A low-temperature, catalytic tertiary conversion process for recycling organic materials is proposed for application to turkey litter and other animal waste. This platform technology delivers rapid capture of valuable nutrient resources in a closed, nonpolluting system and can maintain the physical properties of materials treated or reduce them into a fine, dense ash. Current environmental problems associated with disposal of poultry and swine wastes provide excellent opportunities for use of this recycling technology to minimize the volume of litter, manure, and mortalities requiring disposal; sterilize litter material for reuse in multiple rotations; and reclaim valuable nutrient and mineral resources using a safe, closed system.

Recycling reactors based on this technology are easily adapted for permanent on-farm installation as well as truck-mounted portable units. This technology should provide economically viable treatment options for poultry and swine waste streams even before the values of reclaimed resources are considered. Successful deployment of this technology to poultry and livestock producers will result in increased food and worker safety, reduced risk of environmental contamination, enhanced producer profit margins, and increased rural property values. Related technologies are being commercialized for recycling scrap plastics and electronic, aircraft, and automotive parts.
