Emissions at farm level (methane, particulate matter (fine dust), ammonia etc.) are modelled based on international standards, such as IPCC (2006) and EMEP/EEA (2016).
In the INNO+ tool, a benchmark and 4 improvement scenarios are modelled:
Benchmark scenario: a standard Dutch broiler production system. It does not include any air scrubbing system and has been modelled based on national average animal performances (Wageningen UR, 2017).
1. Airscrubber implementation: the first intervention consists in the use of an air scrubber (chemical or biological), with consequent abatement of ammonia and particulate matter from the air but requiring extra electricity and water.
2. Triple EEE (‘Energy, Efficient, Economic’) implementation: the second intervention consists of extracting heat from the exhaust air with the air scrubber and recirculate the heat to preheat the incoming air of the stable. This in order to reduce the risk of respiratory disease and consequent stress.
