Beyond its use as fertilizer and biogas, are there more ways to recycle manure? Smithfield Foods thinks so. This week, the company announced it joined USDA, EPA and other environmental leaders as a participant in the Nutrient Recycling Challenge, a competition to develop affordable technologies that recycle nutrients from livestock manure.
For more than two decades, Smithfield has transformed anaerobically digested manure into a second useful life as fertilizer and biogas, but the company hopes to build on these efforts by identifying more effective and affordable solutions to recycling nutrients in order to build a more sustainable future.
