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.

This has the added bonus of improving the air quality where animals are kept.
