Under the Teholanta project, solutions are sought for the recycling of poultry manure that are directly applicable to farms. In the same context, water protection can be intensified.
“The Teholanta project was born at the initiative of producers. Interest in the efficient use of poultry manure exists, and producers would like to see more appreciation for manure” says Reetta Palva, project manager at TTS.
“The target is to create sample solutions that can be duplicated and be readily applied at farms to the recycling of valuable nutrients.”
The Teholanta project focuses on the overall sustainability of manure processing, taking both the ecological and economic perspective.
Tests involve the incineration of manure, its thermal gasification and biogasification, and the utilisation as fertilisers of the end products thus generated.
“We have already noticed that the manure of commercial layer chicken generates more biogas per fresh weight unit than the manure of other poultry. We have plans to demonstrate the biogasificaton of various manures under real farm conditions”, says Sari Luostarinen, Principal Research Scientist at Natural Resources Institute Finland (Luke).
“In a suitable form, poultry manure is an excellent nutritional supplement for the fields of our contract producers. On the other hand, at the moment, phosphorus contained in poultry manure is a problem, and its recovery should absolutely be examined. Developments in the sector will benefit all parties”, says Jarmo Seikola, Procurement Manager at HKScan, justifying the participation of the company.
The Teholanta project is a joint project of TTS, Natural Resources Institute Finland, the Finnish Environmental Institute, Suomen Siipikarjaliitto Oy (Finnish Poultry Association) and the JAMK University of Applied Sciences.
The operators receive support provided by separate funding for water protection and nutrient recycling under the Rural Development Programme. Atria Suomi, HKScan, MTK, Maa- ja vesitekniikan tuki ry and Siipikarjasäätiö (the Finnish Poultry Foundation) also participate in the project.
