Challenges Abound...

Poultry farming operations generate a large volume of waste comprised of raw manure, litter, and mortalities. This waste is typically stored as produced over the course of a year then land applied to crop acreage as a fertilizer in the fall. However, challenges associated with this practice abound:

  • Environmental impact - runoff pollution, critical element dilution loss, and odor
  • Government regulation - complex, burdensome, and potentially very costly fines
  • Economics - in areas of high production density waste transportation represents a significant cost

Many approaches to address these challenges have been explored or implemented on a limited basis, but typically suffer significant challenges which undermine their viability and impede widespread adaptation:

  • Operational issues - poultry waste is difficult to process effectively for a number of reasons resulting in complexity of operation, unacceptable uptime or maintenance requirements, polluting emissions, etc.
  • Economics - many alternate approaches require large scale of centralized implementation to approach economic feasibility, so associated high complexity and capital needs impede broad deployment
  • Emissions - due to the challenging chemical composition of poultry waste, it is very difficult to thermochemically process poultry waste without generating excessively polluting effluent streams, necessitating complex and expensive additional equipment/processes to cleanse effluent streams
