Effect of Gas Loop innovation on the environmental sustainability of the pig livestock
The environmental sustainability of the innovation was analyzed by applying the Life Cycle Assessment (LCA) methodology. The study calculated the environmental impact of the conventional management of pig farming (control) compared to the innovative one (Gas Loop)in which the air is treated by the system and renewable ammonium sulphate is produced. The boundaries of the study system include in the control and innovative thesis the feed and electricity used in breeding, the impact of raising the young pigs entering the fattening phase and the emissions of CH4, N2O and NH3 of the respective two thesis. In addition, for the innovative thesis all impacts for the construction and operation of the treatment system (electricity, reagents and materials) and the environmental benefit due to the ammonium sulphate produced were considered. The LCA analysis estimated the Carbon Footprint, the acidification and the formation of particulate matter derived from the heavy pig fattening. The results show that the carbon footprint by applying the innovation is equivalent to the control, i.e. 437.5 kg CO2 eq/head for the Gas Loop thesis compared to 438.3 kg CO2 eq/head for the control. The environmental benefit linked to the production of the renewable fertilizer is partly offset by the emissions linked to the treatment (construction, maintenence and consumables). The Gas Loop thesis, on the other hand, by limiting ammonia emissions, is effective in reducing the acidification phenomenon and the formation of particulate matter compared to the control, by 21% and 17% respectively.

A Bio-inspired Multilayer Drainage System
Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY
This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
