Manure processing as a pathway to enhanced nutrient recycling by Sari Luostarinen, Elina Tampio, Johanna Laakso, Minna Sarvi, Kari Ylivainio, Kaisa Riiko, Katrin Kuka, Elke Bloem and Erik Sindhöj

The need to introduce new nutrients into the current demand from mineral resources could be reduced significantly via nutrient recycling. The most significant recyclable material is animal manure which is traditionally used as a fertilizer. However, due to segregation of crop and animal production, manure is often regionally concentrated so that its nutrients may be available in excess to the region’s need. To enable regional nutrient reallocation, manure processing to various end-products could be used. In this report the advantages and challenges of manure processing are discussed and several processing technologies introduced.

Typical pitfalls leading to gaps between envisaged and realised impacts of manure and nutrient related projects – a gap analysis by H. Lyngsø Foged (Corresponding author, Organe Institute), A. Szymanski (CDR), E. Sindhöj (RISE), K. Kuka (JKI), M. Krystoforski (CDR), M. Sarvi (Luke), S. Kaasinen (HELCOM), Z. Melnalksne (Zemnieku Saeima)

This report describes potential pitfalls in project design and implementation that could cause gaps between envisaged and realized project impacts to promote sustainable manure management. The analysis looks at possible reasons for these gaps and suggests improvements to enhance policy impact of projects in the future.

Technologies and management practices for sustainable manure use in the Baltic Sea Region by Erik Sindhöj, Marek Krysztoforski, Katrin Kuka, Sari Luostarinen, Zanda Melnalksne, Kristina Mjöfors, Kaisa Riiko, Kalvi Tamm, Kari Ylivainio, Minna Sarvi

The objective of this report was to compile recommendations from seven previous Interreg and Bonus projects dealing with improving manure use in the Baltic Sea Region. The recommendations were sorted according to where along the manure handling chain they should be implemented and synthesized in terms of the various aspects of sustainability they aimed at improving.


SuMaNu Policy Recommendations

Policy recommendation 1: Development of coherent P fertilisation policies in the Baltic Sea Region

Policy recommendation 2: Fertilization planning and nutrient balancing

Policy recommendation 3: National standards for handling and spreading manure

Policy recommendation 4: Regional nutrient reallocation

Policy recommendation 5: Minimal use of harmful substances and careful manure processing ensure safe recycling of manure nutrients

Policy recommendation 6: Knowledge transfer between farmers, advisors, researchers, authorities, and policymakers
