Life Cycle Inventory & Assessment Report: Cooling of Manure, Applied to Fattening Pigs Slurry, Denmark


The Manure Cooling Technology reduces ammonia emissions in the housing units, which leads to a higher N content in the manure (which might increase nitrate leaching). The technology is based on a heat pump, which requires electricity; however, it also produces heat that can replace other sources of heat for e.g. heating the housing units for the pigs. The environmental consequences of the technology are not straightforward: What are the environmental advantages and disadvantages of applying manure cooling in the housing units for fattening pigs?


The environmental impacts has been evaluated along the “manure management chain” from in-house storage, outdoor storage and to application of the manure to field in combination with the environmental impacts from the energy production for the manure cooling, by use of consequential Life Cycle Assessment (LCA).


This report on Manure Cooling was prepared as part of Work Package 5 on Assessing Sustainability of Manure Technology Chains in the project Baltic Manure.
