Abstract
The conventional processing of sweet potatoes produces a very strong caustic waste that is high in organic matter. Present technology does not emphasize recirculation or other control of water use. Improved technology is available such as high pressure low-volume water sprays and a dry caustic peeling process that reduce water use and convert the liquid caustic waste to a semi-solid waste that can be disposed of in sanitary landfills or sold as cattle feed. Developing technology offers the potential of lye recovery, an improved steam peel or an infrared dry caustic peel that increases yield. In-plant control of waste through process modification and/or treatment is economical and may even provide a net return on investment. Biological treatment is effective.
