In some Mediterranean areas coexist intensive livestock and agricultural production systems, which, although highly vulnerable to global warming, also play a role among its causes. Current emission inventories give importance to slurry management and fertilization activities as sources of greenhouse gas (GHG) and ammonia (NH3) emissions. 

Agriculture is often faced with the widespread application of inefficient slurry management techniques and, in some cases, the abuse of bad practices such as over-fertilization with excessive amounts of organic and mineral fertilizers. This hinders the environmental and economic sustainability of agricultural activity in rural areas and results in GHG emissions, excessive consumption of mineral fertilizers, inefficient energy schemes, excessive road transport, etc., in addition to other no less important issues such as NH3 emissions.

Goal of

 This project aims at developing sustainable and resource-efficient slurry management models that approach the idea of “climate-neutral farms”. These models will be supported by the development and validation of robust monitoring methods that reliably evaluate the results obtained. 

The partners will apply simple and innovative techniques in the three key stages of slurry management (in-house production + storage + agricultural fertilization) to mitigate CH4, N2O and NH3 emissions, recover methane generated in storage, valorise biogas and surplus heat in biomethane production processes as renewable energy sources for farm activities and/or adjacent industries and reduce mineral fertilizer consumption, all in accordance with the principles of the circular economy.  These models will be analysed from an environmental and socioeconomic point of view by developing measurement and monitoring methodologies that provide objective data.
