Development of an infrastructure for the reduction of emissions in intensive animal husbandry and the storage, processing and deduction of sensor data

The aim of the project is to develop an infrastructure for the permanent monitoring and, based on this, the reduction of the harmful gas and and dust pollution in intensive farming fattening barns. On the one hand this is related to the demands of agriculture to achieve maximum economy and competitiveness in livestock production. On the other hand, a reduction, by up to 50%, of ammonia pollution in the the barns will greatly benefit the health of both staff and animals and in turn reduce the need for medication. The increased cleanliness of the exhaust from the barns, with the relevant verification, will also lead to increased acceptance by the local communities of any new construction or extension of animal barns near residential areas. Within this project the focus initially is on the harmful gas pollution and ammonia reduction in piggeries. The approach will be designed to be relatively easy to transfer to the housing of other animals, like cattle.

Application of the to be developed technology will, for the first time, enable the sustainable reduction of harmful gas pollution. This will include associated documentation and therefore be verifiable. Perpetual documentation of this pollution is also required by the new European Union legislation on the continuous monitoring of harmful gases in animal housing.

In summary there are three technical focal points:

Development of sensors for harmful gases, especially ammonia, based on a new infrared measurement technique that is suitable for application in animal housing. The sensor will be applicable in single gas measurement systems, as well as integrated in stationary or mobile measuring systems for stable atmospheres.

Development of a sensor circuit board that allows, not only the capture of ammonia data, but also the addition of further sensor types at run time. The board will contain interfaces suitable for the connection of hardware/software controllers for the control of stable climate improvements components, such as filters and gas scrubbing. Cooperation partner Barntec UG will take on the development of the sensors, the sensor circuit board and the hardware/software control. They are a business partner with experience in agricultural sensor development.

Development of a software engineering Smart-Data-Infrastructurewhich will take a barn's captured sensor data from the Hardware/Software controller, and derive control rules for optimal barn climate, based on statistical models and machine learning techniques. It will also enable long term documentation of harmful gas pollution. Based on the continuous transmission of measured harmful gas concentration data, as well as additional climate affecting data, the Smart-Data-Infrastructure will continually adapt the control rules and transmit these to the hardware/software controller. Within consideration of the existing infrastructure, optimal barn climate will be generated by best possible reduction of harmful gas pollution.
