Ammonia emissions from the pig livestock: from a problem to a fertiliser resource
Gas Loop has developed and monitored an air washing system that removes ammonia from the air of the stables, recovering it in an ammonium sulphate solution to increase the animal welfare and productivity due to better air quality inside the pig housing. The pig livestock becomes more sustainable, the ammonia concentration in the rooms where the air is treated by Ammonia Washing Machine is 62% lower than in untreated rooms and the ammonia emissions into the atmosphere are reduced by 54% (ammonia emission avoided for 1,94 kg NH3/animal place per year). The ammonia reduction in the pigsties improves animal welfare, the pig's lungs health and the health of workers. The best breeding conditions increase the feed conversion rate and nitrogen use efficiency. The device draws ammonia rich-air from the stable through suction ducts located below the slatted floor and the air treatment is based on the chemical absorption of ammonia by counter-current acid washing into a tower. The process take place at pH 4.5 and sulfuric acid solution is used as absorbent matrix.

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).
