implemented by partners having different profiles: scientific partners (UVIC, LEITAT, WENR, RITTMO, UGENT, FHR), farmers (APF, CPV, APCA), public bodies (DARP, APCA) and technology providers (DORSET). During the demonstration period the inflow and outflow streams for each on-farm pilot were monitored, and the quality of the BBFs was determined and optimised within Task 2.2. Analytical ad hoc protocols were proposed for each BBF to assess its quality in terms of physical, physic-chemical properties, and the presence of toxic chemical elements and molecules, and pathogens. Results from Task 2.2 were necessary for the activities of other FERTIMANURE WPs as follows: • WP3 (Production of tailor-made fertilisers and quality assessment): BBFs characteristics are needed to allow the formulation of tailor-made fertilisers (TMFs). • WP4 (Demonstration of the end-products performance: incubation, pot-tests, and field trials): BBFs characteristics are needed to set up experimental assessment of BBFs and TMFs. Deliverable 2.5 aims to provide information about the characterisation of BBFs produced in the five FERTIMANURE pilots after optimisation. This deliverable is divided into six subsequent chapters. First, a brief introduction describes the context in which the research is carried out. The second chapter summarizes the array of chemical analyses to be used to characterize the BBFs. Then, the third chapter reports the results from the BBFs characterisation that was carried out during the operation of the pilot plants. The following chapter describes the optimisation work performed during the operation of some pilot plants to obtain BBFs of higher quality. Afterwards, chapter 5 will compare the obtained BBFs characteristics with what is stated in literature. Lastly, the report ends with a general evaluation of Task 2.2 at M48.
