The paradigms of sustainability, the circular economy and the bioeconomy are a European priority for boosting competitiveness, creating jobs and generating sustainable growth. These approaches are particularly applicable to the management and treatment of wastewater and organic waste, including livestock manure.
The European Commission has recently published a reference document on the Best Available Techniques (BAT) for the intensive rearing of poultry and pigs, which identifies the BAT for the treatment of pig slurry on farms, and describes struvite precipitation as an interesting emerging treatment. The document also states that there is still a lack of knowledge and successful experiences in situ for it to be considered a consolidated technology. Similarly, the Government of Catalonia does not consider the precipitation of K-struvite a consolidated method for the treatment of livestock manure. As a result, the situation described within the framework of this project is an opportunity to develop an innovative treatment that will require the definition of specific guidelines for application in the livestock farming sector. The project will boost the implementation of a slurry treatment system aimed at nutrient recovery.
