Answer:
Recycled Ammonia 
Explanation:
Ammonia can be extracted from livestock wastewater and used as a fertilizer. There are systems available that extract the ammonia and mix it with acids to create ammonium citrate or ammonium nitrate, both of which can be used as fertilizers. The extraction system removes ammonia from the waste, which significantly reduces the amount of ammonia that is released into the air. This has the added bonus of improving the air quality where animals are kept.
