Technologies needed to turn food residuals into a drier, more economical and acceptable feedstuff are explained. Some of the methods used for processing fruit and vegetable residuals include dehydration, pressing, screen separation, and an activated sludge process. Some other possibilities include ensiling and the use of chemicals such as sodium hydroxide, or the use of organic acids such as propionic or formic acid. Techniques for blending or processing food wastes to result in a more uniform product may also improve utilization by the commercial feed industry.
